Sealing Stone Outside

Limestone, Sandstone, Travertine, Marble, Slate, Granite, concrete:
Regardless of what type of flooring you choose, the likelihood is it will require some form of sealing.

This is because natural stone is porous, and therefore if left unsealed, any moisture will be soaked up by the stone making it very difficult to remove, and potentially leaving the surface permanently stained (sometimes even fallen leaves can cause stains).

The best way to prevent all this is to seal the stone.

When you seal a stone, you are essentially filling any voids or pores of the stone with the sealer. This prevents any further liquid to absorb in to the tile, as demonstrated here with this close up shot of a water droplet on a tile sealed with LTP Mattstone.

When sealing natural stone outside it is important to use a breathable impregnating sealer, this will allow the transition of moisture from underneath.
Examples include LTP Mattstone H20 which will leave the stone looking as it does naturally. And LTP External Stone Sealer which will enhance any natural colour in the stone, both of these are water based breathable sealers and will require 24 hours to cure.

It is important to note that all stones located outdoors are susceptible to a condition known as efflorescence.
This blooming is caused by water moving through the substrate of a material and carrying minerals and salts found in the mortar bed, grout, soil or the stone itself.
We have a blog here all about efflorescence.

Its also very important when laying Natural stone to make sure that its fixed on a full bed of adhesive and not spot fixed.
The end result could look like this if its spot fixed.
Spot fixing issue Sandstone

If this has already happened to your patio, we have a blog here.

When sealing different natural stones, what will vary the most will be how many coats the stone will need before it is fully sealed.
Each stone exhibits different levels of porosity. A tumbled Limestone may have a higher porosity level than a Honed and filled Limestone.

Sealing natural stone with Mattstone H20 

Shake bottle before use.

Test the porosity of your stone with water and a teaspoon, using the LTP porosity test.

Once surfaces are clean and dry, apply the product to the surface evenly using a sealant applicator pad, brush or soft cloth.

When sealing its important not to over apply the sealer and redistribute excess, avoid letting the sealer pool on the surface, as this can cause white marks to appear on the stone when it dries.
On highly absorbent surfaces apply several coats wet-in-wet.
After 15 minutes, remove any excess sealer with an absorbent cloth. Do not allow residues to dry on the surface.
Do not walk on the surface for 3 hours and protect from wet conditions for 3 days.

Sealing Stone With LTP External Stone Sealer.

Shake bottle well before use. Apply evenly to the surface using a foam roller or paint brush. On more absorbent surfaces apply further coats at hourly intervals until the surface is completely saturated. Remove any residual sealer if still visible after one hour

Cleaning Tiles Outside

Before you start sealing your stone it is important to make sure your stone is clean and dry, other wise you will just seal in dirt and grime.

Old layers of sealer, dirt residues and light deposits of organic matter and algae must be removed from the surface and pores of the stone.

This can be done by either using LTP Grimex which is a intensive cleaner or LTP Mouldex Paving Cleaner.

To Clean with LTP Grimex, dilute 1:3 with water, apply to the surface with a sponge or water brush and leave to sit on the surface of the tiles for as long as it takes for the dirt to release. (5-30 minutes depending upon the level of dirt). If areas look as if they are drying out just add a little more solution to keep the area wet.

Agitate the surface with a stiff deck brush after approx 10 minutes (scrubber machines can be used).

Continue to scrub while adding clean water. Remove residues from the surface with water or scrubber machine.

Rinse thoroughly with clean fresh water to remove all remaining residues. Use a power washer if necessary.

Allow the surface at least 24 hours to dry before sealing.

To clean with LTP Mouldex Paving Cleaner, Shake well before use.
Surfaces to be treated should be completely dry before application.
Pour solution undiluted directly onto the pavers and spread out evenly using a sponge or paint brush, Garden sprayers can also be used and leave for a minimum of 1 hour.

Apply a little water and agitate with a stiff Deck brush or emulsifying pad to release the dirt and grime, and then rinse thoroughly using a hose or jet wash.
Some stubborn stains and black spot may require a longer treatment, in which case apply and leave on surfaces overnight. If some black spot remains after treatment, It should fade and disappear after a few days following the treatment. If not: re-apply. Keep pets off at all times during treatment. In case of contact with metals, fabrics and painted surfaces rinse with water immediately. Do not use on warm surfaces. Do not apply if rain is imminent. Avoid contact with ponds & plant life: if contact is made rinse well with plenty of water.

General Maintenance.
Weekly or daily depending on conditions, use a hose and a brush to remove any debris that may be lying on the stone.
Then annually if required use LTP Grimex, this will remove surface dirt and grime, possibly every 6-12 months depending on condition.
Dilute Grimex 1:3 parts water and apply the solution on to the surface and agitate.
Leave for 10 minutes before agitating again and then rinse with water.
Allow 24 hours to dry and then if necessary re-apply a light coat of sealer.

PLEASE NOTE: Always follow the detailed instructions on the product labels. Protect stone surfaces from contact with acidic substances. Do not use abrasive materials on honed or polished stones. Avoid using normal detergents or strong bleach cleaners on sealed surfaces as they will gradually remove the protective seal.

Please note that this information is offered as general guidance only and without guarantee. Your specific circumstances may need an alternative approach. In case of doubt, any process should be tried out in an inconspicuous area before general application.

Cleaning, Sealing and maintaining stone surfaces

Cleaning, Sealing and Maintaining Stone Surfaces 

Natural stone has been used on floors and walls for centuries. As with all natural materials, it does need a certain level of care.

 

Natural Stone Surfaces – Internal Application

The following instructions are appropriate for Travertine, Limestone, Marble, Sandstone, Terrazzo and some Granite.

STEP ONE: INITIAL CLEANING 

Before sealing natural stone must be thoroughly cleaned to make sure that sealing of the surface can be achieved effectively. This is true of newly installed surfaces, as well as existing, due to the contamination that can occur during fitting. Equipment recommended for this step is a bucket, mop, white emulsifying pad, 4pcs pole, sealant applicator & pad holder, microfibre cloth, scrubber or scrubber dryer machine.Stone_cleaning_and_seal_Pack1

Newly installed surfaces

LTP recommends LTP Grimex as the solution for cleaning newly installed natural stone surfaces before sealing. LTP Grimex removes grease, dirt and grime from the surface ensuring the natural stone surface is best prepared for application of a sealing product.

Cleaning newly installed stone surfaces

  1. Dilute LTP Grimex 1:10 with water.
  2. Apply solution to the surface with a mop or sponge. Under floor heating must be off.
  3. Agitate to release the residual dirt and grime from the surface with a mildly abrasive pad (LTP White emulsifying pad).  Rinse well using a sponge & water.
  4. Do not use acidic cleaners, such as LTP Grout Stain Remover.
  5. Allow the surface to dry (preferably for 24 hours).

Cleaning natural stone with LTP Grimex

Refurbishing used and heavily soiled stone surfaces

  • Before sealing the stone must be thoroughly cleaned. Old layers of sealer, residues from aftercare products and deposits must be removed from the surface and pores of the stone. Film forming layers of sealer should be removed with LTP Solvex before washing with LTP Grimex.
  • Depending upon the levels of dirt, dilute LTP Grimex 1:3 with water. Apply with a sponge or cloth and leave to sit on the surface of the tiles for 5-10 minutes.
  • Agitate the surface with a white emulsifying pad (for polished, smooth or honed surfaces) or scrubbing-brush ( LTP Deck brush) for Rough Cut surfaces and leave for a further 5 minutes (scrubber machines can be used).
  • Continue to scrub while adding clean water. Remove residues from the surface using a cloth or scrubber dryer machine.
  • Rinse thoroughly with clean fresh water to remove all remaining residues.
  • Allow the surface to dry for a minimum of 24 hours before applying the protective seal.
  • For the removal of other types of dirt: Do not use acid based cleaners on limestone or marble. If you are unsure please call our helpline on +44 (0) 01823 666213 for advice.

STEP TWO: PROTECT YOUR NATURAL STONE SURFACE FROM STAINS

To protect stone surfaces and help prevent staining natural stone should be sealed. LTP recommends applying LTP Mattstone for a natural (invisible finish) or LTP Colour Intensifier & Stainblock for an enhanced appearance. LTP Colour Intensifier & Stainblock deepens the colour and enhances the appearance of the stone surface.

Sealing prepared natural stone surfaces

  1. Surfaces must be clean and dry. Ensure under floor heating is off.
  2. Apply the product to the surface evenly using either LTP sealant applicator,a sponge, brush or soft cloth.
  3. Redistribute to remove excess product and avoid pooling on the surface.
  4. Allow to dry. Do not walk on the surface for at least one hour.
  5. Protect from water for 24 hours and do not wash surfaces for at least 3 days.

Sealing natural stone with LTP Mattstone, LTP Mattstone H20 or LTP Colour Intensifier.

  • LTP Mattstone H20, LTP Mattstone and LTP Colour Intensifier will make the surface water and oil repellent.
  • Prevents stains, aids cleaning and simplifies the removal of surface stains.
  • Provides an invisible barrier of protection that will not greatly alter the surface character.
  • There are no health concerns once the product has properly cured.
  • LTP Mattstone H20, LTP Mattstone and LTP Colour Intensifier are micro porous and so can be used on surfaces that have no damp proof course.
  • Suitable for internal and external use.
  • If surfaces are properly maintained we recommend touching up the protective treatment every 3-4 years.

NB. Always test the product on an inconspicuous area. Wet or non absorbent surfaces cannot be treated. LTP Mattstone H20, LTP Mattstone and Colour Intensifier are impregnating sealers which need to fully absorb. Do not allow the product to dry on the surface. Carefully buff with a soft cloth or machine to remove any excess. Remove unabsorbed impregnating sealer, if left to dry on the surface, by rubbing over with a little more sealer. Some stones may be darker after application. Acidic substances, if left on the surface, may damage stone.

STEP THREE: MAINTAINING YOUR NATURAL STONE WALL OR FLOOR

Using the correct maintenance product will increase the life of your floor seal, provide additional protection against staining and make sure your floor looks great. Common household cleaning products often contain harsh substances that can breakdown sealing products applied to stone. For this reason LTP recommends using LTP Waxwash on floors and LTP Stonewash for surfaces.

LTP Waxwash (for floors): Formulated for use on unglazed tiles such as travertine, stone, limestone, slate, terracotta and quarry. Ideal for washing floors sealed with LTP Mattstone H20, LTP Mattstone or LTP Colour Intensifier. Use routinely in place of normal detergent.

LTP Stonewash (for walls): This gentle surface cleaner is formulated for use on limestone, marble, granite, slate and polished porcelain. Will clean without breaking down and removing protective seals.

Regular maintenance on stone floors

  1. Add one cap full of product per litre of water in a bucket.
  2. Wipe surface with the solution. Do not rinse.
  3. Allow to dry. Do not walk on the surface during drying time – 20 minutes.

Maintaining natural stone with LTP Waxwash

A one litre LTP Waxwash will wash a 20 sq.m floor 40 times.

PLEASE NOTE: Always follow the detailed instructions on the product labels. Protect stone surfaces from contact with acidic substances. Do not use abrasive materials on honed or polished stones. Avoid using normal detergents or strong bleach cleaners on sealed surfaces as they will gradually remove the protective seal.

Sandstone-Fixing & Sealing Outside.

Featured

We have recently been contacted by numerous customers who have been having problems with spot stains appearing on their sandstone patios.

Sandstone Flags with Spot Fixing Issues.

Sandstone Flags with Spot Fixing Issues.

This is a common problem, so we thought we should share why and how this issue sometimes occurs. The pictures in this post are supplied by customers showing the problems that are occurring.

 

Understanding Sandstone

Many of the imported sandstones, and some limestones and granites,are very porous. If fixing natural sandstone or limestone outside DO NOT SPOT FIX!!

They are not man made concrete pavers and should not be treated the same.

The sandstone should be fixed to an even mortar bed and then each piece of stone back buttered for a solid fix…

This will help illuminate possibilities of staining from moisture and mortar.

Natural stones like sandstone are not as dense as concrete pavers and are full of microscopic capillaries. These capillaries can draw up moisture from mortar through to the face of the stone. The moisture dries out to leave a deposit of mortar residue and minerals within the pores of the stone.Img3701 Sealing too soon after spot fixing can sometimes highlight these issues and also slow down the transition of moisture, suspending the cement residues within the stone.

The introduction of moisture from rain can also further highlight these issues. This is because the moisture collects and dwells within the voids between the mortar spots underneath the stone. As it dries out and the moisture rises carrying more minerals from the sand and cement to the surface of the stone.

Most sealers used for outside use are breathable and allow microscopic transition of moisture, so any trapped moisture is still able to dry out should it become trapped beneath the stone. Sealing does not cause the issues associated with spot fixing nor should it be considered a method for covering up the stains should they occur.

If your stone pavers have been spot fixed, then we would suggest not sealing them for at least 3 months after installation. This should allow for any mortars to full harden and any released minerals to completely dissipate. Clean surfaces well using LTP Power Stripper and leave to dry for 24 hrs. Test the sealer on a small area before general application to make sure that the mortar spots are not highlighted and after a few days make the test area wet and allow it to dry out. If staining does not occur the rest of the surface can be sealed.

If your stone has been fixed correctly into a solid bed then we would suggest a drying time of two weeks before sealing. This should allow enough time for all mortars to fully dry. Solid fixing will not allow any rain water to sit beneath the pavers and dwell. Clean surfaces well using LTP Power Stripper and leave to dry for 24 hrs. Seal using an impregnating sealer and apply as many coats as necessary to completely saturate the stone.

When sealing using an impregnating sealer it is important to remember that the solution needs to fully absorb into the stone without drying on the surface and do not apply in direct sunlight. If sealer is still visible on the surface after 45 minutes saturation has been achieved and any excess should be toweled off. For best results allow at least 3 full dry days after treatment.

CLEANING SANDSTONES & LIMESTONE  WITH SPOT FIXING ISSUES

Use: LTP Power Stripper

Apply undiluted to the surface of the stone and agitate using a black emulsifying pad. Add a little water and agitate again. Leave the solution on the surface of the stone for 15 minutes and agitate again. Rinse well with water. Repeat until the stains are no longer visible. Leave to dry for a minimum of 24 hours before sealing. Before re-sealing the whole area test the sealer on a small area before general application to make sure that the mortar spots are not highlighted. Leave to dry and after a few days make the test area wet and allow it to dry out. If staining does not occur then the rest of the surface can be sealed.

CLEANING MORTAR STAINS FROM SANDSTONES AFTER POINTING

Use: LTP Grout Stain RemoverGrout_Residue_Remover_Pack2

Apply un-diluted onto the surface of the stone and agitate immediately using a black emulsifying pad to release the mortar stains from the surface of the stone. Using a sponge and water rinse well immediately after use and change rinsing water after every 5 sq/m.

MOULD, MILDEW AND BLACK SPOT

Use: LTP Mouldex

Spray LTP  Mouldex onto the surface of the stone and leave for 1 hour. Using a black emulsifying pad agitate the surface and rinse well with plenty of water. Repeat until all organic matter has been removed. Re-seal surfaces once thoroughly dry.

Natural Stone Surfaces – Traditional and Ageing Method

Cleaning, Sealing and Maintaining Stone Surfaces – Part Two

Natural stone has been used on floors and walls for centuries. As with all natural materials, it does need a certain level of care.

This is the second in a 16 part series of posts that will offer a comprehensive guide to cleaning, sealing and maintaining all types of stone, porcelain, quarry, terracotta and glazed ceramic tiles and surfaces. This post explains the LTP three-step approach to cleaning, protecting and maintaining natural stone surfaces where a traditional or aged appearance is required. Using traditional oil and wax based sealers will greatly enhance the appearance of reclaimed flagstones, rough cut, honed and tumbled natural stone. If desired it can also provide stone surfaces with an instantly aged appearance. Traditional sealers will give natural stone a softer natural look. The following guide will explain the process and help keep your surfaces maintained and in good condition for many years.

Natural Stone Surfaces – Traditional & Ageing Method

The following instructions are appropriate for reclaimed flagstones, rough cut, honed and tumbled natural stone.

Step one: Initial cleaning

Before sealing natural stone must be thoroughly cleaned to make sure that sealing of the surface can be achieved effectively. This is true of newly installed surfaces, as well as existing, due to the contamination that can occur during fitting. Old layers of sealer, residues from after care products and deposits must be removed from the surface and pores of the tiles. Equipment recommended for this step is a bucket, mop, scrubber or scrubber dryer machine.

Cleaning newly installed reclaimed flagstones, rough cut, honed and tumbled stone surfaces

  1. Dilute LTP Grimex 1:5 with water.
  2. Apply solution to the surface with a mop or sponge. Turn off under floor heating.
  3. Agitate with a nylon pad or scrubbing-brush.
  4. Rinse well with clean water.
  5. Allow the surface to dry (preferably for 24 hours).

CLEANING NEWLY INSTALLED RECLAIMED FLAGSTONES, ROUGH CUT, HONED AND TUMBLED STONE SURFACES

Refurbishing used and heavily soiled stone surfaces

  1. Before sealing the surface must be thoroughly cleaned. Old layers of sealer, residues from after care products and deposits must be removed from the surface and pores of the tiles.
  2. Depending upon the levels of old wax and dirt, first remove old wax layers with LTP Solvex.
  3. Dilute LTP Grimex 1:5 with water and apply to the surface with a sponge.
  4. Agitate the surface with a nylon pad or scrubbing-brush and leave for a further 5 minutes (use scrubber machines on harder stone surfaces if required).
  5. Continue to scrub while adding clean water. Remove residues from the surface using a cloth or scrubber dryer machine.
  6. Rinse thoroughly with clean fresh water to remove all remaining residues.
  7. Allow the surface to dry for a minimum of 24 hours before applying the protective seal.

For the removal of other types of dirt refer to the list below. If you are unsure please call our helpline for advice.

  • Care product residues, oil, grease and dirt – use LTP Grimex or LTP Power Stripper.
  • Wax and acrylic layers, tar, paint, bitumen residues – LTP Solvex and then LTP Grimex.
  • Deeply engrained oil stains – LTP Spot Stain Remover and LTP Fullers Earth.

Step two: Protect your natural stone surface from stains

To protect reclaimed flagstones, rough cut, honed and tumbled natural stone surfaces and help prevent staining LTP recommends the application of LTP Stone Oil or LTP Stone Oil Antique. Surfaces should then be finished with an appropriate wax. Your choice of product will depend upon whether a traditional or aged appearance is desired.

The equipment you will need for this task: bucket, sponge, grout float, sponge, paint brush, soft cloth.

Traditional method

LTP Stone Oil and LTP Clear Wax: Will help to protect against water, oil, grease, dirt, grime and aid maintenance.

  1. Apply evenly with paint brush or soft cloth. Turn off under floor heating.
  2. Fully saturate the stone with sealer. Remove any excess sealer on the surface after 1 hour.
  3. Grout the joints and clean off any excess grout from the surface within 12 hours.
  4. Allow the surface to dry and dust off any remaining cement residues.
  5. Finish with a good coat of wax. Buff well with a soft brush or machine.

Protect your natural stone surface from stains - Traditional method

Ageing the appearance (internal surfaces only)

LTP Stone Oil Antique applied after a coat of LTP Stone Oil and after grouting will deepen the colour of the stone and joints. This will give an aged appearance. The number of coats applied determine the depth of colour. Finish by polishing with LTP Antique Wax or LTP Clear Wax. To establish the correct number of coats for the desired finish, test this process on a spare piece of stone before proceeding.

  • LTP Wax is film forming so should not be used externally or used on surfaces that are damp or have no damp proof course.
  • LTP Stone Oil and LTP Stone Oil Antique are suitable for internal and external use.
  • If surfaces are properly maintained we recommend touching up the protective treatment every 3-4 years.

NB. Always test the product on an inconspicuous area. Wet or non absorbent surfaces cannot be treated. LTP Stone Oil and LTP Stone Oil Antique are impregnators which need to fully absorb. Do not allow the product to dry on the surface. Carefully buff with a soft cloth or machine to remove any excess. Unabsorbed sealer if left to dry on the surface should be rubbed over with a little white spirit.

Step three: Maintaining your reclaimed flagstones, rough cut, honed and tumbled stone surfaces

Using the correct maintenance product will increase the life of your floor seal, provide more protection against staining and make sure your floor looks great. Common household cleaning products often contain harsh substances that can breakdown sealing products applied to stone. For this reason LTP recommends using LTP Waxwash on floors sealed with LTP Stone Oil and LTP Stone Oil Antique and finished with wax.

Regular maintenance on reclaimed flagstones, rough cut, honed and tumbled stone surfaces

  1. Protect from water for 24 hours and do not wash newly sealed surfaces for 3 days.
  2. Add one capful of product per litre of water in a bucket.
  3. Mop surface with the solution. Do not rinse.
  4. Allow to dry. Do not walk on the surface during drying time – 20 minutes.

REGULAR MAINTENANCE ON RECLAIMED FLAGSTONES, ROUGH CUT, HONED AND TUMBLED STONE SURFACES

A one litre LTP Waxwash will wash a 20 sq.m floor 40 times.

Should you use a professional floor restoration company?

The application techniques described above are achievable by a competent DIY enthusiast using the products as described. However, natural stone products are often expensive and by nature each stone has its own characteristics. We often find that many of our customers prefer to use the experience and skills of a professional stone restoration and cleaning company to make sure that their project finished to the highest standard.

LTP is pleased to be associated with the following companies that specialise in natural stone restoration and cleaning:

PLEASE NOTE: Always follow the detailed instructions on the product labels. Protect stone surfaces from contact with acidic substances. Do not use abrasive materials on honed or polished stones.

  1. Dilute LTP Grimex 1:10 with water.
  2. Apply solution to the surface with a mop or sponge. Under floor heating must be off.
  3. Agitate to release the residual dirt and grime from the surface.
  4. Do not use acidic cleaners, such as LTP Grout Stain Remover.
  5. Allow the surface to dry (preferably for 24 hours).

Cleaning natural stone with LTP Grimex

Refurbishing used and heavily soiled stone surfaces

  • Before sealing the stone must be thoroughly cleaned. Old layers of sealer, residues from aftercare products and deposits must be removed from the surface and pores of the stone. Film forming layers of sealer (such as boiled linseed oil) should be removed with LTP Solvex before washing with LTP Grimex.
  • Depending upon the levels of dirt, dilute LTP Grimex 1:3 with water. Apply with a sponge or cloth and leave to sit on the surface of the tiles for 5-10 minutes.
  • Agitate the surface with a nylon pad or scrubbing-brush and leave for a further 5 minutes (scrubber machines can be used).
  • Continue to scrub while adding clean water. Remove residues from the surface using a cloth or scrubber dryer machine.
  • Rinse thoroughly with clean fresh water to remove all remaining residues.
  • Allow the surface to dry for a minimum of 24 hours before applying the protective seal.
  • For the removal of other types of dirt: Do not use acid based cleaners on limestone or marble. If you are unsure please call our helpline on +44 (0) 01823 666213 for advice.

Step two: Protect your natural stone surface from stains

To protect stone surfaces and help prevent staining natural stone should be sealed. LTP recommends applying LTP Mattstone for a natural (invisible finish) or LTP Colour Intensifier & Stainblock for an enhanced appearance. LTP Colour Intensifier & Stainblock deepens the colour and enhances the appearance of the stone surface.

Sealing prepared natural stone surfaces

  1. Surfaces must be clean and dry. Ensure under floor heating is off.
  2. Apply the product to the surface evenly using a sponge, brush or soft cloth.
  3. Redistribute to remove excess product and avoid pooling on the surface.
  4. Allow to dry. Do not walk on the surface for at least one hour.
  5. Protect from water for 24 hours and do not wash surfaces for at least 3 days.

Sealing natural stone with LTP Mattstone, LTP Mattstone H20 or LTP Colour Intensifier.

  • LTP Mattstone H20, LTP Mattstone and LTP Colour Intensifier will make the surface water and oil repellent.
  • Prevents stains, aids cleaning and simplifies the removal of surface stains.
  • Provides an invisible barrier of protection that will not greatly alter the surface character.
  • There are no health concerns once the product has properly cured.
  • LTP Mattstone H20, LTP Mattstone and LTP Colour Intensifier are micro porous and so can be used on surfaces that have no damp proof course.
  • Suitable for internal and external use.
  • If surfaces are properly maintained we recommend touching up the protective treatment every 3-4 years.

NB. Always test the product on an inconspicuous area. Wet or non absorbent surfaces cannot be treated. LTP Mattstone H20, LTP Mattstone and Colour Intensifier are impregnating sealers which need to fully absorb. Do not allow the product to dry on the surface. Carefully buff with a soft cloth or machine to remove any excess. Remove unabsorbed impregnating sealer, if left to dry on the surface, by rubbing over with a little more sealer. Some stones may be darker after application. Acidic substances, if left on the surface, may damage stone.

Step three: Maintaining your natural stone wall or floor

Using the correct maintenance product will increase the life of your floor seal, provide additional protection against staining and make sure your floor looks great. Common household cleaning products often contain harsh substances that can breakdown sealing products applied to stone. For this reason LTP recommends using LTP Waxwash on floors and LTP Stonewash for surfaces.

LTP Waxwash (for floors): Formulated for use on unglazed tiles such as travertine, stone, limestone, slate, terracotta and quarry. Ideal for washing floors sealed with LTP Mattstone H20, LTP Mattstone or LTP Colour Intensifier. Use routinely in place of normal detergent.

LTP Stonewash (for walls): This gentle surface cleaner is formulated for use on limestone, marble, granite, slate and polished porcelain. Will clean without breaking down and removing protective seals.

Regular maintenance on stone floors

  1. Add one cap full of product per litre of water in a bucket.
  2. Wipe surface with the solution. Do not rinse.
  3. Allow to dry. Do not walk on the surface during drying time – 20 minutes.

Maintaining natural stone with LTP Waxwash

A one litre LTP Waxwash will wash a 20 sq.m floor 40 times.

PLEASE NOTE: Always follow the detailed instructions on the product labels. Protect stone surfaces from contact with acidic substances. Do not use abrasive materials on honed or polished stones. Avoid using normal detergents or strong bleach cleaners on sealed surfaces as they will gradually remove the protective seal.

Basalt stone – Dealing with white patches

Basalt stone case study

A Basalt tiled floor showing white patches of discolouration.Issues with white patches appearing after sealing Basalt tiles

We were recently contacted by a customer who was having problems with white patches appearing on their newly installed Basalt tiles. This is a common problem, so we thought we should share why and how this issue sometimes occurs. The pictures in this post supplied by a customer show a charcoal grey Basalt tile that has been sealed with a reputable stone tile sealing product.

The customer explained:

“The dark tile is where a colour enhancing tile sealing product was used by the tiler to test to see if it might remove the lighter patches but as you can see this has only enhanced them; the tiled shelf has not had the sealer applied and displays the similar distinct lighter patches; one of the tiles has very distinct striations where it appears the saw marks have not been completely ground out; the floor looks dusty but it is not.”

Basalt floor tiles with white discolouration patches Basalt floor tiles showing white discolouration

How and why discolouration can occur in Basalt stone surfaces and tile installations.

Understanding Basalt stone

In geological terms, basalt is quite a young volcanic stone. When volcanic eruptions take place and volcanic material is formed, excess argon gas can get trapped within lava flows. This argon is held primarily in lattice vacancy defects within the minerals that form to make basalt. These pockets of argon gas are sometimes released when the stone is quarried, cut into blocks, sawn into slabs and then honed on the surface to make it ready for use as a cladding and tiling material. This ensures that Basalt has an extensive capillary make up.

What can cause discolouration and hazing?

Moisture and polymer from adhesive used to complete installations can be drawn up through the natural capillaries within the stone. This can release minerals and salts from within the stone, causing a light bloom or haze from within. In this instance, there is no chemical cure or cleaner that will remove the stains from the stone.

It is also common to see grout floated across the surface (in order to complete grouting between the tiles). This will often fill some of the open capillaries contributing towards a mottled and uneven appearance. In this case, grout on the surface can be removed using a chemical cleaner but grout that has settled within the open pores is likely to be impossible to remove. No amount of scrubbing or cleaning will make any difference. In both cases any additional sealing would only further highlight the marks left by the adhesive and the grout.

Removing the discolouration and hazing

There are two alternative approaches to addressing this issue:

  • For surface grout stains attempt to clean back the surface of the tile with a specialist intensive cleaner and reseal.
  • Remove and replace the tiles.

Intensively clean and reseal

Please note that the following advice should be completed on a small area (single tile) to establish if it will result in a more satisfactory finish:

Clean thoroughly with LTP Grout Stain Remover. This will effectively etch the surface of the stone and should dry to leave it more even in appearance. Note that this treatment will change the texture of the stone making it feel a little rougher. Rinse thoroughly and leave to dry. Re-seal using LTP Mattstone H20 applying as many coats as necessary to achieve saturation. Do not let the solution dry on the surface. Remove any visible excess from the surface within 20 minutes.2.

Remove and replace

Unfortunately, where staining has been caused by moisture drawn up through the stone or grout cannot be removed the only other option would be to remove and replace the tiles.

How to avoid issues when installing Basalt stone

When the new stone is fitted, make sure that the underside of the stone tile is sealed before laying. Use a good quality water-based sealer such as LTP Mattstone H20. After laying and before grouting, seal the surface of the stone with as many coats as necessary to reach saturation point. Before completing the general application of grout, test a small area for grout ingress. Grout ingress is caused when grout material is forced into the surface of the stone during the grouting process and can be difficult to remove. If grout material is absorbed, then a further coat of sealer may be required before proceeding.

Once all residual grout has been removed and surfaces are clean and dry, finish with a further coat of sealer making sure to cover the grout joints as well.

Eco-friendly sealer – LTP Mattstone H20

Eco-friendly water-based sealer for natural stone – LTP Mattstone H20

LTP Mattstone H20 – Eco friendly water-based sealerFollowing 18 months of research and development, LTP launched its flagship eco-friendly water-based impregnating sealer LTP Mattstone H20 in the spring of 2011.

The LTP team were keen to deliver a sustainable eco-friendly product solution for sealing natural stone that matched increasing customer awareness of environmental impact.

Tightening restrictions on the use of Volatile Organic Compounds (VOCs) has ensured that water-based sealing products for natural stone are becoming more widely available in the market place. As demand has risen so water-based technology has improved. It was vital that any LTP solution created needed to set the standard for such technology and deliver results that matched existing products options. So, inspite of the advances in technology, the Research & Development Department at LTP embarked on a program to make sure that the formulation chosen for the new Mattstone H20 impregnating sealer provided the best possible results at a realistic price.

“Our chemists looked at all the raw materials available, these were mixed to create various formulations. We then began testing these against various criteria such as stain resistance, longevity, and water beading on all types of natural stone.  Interestingly enough it was the 20th formulation we tested that finally hit the mark, hence the appropriate name for our eco-friendly water-based impregnating sealer” comments technical director Mark Atkins.

LTP Mattstone H20 is keenly priced when compared with similar water-based impregnating sealers on the market.

Mark Atkins continues, “You can find cheaper water-based impregnating sealers, but be careful, these tend to be hydrophobic only. It is important to make sure that the sealer you choose is going to protect your natural stone surface from oil based stains as well as water, that’s the tricky bit from the chemistry aspect. We are delighted with the performance of LTP Mattstone H20, which we feel has resistance properties equal to our traditional spirit based Mattstone product.”

Eco friendly and low odour

Apart from the obvious benefit to the environment, the other important selling point is that unlike the spirit based alternatives, LTP Mattstone H20 is essentially odour free on application. This puts it at a great advantage especially in circumstances when a surface has to be sealed and made suitable for immediate use, all in a short time scale.

LTP Mattstone H20 can be used internally and externally and is suitable for all types of natural and artificial stone.

Some care should be taken during application as the procedure differs slightly from traditional LTP Mattstone application. With LTP Mattstone H20, as indeed with most water-based impregnating sealers it is necessary to apply wet in wet. Apply Mattstone H20 generously and evenly with a lint free cloth, or similar and make sure even distribution by wiping over several times. After 15 minutes any excess sealer should be removed with an absorbent cloth.

Provided the finished surface is regularly maintained with a suitable maintenance product, in this case LTP Waxwash, LTP Mattstone H20 should provide the end-user with excellent protection for their natural stone surface.

LTP Mattstone H20 is manufactured in 1 litre and 5 litre containers and is available immediately from all LTP stockists and Tile Giant Stores, details can be found on the LTP website: www.ltp-online.co.uk

Limestone: White or grey deposits on black paving?

Why do mineral stains show up so prolifically on black limestone pavers laid outside?

We are often contacted about mineral stains on black limestone paving. This is often perceived as an issue with the supplied paving stones, laying process or sealing method. Below we explained how a combination of naturally occurring elements can cause this phenomenon. It is in fact not uncommon and occurs with most types of limestone; however the appearance of mineral salt deposits on a black or darker coloured stone is more prevalent. This is why it is possible to notice some marks appearing even before sealing. As a naturally occurring chemical reaction it is often difficult to avoid. However, if fully understood and considered when laying and protecting black limestone this potential issue can be effectively managed.

What causes white and grey mineral stains on black limestone pavers?

When rain water trickles through mortar it can dissolve and transport soluble alkaline compounds. Rain water percolating through sand-cement mortar screed, toppings and bedding under limestone paving can become moderately alkaline. As this rainwater evaporates, its alkalinity increases until the solution becomes saturated. This solution can then travel via natural capillaries within the limestone to the surface where it starts to deposit solids such as white and grey encrustations of calcium carbonate commonly known as lime plumes and efflorescence as seen in the image of the black limestone pavers shown below.

Mineral deposit stains on black limstone

Halo stains and bands of mineral deposits

Trace amounts of sodium and potassium oxides within limestone can also be activated by rain water. Even where rain is mildly acidic, the solutions of these salts in rainwater will gradually become alkaline. Surface wetting and evaporation can produce recurrent patches and bands of dampness known as accumulation zones (rainwater pooling on the surface where it cannot run off). Evaporation concentrates the alkaline solutions until they become saturated at the outer limits or edge of accumulation zones. Further evaporation then causes precipitation, crystallisation and immobilisation of the salts at the surface and in pores immediately below the surface. The resulting bands of distinct pigmentation are halo stains as seen in the image of limestone pavers shown below.

Mineral deposits causing a banding effect

Reducing the impact

Protect your paving with the correct sealing product

Sealers used to enhance the appearance and prevent limestone pavers staining from organic matter outside should be breathable. LTP Mattstone, LTP Stone Oil and LTP Colour Intensifier are examples of breathable sealers suitable for external use. As well as protecting the stone from staining, breathable sealers will allow the microscopic transition of moisture assisting any trapped moisture to escape through the stone from the mortar and sub surfaces. However, moisture permeating through the stone and sealer to the surface can still dry to leave a calciferous deposit.

How do I remove mineral salt stains from the surface of limestone

Wash the surface with a mild solution of acid. This will help disperse the mineral salt deposits from the surface. The downside of this approach is that the acid solution can have a slight etching effect on the surface of the stone causing it to dry much lighter.

LTP Grout Stain Remover is a product suitable for this task. Dilute 1 part LTP Grout Stain remover in 4 parts warm water and apply to the surface of the stone. Agitate using an emulsifying pad or similar abrasive and then rinse thoroughly with plenty of clean water. Repeat this process to remove all mineral deposits.

Ensure you protect your paving by resealing

Once the surface is thoroughly dry and  mineral salt deposits on the surface are greatly reduced, re-seal the stone with an appropriate limestone sealer. LTP Mattstone is our most popular and highly effective natural stone sealing solution and is suitable for external use. However, many of our customers have successfully used LTP Stone Oil after acid washing their stone as it helps to re-enhance and deepen the colour.

Apply LTP Mattstone or Stone Oil impregnating sealer to the surface of the stone using a paint brush. Allow it to absorb into the stone and then remove any visible excess from the surface after 45 minutes using an absorbent dry towel. The aim is to completely saturate the stone with as many coats of sealer as necessary, but do not allow the sealer to dry and leave a film on the surface. Do not apply in direct sunlight.

Please note that this information is offered as general guidance only and without guarantee. Your specific circumstances may need an alternative approach. In case of doubt, any process should be tried out in an inconspicuous area before general application.

Renovating natural stone floors and wall tiles

Renovating tiled floorsWhen is renovating stone floors and walls the solution?

Renovating floors and walls is a task that is difficult to avoid if you own a natural stone surface for a long period. Over time natural and artificial stone walls and floor tiles can become ingrained with dirt, grime and stains of all types. Use of the correct protective sealer and regular use of an appropriate routine maintenance product will minimise the speed at which this takes place. However over time and where exposed to extreme levels of traffic, stone flooring in particular, can become dull, dirty and worn looking, even after a routine cleaning. When this happens renovating stone floors or walls by removing tile sealers and re sealing the surface, can be the most effective approach.

If natural stone surfaces have not been sealed properly then dirt and grime can very quickly become ingrained in the surface. If stains such as coffee, red wine, grease and fat are left on the surface for long periods these can prove very difficult to remove from the surface of stone. It is important to remember that even if your natural stone has been protected by a sealing product. This will make the surface stain and water-resistant not bullet proof. Moped up spills immediately to avoid liquids such as red wine, that contain acid etching through the surface.

Again in this situation renovation of stone floors and walls maybe the only effective solution.

Remove excess sealer from stone flooring and walls

Renovating natural stone floors and wall tiles can also be required in order to remove excess sealer due to over application when installing a new stone floor. The application process of a tile sealer to a newly installed floor should include steps to any remove excess sealer before it dries. Failure to address this step will often lead to unsightly discolouration of the surface. Often this does not need the surface seal be fully removed. Please contact our Technical Helpline for help on how to remove excess sealer? When removing tile sealers we highly recommend that you select an effective commercial intensive cleaning product to suit your natural stone floor or wall.

Removing Boiled Linseed Oil

Another common renovation situation is the removal of boiled linseed oil. Boiled linseed oil oxidises over time and provides a fantastic seal to the tiles. But during the oxidisation process the boiled linseed oil often changes colour and becomes a brown tinge or sometimes an orangey hue when too highly diluted with spirit. The result is a dirty looking shadow over your floor especially where the oil had penetrated really deeply. Removing boiled linseed oil can prove to be particularly challenging so we would recommend that you contact our Technical Helpline for free advice and help when dealing with boiled linseed oil.

Selecting the correct approach to renovating a stone surface

The method of renovating stone wall or floor surfaces and removing tile sealers will depend upon the type of surface material and the protective sealing product originally used to protect the surface. Offering general advice without understanding specific circumstances is often difficult although we have outlined some common circumstances below.

If you are uncertain about the type or make of sealing product used to originally protect your surface please contact our Technical Helpline on +44 (0) 1823 666213 or email us at info@ltp-online.co.uk

Common renovation situations

Renovating floor tiles sealed with Boiled Linseed Oil or Beeswax

  • 

Step 1: Use LTP Power Stripper when removing boiled linseed oil or wax from floor tiles.
  • 
Step 2: Apply one coat of LTP Stone Oil, following instructions on the container.
  • Step 3: Allow 24 hours for LTP Stone Oil to cure before finishing floor tiles with LTP Waxwash.

Renovating walls and floors sealed with a film forming surface tile sealer

Visit our blog for an explanation of the difference between surface and impregnating sealers.

This includes removing tile sealers such as LTP Ironwax SatinLTP Ironwax Gloss 
or LTP Glaze Protector or other polyurethane sealers and varnishes.

Renovating walls and floors sealed with an impregnating tile sealer

This includes removing tile sealers such as LTP MattstoneLTP Colour Intensifier & Stainblock or LTP MPG Sealer.

One last tip: Once you have renovated your floor clean and maintain it regularly with an appropriate maintenance product. This will make sure that the surface retains the desired look for longer and will extent the life of your surface seal. LTP offer two highly effective maintenance products in LTP Waxwash and LTP Floorshine.
