How do I clean my external paving?

Featured

Patio’s can give that refined and uniform look to a garden area, a clean cut from grass to stone, and when newly laid they look fantastic.

If you had them laid before the winter months however they probably won’t look the same now as they once did. With the amount of rain that we have had over the last few months, the probability is that you will have some form of green growth on the tiles.

This green growth is a mix of Algae, moss and lichen which builds up on the tiles, normally more common in areas of higher rainfall, as this is the perfect place for algae to grow, high rainfall and with areas for the algae to cling to.

However this isn’t the end of your patio, as this can be easily fixed with the correct tools.

Cleaning Patios With LTP Mouldex

Firstly you will want to brush the stone with a stiff bristle deck brush to remove any leaves, dirt or debris from the surface of the stone.

Making sure the area is now free of loose debris, pour LTP Mouldex direct on to the stone and spread out over the area with a brush or sponge. (Garden sprayers can be used)

Leave for a minimum of one hour, then add a little water and agitate with a emulsifying pad or stiff deck brush to help loosen algae, dirt and grime.

After a minimum of 1 hour, agitate with emulsifying pad.

After a minimum of 1 hour, agitate with emulsifying pad.

Rinse thoroughly with water. Garden hoses and jet washes can be used. Be careful though as jet washes force water at the surface at high pressures and can cause damage to some stones.
Some stubborn stains and black spot will require longer treatment, in which case apply and leave overnight.

Rinse well with plenty of water

How to achieve different finishes on Natural Stone

Different finishes on natural stone

SEALING:                       LTP MATTSTONE                    500ml, 1 & 5ltr containers

LTP MATTSTONE (Natural Finish): Apply evenly to the surface using an applicator LTP-Mattstone5L,1L_500ml_Grp_Webpad or soft cloth.  Leave the sealer to absorb into the stone for 30 minutes.  Work into and then buff off any excess using a micro-fibre cloth. Apply further coats using the same method until the stone is fully saturated. Leave to cure overnight.  This should be done before grouting. Finish by applying a further coat of sealer making sure to cover the joints as well.

Buff off any excess sealer between coats…allow to dry for 24 hours before allowing heavy traffic.

Patio & Driveway Surfaces – Cleaning, Sealing & Maintenance

Natural Stone Surfaces – External Application

Cleaning, Sealing and Maintaining Natural Stone – Part Three

Natural stone has been used as an external surface covering for paths, driveways, patios, court yards, terraces, porch areas,verandas, loggia and sun decks for centuries. As with all natural materials, it does need a certain level of care.

This is the third 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 used in external applications such as paths, driveways, patios, court yards, terraces, porch areas,verandas, loggia and sun decks. Natural riven or rough cut stones are often used outside because they are naturally slip resistant. Normally thicker than internally fixed stone they are more robust and harder wearing. The following guide will explain the process and help keep your surfaces maintained and in good condition for many years.

Natural Stone Surfaces – External Application

The following instructions are for sawn and honed, riven or rough cut finish: sandstone, slate, granite, quartzite and rough cut and riven limestone.

Step one: Initial cleaning

Before sealing, clean natural stone thoroughly to make sure that the surface is sealed  effectively. This is true of newly installed surfaces, as well as existing, due to the contamination that can occur during fitting. On existing surfaces such as patios, driveways, paths and terraces remove old layers of sealer, dirt residues and light deposits of organic matter and algae  from the surface and pores of the stone. For newly installed surfaces cleaning should remove all grout and cement residue and any general dirt or grime that has built up while fitting. Bucket, mop, sponge, scrubbing-brush or scrubber dryer machine if available.

Newly installed surfaces

Before grouting and once surfaces are clean and dry: Apply one coat of LTP Colour Intensifier & Stainblock before grouting. This treatment will help with the removal of residual cement and grout from the surface of the stone paths, driveways, patios, court yards, terraces, porch areas, verandas, loggia and sun decksLTP recommends using LTP Grout Stain Remover to clean and remove residual grout and mortar from the textured riven surface of natural stone driveways, patios, court yards, paths, stone terraces,verandas, porch areas and sun decks once they have been laid.

Please note: Do not use LTP Grout Stain Remover on honed and smooth limestone. 
This product is only suitable for use on riven limestone.

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

  1. Dilute LTP Grout Stain Remover 1:2 with water. On rough cut limestone dilute 1:6
  2. Apply solution to the surface with a stiff brush and agitate immediately.
  3. Leave for 5 minutes and agitate again. Rinse well with water.
  4. Rinse well with plenty of clean water.
  5. Allow the surface to dry.

Step One Cleaning External Stone Surfaces

Refurbishing used and heavily soiled stone surfaces

  1. Before sealing the clean stone thoroughly. 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.
  2. Dilute LTP Grimex 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.
  3. Agitate the surface with a stiff deck brush every 5-10 minutes (scrubber machines can be used).
  4. Continue to scrub while adding clean water. Remove residues from the surface with water or scrubber machine.
  5. Rinse thoroughly with clean fresh water to remove all remaining residues. Use a power washer if necessary.
  6. Allow the surface a minimum of 3 dry and damp free days before applying the protective seal.
  7. For the removal of other types of dirt refer to the table below.
  8. Do not allow the sealer to dry on the surface. Carefully buff with a soft cloth or machine to remove any excess. Complete this within 1 hour of application.

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

Step two: Protect your natural stone surface from stains

To protects sawn and honed, riven or rough cut finish: sandstone, slate, granite, quartzite and rough cut and riven limestone surfaces and help prevent staining LTP recommends the application of LTP Colour Intensifier & Stainblock.

The equipment you will need for this task: bucket, applicator, brush, cloth.

Application of LTP Colour Intensifier Stainblock: Enhanced natural finish protects against water, oil, grease, dirt, grime, organic matter and aids maintenance

  1. Clean surfaces and ensure they are dry.
  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 3 hours.
  5. Protect from damp and wet conditions for at least 3 days.

Step 2: Sealing external stone surfaces

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

Using the correct maintenance product will increase the life of your stone seal, provide more protection against staining and make sure your path, driveway, patio, court-yard, terrace, porch area, veranda, loggia or sun deck 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 Grimex on external surfaces sealed with LTP Colour Intensifier & Stainblock. LTP Grimex will remove surface dirt when required (normally every 3-6 months).

Regular maintenance on sawn and honed, riven or rough cut finish: sandstone, slate, granite, quartzite and rough cut and riven limestone

  1. Dilute LTP Grimex 1:3 with water.
  2. Apply the solution to the surface and agitate.
  3. Leave for 10 minutes before agitating again and then rinse with water.
  4. Leave to dry for 24 hours and then if necessary re-apply a light coat of sealer.
  5. Protect from damp and wet conditions for a minimum of 3 days.

Step 3: Maintaining External Stone Surface.

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 is completed to the highest standard. LTP is pleased to associate 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. Avoid using normal detergents or strong bleach cleaners on sealed surfaces as they will gradually remove the protective seal.

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.

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 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.

Further information on traditional and ageing method protective seal treatments

  • LTP Stone Oil, LTP Stone Oil Antique and LTP Clear Wax will render the surface water and oil repellent.
  • These products help to prevent staining, aid cleaning and simplify the removal of surface stains.
  • LTP Stone Oil and LTP Stone Oil Antique will alter the natural character.
  • LTP Clear or LTP Antique Wax will give an easily maintainable hard-wearing satin sheen.
  • There are no health concerns once these products have properly cured.
  • 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.
