Having been dormant over the summer months, most fireplaces need a little attention come the autumn. They are, after all, the focal point of a cosy night in and, at Christmas, a key feature for decorations and festivities.
In general, stone hearths and surrounds are robust and require little maintenance. Stone is, however, surprisingly porous and can be easily stained – and sometimes permanently discoloured – by soot, smoke, candle wax, wine and coffee. Unlike stone floors, newly installed fireplaces often aren’t sealed to protect them – but treatment of both old and new stonework is very easy, and will be well worth the effort.
Step 1 – cleaning
Whether your fireplace is old or brand new, it will benefit greatly from a thorough clean. Newly installed stone will have become dusty during fitting, and residue will need to be removed before the surface can be sealed. If you apply a sealer over residue, the dust and dirt will become sandwiched between the stone and the sealer; this will prevent the treatment from absorbing into the stone – and from doing its job – and will create a patchy finish.
For a thorough clean, we recommend LTP Stoneclean. It’s a fast-acting foaming aerosol solution, so it can be safely applied onto vertical surfaces without risk of run-off. Stoneclean can be used on polished and unpolished surfaces – and it removes dirt, soot, grime and any build-up of wax and aftercare product.
To apply the foam treatment, just point and spray in a sweeping action, 15-20cm from the surface. It will penetrate deep into the stone’s porosity in between 5-10 minutes. The surface should then be agitated using a white emulsifying pad and a little water, before being rinsed with a clean sponge and clean water; change the water regularly to avoid recontaminating the surface. A repeat treatment may be necessary if the stone is very stained.
Step 2 – sealing
To protect the fireplace from stains, apply LTP Stoneseal. Like the cleaner, it’s also an aerosol, so it’s quick and easy to apply. The treatment creates a colourless barrier – without altering the appearance of the stone – and protects against water, dirt, oil, grease, soot and limescale. As well as protecting the surface, LTP Stoneseal will also make cleaning easier. A little water can be dropped onto the surface 30 minutes after application, to test the protection. If it’s absorbed, a second or third coat can be applied to give maximum protection. The surface will be fully dry within 2-3 hours of the final application, and fully cured 3 days later.
On smooth, polished surfaces, any visible excess should be removed five minutes after application, with an absorbent cloth. The surface should be buffed with a soft lint-free cloth.
Step 3 – maintenance
To keep the newly treated surface clean, use a specialist treatment like LTP Stonecare. It will clean without damaging the sealer or the stone’s surface. Stonecare is applied in the same way as Stoneclean and Stoneseal – just spray 15-20cm from the surface, then wipe the stone with a clean cloth and leave to dry. Honed and polished surfaces should be buffed to finish.
During each stage of treatment, rooms should be well ventilated. For more advice, visit https://www.ltp-online.co.uk
