Re-Sealing Natural Stone Tiles - When and How Often?

31 October

Natural stone tiles have been used on floors and walls for centuries and requires a cleaning, sealing, and maintenance regime to keep them in showroom condition. The following instructions are a guide to help ensure that your stone surfaces will remain protected and easy to clean for many years.

Your Adhesive

Let’s take a step back and look at the best tile adhesive to use for your installation project. We always recommend using a white rapid set flexible adhesive such as Kerakoll Biofast. Biofast is specially formulated for fixing natural stone tiles, your tiler will thank you for buying it as it’s made in part from microbeads of natural carrara stone making it smooth and easy to work with, particularly when installing heavy large format tiles such as Stonestore's impressive 900x600 format Dijon tumbled limestone.

Using Kerakoll Biofast rapid set adhesive will prevent a common installation problem of the surface of natural stone tiles developing patchy blotches caused by the use of grey slow set adhesive which can stain the surface as moisture is drawn from the underside of the tile to the surface of the tile by capillary action.

Cleaning Before Re-Sealing

All stone tiles are porous, therefore require re-sealing every 3-4 years. However, before re-sealing the old grimey sealer should be removed with an intensive cleaner such as LTP Power Stripper. The LTP Power Stripper will soften and lift the existing sealer and LTP Grimex should be used to remove surface residues. Using LTP Grimex after LTP Power Stripper will prevent impurities from being re-sealed into the pores of the tile, allowing those pores to fill with sealer, and for the sealer to work effectively.

Re-Sealing The Tiles

Sealing tiles will make the surface water and oil repellent, prevent stains, aids cleaning and simplifies the removal of surface stains.

Providing an invisible barrier of protection, we recommend LTP Matt Stone for honed and tumbled surfaces such as Stonestore’s Bancroft Limestone, and LTP Polished Stone & Porcelain Sealer for shiny polished natural stone such as our Italian classic Bianco Carrara.

Maintenance Of Stone Tiles

Sealing the tiles will make daily maintenance easier. As part of your cleaning routine use LTP Waxwash, a high-quality liquid soap suitable for all types of natural stone, including polished marble and tumbled limestone. LTP Waxwash is a gentle cleaner, containing a trace of linseed oil especially formulated to clean the most delicate surfaces and is ideal for use on travertine, limestone, sandstone, slate, marble, granite, porcelain, terracotta, terrazzo, concrete, quarry tiles and flagstones. It also has a fresh, clean fragrance.

To use, simply dilute 2 or 3 capfuls (5 capfuls on dirtier floors) in a bucket of warm water. Wash the floor and allow to dry. It does not require rinsing, although polished finishes will benefit from buffing with a dry, soft cloth.
