Sealing Natural Stone Tiled Floors

Natural stone can be affected by staining, moisture and unsuitable cleaning products. The right protective treatment depends on the stone, its surface finish, location and how the floor is used.

Why seal natural stone floors?

Many natural stones have pores that can absorb spills. A suitable sealer may improve stain resistance and make routine maintenance easier; it does not make a floor stain-proof or remove the need for careful cleaning.

Impregnating and surface sealers

An impregnating treatment is designed to penetrate the stone and help reduce absorption while leaving much of its natural appearance. Some formulas subtly enhance colour. A topical coating forms a layer over the surface and may change sheen or wear behaviour. Selecting between these approaches involves the material's moisture conditions, appearance and maintenance requirements.

Always establish whether the stone is already sealed or coated before applying another product. Wrong-product combinations can cause poor adhesion or patchiness.

Care after sealing

Follow the manufacturer's curing instructions. Use a cleaner suitable for the specific stone and sealer, avoid aggressive or acidic products on sensitive stone, and review protection if the surface begins absorbing liquids more easily.
