HG Natural Stone Impregnating Protector (Product 32) is used to impregnate porous marble, travertine, terrazzo, granito, slate, sandstone, limestone and other natural stone floors and walls to protect against stains and stubborn marks.
For terracotta tiles, brick, quarry tiles, victorian tiles, flagstones, un-glazed (porcelain or ceramic) tiles we recommend HG Impregnating Protector Sealer (HGP13) which has larger molecules and it is therefore slightly thicker making it more suitable for more porous materials.
To check the porosity of a surface to see if treatment is required use a tablespoon of water. If after 5-10 minutes none of the water has been absorbed into the surface the surface is sealed.
HG Natural Stone Impregnating Protector penetrates deep into the surface and completely seals off small pores. Larger pores are made smaller meaning liquid molecules can no longer be absorbed preventing the formation of stains and dirt. However, any dampness in the floor can still evaporate. HG Natural Stone Impregnating Protector still allows the stone to breathe. Does not change (or hardly changes) the original characteristics of the material. Leaves a matt finish enhances natural colours, does not contain silicone. It is suitable for inside and outside use.
Coverage: Highly porous natural stone: 10-20 m² per litre. Slightly porous and high gloss natural stone 20-50 m² per litre.
