H4 WOOD & STONE is a colourless, waterproof protection for wood and stone. Silicone free and incorporating the new technology PARAFLUOROSILANE (pfs), H4 WOOD & STONE protects wood and stone from environmental attack. Hydrophobic and therefore water repellent, H4 WOOD & STONE allows wood to naturally grey while protecting against water ingress, mould, pollution etc. Stabilising the woods’ lignin, H4 WOOD & STONE helps increase the service life of the wood. Ideal for stone, H4 WOOD & STONE seals and fixes even the most fragile surfaces helping to prevent the build-up of dirt, algae etc.
Completely colourless H4 WOOD & STONE has no effect on the colour or appearance of the surface being treated.
