H4 Wood & Stone Water Repellent

Properties

Owatrol H4 WOOD & STONE is a colourless, waterproof protection for wood, stone & masonry.

H4 can also be used as an additive into any Exterior Masonry Paint to waterproof damp walls etc.       (NOTE: If you are using Owatrol EB in the first coat - add H4 only to the top coat)

Silicone free and incorporating the new technology PARAFLUOROSILANE (pfs), H4 WOOD & STONE protects wood, stone & render etc from environmental attack.

Hydrophobic and therefore water repellent, H4 WOOD & STONE allows wood to grey naturally while protecting against water ingress, mould, pollution etc. Stabilises the woods’ lignin, H4 WOOD & STONE increases 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.
