H4 Wood is a colourless, waterproof protection for wood which allows it to age naturally and turn grey without damage from water, pollution, moss and dirt. Perfect if you like the natural look of wood as it turns grey but are anxious to prevent damage such as splitting and cracking which will happen if wood is left untreated.

H4 Wood is hydrophobic and therefore water repellent, it is completely clear and will have no effect on the colour or appearance of the wood being treated. It is silicone free and helps to prevent environmental attack including from mould and water.
