For new joinery or preservative treating wood before painting then Sovereigns range of preventative treatments are ideal. Our solvent based preservatives are available in a range of colours as well as clear. These fungicide and insecticide preventative treatments keep timber safe from wood boring insects such as woodworm and both wet and dry rot. Traditional boron rods for implanting into predrilled holes in timber are still available. Our dry rot paint can be used on both masonry and timber e.g. the back of skirting and architrave to prevent the spread of the dry rot fungus.
