Bird Brand Superior Clear is both a wood preserver and a woodworm killer.  It is water based and dries clear, making it perfect for over coating with paints and primers.  Equally it can be left unfinished or used just to kill woodworm.

Superior Clear Wood Preserver contains 3 active ingredients that are designed to prevent and eradicate wood boring insects, mould, dry rot and wet rot.  Being water based the product still penetrates but is much more  pleasant to use and virtually odourless.

Superior Clear Wood Preserver & Woodworm Killer is also HSE approved and comes in a range of sizes from 500ml to 25 Litres.
