DIRECTIONS FOR USE

Mix before use! Remove all bark residues, old paint coats and debris before treatment. For the preservative to be deposited uniformly and evenly across the timber surface, treatment should take place at temperatures of +5°C to +30°C. Soaking time will depend on the timber’s moisture content. Wait until the first coat has soaked in completely (about 4-24 hours) before applying the next coat or spray. Once treated, outdoor timbers (use class 3) must be covered with a suitable coating.

Certified as effective under EN 46-1, EN 113, EN 73, EN 84 (prevention) and EN 330 (field testing).
