This impregnating liquid is already diluted to a ready-to-use product and can be applied by dipping, using a high-pressure sprayer, or with a brush. We recommend applying 2 to 3 coats on planed wood. For finely sawn wood, 2 coats are sufficient. Drying takes about 48 hours, depending on the weather. Keep in mind that the liquid can cause stains. On non-porous surfaces like glass or steel, it doesn't adhere and can be rinsed off with water.
