Processing instructions Apply one to two coats with hand trowel on prepared substrate. Allow the putty layer to dry thoroughly. After successful intermediate sanding, the next layer of putty can be applied. Attention: do not add more material than can be applied properly in 5 minutes!
Particular instructions Exotic woods such as macassar or knotty pine with an extremely high resin content must be prime with suitable isolating primers (e.g. PU Isolating primer DG 4720-0001). The lowest amounts of peroxide residue in the dry putty layer could trigger a chemical reaction with certain PU lacquers, creating a yellow-brown discolouration. Therefore, only use peroxide-containing lacquer systems to coat the putty layer!
