Water-based acrylic resin primer — non-toxic, harmless to health and environmentally compatible. Suitable for interior surfaces made of concrete, cement, plaster bricks, wood or plastic (except PE, HDPE, PP, PTFE).
Which substrate is suitable?
Building materials such as concrete, cement, wood, render and similar materials — including old stock (e.g. listed buildings), provided it is continuous and load-bearing. The substrate must be dry, firm and free of loose parts, oil, grease, dust, mould, salt and old loose coatings.
How is BASIC B applied?
Supplied ready to use; thoroughly mix the entire container contents before use. Preferably applied with an airless sprayer (remove the filter beforehand, nozzle pressure max. 120 bar), alternatively with brush or roller (bristle length 8–14 mm). A second coat is possible once the surface is touch-dry after approx. 2 hours.
