Bona R590 is a one-component silane based primer for priming and/ or sealing the residual moisture in cement screeds or concrete (up to 5% CM/ 90% RH) before installing a wooden floor.
It can also be used for the reinforcement of weak subfloor surfaces up to a certain level. Bona R590 is compatible with all Bona silane and polyurethane adhesives and as well for Bona levelling compounds. The water- and solvent-free product contains no liquid extenders or components that can migrate after curing.
The product is preferable to regular epoxy resin systems.
