Bona R850 is an elastic 1-component silane based adhesive for solid and engineered wood flooring. The hardened adhesive is able to withhold thrust during expansion, whilst the resistance against shrinkage is very low – therefore tensions to the sub floor are reduced. The use of primer is generally not necessary but is compatible with R410 primer. The adhesive hardens by a chemical reaction with moisture.
