Bona R820 is a moisture cured silane-based adhesive for solid timber floors, including overlay, parquet, blocks and engineered floors.

R820 withstands the thrust created during expansion of a timber floor, like conventional adhesives, whilst having a low resistance against shrinkage. This means that tension between the timber and the substrate, to which the timber floor is fixed, is reduced giving a more stable floor.

Bona R410 or R540 moisture barrier can be used with R820 where a moisture barrier system is required.

• One component
• Can be used as a 2 component system with shorter setting times
• Water and solvent free
