Bona® R580 moisture barrier sealer is a unique, single coat, fast setting, silane-based moisture barrier.
Bona R580 is a one component silane-based moisture barrier for securing damp sub floors. For faster bonding Bona R580 can be used as a two component system - just add water from the bag enclosed.
Bona® R580 moisture barrier sealer optimizes adheasion to, and provides a protective membrane over substrates where the moisture content exceeds 3 lbs or 75% relative humidity.1 It is a moisture cured, solvent and water free, silane-based compound.
1 or 2-component system: 2-component system includes a catalyst to accelerate setting time.
