Bona's new silicone-based adhesive is called R851.

For pre-finished floors this product is great because it won't leave damaging stains if you accidentally get some on the surface of the wood during installation. Very easy to clean up.

Bona R851 is a moisture curing adhesive for wood floors. It requires no mixing and is solvent free. This adhesive will give you a better result than the competition by allowing more of the desireable natural movement of the wood once applied.

Flooring will be ready for use in one day due to R851's rapid shear strength development.

You will love how much easier R851 is to apply than other adhesives. Less work and no more arm fatigue! Greenguard Certified means less odor during installation.
