Bona R778 is a polyurethane parquet adhesive that hardens without shrinking, through a chemical reaction. It is especially suitable for timbers that are particularly sensitive to swelling/moisture and for low/non-absorbent substrates. The long open time and good rib stability simplify the installation of wood planks.
