The task of wood floor adhesives is to firmly bond the organic wood floor elements to the generally inorganic screed. The adhesive must hold the wood in place, connect it to the underlying screed and transfer stress originating from the natural expansion and contraction of the wood to the generally rigid screed. The undesired but natural movement of the wood can become visible in cupping, joint formation, or in extreme situations failure of the adhesive or screed.
Classes of Adhesives for Wood Floor Bonding
The lap shear value is determined by bonding two overlapping wooden pieces that are then tensile strength tested in a standard test rig after curing.
The application range of the adhesives has to be given and confirmed by the manufacturer i.e. the types of substrates, screeds, woods, plank dimensions and environmental conditions, together with the limitations and necessary installation procedures.
Today in Europe one component SMP based adhesives dominate the wood floor bonding market due to their versatility, resulting in a wide assortments ranging from basic solutions for engineered wood to premium solutions for large solid wood planks. Additionally SMP based adhesives can be supplied in plastic pails and residual adhesives or stains are easy to clean-up and remove.
