what is the importance of choosing the right adhesive for parquet?
The choice of adhesive depends, among other things, on the nature and flatness of the substrate, the properties and dimensions of the floor elements, the moisture sensitivity of the wood, the presence of underfloor heating, the compatibility with the substrate and any primers, the processing properties...
There are different types of parquet adhesive, of which the 1-component polymer adhesives and the 2-component (epoxy) polyurethane adhesives can be used for most applications due to their versatility.
Rigid or flexible adhesives
Rigid adhesives are recommended if you want to counteract the movement of the wood. Due to their strong adhesion and low stretch, these adhesives will increase the burden on the substrate. This adhesive type therefore requires a substrate with high cohesive strength, otherwise the transmitted stresses can lead to an adhesive fracture of the substrate.
Flexible adhesives can compensate for the movements of the wood due to their elastic nature and then return to their original shape.
