Floor levelling compounds are primarily a product for correcting small variations in floors to provide a level, defect-free surface for floor finishes. They are usually necessary to avoid unevenness in the substrate material being telegraphed through the flooring, particularly when resilient sheet flooring is being used,
However, adding further layers over the structural floor increases the risk of failure due to a lack of or poor adhesion between the layers.
This bulletin provides guidance on the generic types of floor levelling compounds available and the preparation required prior to their application. In all applications, it is important to specify and install floor levelling compounds according to the product manufacturer's instructions.
