Application and safety
Self-leveling screed under resin substrates should have a minimum compressive strength of 25 MPa (C25). The screed should not contain any additives that hinder adhesion, such as latex. Another parameter that helps in the assessment is the peel strength of the substrate, which should be at least 1.5 MPa.
Below is a list of compounds for which adhesion to the substrate has been confirmed in tests and in practice.
