Surface for application should be cleaned from any oils, rust, detergents and other substances that prevent adhesion. If there are areas in the form of cracks, cavities on the surface - they must be repaired using the easy cement mixes Teknorep 300 and Teknorep 300 EXThe insulated surface must be dry and prepared.
