It is designed both for making a protective reinforced layer with glass cloth and for fixing Styrofoam panels, when insulating buildings using the light-wet method. It is a component of the BAUMASTER external wall insulation system. The panels fixed with this mortar require additional fixing with plastic expansion bolts. The substrates for fixing thermal insulation panels may include: regular concrete grades, walls made of ceramic elements, lightweight aggregate and cellular concrete with raw and plastered surfaces. Once mixed with water, it forms a homogeneous mass with grey colour.
