It is designed both for making a protective reinforcing layer with glass cloth on facade thermal insulation panels and for fixing panels to the substrates, when insulating buildings using the light-wet method. It is a component of the BAUMASTER external wall insulation system for buildings. 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.
