The mortar is intended for making the reinforced layer with glass fabric and gluing facade panels of foamed polystyrene and mineral wool in the TURBO-WSISI and TURBO-SISI insulation systems from the KREISEL company. Insulation boards glued with this mortar require additional fixing with expansion pins. Substrates for gluing insulation boards can be, among others: ordinary concretes, walls with ceramic, silicate, concrete elements, lightweight aggregate and cellular concrete with raw, plastered surfaces or with paint or texture coatings. The use of this mortar eliminates the need for a primer before applying thin-layer silicate-silicone plaster, which reduces the time and costs of insulation.
