CERESIT® CT 87 is designed to warm up external walls of the buildings by application of external thermal insulation composite system using EPS- or mineral wool façade boards. CT 87 is used for fixing of facade boards and for applying the reinforcing protection layer to insulate the newly constructed objects as well as older buildings to be thermo-renovated. CT 87 is resistant to the formation of cracks, is flexible, light, has a homogenous consistency and it is easier to be stirred, applied and spread. Available pack size: 25 kg
Fixing thermal insulation boards: CERESIT CT 87 shows good adhesion to carrying, compact and dry substrates. The adhesion to the existing plasters and paint coatings should be checked before the application. Armoured layer application: when CT 87 is set, any unevenness of the boards should be ground with abrasive paper, then any loose particles of insulation materials should be brushed whereas the boards should be additionally reinforced.
CERESIT CT 87 should be poured into cool clean water and stirred until the homogeneous mass is obtained. Fixing thermal insulation boards: the mortar should be applied along the board edge and immediately, the board should be pressed to the wall. Reinforced layer application: the mortar should be spread along the surface of the boards. The glass fibre mesh should be applied on the fresh mortar, it should be immersed and filled smoothly.
The armoured layer should not be applied on highly insolated surfaces and the applied layer should be protected against rain. Application should be performed in dry conditions with the substrate and ambient temperature from +5 °C to +25 °C. Skin and eyes should be protected.
CERESIT CT 87 mortar is an element of CERESIT Ceretherm ETICS systems. CT 87 mortar is used for fixing of EPS- or mineral wool facade boards and for applying the reinforcing protection layer to insulate the newly constructed objects as well as older buildings to be thermo-renovated.
CERESIT CT 87 can be applied on walls, plasters, mosaics and concretes free from grease, bitumen, dust and other substances decreasing adhesion.
