CERESIT CT 81

CERESIT CT 81 shows good adhesion to carrying, compact, dry and clean substrates free from substances decreasing adhesion of surfaces of walls, plasters and concretes. The adhesion to the existing plasters and paint coatings should be checked before starting the application. Any losses and uneven surfaces should be filled or covered. Any surface contaminant and other adhesion impairing substances, steam-tight paint coatings and the coats with low adhesion to the substrate should be removed.

Put CERESIT CT 81 into water and stir until a homogeneous mass without lumps is obtained. Apply the ready mortar with a trowel around the perimeter of the slab in a 3-4 cm wide strip and in several patches with a diameter of approx. 8 cm. Immediately apply the slab to the wall and press down. When CT 81 has set (after approx. 3 days), the boards should be sanded with sandpaper and start additional fastening with mechanical fasteners. 

The work should be carried out in dry conditions, with a temperature of ambient and substrate temperature of +5°C to +25°C. The sandy mortar has irritating properties, and the cement and lime content and lime content gives the product an alkaline reaction when mixed with water. Skin and eyes should be protected. In case of contact with eyes, rinse abundantly with water and seek medical advice.
