CERESIT CT 80 SUBSTRATE PREPARATION

Fixing thermal insulation boards: CERESIT CT 80 mortar shows good adhesion to carrying, compact and dry substrates. Adhesion of CT 80 to the prepared substrate is checked by gluing 10 x 10 cm blocks of EPS-boards and pulling off after 4-7 days. Reinforced layer application: When CT 80 is bonded (after approx. 3 days), any unevenness of the boards should be grounded with abrasive paper, any loose particles of insulation materials carefully brushed and the boards additionally reinforced.

APPLICATION OF CERESIT CT 80

CERESIT CT 80 should be poured into water and stirred until the homogenous mass is obtained. Fixing thermal insulation boards: mortar should be applied and then the board should be pressed to the wall. Reinforced layer application: the glass fibre mesh should be applied on the fresh mortar and smoothed evenly. Fixing mineral wool boards: before application of adhesive mortar CT 80 it is necessary to apply thin coat of it as ‘priming’ of surface. 4. Reinforcing layer application: before proper base coat layer application, it is necessary to do the ‘priming’ layer on Mineral Wool surface. After drying time (24 hours), the reinforced layer should be applied.

In case of contact with eyes, they should be rinsed with water and a general practitioner should be consulted.
