Step By Step

CT 190 should be poured into the measured amount of cool clean water and stirred with the drill by means of a mixer until the homogenous mass is obtained without lumps.

(1) Fixing thermal insulation boards: The ready mortar should be applied with a trowel along the board edge forming a strip of 3-4 cm wide and a few spots with the diameter of approx. 8 cm.  Immediately, the board should be pressed to the wall with a few slight blows of a long float. The boards should be fixed tightly one at the other in one surface with the preservation of "brick like manner" of vertical connection. Let dry for 3 days. (2) Armoured layer application: The ready mortar of 3-4 cm-thick layer should be spread along the surface of the boards by means of a smooth long steel float. The glass fibre mesh should be applied on the fresh mortar (with 10-cm overlaps), and then the second 1-2cm-thick layer should be applied and smoothed evenly so that the glass fibre mesh should not be visible.
