DESTINATIONS OF USE
COPERMAST W is used for fixing insulating panels of various kinds such as glass wool, rock wool, polyurethane or polystyrene vertically, horizontally and on the ceiling, on internal wall surfaces of buildings consisting of concrete, brick, cement, wood and other materials provided they have a sufficient porosity to absorb a part of the water contained in the product during the drying process.
It is also suitable for gluing insulation panels on bitumen-polymer membranes: in this case, it is recommended to install an adequate number of exhalers to allow the disposal of residual moisture during the mastic drying process.
For slopes greater than 5% the gluing must be integrated with mechanical fixing.
It is also used for the bonding of insulating panels put to protect concrete foundations waterproofed with bitumen-polymer membranes before the burial phase with gravel or stabilized.
