Application areas
Application areas for TECHNONICOL roofing mastic #33:
– Installation of mastic roofs and repair of all kinds of roofs;
– Waterproofing of engineering structures (basements, cellars, piles and other facilities buried in the ground or coming in contact with the damp environment);
– Indoor waterproofing (bathrooms, pool floors, balconies, cellars)
Description of material
The water-emulsion material produced by dispersion of bitumens in a water solution of emulsifiers and modification through latex. It does not contain solvents. Mechanized application drastically reduces the time needed to carry out the works. The mastic has enhanced properties. These coverings have a wide range of operating temperatures.
Method of application
TECHNONICOL mastic # 33 can be applied both manually and mechanically. During manual application, the mastic is applied using a small paint brush or a roller. During mechanized application, the mastic is applied to the base using an airless spraying unit. In order to increase productivity (reduction of the time needed for insulating cover curing), the mastic is applied together with a coagulant solution (a water solution of calcium chloride) using a two-channel apportioning installation. Mastic surface coverage for one layer: 2.5–3.5 kg/m
