TECHNONICOL MASTIC #57


Application areas

Reflective mastic for protection of roofs against UV-radiation and thermal aging. Use for:
– Installation of protective layer on new bitumen, polymer-bitumen mastic roofs;
– Recovery of protective layer on old bitumen, polymer-bitumen mastic and roll-fed roofs;
– Corrosion protection of roof coverings.

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


Before application and during use carefully mix mastic for uniform distribution of the aluminum pigment. Apply mastic using a small paint brush, a roller or through use of an airless spraying unit. It is recommended to be applied in two layers of mastic. Mastic surface coverage for one layer:
– on mastic roof — 0.4 kg/m2;
– on old roll-fed roof — 0.6 kg/m2;
– on metal roof — 0.4 kg/m2.

Storage


  • Store in a dry place protected against sunlight at a temperature between –20°C and +30°C. Guaranteed storage period — 12 months.
  • Has thin coverage
  • Can be used in sub-zero temperatures
  • Protects against corrosion and premature aging
  • Has energy-conservation properties
  • Protects against surface heating
