TECHNONICOL MASTIC #41 (EVRICA)

Application areas

TECHNONICOL hot roofing mastic #41 is designed for the installation and repair of roofs (when sealing cracks, hollows in cement/sand and asphalt underlayment, concrete plates; restoration of dressing compound of roof cladding; installation of roof drains; in places where roof cladding contacts pipes, caps; fireless installation of roll-fed roofing materials) and waterproofing’s (coating of steel structures, concrete blocks, columns that contact the ground, steel, concrete engineering structures, including pipelines).

Description of material

TECHNONICOL hot roofing mastic #41 is produced from roofing bitumen’s, modified by polymers and mineral filler. Due to its similar structure the mastic is completely compatible with the roofing and waterproofing materials produced by the TechnoNICOL Corporation. Its application provides for the creation of a reliable, complete roofing system.

Method of application

The mastic is warmed to a temperature of 160-180°С and is applied in a liquid state to the primer-coated base by a putty knife, small paint brush, or by pouring and leveling.

Storage

  • Store in a dry place protected against sunlight at a temperature between –20°C and +30°C. Guaranteed storage period — 12 months.
  • Effective application in sub-zero temperatures
  • Has cost-effective coverage and price per square meter
