Description of material
Zumrut 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 Zumrut Kimya Corporation. Its application provides for the creation of a reliable, complete roofing system.
Application areas
Zumrut hot roofing mastic 41 is designed for the installation and repair of roofs (when sealing cracks, hollows in cement/sand and asphalt underlayments, concrete plates; restoration of dressing compound of roof cladding; installation of roof drains; in places where roof cladding contacts pipes, caps; fi reless installation of roll-fed roofi ng materials) and waterproofi ngs (coating of steel structures, concrete blocks, columns that contact the ground, steel, concrete engineering structures, including pipelines).
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 of Hot Roofing Mastic
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
Packing
- Cartons with plastic liners (15–25 kg blocks)
