Cold mastic consists of a mixture of petroleum bitumen, crushed rubber crumb, an organic solvent (TS - 1 or White - spirit) and an antiseptic.(//tractor-service.com)

Method of application:
Before using the mastic, preheat it to a temperature of 160 - 180 oC and mix thoroughly.
Clean the treated surface from dust,oils, rust and other contaminants, as well as free water, snow and ice.
The surface should be dried and heated to a temperature above 0°C, after which the bituminous mastic will lay down well and solidify reliably.
The material can be applied at temperatures from - 20°C to + 40°C.
The drying time of the mastic layer depends on its thickness, surrounding conditions, and the type of structure being processed.
The consumption of the material varies depending on the porosity, roughness, absorbent capacity of the base, as well as on the equipment used.
