Mastic rubber waterproofing bitumno
Mastic is made on the basis of rubber. Unicomponent, cold hardening. It is intended for a waterproofing of external surfaces of building constructions of residential, public, production buildings and constructions, including: roofs (on the concrete basis or a rolled carpet which became useless), the bases and walls of cellars from concrete or a brick. Use of this mastic for external anticorrosive protection of tanks, designs from sheet steel, pipes for gazo-, oil, and water supply systems is possible.
Mastic can be operated at a temperature from — 50 OS to +80 OS.
MBKH mastic is applied on previously cleared, dry or dried surface at a temperature from — 25 OS to +40 OS in one or two layers at the rate of 1,5 — 3 kg on one square meter (at a single-layer covering) and 3 — 5 kg (at a two-layer covering). It is diluted with uayt-alcohol, solventy, gasoline.
Time of drying of each layer at a temperature + 25OC not less than 24 hours.
Mastic is stored in a tight container in the ventilated room at a temperature not higher than + 30OC and protected from direct sources of heat.
