MBR hot bitumen-rubber mastic (grades 65, 75, 90, 100) — GOST 15836-79
Hot mastic of bitumen and crumb rubber for protection of underground pipelines, roof joints and structures in the ground; four grades.

The universal water-based, solvent-free AquaMast paste works outside and inside buildings: on foundations, on floors of residential premises, and for anti-corrosion and anti-capillary protection of concrete. It goes onto sand-lime brick, aerated concrete and foam concrete, concrete, lime-cement plaster, timber and old bituminous coatings, and if necessary can be diluted with water in any proportion. The coating becomes watertight after 8 h at +20 °C and reaches its final properties after 3–4 days. The paste is not used on roofs; it is applied by spatula or float at +5…+40 °C.
