AquaMast cold bitumen-rubber roofing and waterproofing mastic

Mastics and liquid membranes

In AquaMast bitumen-rubber mastic, petroleum bitumen is modified with crumb rubber, and the mastic itself is supplied ready for application by spatula or brush. It is used to build mastic roofs, repair all types of roofs and waterproof structures buried in the ground; on roofs the coat is protected from the sun with mineral chippings or a reflective coating. Elongation is at least 100%, heat resistance is not lower than +80 °C, and the coating withstands water pressure for 72 h. Work is possible at −10…+40 °C; the mastic is not used inside residential premises.
