RAVAPROOF AVIPAST

AVIPAST is a water based bituminous emulsion in a pasty form. After maturation it create an indissoluble coat that cannot be affected by dilute acid and alkaline solutions.

PRIMARY USES
Due to its excellent adhesion and its easy application, its suitable for protecting concrete substructures, brick constructions, floors, inclined roofs etc. and protection against moisture and humidity. It can also be combined with concrete and sand and latex bonding agent as to create a plastic mortar, with excellent mechanical resistance, which can be applied on industrial floors, gymnasium flooring, etc.

COMPOSTITION
AVIPAST is produced by bitumen, in combination with special additives and water. It has a pasty form, and doesn’t contain any solvent.
