Vetoproof AM768 is a monolithic, elastomeric, synthetic air barrier membrane designed to be rolled, sprayed, or troweled onto exterior above-grade wall assemblies to mitigate air infiltration/exfiltration and water penetration while remaining permeable to the passage of water vapor. It may also be used as a liquid-applied flashing.
All surfaces should be dry and free from contamination, such as oil, grease, loose particles, decayed matter, moss, algal growth, laitance, and all traces of mold release oils and curing compounds. This is best achieved by lightly gritblasting the surface. Where moss, algae, or similar growths have occurred, treatment with a proprietary biocide should be carried out after the grit-blasting process. Spalled and deeply disintegrated concrete should be removed to sound concrete and repaired with a Saveto repair system.
Concrete substrates should be at least 14 days old; bituminous substrates should be at least 12 months old before overcoating with Vetoproof AM768.
Apply Vetoproof AM768 with a roll, trowel, or airless spray machine. Apply the first coat of Vetoproof AM768 and allow it to dry for 6-12 hours, depending on the ambient temperature.
Remove Vetoproof AM768 from tools, equipment, and mixers with clean water before the initial set. Cured material can only be removed mechanically.
