Acrylic Wall Finish Coat
Protect a Wide Variety of Substrates with a Durable, Waterproof Layer of Protection!
AP-7100 Acrylic Wall Finish Coat is a 100% acrylic elastomeric finish coating designed for protecting a wide variety of substrates, including stucco, concrete, brick, EIFS, metal and primed wood. AP-7100 Acrylic Wall Finish Coat bridges hairline cracks, protecting the substrate from wind-driven rain, allowing expansion and contraction with the varying temperatures. It also allows moisture vapor from within the substrate to escape without causing blistering or peeling of the coating. Once cured, AP-7100 provides a waterproof, durable, seamless, flexible, weather resistant layer of protection.

Limitations and Precautions
AP-7100 is a water-based, elastomeric, acrylic coating and is not freeze-thaw stable. Do not apply AP-7100 when ambient air and substrate temperatures fall below 50°F, or if inclement weather is forecasted. Do not apply over wet substrates or in inclement weather. Do not apply if ambient temperature will drop below 32°F in a 24-hour period or dew will settle before coating is allowed to dry. Do not store sealed containers in prolonged sunlight. PROTECT FROM FREEZING DURING SHIPMENT AND STORAGE. Do not store material at temperatures below 45°F. It will freeze and may become unusable at temperatures below 32°F.
