AP-1300 Acrylic Primer Sealer

Product Fast Facts
Environmentally Friendly
Great Adhesion


United Asphalt‘s Armour Proof AP-1300 Acrylic Primer Sealer is a water-based, acrylic copolymer, primer/sealer and bonding compound developed to assist in the adhesion and preparation of surfaces for application of Armour Proof Coating products. Armour Proof AP-1300 Acrylic Primer Sealer bonds light dust, chalk or mineral surfaced membranes to enhance adhesion of Armour Proof Elastomeric membrane systems. It provides a barrier to asphalt membranes, preventing staining of the Armour Proof Coating products. It seals the porosity of various substrates for better film build and coverage of the subsequent coatings. AP-1300 ensures better bonding properties, creating a bond between the substrate and the coating system.

Coverage and Drying Time

Apply AP-1300 at a rate of 300-400 square feet per gallon, according to the substrate and condition. Normal drying time is 1-2 hours.

Preparation of Substrate

Surface must be pressure washed clean, free of all loose particles, dirt debris and other contaminants that could inhibit adhesion. Refer to the Armour Proof Coatings Specification for detailed instructions on how to prepare the specific substrate.

Limitations and Precautions

AP-1300 is a water-based primer and is not freeze-thaw stable. Do not apply AP-1300 when ambient air and substrate temperatures fall below 45°F, or if inclement weather is forecasted. Do not apply if ambient temperature will drop below 32°F 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 become unusable at temperatures below 32°F.
