Coverage & Drying Time

Apply AP-3100 at a minimum rate of 1 to 1.25 gallons per 100 square feet per coat, according to the substrate and condition. Two coats are recommended. Prepare all seams, penetrations and other flashing details with AP-3100 Acrylic Base Coat and our polyester reinforcement. A minimum of 16 mils DFT is recommended to achieve optimal performance of the coating. Normal drying time is 2-4 hours. Armour Proof Coatings recommends applying AP-3100 by airless spray in multiple coats in a crosshatch pattern. This will avoid pinholes and ensure a uniform film build. Backrolling may be necessary. Refer to the Armour Proof Coatings Specification for detailed instructions.

Application

Apply by brush, medium nap roller or airless sprayer.
Airless spray: Minimum pump pressure 3000 psi
Tip Size: .027”-.039” (.031” recommended)
Hose: Use 3/8” up to 100’, from 100’ to 200’ use ½” or larger

Preparation of Substrate

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

Limitations and Precautions

AP-3100 is a water-based elastomeric acrylic coating and is not freeze-thaw stable. Do not apply AP-3100 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 as it will freeze and may become unusable at temperatures below 32° F.
