Description: United Asphalt‘s Armour Proof AP-2300 Acrylic Mastic is an acrylic, heavy bodied elastomeric mastic. It offers good elongation and tensile strength properties, resisting lateral movement and allowing for expansion and contraction. Armour Proof AP-2300 Acrylic Mastic is used for many different applications, including cracks, seams, fasteners and penetrations.

Application: Apply AP-2300 by brush or trowel. When necessary, embed AP-8100 Series Polyester reinforcement into the wet product and smooth out free of all wrinkles and fishmouths. Roof coating may be applied after 2-6 hours of application.

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-2300 is a water-based, elastomeric, acrylic coating and is not freeze-thaw stable. Do not apply AP-2300 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.
