Description
Polaroof AC®
Premium Acrylic Elastomeric Roof Coating
Polaroof AC® is a high-performance, acrylic elastomeric roof coating engineered to deliver long-term waterproofing, energy efficiency, and structural protection across a wide range of roofing systems.
Formulated with advanced mineral reinforcement and proprietary acrylic chemistry, Polaroof AC creates a durable composite membrane that shields substrates from water intrusion, corrosion, UV degradation, and stress fatigue caused by thermal cycling.
Designed for performance in all climates, Polaroof AC maintains flexibility across a broad temperature range — resisting cracking in cold weather and softening or flow in extreme heat.
Available in 24 standard colors, with custom color matching upon request.

Preparation and Application
Surface Preparation
Surfaces must be dry, free of dirt, loose debris, oils, grease or any substance that could interfere with adhesion. Surface must remain at least 5°F above dew point during the application and curing process. Do not apply if the substrate or air temperature is predicted to drop below 45°F (7°C) or if the area cannot be protected from precipitation within 4 hours after application. Do not apply POLAROOF AC to wet, damp, or frozen surfaces.
All repairs of damage or defects must be made prior to application.
Application
POLAROOF AC is applied straight out of the can after 2 minutes of gentle low speed mixing or stirring. Apply the product using brush, roller, or spray technique. Apply in 2 coats to a uniform wet film thickness of about 24 mils per coat to insure complete coverage on the 2nd coat. Apply the 2nd coat after the 1st coat has set (about 2-4 hours). For soft brush or high nap roller application, use light pressure and coat in a cross direction to the 1st coat.
Spray Application
For spray application use 30:1 airless pump, 3/8″ short hose and 33 to 37 tip
Drying Time (Walkable)
Approximately 1.5 hours at 70°F (21°C) and 50% RH.
Clean up
Clean tools and equipment with water before the POLAROOF AC dries; after that solvent cleaning may be necessary.
Storage
Store in a dry area and protect from direct sunlight and freezing. Keep container tightly sealed. Shelf life is 2 year from date of manufacture when stored in a factory sealed container between 45ºF (7ºC) and 90ºF (32ºC).
Disposal
Waste disposal must be in accordance with existing federal, state and local environmental control laws. Incineration is the preferred method of disposal.
Read the container label warning and Safety Data Sheet (SDS) for important health and safety information prior to the use of this product.
