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.

POLAROOF AC Application Guidelines
Surface Preparation
- Surfaces must be clean, dry, and free of dirt, loose debris, oil, grease, or any contaminants that may interfere with adhesion.
- The surface temperature must remain at least 5°F above the dew point during application and curing. Do not apply if substrate or ambient temperatures are expected to drop below 45°F (7°C), or if the area cannot be protected from precipitation within 4 hours of application.
- Do not apply POLAROOF AC to wet, damp, or frozen surfaces. All repairs to damaged or defective areas must be completed prior to application.
Application
POLAROOF AC should be applied directly from the container after gently mixing or stirring for at least 2 minutes using a low-speed method.
Apply using a brush, roller, or spray equipment. Install in two coats at a uniform wet film thickness of approximately 24 mils per coat to ensure complete coverage.
Apply the second coat after the first coat has set, typically within 2–4 hours. For brush or high-nap roller application, use light pressure and apply the second coat in a cross-direction to the first coat for optimal coverage and performance.
Spray Application
Use a 30:1 airless pump with a 3/8″ short hose and a 33–37 tip size.
Drying Time (Walkable)
Approximately 1.5 hours at 70°F (21°C) and 50% relative humidity.
Clean-Up
Clean tools and equipment with water before the coating dries. If the material has cured, solvent cleaning may be required.
Storage
Store in a dry area away from direct sunlight and protect from freezing. Keep containers tightly sealed.
Shelf life is up to 2 years from the date of manufacture when stored in original, unopened containers between 45°F (7°C) and 90°F (32°C).
Disposal
Dispose of waste in accordance with all applicable federal, state, and local environmental regulations. Incineration is the preferred method of disposal.
Safety Information
Read the product label and Safety Data Sheet (SDS) prior to use for important health and safety information.
Keep out of reach of children and pets.
