POLAROOF NW
Premium Waterproofing Coating for Metal Roofs, Concrete Decks, and Ponded Water Applications
POLAROOF NW is a premium-quality, single-component waterproofing coating designed for maximum durability and long-term flexibility on metal roofs, concrete decks, and roofing systems exposed to ponded water. Its solvent-based formulation allows application across a wide temperature range, making it suitable for demanding field conditions and year-round installation.
Engineered for permanent performance, POLAROOF NW forms a seamless, fully adhered membrane that maintains exceptional flexibility and toughness over time. It is designed to bridge hairline cracks, accommodate structural movement, and resist impingement attack without cracking, peeling, or loss of adhesion.
In addition to waterproofing performance, POLAROOF NW can function as a vapor barrier, making it especially suitable for cold-storage and temperature-controlled environments. The cured membrane provides strong resistance to moisture intrusion while maintaining stability under continuous environmental stress.
Available in 24 standard colors, with custom color matching upon request.

POLAROOF NW Application Guidelines
Surface Preparation
Surfaces must be clean, dry, and free of dirt, loose debris, oil, grease, or any contaminants that may interfere with proper adhesion.
Application
Do not apply POLAROOF NW if substrate or ambient temperatures are expected to drop below 35°F (2°C) within 4 hours of application. The surface temperature must remain at least 5°F (3°C) above the dew point during application and curing.
Do not apply to wet, damp, or frozen surfaces. Application must be protected from precipitation for a minimum of 4 hours.
Stir thoroughly for at least 2 minutes using a low-speed drill prior to application. Do not thin the product.
Apply in two coats using a soft brush, medium-nap roller, or airless spray equipment. Use a smooth, even technique to achieve a uniform coating thickness.
Spray Application
Use a 30:1 airless pump with a 1/2″ hose, a 3/8″ whip, and a 35–41 tip size.
Recommended Thickness
Two coats will yield approximately 18–26 mils dry film thickness (DFT).
Drying Time
Approximately 3 hours at 70°F (21°C) and 70% relative humidity.
Clean-Up
Clean tools and equipment with xylene or toluene solvent.
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 40°F (5°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.
