Description
Premium Waterproofing Coating for Metal Roofs, Concrete Decks, and Ponded Water Applications
Polaroof NW is a high-performance, single-component waterproofing coating engineered for extreme durability and flexibility. Ideal for metal roofs, concrete decks, and surfaces prone to ponded water, this solvent-based coating provides long-lasting protection under a wide range of temperatures and environmental conditions. Polaroof NW also functions as a vapor barrier, making it suitable for cold-storage applications.
Available in 24 standard colors, with custom color matching upon request.
Key Benefits

Technology
Ethylene Elastomer
Preparation and Application
Surface Preparation
Surfaces must be dry, free of dirt, loose debris, oils, grease or any substance that could interfere with adhesion.
Application
Do not apply if the substrate or air temperature is predicted to drop below 35°F (2°C) within 4 hours after application. The application surface must remain at least 5°F (3°C) above dew point during the application and curing process. Do not apply Polaroof NW to wet, damp, or frozen surfaces. Do not apply if the area cannot be protected from precipitation for at least 4 hours after application.
Polaroof NW is applied directly out of the container after at least 2 minutes of low speed drill stirring. Do not thin the product. Apply in 2 coats using a soft brush, medium nap roller, or airless sprayer in a smooth, even technique to achieve a uniform coating thickness.
Spray Application
For spray application use 30:1 airless pump, 1/2″ hose with 3/8″ whip and 35 to 41 tip
Recommended Thickness
2 coats yield 18 to 26 mils Dry Film Thickness (DFT)
Drying Time
Approximately 3 hours at 70°F (21°C) and 70% RH.
Clean up
Clean tools and equipment with xylene or toluene solvent.
Storage
Store in a dry area and protect from direct sunlight and freezing. Keep container tightly sealed. Shelf life is 2 years from date of manufacture when stored in a factory sealed container between 40ºF (5ºC) 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.
