• Premium quality waterproofing coating for metal roofs, concrete decks and roofs with ponded water.
  • Designed for permanent flexibility and toughness, to bridge and move with hairline cracks, and to resist impingement attack.
  • Tough, elastic coating that seals and protects roofs that are exposed to extreme conditions.








24 Standard Colors. Custom Colors are available.


POLAROOF NW is a premium quality single component waterproofing coating for metal roofs, concrete decks and roofs with ponded water. It is solvent-based so may be applied in a wide temperature range. POLAROOF NW as a vapor barrier is suitable for cold-storage applications. It is designed for permanent flexibility and toughness, to bridge and move with hairline cracks, and to resist impingement attack.

Outstanding Features

  • Produces a fully adhered, seamless, high density, waterproofing membrane that is totally vaporproof (may be used as a vapor barrier).
  • Protects substrate against rust, corrosion, UV damage, acid rain, and fungal attack.
  • Easy to apply straight out of the container by brush, roller, or airless spray.
  • Resists fungal attack.
  • May be used on vertical, pitched, and horizontal surfaces and withstands ponding water.
  • Remains flexible, tough, and weatherproof at low temperatures and will not flow at high temperatures.
  • Will not re-emulsify or wash away with rainwater.
  • Ten year material warranty.

Preparation and Application

Surface Preparation
Surfaces must be dry, free of dirt, loose debris, oils, grease or any substance that could interfere with adhesion.

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.

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).

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.
