- Product Highlights
- PolyBrite 31 CB exhibits wet hide during installation and dry hide once cured.
- The product’s flexibility allows it to expand and contract to accommodate normal roof movement, therefore avoiding surface damage.
- Exceptional product flow and leveling characteristics results in ease of application.
- Features & Benefits
- Easy application due to exceptional product flow.
- Superior wet and dry hide.
- Offers excellent resistance to extended exposure to solar ultraviolet energy.
- By decreasing roof surface temperature, PolyBrite 31 CB can reduce energy costs.
- Offers good tensile strength and elongation.
- Resistant to dirt pick up.
- Fungal and algal resistant – even in high temperatures.
- Low VOC, non-flammable and presents minimal hazard to the applicator or the environment.
- Benefits
- Polyglass offers all the product components needed for these systems – one stop shop
- A variety of systems which can be used on new construction or tear off and replace roofs
- Offers excellent resistance to extended exposure to solar ultraviolet energy
- Can decrease the roof surface temperature, thereby reducing energy costs
- Superior tensile strength for a strong roof
- Easy to install, no kettle, no torch and no special tools or equipment needed other than a heavy roller
- Much safer than traditional hot asphalt BUR or torch down systems
- Should reduce the cost of insurance for the roofing contractor
- Low VOC and odor - presents minimal hazard to the applicator or the environment
- Resistant to dirt pick-up – easy to maintain
- Fungal and algal resistant
Applications & Uses

- Applications
- Application Area
- Compatible Substrates & Surfaces
- Uses
- Protect and waterproof a variety of roof surfaces.
- Suitable for use on various conventional smooth and granulated BUR and granulated polymer modified roof membranes, most metal roof systems, PVC single-ply membranes (Primer may be required), concrete, rigid coverboards such as Dens-Deck® and Securock®. A substrate adhesion test is recommended prior to product application.
- Suitable for use on cementitious stucco, EIFS and other masonry surfaces.
- Application Instruction
Surface Preparation
- All surfaces to receive coating must be clean, dry, and free from any foreign matter such as dirt, oils, grease, or other debris that could inhibit the adhesion capabilities of the newly installed products.
- Existing roof systems to be visually inspected for conditions that may adversely affect adhesion of performance of newly installed products. Repair any visible deficiencies such as splitting, blistering, and buckling.
- Visually inspect all metal and non-metal flashings, edges, drains, valleys and through-roof penetrations and repair as needed by project conditions.
- Do not apply to wet or visibly damp surfaces or surfaces previously covered with coal tar-based products or Kynar® finishes without proper preparation.
- Concrete surfaces cured with wax/resin-based compounds can inhibit adhesion.
Application
- Stir well prior to application.
- PolyBrite 31 CB may be applied by high pressure spray, roller, or brush application methods.
- Apply PolyBrite 31 CB at 24 wet mils (1.5 gallon per 100 ft2 ) per coat. Typical application conditions require PolyBrite 31 CB be applied cross hatch in two coats at 24 wet mils per coat.
- Allow coating to dry overnight prior to applying second coat.
- To minimize potential voids or pinholes in coating application, apply second coat perpendicular to the first.
- Apply only when ambient temperatures are 50ºF and rising. Cold weather could result in uneven application and improper curing of product. Do not apply if there is a threat of inclement weather within 24 hours of application.
- Do not thin product. Do not heat outside of container. Do not apply at temperatures greater than 120ºF.
- Prior to using this product on new cap sheets (smooth or granulated), it is recommended to wait 30 days for weathering.
Cleaning
- Clean equipment and overspray with water.
- Clean hands with waterless hand cleaner.
- Application tools and equipment can be cleaned with lukewarm water and soap, followed by a rinse of isopropanol, acetone, or Simple Green®. Recirculate through lines and gun until residual coating is removed.
- Do not use mineral spirits, xylene, toluene, or VMP & naptha solvents.
