- Features & Benefits
- Extends the useful life of the roof.
- Resistant to dirt pick up.
- Resistant to asphalt staining, excellent “bleed through” resistance.
- By decreasing roof surface temperature, PolyBrite 71-HS can reduce energy costs.
- Fungal and algal resistant – even in high temperatures
- Offers excellent resistance to extended exposure to solar ultraviolet energy.
- Low VOC, non-flammable and presents minimal hazard to the applicator or the environment.
- Offers high tensile strength and elongation.
- 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
- Markets
- Applications
- Application Area
- Uses
- Functions as either a base or surface coating.
- Suitable for use on various aged smooth and granulated asphalt built-up and granulated polymer modified roof membranes, most metal roof systems, single-ply membranes (a primer may be required), concrete, exterior-grade plywood, SPF, rigid cover boards 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.
- Metal surfaces that display rusting or other oxidation, to be prepared with a grinder or wire brush as needed to remove surface contaminants.
- Visually inspect existing roof systems for conditions that may adversely affect adhesion of performance of newly installed products. Repair any visible deficiencies such as splitting, blistering, and buckling with PolyBrite 72 Premium Grade Elastomeric Flashing Compound or PolyBrite 73 Elastomeric Flashing Compound with StretchSpan Technology™ and PolyBrite Polyester Fabric.
- Repair all metal and non-metal flashings, edges, drains, valleys and through-roof penetrations.
- Do not apply to wet or visibly damp surfaces, or surfaces previously covered with coal tar based products or Kynar® finishes.
- Concrete surfaces cured with wax/resin based compounds can inhibit adhesion
Application
- Stir well prior to application. To field tint this product, please use a water-based, exterior-grade pigment.
- Apply with high pressure sprayer for best appearance and coverage, however the product may be applied by roller or brush applications.
- Apply at 24 wet mils (1.5 gallon per 100 square feet) per coat. Typical application conditions require two coats at 24 wet mils per coat. To minimize potential voids or pinholes in coating application, apply second coat perpendicular to the first.
- Allow coating to dry overnight prior to applying second coat.
- Apply only when ambient temperatures are 50°F 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 120°F.
- 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.
