PolyBrite® 75

• PolyBrite 75 has excellent exterior durability on roof exposure
• Better hail resistance than typical elastomeric roof coatings
• Flexible at low temperatures
• Excellent elongation at temperatures down to -15°F
• Excellent dirt pickup resistance
• UV resistance
• Excellent toughness to withstand foot traffic and routine rooftop maintenance activities
• High solar reflectivity, reducing roof surface temperatures and helping to prolong roof life and reduce energy costs
• Low toxicity and odor
• Easy application and simple cleanup with water

• 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

Approved over smooth and granulated BUR, SPUF, most metal roofs, modified bitumen membranes, concrete, exterior grade plywood rigid cover boards, and single-ply membranes. (May require a primer depending on age and condition.) A substrate adhesion test is recommended prior to product application.

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 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 colorant.
• 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 gallons 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.

Spray Equipment

PolyBrite 75 can be applied by conventional airless spray equipment designed for the purposes of field application of fluids, paints and coatings. The following minimums are recommended:

• Pump - 1 gal/min output; 2,000 psi
• Gun/Tip - Airless hand gun. Reversible tip with orifice sizes ranging from .027–.039.
• Hose - Minimum inside diameter of high pressure nylon hose of 3⁄8".

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.
