PolyBrite® 70

• Extends the useful life of the roof.
• UV resistant.
• Decreases roof surface temperature, which can reduce energy costs.
• Offers high tensile strength and elongation.
• Resistant to dirt pick up and is fungal and algal resistant.
• Low VOC
• Non-flammable.

• 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

• Suitable for use on various conventional smooth and granulated BUR and polymer modified roof membranes with smooth and mineral surfacing, sprayed polyurethane foam, most metal roof systems, single-ply membranes, concrete, exterior-grade plywood, rigid coverboards such as Securock®. A substrate adhesion test is recommended prior to product application.
• Suitable for use on cementitious stucco, EIFS and other masonry surfaces.
• PolyBrite 70 is available in a quick-set version (PolyBrite 70-QS).
• Primers or special precautions may be needed, consult Polyglass Technical Services.

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 PolyFlash 1C or PolyBrite 73 Elastomeric Flashing Compound with StretchSpan Technology™ and PolyBrite Polyester Fabric.
• Repair any metal and non-metal flashings, edges, drains, valleys and through-roof penetrations.
• Do not apply to wet or 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. Proper preparation is required, contact Polyglass Technical Services for proper procedure.

Application

• Stir well prior to application. To field tint this product, please use a water-based, exterior-grade pigment.
• Apply with airless 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 maximum) 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.
• Let the first coat dry a minimum of 4 hours prior to applying the second coat. Note: Weather conditions can prolong dry time.
• 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 or the temperature of the roof surface is over 140ºF.
• Do not thin product. Do not heat outside of container. Do not apply at temperatures greater than 120ºF.
• This product should not to be used where ponding water conditions exist

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.
