PolyBrite® 95

• Excellent resistance to weathering including: UV radiation, extreme temperatures, as well as rain, ice and snow.
• Extends the useful life of the roof.
• PolyBrite 90.1 can reduce energy costs by decreasing roof surface temperature.
• Fungal and algal resistant – even in high temperatures.

• 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

• Protect and waterproof a variety of roof surfaces.
• Suitable for use on sprayed polyurethane foam, most metal roof systems, concrete, Thermoplastic and Thermoset single-ply membranes (primer may be required).
• Suitable for use over various conventional BUR and polymer modified roof membranes with smooth and mineral surfacing when primed with PolyBrite 97X Epoxy Primer or PolyBrite 98 one-part acrylic primer/bleed blocker.

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.
• 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 with PolyBrite 72 or PolyBrite 73 Elastomeric Mastic and PolyBrite Polyester Fabric.
• 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.
• Concrete surfaces cured with wax/resin based compounds can inhibit adhesion.

Application

• Stir well prior to application. Caution: Due To The Combustible Nature Of This Product, Do not use an electric mixer.
• PolyBrite 95 is recommended to be applied with high pressure sprayer for best appearance and coverage. It may also be applied by roller or brush applications.
• Apply PolyBrite 95 at 20 wet mils (1.25 gallon per 100 square feet) per coat. Typical application conditions require PolyBrite 95 be applied in two coats at 20 wet mils per coat. Consult Polyglass Technical Services for application rates for specific roof membranes and for job specific application specifications.
• Subsequent coats should be applied within 48 hours of prior applications to insure full and uniform adhesion. Coating must be evenly applied and pinhole-free. Before applying a subsequent coat of this product, the previous coat must be completely dry and cured. 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 4 hours of application. Drying time is dependent on temperature, humidity and film thickness.
• Do not thin product.
• Prior to using this product on new cap sheets (smooth or granulated), it is recommended to wait 30 days for weathering.

Application Equipment

This product may be sprayed, brushed, or rolled. Due to the high viscosity of the material, a high-pressure airless paint pump capable of producing 5000 PSI should be used. The pump should have a minimum of 2.5 gallons per minute output and be fed by a 5:1 transfer pump to prevent cavitation. Always use components rated for pump pressure. Hoses should be BUNA-N jacketed for prevention of moisture contamination. Hoses should have a minimum I.D. of 3 ⁄4" and an adequate working pressure. The spray gun should be high pressure (5000 PSI) with reverse-a-clean spray tip, 0.029–0.035 and a 50° fan tip. Any filters on spray rig or gun should be removed. Filters are required when applying fine finishes but not for roof coatings.

Do not use hose that has been used for Acrylics or other waterborne coatings as the liner absorbs moisture and initiates the silicone cure process.

Cleaning

Cleanup of spray equipment containing uncured material may be accomplished by flushing with VM&P Naphtha or mineral spirits. PolyBrite 95 cures by reacting with moisture and should not be left in spray guns, pump equipment and hoses for prolonged periods unless equipment contains moisture lock hoses, fittings and seals. Equipment without these components will transmit sufficient moisture vapor to gradually form cured material on hose walls and at unsealed connections potentially causing an increase in operating pressure and material flow restriction.
