M850 PolrShield
Premium Elastomeric White
USES: M850 PolrShield is a relatively high solids, liquid-applied acrylic elastomer coating. It forms a seamless, self-flashing monolithic waterproof membrane that chemically bonds to the substrate or base coat. PolrShield fills and reinforces gaps, has outstanding strength, and long term flexibility.
DESCRIPTION: M850 PolrShield has a solar reflective surface with a durable acrylic finish that resists dirt. PolrShield also has an excellent coverage rate with low labor costs. In addition, PolrShield is resistant to chemical, biological, and ultraviolet (UV) degration.
DIRECTIONS: Clean away all loose gravel, dirt, vegetation, and debris from the application area. Seal any leaking penetrations and repair all membrane breaks with M300 RubrMastic. Prime the surface to be coated along with any uncoated masonry and new metal with M700 RubrGard. Use a roller or asphalt emulsion spray equipment, to apply both RubrGard and M850 PolrShield directly from their container without diluting. To apply over built-up roofs with PolrShield, thoroughly stir the PolrShield just prior to application. Then apply PolrShield at the rate of 3/4 gallons per 100 square feet. To install a waterproofing fabric with PolrShield, select either PolyWeb or GlasWeb. Then, generously brush 1 1/2 gallons per 100 square feet of PolrShield in a complete 3 foot wide strip as an adhesive beneath the first roll of fabric. Set the sheet into the PolrShield, making sure it unrolls straight and without any wrinkles. Carefully press the sheet into the PolrShield by lightly brushing the surface until complete adhesion and penetration is achieved. Do not step on the sheet until the PolrShield has set up. Continue installing each successive roll of fabric by overlapping the prior sheet 2" on the seams. For each additional layer of fabric, repeat the above process using 2 gallons per 100 square feet of PolrShield in a complete interply application. Center the rolls of each additional layer of fabric over the seams of the prior layer. Apply a final surface coating of PolrShield at the rate of 3 gallons per 100 square feet. To apply over new roofs with PolrShield, after preparatory cleaning, apply PolrShield at the rate of 3/4 gallons per 100 square feet to all horizontal, vertical joints, and seams. Before PolrShield dries, embed PolyWeb or GlasWeb (at least 6" wide) over center of seam. Work the sheet into the PolrShield so as to saturate the sheet. Apply the first coat of PolrShield at the rate of 1 1/2 gallons per 100 square feet. Roll or spray in one direction only, avoiding wide sweeps. Allow PolrShield to dry for 24 hours. After first coat has dried, apply a second coat of PolrShield at the rate of 1/2 gallons per 100 square feet in a right-angle direction to the first coat.
