PERMAPRIME™ is a gray, elastomeric waterproofing, acrylic adhesive, insulating ceramic, Roof Primer Sealer. A waterborne, latex based, high resin content formula with ceramic pigments that seals and primes most roofing surfaces preparing it for a top coat. PERMAPRIME™ is pigmented to a gray finish that absorbs heat allowing it to dry faster. A waterproofing primer sealer that will bond, seal and help insulate most any new or existing exterior roofing surface. The high resin content provides excellent adhesion to the surface then forming a tight bond to the finish coat. The bond that is formed between PERMAPRIME™ and the finish coat eliminates any possibility of moisture under the finish coat thus extending the coatings life considerably. Designed as a primer coat for PERMAKOTE®, PERMAKOTE® SEMI-GLOSS, PERMAKOTE® SILVER SEAL and PERMAKOTE PLUS® Roof Coating Systems, but can be used as a primer for most any latex based paint or coating. A coat of PERMAPRIME™, PERMABOND™ or METAL-PRIME RED-OX™ is required as a primer for warranty conformance for the PERMAKOTE®, PERMAKOTE® SEMI-GLOSS, and PERMAKOTE PLUS® Roof Coating Systems. Inquire about all details including specific instructions and application procedures when a Nationwide Limited Material Warranty is desired.
Excellent adhesion on most any sloped or flat roof surfaces (not exceeding ½ of an inch of Ponding Water in any area of roof surface) including: weathered wood, shakes, plywood, clapboard, primed metal, galvanized, aluminum, tin, copper, asbestos, asphalt, urethane, polyester, adobe, brick, stucco, concrete, clay, masonry, slate, slab, built-up-roofs, modified bitumen membranes, rolled roofing, mineral surfaced roofing and various other substrates. For use on residential, commercial and industrial applications. For styrofoam, EPDM and rubber roofs inquire about PERMABOND™ Clear Adhesive Primer Sealer.
STAINS: Spot prime all stains before priming entire area. PERMAPRIME™ will seal most stains. If stain persists, a stain blocker should be used.
For proper adhesion it is essential that the surface is prepared properly. Clean Exterior Surfaces by thoroughly pressure washing with a water and chlorine solution using at least 1500 P.S.I. to remove any previous coatings, dirt, grease, and other foreign materials, especially mold, mildew and algae. PERMAPRIME™ will resist mildew growth, but will not kill mildew already on the surface. Rinse thoroughly. Remove loose paint and powdery substances. Patch any holes, cracks, seams, imperfections, etc., with PERMAPATCH™, Waterproofing Caulk & Sealant.
Metal: Clean surface of all grease, oil and foreign matter before priming. Rusted metal and uncoated metal must be primed with METAL-PRIME RED-OX™, a Red Iron Oxide Primer Sealer. Use a degreaser on galvanized or coated metals which have oils or surface treatments. Check PERMAPRIME™ adhesion on galvanized or coated metal by applying to a small area and evaluating after 48 hours. If lack of adhesion is present after evaluating, metal must be lightly scuffed without penetrating the coated finish or galvanizing. If applicable, use METAL-PRIME RED-OX™ to spot prime the penetrated areas, then use PERMAPRIME™ Primer for entire coated or galvanized surface.
NOTE: New masonry must age 60 days before priming or you can apply a sealer coat of CHALK FORCE™ Surface Conditioner & Chalk Sealer before PERMAPRIME™.
Stir well before using. Do not thin, use product as is. Do not apply when temperatures are below 45 degrees Fahrenheit or when humidity is very high. Do not apply when coating will be subjected to rain or heavy dew before it has had enough time to dry (approx. 1 to 2 hours). Drying time will vary depending on temperature, humidity and location. Apply using brush, roller or spray. Spread primer uniformly. Spread Rate will vary depending on substrate. Apply a coat between 10 to 16 mils wet film thickness. Wait at least 4 hours before applying a compatible paint or coating.
Airless Sprayers: Use at least a 1 gallon per minute piston type airless sprayer with a minimum tip size of .021. Remove all line filters and gun filters before spraying.
Clean Up: Clean all spills and tools immediately after use while coating is wet with warm soapy water.
