Excellent adhesion on most any 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, styrofoam, 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.

SURFACE PREPARATION:
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. PERMAFIBE™ 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. that exceed 1/16 of an inch, 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, a Red Iron Oxide Primer Sealer. Use a degreaser on galvanized or coated metals which have oils or surface treatments. Check PERMAFIBE™ 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™ to spot prime the penetrated areas, then use PERMAFIBE™ Primer for entire coated or galvanized surface. If applicable, replace or tighten screws or fasteners, then completely seal with PERMAPATCH™.

NOTE:
New masonry must age 60 days before priming or you can apply a sealer coat of CHALK FORCE™ Surface Conditioner & Chalk Sealer before PERMAFIBE™.

APPLICATION PROCEDURE:
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. 2 to 4 hours). Drying time will vary depending on temperature, humidity and location. Apply using brush or roller. Spread primer uniformly sealing seam and surrounding areas. Spread Rate will vary depending on substrate. Apply primer between 12 to 16 mils wet film thickness. Wait at least 6 hours before applying a compatible primer, paint or coating. APPLICATION HINT: Puncture pour holes in five gallon pails and pour a liberal bead directly on seam and follow with roller to distribute to seam and surrounding areas.

Clean Up:
Clean up all spills, tools and overspray immediately while the coating is still wet with warm soapy water.
