ROOF PRIME™ is recommended for well drained, SLOPED roof surfaces only. Excellent adhesion on weathered wood, shakes, plywood, primed metal, galvanized, aluminum, tin, copper, asbestos, asphalt, urethane, polyester, Styrofoam, fiberglass, Built-Up-Roofs, bonded roof gravel, rolled roofing, modified bitumen membranes, mineral surfaced roofing, stucco, concrete tiles (flat or barrel), slate, slab and various other substrates.
For residential, commercial and industrial applications.
Excellent for Mobile Home Roofs.

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. Wire brush if necessary. ROOF PRIME™ will resist mildew growth, but will not kill mildew already on the surface. Rinse thoroughly. Apply only to sound, well prepared roof surfaces. Patch any holes, cracks, seams, imperfections, etc. with PERMAPATCH™ Waterproofing Caulk & Sealant. Tape and seal all seams with PERMATAPE™, Polyester Fabric Tape. For poorly conditioned, unsound or loose roof surfaces (loose gravel) where substrate is chipping, cracking or brittle, inquire about PERMABOND™ Tie & Bond Primer Sealer.

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, roller or spray. Spread primer uniformly. Spread Rate will vary depending on substrate. Apply primer between 10 to 16 mils wet film thickness. Wait at least 12 hours before applying a compatible finish coating.

SPRAYERS:
Use at least a 1 gallon per minute piston type airless sprayer with a minimum tip size of .025.

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