SURFACE PREPARATION:
For proper adhesion and maximum performance it is essential that the surface is prepared properly. The surface must be absolutely clean, dry, and free of all scaling rust, mill scale, dirt, grease, wax, oil, chalk, incompatible paint or detergent/chemical films. Rusted metals should be cleaned down to remove all scaling and flaking rust by scraping, wire brushing, sanding or sandblasting. Be sure the surface is thoroughly de-greased and moisture free before priming. Use a degreaser on galvanized or coated metals that have oils or surface treatments.
Apply only to a sound, completely dry, well prepared roof surface. Leaks must be repaired before any coating is applied. Prepare surface by thoroughly pressure washing with a water and chlorine mixture using at least 1500 P.S.I. to remove any previous coatings, dirt, grease, and other foreign materials, especially mold, mildew and algae. METAL-PRIME RED-OX™ will resist mildew growth, but will not kill mildew already on the surface. Apply METAL-PRIME RED-OX™ in rusted or corroded areas that need to be treated. TWO COATS OF METAL-PRIME RED-OX™ MUST ALWAYS BE APPLIED. Patch any holes, cracks, flashings, valleys, vents, etc., with PERMAPATCH™ Elastomeric Patching Compound, a Waterproof Caulk and Sealant, after METAL-PRIME RED-OX™ application. Tape & seal all seams with PERMATAPE™, a Polyester Fabric Tape or PERMASTIK™ Butyl Tape. NOTE: METAL-PRIME RED-OX™ Rusted Metal Primer Sealer may be used as a saturant for the PERMATAPE™ with the second coat of METAL-PRIME RED-OX™ applied over the PERMATAPE™.

APPLICATION PROCEDURE:
Stir well. You will notice METAL-PRIME RED-OX™ to be quite thick. This is necessary to hold the high solids of zinc and red iron oxide pigments in suspension. If thinning is necessary, use water sparingly, not exceeding 8 ounces per gallon of primer. Be sure to only thin the amount of product that will be used within 24 hours, or settling of pigments may occur. If possible, METAL-PRIME RED-OX™ should be applied as is from the container, no thinning. Apply at temperatures above 40℉ and when primer will not be subjected to rain or heavy dew before it has had a chance to dry (approximately 2-4 hours). Apply with short nap roller, brush or at least a 1 gallon per minute piston type airless sprayer with a minimum tip size of .027. Apply uniformly and do not leave any puddles. Two coats are required. The first coat may show some flash rusting, but the second coat will completely encapsulate all active oxidation. Spot priming is acceptable, but the applicator should be aware of the possibility of microscopic rust not visibly seen. Spot prime with two coats of METAL-PRIME RED-OX™ and extend one foot beyond the perimeter of the rust. Consideration should be given to two coat the entire surface area greatly reducing any possibility of future rust. Wait at least 12 hours before applying a second coat. Dry times will vary depending on weather. Apply the desired elastomeric roof coating of PERMAKOTE® Metal Roof Paint or PERMAGARD® Best Roof Coating
Airless Sprayers:
Use at least a 1 gallon per minute piston type airless sprayer with a minimum tip size of .027. Remove all line filters and gun filters before spraying.

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