PERMAKOTE® SILVER SEAL has excellent adhesion on most any interior or exterior surfaces including: weathered wood, shakes, plywood, primed metal, clapboard, galvanized, aluminum, tin, copper, asbestos, asphalt, urethane, polyester, primed styrofoam, primed fiberglass, built-up-roofs, bonded roof gravel, rolled roofing, modified bitumen membranes, mineral surfaced roofing, concrete tiles, clay tiles, masonry tiles (flat or barrel), primed synthetic or aluminum, adobe, slate, slab, properly prepared EPDM, and various other substrates.
PERMAKOTE® SILVER SEAL is ideal for residential, commercial and industrial applications.
Roofs: Recommended for well draining, SLOPED roofing surfaces only (see Warranty Compliance Information Section Below).

SURFACE PREPARATION:
Apply only to a sound, completely dry, well prepared roof surface. Leaks must be repaired before any coating is applied. If primer was applied, it is essential that the primed surface is clean, dry and free of all moisture. If no primer was 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. PERMAKOTE® SILVER SEAL will resist mildew growth, but will not kill mildew already on the surface. Clean Interior Surfaces by washing off all dirt, grease, soap and oil build-up with a powdered household cleaner and water. Rinse thoroughly. Remove loose paint and powdery substances. If, after cleaning, there is still chalk present or existing coating is compromised, use PERMABOND™ Bonding Primer for Roofs or ULTRA PRIME™ Stucco Primer for walls and most other surfaces. Patch any holes, cracks, flashings, valleys, vents, etc., with PERMAPATCH™ Elastomeric Patching Compound, a Waterproofing Caulk and Sealant. Tape & seal all seams with PERMATAPE™, a Polyester Fabric Tape or PERMASTIK™ Butyl Tape.

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 PERMAKOTE® SILVER SEAL 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™ Rusted Metal Primer Sealer to spot prime the penetrated areas.

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 coating uniformly. Spread Rate will vary depending on surface. Apply each coat between 10 to 14 mils wet film thickness. Wait at least 12 hours before applying a second coat. Two coats, resulting in a minimum 12 mil total dry film thickness, are required for the 10 YEAR LIMITED MATERIAL WARRANTY.

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