PERMAPATCH-NYLON™

PERMAPATCH™-N can be used on horizontal (non-ponding) and vertical surfaces or substrates including roofs, walls, floors, etc. Excellent adhesion on weathered wood, shakes, plywood, clapboard, primed metal, galvanized, aluminum, tin, copper, asbestos, asphalt, urethane, polyester, primed styrofoam, 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.
PERMAPATCH™-N is ideal for residential, commercial and industrial applications.

SURFACE PREPARATION:
Apply only to a sound, completely dry, well prepared surface. Leaks must be repaired before any coating is applied. If primer was applied, it is essential that the primer surface is clean and 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. PERMAPATCH™-N will resist mildew growth, but will not kill mildew already on the surface.

Metal:
Clean surface of all grease, oil and foreign matter before patching. 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 PERMAPATCH™-N 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, galvanized or coated metal must be lightly scuffed without penetrating the coated finish or galvanizing. If applicable, use METAL-PRIME RED-OX™ to spot prime the penetrated area(s).

APPLICATION PROCEDURE:
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 caulk will be subjected to rain or heavy dew before it has had enough time to dry (approximately 4 to 6 hours). Drying time will vary depending on temperature, humidity and location.
Apply using a stiff brush or trowel. Patch any holes, cracks, flashings, valleys, vents, etc. and any low spots or vulnerable leaking areas. (PERMAPATCH™-N will seal seams, but for severe applications inquire about PERMATAPE™, a polyester seam tape.) Spread uniformly. When filling deep holes, more than 1 square inch, apply multiple coats and build the patch up and allow for minimal shrinkage. Sets to touch in approximately 2 hours and dries in approximately 5 to 24 hours depending on thickness of application. The thicker the PERMAPATCH™-N is applied the longer it will take to dry. PERMAPATCH™-N can be coated over in 12 hours, but be careful not to disturb the patch since it will dry from top to bottom. PERMAPATCH™-N should be top coated with a compatible latex paint or coating and should not be left uncoated.
