Any roof can be painted with one of Hy-Tech Roof Coatings, asphalt shingles, rubber, built up, cement tile, metal...Any Roof Surface.
Flat roofs which are prone to ponding water must be coated with either "Roof Guard" or "Perma Kote". All roofs require one coat of primer and two coats of the finish product. After this initial application maintenance is easy and inexpensive. In 8-10 years you simply wash the roof and apply One Coat of the finish.
SURFACE PREPARATION: Scrape off all loose, peeling, blistering, chipping, cracking or flaking coating. Wire brushing, pressure cleaning, power sanding or sandblasting may be used to remove powdering and chalking coating. To remove dirt, grease, etc., wash with water and detergent and then rinse thoroughly with clean water. To remove mildew, fungus, etc., scrub with Hy-Tech House Wash or a solution made with 16 fluid ounces (473 mL) of liquid household bleach and 2 fluid ounces (59 mL) of detergent in one gallon (3.785 L) of water. Rinse thoroughly with clean water. Patch all cracks and seams. You should have a completely clean and firm surface before any new coating is applied.
Make any necessary repairs or replacements to damaged or leaking roof materials.
Avoid using cleaners with built-in wax or silicon additives since this may affect coating bond.
CAUTION!!! Look out for these trouble spots:
Flashings: All flashings should fit tightly to the roof. They should be held firmly by screws or taped down.
Damaged or rusty moldings and flashings should be repaired, or removed and replaced.
Stacks and Vents: Stacks and vents remove excess moisture and fumes from your home. Faulty or poor performing stacks or vents will allow moisture to accumulate between the ceiling and the roof and cause condensation. They should be repaired or replaced, or added, if necessary.
Seams, Cracks, and Stress Areas: The same repair procedure generally applies to seams, cracks, and stress areas. Remove all dried-out caulk or coating. On seams, tighten screws if necessary. Seams, cracks, and stress areas over 1/4" wide should be repaired using our polyester seam patching tape. Always put tape over the entire seam - not just the portion that looks faulty, seal tape in by feathering Elasto Patch over tape.
Ponding Water: Any area of a roof where water may pond must be repaired by installing drains, polyurethane foam build-up, or any means necessary to remove and prevent ponding water.
PRIMING:
NEW METAL SURFACES: Prime with one coat #15 Aqua Prime
RUSTY METAL: Prime with #18 Red Oxide Metal Primer
ALL OTHER SURFACES: One coat of Hy-Tech #20 Bond-It primer must be applied, according to directions, before applying any of the Hy-Tech Finish Roof Coatings.
APPLICATION: Apply only at temperatures above 50° F. (10° C). Stir thoroughly before using and occasionally while using. May be applied to dry or slightly damp surfaces, using brush, roller or spray. Apply generously, working the Coating into pores and cracks. Try to apply the Coating as smoothly as possible. A minimum of two coats is recommended. Two thin coats are always preferable to one thick coat.
THINNING: Hy-Tech Roof Coatings are ready to use and should be applied full strength as they are received in the can. Any thinning of the Coating will reduce the percentage of solids, which will adversely affect the durability of the applied coating.
COVERAGE: On a rough porous surface, such as concrete tile, one gallon will usually cover from 75 to 100 sq.ft. On porous surfaces, the coverage on the second coat normally will be greater than the first coat. On smooth, non-porous surfaces, such as sheet metal, the coverage rate will be 200-250 sq.ft. per gallon. Primers cover 175-200 sq. ft. per gallon.
DRYING TIME: Drying time will vary depending on surface and air temperature, humidity, wind or air movement, exposure to sunlight, etc. Under ideal drying conditions, Hy-Tech Roof Coatings form a dew and drizzle resistant film in approx. 30 to 60 minutes after application, and dries sufficiently in approx. three or four hours to permit the application of a second coat. A longer drying time will be required if the surface being coated is not completely dry, is colder than 50 ° F., if too thick a coat is applied, if the relative humidity is higher than 90%, if the air is calm, or the surface is not exposed to direct sunlight.
CLEAN UP: Any drips, splatters, overspray or spills on shrubbery, walkways, drive-ways, or sides of mobile homes must be cleaned up immediately before Coating dries. NOTE: If Coating is spilled or splashed remove it at once, using water from a hose, warm soapy water, or alcohol solvent. Coating not removed before it dries will be almost impossible to remove. Clean hands, brushes, rollers, tools and other equipment immediately after use in warm, soapy water.
WEATHER CONSIDERATION: Before application, KEEP FROM FREEZING. Apply only at temperatures above 50° F. Apply only when weather will be fair for a sufficiently long time for the Coating to dry. Do not apply late in the afternoon or early evening when a heavy dew could develop on the coating surface before it dries thoroughly. A very heavy rainstorm, such as those common in tropical climates, could wash the Coating off during the first few hours after application, if it has not dried thoroughly.
