502 RC-W Elasto-Kote
502 RC-W Elasto-Kote is a one component, fluid applied thermoplastic roofing system. It needs no intermixing, is easy to apply and results in surfaces of outstanding appearance and protection. RC-W provides a tough, flexible, elastic film that exhibits excellent color retention, weather resistance.
502 RC-W may be applied to concrete block, brick, concrete, stucco, steel, metal, wood, previously coated surfaces and most spray polyurethane roof surfaces. Do not apply over asphalt.
Proper surface preparation is important. All surfaces that 502 RC-W is to be applied must be clean, dry, free from ridges, sharp projections and other defects. Concrete decks must be cured for a minimum of 30 days. Patch and repair all cracks or holes with 502 Seam Sealer and Resat-Mat/Metal Seam Sealing Tape or appropriate sealants or caulking materials prior to application.
Apply Karnak 502 RC-W Self Priming Base Coat first at the rate of 1-1.5 gallons per 100 sq.ft. Allow base coat to dry 24 hours before applying 502 RC-W Elasto-Kote Finish at the rate of 1-1.5 gallons per 100 sq.ft. Apply both products by brush, roller or spray. Coverage may vary depending on the porosity and irregularity of the surface.
