- Recommended Uses
- RC 1975 was specifically developed as a protective coating (base and finish coat) for sprayed-in-place polyurethane foam roofing.
- With excellent adhesion, RC 1975 may be used as a base coat for protection of conventional commercial/industrial surfaces such as, but not limited to: TPO and EPDM single-ply membranes, Mod. Bit., smooth BUR and the lining and sealing of interior gutter systems.
- General Surface Preperation and Application Instructions
- RC 1975 may be applied by medium nap rollers, soft brushes or conventional airless spray equipment.
- Apply RC 1900 only to clean, dry, sound coating surfaces free of loose particles or other foreign matter.
- Successive and/or topcoats must be applied to the base or intermediate coats within 48 hours to ensure proper adhesion.
- Apply RC 1975 at the rate of 1.25 gallons per 100 sq. ft. per coat.
- Minimum dry mil thickness shall be 12.5 DFT for the base coat and 12.5 DFT for the top coat.
- Do not apply if the ambient temperature falls below 50°F.
- Product application should be suspended immediately and our technical service personnel contacted if the results being obtained are less than desirable.
