- Recommended Uses
- RC 1800 was specifically developed as a protective coating for EPDM, TPO, PVC, modified bitumen, and smooth BUR.
- With excellent adhesion and durability, RC 1800 is proven to provide excellent UV protection and long term durability for spray polyurethane foam.
- Application Instructions
- RC 1800 may be applied by medium nap rollers, soft brushes or high-pressure airless spray equipment.
- Apply RC 1800 only to clean, dry, sound surfaces free of loose particles or other foreign matter.
- For best results, ambient temperature should be between 50 - 90 °F.
- Higher temperatures will shorten the cure time and working time for proper application of granules before the material has skinned.
- Lower temperatures will lengthen the skin over, tack-free and ultimate cure time.
- Sudden temperature declines may also result in dew formation on surfaces, which can prevent adhesion development.
- For best results, relative humidity should be above 20%.
- Lower humidity will slow the cure time significantly.
- Apply RC 1800 at the rate of 1.25 gallons per 100 sq. ft.
- Minimum dry mil thickness shall be above 20 mils.
- Two passes of silicone and a primer coat may be required for some applications and warranty programs.
- Product application should be suspended immediately and our technical service personnel contacted if the results being obtained are less than desirable.
- Limitations & Precautions
- Avoid moisture contamination in sealed containers.
- Store away from heat and sources of ignition.
- Do not inhale vapor or mist; do not get on skin, in eyes or on clothing.
