- Surface Preparation
- RC 1650 should be applied only to clean, dry, sound surfaces free of loose particles or other foreign matter.
- Over metal surfaces that show signs of oxidation, rust should be removed by wire brushing if necessary after pressure washing.
- A primer is required over such areas, as well as over areas that may have existing caulking.
- Application Instructions
- RC 1650 may be applied by brushing or troweling.
- RST Seam Tape or RPM Polyester Mesh is recommended over cracks or bridges that exceed 1/16”.
- Apply at a rate of 50 wet mils maximum.
- Application should be suspended immediately and our technical service personnel contacted if the results being obtained are less than desirable.
- Coverage Rates
Approx. 300 fasteners per gallon; 85 linear feet of seams at 4” wide.
- Limitations & Precautions
- RC 1650 is a water-based acrylic seam compound that will freeze and become unusable at temperatures below 32ºF.
- Protect from freezing during shipment and storage.
- Do not store material at temperatures below 45ºF.
- Do not apply RC 1650 at temperatures below 50ºF or of there is a chance of temperatures falling below 32ºF within a 24-hour period.
- Do not apply RC 1650 over wet substrates or when inclement weather is imminent.
