- Usage
To bridge wider gaps, AcryCaulk can be used in conjunction with non-woven polyester roofing cloth. Apply only to clean, dry substrates at temperatures in excess of 45°F. Do not use when rain is imminent. Cured AcryCaulk has excellent resistance to hydrocarbon environments, acids, bases, and industrial pollutants.
- Coating System Detailing
Can be applied to all penetrations, voids, openings and seams (metal roofs). Clean surface and remove all loose debris. Apply with brush or trowel. Fully embed fabric into AcryCaulk. Saturate and seal fabric with AcryCaulk extending beyond the fabric by a minimum of 2 inches.
- Application
Approximate spread rates for different applications of AcryCaulk on metal roofs:
- Application rate for vertical seams is approximately 1/3 gallon per 100 lineal feet to “force-feed” an approximate 1” wide line of the caulk into the narrow gap. Or, about 1/10 gallon of AcryCaulk per 100 square feet of roof surface to be coated.
- All horizontal and ridge cap seams, as well as large holes and gaps, shall be sealed with 4” polyester cloth embedded between two coats AcryCaulk sealant. The spread rate for this 6” wide line of caulk/fabric/caulk is approximately 4 gallons of AcryCaulk per 100 lineal feet. Or, approximately 1/4 to 1/2 gallon of caulk per 100 square feet of roof surface to be coated.
Fastener heads, as well as small holes and gaps, may be bridged with AcryCaulk without the use of polyester cloth. The application rate for this procedure is approximately 1/8 gallon per 100 square feet of roof surface to be coated.

Safety & Health
- Precautions
- Optimum application window is when ambient temperature is above 45°F and relative humidity is below 85%.
- Do not apply to wet surfaces or when inclement weather is present.
- Do not apply when gross ponded water is present, the existing roofing system is suspected of holding moisture or the roof area does not shed water effectively.
Storage & Handling
- Maintenance
Damaged areas should be cleaned and free of loose debris. Apply with brush or trowel over area to be sealed and repaired. Fully embed fabric into AcryCaulk. Saturate and seal fabric with AcryCaulk extending beyond the fabric by a minimum of 2 inches.
