Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose ASC 1 when you want a white, CRRC-rated reflective topcoat to reduce roof temperature and extend roof life on asphalt or metal. Pressure wash for best results and sweep all standing water before coating; apply in the morning on a warm, sunny day for maximum cure time. Do not thin the product, do not apply when rain or heavy dew is expected within 24 hours, and do not store below 50°F or above 120°F.
For exterior use only; wear protective clothing and eyewear, use adequate ventilation, and read the Material Safety Data Sheet before handling, as the product is an eye, skin and respiratory irritant.
