Expert Verdict — Reviewed by the SuperArbor Pro Desk
For restorations over aged BUR or mod-bit, clean thoroughly and repair splits before coating, then apply SMARTCOAT 401 at the manufacturer's specified rate. Use white where cooling savings matter most; Reflective Tan or Light Gray where aesthetics or visible roofs call for it. Choose the 5 gallon pail for small patches and the 55 or 275 gallon containers for full-field recoats.
Wear appropriate personal protective equipment and follow rooftop fall protection practices when applying roof coatings.
Order CertainTeed SMARTCOAT 401 High Solids Acrylic Coating in the 5 gallon white pail for your next restoration.
