Expert Verdict — Reviewed by the SuperArbor Pro Desk
Two-coat Elasto-Kote systems work best when the base coat is applied at the specified rate and fully cured before the reflective finish goes on, so schedule the finish coat for the same weather window. In warm climates the reflective gray surface reduces roof surface temperatures versus bare bitumen. Keep both coats out of standing water until cured and confirm substrate compatibility, especially on younger single-ply roofs.
Apply in suitable weather with proper ventilation and personal protective equipment per the coating label directions.
