Expert Verdict — Reviewed by the SuperArbor Pro Desk

Base coats like 294 seal and level the roof field before the reflective top coat goes on, so spend time on substrate prep, priming and seam reinforcement per the system specification. Apply at the specified spread rate and allow proper cure time between coats. Two gallons per square is a typical order-of-magnitude check, but always confirm against the data sheet for your substrate.

Wear gloves and eye protection and ensure adequate ventilation during application; review the safety data sheet before use.


Order the Henry Pro-Grade 294 Base Coat and Sealer 5 gallon pail in Grey for your roof restoration system.
