Surface Preparation, Application & Coverage in 6 Easy Steps

  • Step 1: Pressure Wash, Sweep and Remove All Surface Contaminates

To maximize adhesion and coverage, the surface should be clean and free of any debris.

  • Step 2: Allow Surface to Dry (1-4 hours depending on weather)

Allow the recently cleaned surface to dry completely before applying your first coat.

  • Step 3: Repair Cracks or Other Damaged Areas

Identify and repair any seams or cracks. Use fiberglass or a fiber mesh mat.

  • Step 4: Apply Initial Coat Roof Coating (100 to 200 sq. ft. per gallon)

Use a professional roll (or brush for smaller jobs) to apply a generous coat onto your surface.

  • Step 5: Allow Surface to Dry (24-48 hours depending on weather)

Weather permitting, you should allow your first coat to dry for at least 24 hours.
