Thermoplastic polyolefin (TPO) is a single-ply roofing membrane commonly used on low-slope commercial roofs. TPO roof systems most commonly come in white and are mechanically fastened, self-adhered, or fully-adhered and welded at the seams.

Singly-ply TPO membranes can often be difficult for coatings to adhere to. When applied to a suitably cleaned, weathered TPO roof, Metacrylics TPO Primer and Metacrylics coatings provide optimal adhesion. TPO roofs that have leaking or deterioration issues due to ponding conditions and seam failures should be coated with Metacrylics. Metacrylics coatings withstand ponding conditions and resist debris, protecting the existing membrane from water infiltration.
