Why United Coatings™ Diathon® HT Roof Coating?

United Coatings™ Diathon® HT Roof Coating has the ability to uniformly cover the profile of textured substrates. Its dense, tight finish helps repel dirt and pollutants while the elastomeric membrane remains permanently flexible. This "breathable" coating allows moisture vapor to pass through the film while remaining impervious to mass water penetration.


Diathon® HT Roof Coating can be used to help protect sprayed-in-place polyurethane foam on new or existing roofs as well as heated or ambient storage tanks. It also achieves excellent adhesion over concrete, masonry, primed metal, primed wood, and asphaltic surfaces.
