Can I apply Pancrete over foam-lined condensate pans?
Many condensate pans were manufactured with foam sprayed on the bottom of the pans. The intent was to provide insulation to the pan, to help keep it from sweating on its underside. Over the years, these pan types like others have become corroded and in need of replacement. Pancrete can be poured over a foam lining if necessary. Ideally the foam should be removed if possible and the metal surfaces abraded. If the user cannot do this, then he should clean up the surface of the foam as much as possible. Wet-vac out any debris, and let the foam dry by turning off the air handler and waiting, or by using a blower. The applicator would then do a standard 1/4 inch pour of Pancrete. Because foam contains air holes or pockets within it, as do all foam like materials, the Pancrete will travel down into the foam and into the pockets, displacing air. Air bubbles may rise to the surface. The bubbles may not all be released before the Pancrete gets hard. In this case, you will find the surface to be
