Review on Dicor (522TPO-450-1C White 4&#34 by Jason Hayes

A branch tore a small hole in our TPO roof. This patch fixed it perfectly. I also used Dicor's Self Leveling Lap Sealant to coat the edges to make it fully weatherproof. The patch was easy to use. Be sure to clean the area before applying the patch and place it exactly where it should be the first time. Care must be taken to ensure that no air bubbles remain.
