Dicor launches roof care video series

(Oct. 19, 2012) -- Two initial videos feature well-known RV educator Mark Polk. In one, he walks through the steps for effectively using Dicor Products’ lap sealant to seal cracks and deterioration in existing roof seals. In another, Polk shows simple ways to determine whether an RV is covered by an EPDM membrane or TPO material, which is important in determining the kind of sealant to use.
