Product Review: Dicor 501LSW Self-Leveling Sealant

“Dicor 501LSW Self-Leveling Sealant is first in its’ class of lap sealant; wouldn’t have any other kind.”

RV Living Journey


A need for finding some sort of caulking for the roof occurred when a small leak had been noticed in the roof coming just under where the antenna sits on the roof. During a heavy storm one evening, a small drip was noticed slowly coming from a roof light. With the all the rain and wind, there was nothing to be done at the current moment. Once the elements subsided, the roof was able to be inspected. It appeared that the one who owned the RV beforehand had recently replaced the antenna, along with it, used a really weak caulking. Under the elements over the past few months, the caulking used to seal the antenna to the roof had withered away completely. Unsure of what caulking they had used, it was quite clear that it was weak.
