Re sealing seams with Dicor.

[cm2785]

Hey guys I brought my rig to the local RV repair guy who is a second generation RV repair guy and has 5 star reviews and is absolutely packed all the time.. he resealed my whole roof, putting new lap sealant on all the seams. I’m new to this but I asked him the procedure and he said he cleans the area with just water and let’s it dry and applies the Dicor. He said it stuck very well. I was under the impression you were to clean it with alcohol? He’s just adding the sealant to the already white coated roof so maybe that’s okay, but I wanted to ask you guys as I am absolutely paranoid about leaks. Thanks!

Dicor is a great product and his procedure will hold up just fine

Alcohol (or mineral spirits) is a good solvent when there is sticky residue or other substances on the surface, but usually it's just plain old dirt and washing it away is all that is required. If its becomes necessary to remove some of the old lap sealant, then some sort of solvent is used, but not if just touching up existing stuff.

If this guy has a solid rep, trust his judgment.

I'm paranoid also. After using Dicor, I put Eternabond on all my roof seams (edges, skylight, etc.) and wherever I could. A little water can do alot of damage in a short period of time.
