Can I use household caulk around RV windows?

Interesting comments here. I'm pretty sure Dicor makes a product for the "side" of your RV too. Not just the self leveling stuff.

My travel trailer came from the factory with caulk over the tops and sides of the windows, door & corners in addition to the butyl tape that was used during assembly. On top of that, when it went in for factory work, they caulked it again.

I personally won't use a silicone product. I've had troubles with them staying stuck and of course nothing else will stick after that either.

If you're replacing the whole window frame, I would use urethane sealant, readily available at Home depot. Not as good for caulking around a window that's already in place, but best choice when re-installing a window unit.

Yes.

Use Dicor made for RV caulk. Silicone will not work.

Dicor is good for sealing stuff on roofs. It will self level. It is not good for sides of Rv's as it will flow down the side.

They make a Dicor calk just for sealing that is not self level and stay a bead. Quote: 551 LSW non-leveling/non-sag lap sealant formulated for 1/4 and 3/8 bead. The best way is to take the window out and use the putty RV tape you can buy at dealers, what the mfg uses.

I had a clearance light leak over a year ago and didnt have Dicor. I used some latex window calk around them. Just checked it the other day and still holding strong.

I went through this on my 5'er. There should be Butyl tape that is between the exterior side where it mates up to the exterior wall on the RV. There is 2 kinds of Dicor, self leveling which you do not want, it will run down the sides. You want to use Dicor Non-Sag Lap Sealent. The non-sag will not run down the side and you can use it on the top of the window just as the others are sealed with it.
