GlennWest Posted April 12 Report Share Posted April 12 I have posted before on here about one door leaking to front storage area. I have caulked, pulled outside trim and thought I had found problem. Well noticed rotted wood around frame of door so I removed the door today there was no sealant ever put inside door to opening. Well removed all damaged wood and replaced with good. Right much damage. Should I caulk inside of door frame or use butyl rubber? Quote Link to comment Share on other sites More sharing options...
GlennWest Posted April 12 Author Report Share Posted April 12 Well checked it out on youtube and keystone and Lippert has videos of this. Used butyl rubber on seal surface and then silicone the outside. Mine only had outside silicone for sealing. Quote Link to comment Share on other sites More sharing options...

GlennWest Posted April 13 Author Report Share Posted April 13 (edited) yes. Rebuilding that door frame was quite a job. Had to cut down 2X4's to fit in there. Could have bought some 2" boards Edited April 13 by GlennWest Quote Link to comment Share on other sites More sharing options...

Ray,IN Posted April 15 Report Share Posted April 15 I've never liked using silicone on an RV, seems it never adheres well long-term. There is a reason it is the cheapest sealant on the shelf at stores. Quote Link to comment Share on other sites More sharing options...

My local Lowes has DAP Latex caulk for $2.62/tube whereas the GE Silicon is $11.98/tube. Quote Link to comment Share on other sites More sharing options...
Jaydrvr Posted April 15 Report Share Posted April 15 Good silicone is not cheap and it works very well the first time it's used. You can get cheap versions of silicone, but it's watered down junk and shouldn't be expected to perform at the same level. There are better choices for boat and RV repair, such as 3M 5200, etc. Jay Quote Link to comment Share on other sites More sharing options...
RV_ Posted April 15 Report Share Posted April 15 Silicone will not adhere to "rubber roofs or EPDM." For roofs Butyl rubber caulk tape first between roof and flange of vent, pipe, A/C, or skylight. Then self leveling caulk over the top for more strength and UV protection For Windows I found best to use butyl rubber caulk and Parr Bond along the top and radius' then stop. Parr bond stays flexible but does yellow over time. However it can be removed later with a plastic scraper. If the window has a foam gasket order one for it. On items silicone does stick to it is forever. If applied incorrectly and not smoothly it can cause leaks because you can't tell where the pin sized holes are. Always check the manufacturers websites like Dicor, one of the leading manufacturers of EPDM and TPM RV roofing membranes, and your RV manufacturer if you are not sure. I have found dealerships that had bad advice and repairs and great advice and repairs. Source: https://dicorproducts.com/wp-content/uploads/sites/2/2020/08/BRITEPLY_RETROFIT_install-guide.pdf Never use silicone as a sealant on an RV roof mage of EPDM or TPO materials. However, in other areas like where the manufacturer used it other than the roofs this little video will help you pick the right one for your job other than on the roof. If you are going to roll a sealant over the whole roof go to the Dicor rubber roof manufacturing website site for that. https://dicorproducts.com/resourcesrudys/ Quote Link to comment Share on other sites More sharing options...
