dddlin Report post Posted November 7, 2016 We need to have the rubber roof recaulked and are trying to find how this is done. Apply over the old after cleaning, or what? Share this post Link to post Share on other sites
jleamont Report post Posted November 7, 2016 dddlin, what area are you planning on repairing? The reason I ask is if it were a seam I would use the tape rather than the Dicor lap sealant. Here is a link to the tape https://www.amazon.com/s/?ie=UTF8&keywords=rv+tape+eternabond&tag=googhydr-20&index=aps&hvadid=153683479395&hvpos=1t1&hvnetw=g&hvrand=7686784629803387707&hvpone=&hvptwo=&hvqmt=b&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9007366&hvtargid=kwd-131762088733&ref=pd_sl_e5jmukv0c_b If you are sealing around roof openings i.e. vents I clean off any excess with a putty knife, just be sure to be careful of the roof itself and re apply the lap sealant.

manholt Report post Posted November 8, 2016 It would be helpful to know what year, make and model coach you have. Also, what type off roof. Carl Share this post Link to post Share on other sites
kaypsmith Report post Posted November 8, 2016 If the old caulking has any scale and cracks, I would remove any loose from those areas and clean thoroughly before recaulking. Share this post Link to post Share on other sites
manholt Report post Posted November 8, 2016 You can also Google RV roof sealant, repair or caulking...lot's off links to DIY or how to clean and prep, depending on the type off roof you have, rubber, aluminum, fiberglass, etc. Carl Share this post Link to post Share on other sites
