I just picked up a 311bhs last week.
How to glue loose rubber rv roof.
Spread the sealer all over the area that needs a patch lay a piece of fiber glass tape over the patch cover it with more sealer.
The glue most commonly used to adhere an epdm rubber roof to the wood substrate does not do a good job of adhering the membrane to aluminum.
Just as above with the construction adhesive jb weld kwik weld epoxy can be a very useful glue to have on hand for all the small day to day rv repairs that come up while living or traveling in a camper.
The liquid rubber would adhere to the wood roof and chemically bond to the original rubber roof for a seamless repair.
It s also loose on the edge where it folds over down the sidewall.
Use a roller to smooth the surface and remove any new air bubbles.
It particularly comes in handy when you need to repair something that requires a faster set time whether it s your plastic rv door handle rv refrigerator shelves your kid s toys or the.
To do that you would just cut out the loose section of the rubber and paint on the liquid rubber.
For instance you can see a bubble like shoe prints where i ve walked on the roof.
Once the glue is down restretch and staple the edge of the membrane and reinstall the trim with new sealants and screws as needed.
Weight the patch until it s dry.
I had a tear in my roof when i bought it and just patched it this way.
Then you can put the eternabond on.
Its easy to do.
I noticed that the tpo looks loose as if it isn t glued to the roof in the middle and on the edges.
Fiberglass this type of rv roof is hard to the touch and is a bit more rare than a rubber rv roof because the material adds cost and weight to the rv.
Having said that fiberglass rv roofs require less maintenance than rubber rv roofs which makes them preferable for some campers.
If the bubble is small and just along the edge of the trim then i wouldn t worry about it much.
It s critical to thoroughly clean the area you re patching so the adhesive will bond with the roof.
I now have found a new problem the roof top layer has come unglued all that is holding it on is the ac s vents and side molding.
The glue actually soaks into the wood and bonds to the rubber so it is unable to form that same bond on the side rolls.
This is my first rig with a tpo roof.
Is this all normal.
