Removing Butyl Tape From Roof

You position the end of the roll over the join that you intend sealing and roll the tape off to your required length.

Removing butyl tape from roof. Pull the tape up slowly and get as much adhesive as you can while removing. Must the surface be dust free and clean. The butyl tape is not tape for this application it comes in a pump can and is applied much like caulk in a caulking gun but can reach into much smaller recesses and is pumped into and behind the rubber channel edges both on the glass and body sides. Not all new dicor lap sealant products work with every roof cleaner or sealant removal.

I use a very thin blade metal scraper purchased from lowe s round the corner on the scraper to about a 1 8 radius bend the blade about 1 from the end to about a 10 deg. One of the things about removing old sealant is the type of sealant cleaner you use. Mix hot water with a squirt of liquid dish soap. Soak a rag or cloth in the water and then set the cloth on the tape to saturate tape that becomes stuck and you cannot remove.

Yup this is what i did. Scrap up the surface tape with a putty knife. One such brand is epdm roof cleaner. Lay the end of the scraper flat against the epdm rubber roof and proceed to work the handle back and forth.

Continue to lift up on the tape with the putty knife razor blade or scraper until all of the tape is loose so you can remove it. This cleaner even if left to dry may react with the new sealant and cause your rv s roof to bubble. Sometimes can warm up the sticky stuff and roll push with fingertips kinda hard on the fingers depends on how sticky the original butyl tape is. Step 2 cover the remaining adhesive with adhesive remover or paint thinner such as toulene.

Hair dryer to warm up and rolled it off.
