            Can the butyl tape be used in a pool?

            Answer This Question

            Hi Davis, That depends on the application. For areas without lots of flowing water it should be suitable. For areas with flowing water, I would refrain from use butyl tape as a solution as the rushing water can cause it to peel.

                  Works pretty good. Much thinner than some more heavy duty Butyl tapes out there. Does the job waterproofing your sheet metal roofing.
                  by
                  Inadequate for RV windows. This Butyl tape was thinner and narrower than any other Butyl tape we’ve purchased. I used 3 layers of it around our RV window and barely had any squeeze out. Will probably have to redo it, for a water tight seal.

                  Horrible
                  Impossible to unroll from the smashed roll. All the ones in the stor were like this. Horrible to try to use as it stretched away from the backing before applying. Never buy again!

                    Used this tape to reseal the vapor barrier on my car doors, after replacing the window regulator. It is easy to apply and appear to stick where you want it to stick. No mess, no fuss.
                    by
                    Would be adequate if it were one in wide and twice as thick. Forced to double it up to be sufficient.

                    Worked great for our fountain. Wrapped around the piping in between the layers of the fountain.
