LLPT Butyl Seal Putty Tape | for Leak Proof RV Repair Window Glass Boat Sealing EPDM Roof Patching (BST343) | Black | 3MM Thick x 19MM Wide x 10M Long

Used this to repair a inner door lining on my car which wasn’t stuck down properly allowing a little water leak, easy to apply and stuck the lining down very well so fingers crossed no more leak.

I usually buy a mastic based sealant to seal my Motorhome roof windows, after a recommendation from a friend I looked at the Butyl strips as an alternative, the other 'Named' brands were a 5 meter roll for roughly the same cost as this item but this one has 10 meters on the roll so better value straight away. Still a bit sceptical, I installed the tape on the roof and Ohh my word, it sticks, I mean, it really sticks, when you use this you only get one chance to get it right, so be precise and certain you have everything lined up correctly. The window has been fitted and it has sealed perfectly, there was heavy rain that evening and there were no leaks at all. Highly recommend this tape and I certainly won't be going back to the mastics.

Easy to use doesn't set in the tube doesn't make a huge mess to clean up. Sticks very well. A great alternative to sickaflex on non load baring joins

Came in good condition and works perfect

Used to reseal the aluminium window frames to our GRP boat. Worked very well and now we don't have any leaks! Be careful not to let the putty contact anything else in the process as once it sticks to something else, it ends in a big mess!!! Also when dropping the frames back in, you only really get one chance - so make sure its aligned exactly. A big advantage is once the window frame is back in place, its water tight - no need to wait for it to cure like other sealants.

Worked well easy to use

Quality kit

Does the job, easy to use, would buy again. Fitted MaxAir Fan in roof of transit campervan, no signals of leaking or deteriorating.
