By Damplas Product code: 20591 Pack size: Each

Product Details

Looking for a practical and cost-effective way to damp proof your loft conversion or basement refit using butyl tape? Try this double-sided one from Damplas. 

The tape uses a high-quality adhesive that bonds firmly to damp-proof materials or membranes. This means you can count on it to stick in areas with high amounts of moisture in the air, such as bathrooms, attics or basements.

There's also no chance of moisture seeping through your walls or floor and causing damage, as the butyl material is totally damp proof. It's supplied on a roll, so it's easy to use too. All you need to do is overlap your membrane material by a minimum of 150 mm and then apply the tape in between the two layers. Once you're done, apply a length of Damplas single-sided jointing tape to seal up the overlap.

• A high performance butyl mastic tape

• Used for joining damp proof and DPM

• Adhesive on both sides

• Methane gas resistant (tested to ISO15015-1, achieves 0.07 ml/ linear metre/day)

• BBA-approved

Reviews
Radon/DPM Double Sided Butyl Jointing Tape 50mm x 10m is rated 4.7 out of 5 by 31.
Rated 5 out of 5 by from High Quality Reliable Double Sided Butyl Tape High quality double sided butyl tape that was very effective in creating a strong waterproof seal between my box profile roofing sheets. Very tacky once the backing tape removed so you need to ensure you're fully ready and in a position to place the tape without the need to reposition it or the pieces you're joining together.

Rated 5 out of 5 by from Worked great to repair a fish pond - and more reasonable price Works as described. I needed some double sided joining tape to repair some cracks and holes in a PVC goldfish pond liner. the usual sources via eBay are a bit pricey esp as I needed quite a bit to make sure I got all the leaks. I wasn't sure if this would as well, but in fact it really does work well for the task. I forgot that it is blue! (usually its black) However it actually looks nice and it has certainly done the trick and I have a lot left over for when next needed. It works best if the material it is glued to is dry and clean. A slight roughing with fine/medium sandpaper helps then it really does stick well. A week or so later its all looking fine and I am really pleased to have found this.

Rated 3 out of 5 by from Not the easiest... Does the job very well but the backing paper is extremely tricky to remove. You know how difficult it can be peeling off the backing from ordinary double-sided tape? Well this is much worse. Even leaving a little bit of paper overhanging in order to get a good grip of it just resulted in fingernails sticking to the butyl. Takes a lot of practice and patience.
