Nassboards Waterproof Tanking Tape - Aqua Elastic Self Adhesive Butyl Joining Permanent Strong Sealing Tape for Waterproofing Bathrooms, Shower Wet Rooms, for Use Outdoors Indoors Preventing Leaks 5m

Easy to work with. Good for all round repairs.

So strong adhesion, great to have but a pain to apply, once stuck virtually impossible to reposition! Great for the function but take great care with removing backing paper otherwise the adhesion gets you! A two person job if length is more than 30cm (or grow a third arm!) All in all a great product

This stuff is very sticky if you've not used it before like me then it takes some getting used to I found best to apply in two halves it comes like this anyway but I found by folding it down the center and applying one half then the over follows but get it wrong then it's hard to correct try not to stretch it as this will throw out how it lays by its very nature it is hopefully waterproof but time will tell.

Used this on boards in my bathroom. Seems to work well and has helped with the tanking

Happy with this purchase - easy to use and clear insurrections. Got us through our bathroom renovation!

Good for intended purchase however not dissimilar in price or performance to other brands, delivery was quick.

The roller head kept coming off and not very good adhesion

Good stuff, very sticky... get it right first time!
