Mapei Shower Waterproofing Kit is rated 4.6 out of 5 by 53.
Rated 3 out of 5 by from Not sure about this Product I bought 2 of these kits for shower and Bath areas. I'm happy with the coating being waterproof, however, I followed the instructions to the Letter, but the Mapegum coating that was painted over the rubber part of the tape seemed to take a very long time to dry. On the walls it was dry in 1-2 hours, but on the tape it was still tacky after 12 hours and I had to leave for 24 hours until completely dried before recoating the corners. I was Tanking the areas down to the floor before fitting shower tray, so now I'm left with the decision, do I use the tape between wall and shower tray as per instructions, or buy another product to seal this area. I'm' just not convinced that the tape will stick long term It would also be a lot better if the Tape was self stick instead of having to use the Mapegum paste to stick it in. Noot sure I would use this again

Rated 5 out of 5 by from Easy to use Really easy to use. I was surprised the tape for corners wasn't self adhesive,instead you put the gum on the wall, then the tape, then the gum pastes over the top. Not sure if that's better or worse, but was relatively easy. Hoping it will last the test of time!

Rated 5 out of 5 by from Easy to use First time I've used it, but it was easy to apply and easily covered the shower/ bath space I needed. Easy clean up if tackled when wet. Would certainly use again.

Rated 1 out of 5 by from Badly packaged Good product but they only half fill the primer bottle. So insufficient for a normal showers walls. So the kit is incomplete. Unable to buy the primer separately.
