Mapei Shower Waterproofing Kit 4.5 5 16 16
Shower tanking... I wish I discovered this stuff before I bought an expensive shower tray and enclosure, because I would have gone for a wet room instead... The kit is a little on the expensive side and there are cheaper brands out there, which do exactly the same job. But being a tiler I'm familiar with 'Mapie' products. So essentially its the name I paid for... Maybe its like comparing a nike trainer to a hitech trainer. Ive not finished installing the shower yet. So I can't tell you how good it is. However it's definately worth tanking first. I've seen one too many bad examples of people just sticking tiles around a shower tray and blaming leaks on the sealant later... It's probably easier to apply the magnisium paste with a full size roller, as I used a 4" roller first and it went on a bit too thin. So I'll be giving it 3 coats... 12 Mar 2015
Waste of money Read the spiel, watched the video and decided I needed to use this expensive kit. Followed the video and instructions to the letter. When the tiler came to fix the tiles.....he noticed the Mapei film was starting to peel a bit....pulled at it lightly and it peeled off in sheets.....NOT STUCK. He had to scrape it off and start again with another product. 9 Mar 2015
Easy to use The kit comes with easy to follow instructions, and seems to do everything it claims. Have backed it up with Mapei adhesive and grout. 1 Mar 2015
Mapei Shower Waterproofing Kit I've just used this to tank 3 sides of a 760 x 2300mm shower cubicle in a small en-suite, . It's the first time i've used it and found it fairly easy to use after reading the instructions and watching the video. There was plenty of the tape and i've got about 1/3 left which i'll keep for later. My only small gripe is the price, it's a bit steep but after suffering with leaking showers in the past and seeing the damage it can cause then it makes the cost a little less painful. Overall worth it for the peace of mind and i'll be using it again on my other shower and bath in the near future. 22 Nov 2014
