Easy to use I only needed mapegum, which was difficult to get hold of quickly on its own. I used waterproof foam board for the wall, which has its own tape system, so didn't use tape that came with product for that. I wanted a belt and braces approach and Mapegum is excellent for waterproofing. Very easy to apply with a brush and goes a long way. I was only going to do the seams and the screw holes but managed to do all of the wall along the bath. Still have a bit left! Used the tape for waterproofing the wall to the floor without a problem. Didn't have to use the primer... so if someone wants some... 9 May 2015

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
