Rated 5 out of 5 by from Quick and easy to apply An excellent product that could save you many times it's cost by avoiding water ingress into plasterboard backing. Much easier than replacing plaster board with cement based backer boards. However if starting from scratch I'd always consider lining around showers with cement based boards.

Rated 5 out of 5 by from Very good waterproofing kit Bought this kit recently for waterproofing my new shower. Applied to two adjacent walls and the ply floor. Two applications are enough to form a layer. Since the tiles will cover the waterproofing layer, it is easy to apply using a brush than a roller to create some rough textures on the surface to provide more grips. I would recommend this for any new shower

Rated 5 out of 5 by from Shower waterproofing Used this to waterproof a shower. It was cheaper using this kit to normal plasterboard than using hardiebacker boards. Well enough in the kit. Would have liked a bit more tape as i needed to do three walls in a walk in shower. Got around half a tub of the paint on stuff after two good coats. Time will tell how good it is but looks like it will work perfect.
