Rated 5 out of 5 by from A must for shower installation This is the second time I have used this product and once again I am very pleased with it. The included instructions are clear and precise. A number of YouTube videos are also available which describe its application. Plenty of material is included in the pack to cover the two or three walls of a shower. It is easy to apply and is quick drying. I can thoroughly recommend this product.

Rated 5 out of 5 by from Walk in shower Used this product on my recent walk in shower. Easy to use and a great finish for peace of mind that no water will get to the plasterboard. Enough primer, coating and joint tape for 1800mm x 1000mm area. With a little left over to seal the floor around the splash areas.

Rated 2 out of 5 by from Not for shower trays If your planning on waterproofing a room this product is great, but simply put it doesnt stick to a new shower tray surface. I watched the video and did exactly the same as the man on the video, but when it came to tilling a few days later it had not stuck. So don't use as a shower tray seal as it wont work. Shower tray was a white smooth surface - new. gave 2 stars because it did seal the walls and corners, but slips straight of the shower tray.
