Rated 5 out of 5 by from Goes far! Goes on nicely with a masonry brush, but expect to put it on quickly to avoid setting in your bucket. I decanted 1/5 of the tanking slurry into a bucket before mixing in water by hand, however that only gave me approximately 20 minutes before it began to really thicken and need pasting on rather than painting on. With the next lot, I mixed with a drill mixer attachment which gave me more time to then apply the slurry. I wouldn’t make up the whole batch at once as I’d fully expect lots of it to set before you get a chance to get it on the wall. 1/5 of the whole bucket of tanking slurry, once mixed with water, covered approximately 2.5 square meters of wall so I’m expecting the whole lot to do 12-12.5m2

Rated 1 out of 5 by from Horrible to apply I followed the instructions but the result was a solution that did not apply evenly.

Rated 5 out of 5 by from Exactly what I need Had some porous mortar that in the back of a garage. I’m not a builder and needed something to help seal it from the inside. Covered the whole wall in it after re-pointing the brickwork. Taken a long time to dry but it has been exceptionally cold! Had some decent rain and it’s as dry as a bone! Great success!

Rated 5 out of 5 by from Easy to mix and work with, so far all good. Seems to be doing what it's meant to do. Good instructions.
