Rated 4.3 out of 5 by 8 reviewers.
Rated 4 out of 5 by does what it says on the tin Used this product to seal the brick work on the front of my house as water was seeping through. The affected wall has now began to visably dry out as water beads on outside of wall instead of seeping inside. 14 April 2013
Rated 4 out of 5 by One coat water seal To quote the competition, "it does what it says on the tin." Good reliable product, if you can find it. Why? Because unlike all the other water seals, Ronseal included, this one is parked somewhere among the boards and timber. At least Customer Service knew where it was. 09 January 2013

Rated 1 out of 5 by Useless Applied to the outside wall as directed and waited and watched. The inside wall still became wet when it rained. What a waste of money and effort. 01 February 2012

Rated 5 out of 5 by Excellent product This product is easy to apply on brick surfaces and appears to do the job of sealing the wall very well. 27 September 2011
Rated 5 out of 5 by Good stuff Having previously used a Thompson's waterseal and needing one now I was keen about only applying it once. I first thought it might be a bit messy 'splashing it all over' but the brickwork soaked it up nicely and although 2.5l may seem a lot, realistically it will only cover about a 10' x 8' wall but it was great knowing I didn't have to do it again, which was just as well as it's not cheap. Oddly, there appeared to be no difference the first few times it rained but one day I noticed that the water was beading on the wall so perhaps it needs to be wetted a few times before it activates. Overall a great product and one I would thoroughly recommend. 13 July 2011
