Rated 4.8 out of 5 by 14 reviewers.
Rated 5 out of 5 by Worth Doing This really is an excellent product goes on easily by brush (or spray) with a single coat. An hour of work one summer afternoon, will puts a smile on your face on a wet night in the middle of winter, as the beads of rain sit on the surface of the brick work unable to penetrate the masonry. 19 September 2011
Rated 5 out of 5 by excellent quality used this product a couple of weeks ago,it does exactly what it says, only one coat required, brilliant !!!! tried to put second coat on and wouldn't have it . 12 April 2013
Rated 5 out of 5 by One Coat Water Seal Ultra is great Applies really easily with a thick brush. Rain water now bubbles on coping stones rather than soaking in, just like the picture shows on the tin. 02 August 2012
Rated 5 out of 5 by Good job I have a lot of small ornamental walls in my garden and round my property I didnot want the bricks to go white as they look awful. This one coat water seal (clear) was ideal for the job, only one coat perfect. Very easy to apply and a great finish acheived. Very impressive. 17 November 2011
Rated 5 out of 5 by superb cover We applied the water seal to the external granite wall we had exposed fully expecting to put on a second one just in case. When we tried the second one would not soak in as the first one had already made a barrier as described - great product 17 November 2011
Rated 4 out of 5 by Trusted manufacturer This is a relatively new product and it's the first time I have used it. A little bit more expensive than the basic water seal which pays you back as only one coat is required. I am coating my whole house, recently had cavity insulation installed and I am concerned about my porous brickwork which could affect the performance of the insulation.........used 40 litres to date.......another 20 to go. Very pleased with the beading effect as the rain just trickles off. 11 November 2011

Rated 4 out of 5 by good product The product brushed on easily and covered well, no discoloration of stone. We are waiting for a prolonged period of wet weather to judge its effectiveness. 13 July 2011
