Rated 4 out of 5 by Very Good Product was good, color just what I wanted, price was very good. Material was possibly a little flimsy, only time will tell if that's right? 07 February 2012
Rated 5 out of 5 by very good did the job thompsons water seal did the job, no odour which was good, dry'd quickly. 01 February 2012
Rated 4 out of 5 by Good job Applied Water Seal to an outside wall to help resist frost damage. While can't comment on frost aspect, the wall does now repel more water and has gained an even colouration. In application it was not always easy to get the brick and mortar surface wetted by the Water Seal, however using a large stiff brush with more of a stippling motion rather than simple brushstrokes got the job done. 04 May 2011
Rated 4 out of 5 by Counter Damp Brickwork This product was used to stop rain penetrating through the brick pillars of a conservatory. It was very easy to apply with a brush and dried within a few hours. The drawbacks were that it needed to be applied in dry conditions and needed several dry hours at a reasonable temperature. Avoid trying to use this product in late Autumn and through to May! 02 December 2010
Rated 5 out of 5 by Works really well I bought this to waterproof some concrete blocks that I was using to hold my new shed off the concrete plinth. I gave the blocks 2 coats on both sides & they certainly work well - there is no sign of any water seeping up the blocks from the plinth. Before waterproofing the water would soak at least halfway up the blocks when they were placed in a 1/4 inch of water. Hopefully this will stop any water reaching the floor timbers of the shed, and stop any spalling of the blocks due to freezing in the cold weather. 05 November 2010
Rated 5 out of 5 by Very good I used Thompson's water seal on some very large garden concrete planters and urns. Having brushed off a build up of moss and algae applied the water seal and it certainly works well, the rain runs off the surfaces very quickly and has had no effect on the plants planted within. Would recommend. 09 October 2010
Rated 4 out of 5 by OK Water Seal Used two generous coats on a new wooden bench. Rain beaded for a while but is now clearly soaking in so will have to wait till dried out and reapply. Thought that two coats would have lasted at least a season but apparently not. 04 August 2010
