There was a issue with the guttering but with that sorted decided to use this on the walls to protect from rain and wind. It has been a great success, walls are lovely and dry. Did put on 2 good coats on in dry conditions, it does have a slight sheen to it but doesn't affect the look of the brick work. I was so impressed that I actually used it on the grouting of my garden paving. I also had issues with it lifting and coming out when I was washing with hose etc. Anyhow I decided to paint the waterproofer on the grouting, again a good couple of coats and I am amazed at the results. Water no long seeps into the grouting, runs off plus it has made it more secure. Amazing stuff. Review: Worked great on a window frame leak! - We had a leaky window where it hadn't been sealed properly. 2 coats of this and the problem was fixed! It's brilliant for leakage prevention around windows or external walls .Its quite a runny liquid so make sure you use masking tape to tape up an̈y areas that aren't to be sealed! It dries fairly quickly (in a few hours) The tub goes a long way, so very cost effective. Recommended. ## Features - DIY Clear Sealant Waterproof Silicone: The transparent waterproof coating kit includes 501 grams of sealant, two small brushes, and a pair of gloves.
