Stormdry MAX - Enhanced waterproofing, crack-bridging and anti-graffiti protection barrier for brick, masonry, concrete, stone, metal and painted surfaces

I used this to fill cracks in rendering. It’s got good adhesion, it’s got good flexibility so that with changes in temperature it won’t crack. It’s waterproof and it’s easy to apply as it flows into the cracks and seals with a watertight seal

Went in easily, so far has proved to do the job!

I used this in conjunction with Stormdry masonry cream. The back wall of my house now appears to be cured, rainwater just beads and runs off with no water dripping down through the internal door heads any more. This product is silicon based, so acts as a coating when dry.

Water had been coming into one of my chimneys for years. I'd tried fixing it many times witg different product. The chimney was sound but when the wind blew in a certain direction rain got in. I used this with its partner no more leaks. I write the nunerous storms since.Goes on easily and dries clear. I slapped it on with a large brush accepting that the brush was going in tge bin when finish.Worked great.

Total nightmare.. I bought 3 of these and painted my old stock brick wall last summer to prevent frost getting into the cracks in the wall... the walls were very dry when I painted them as we’d had a brilliant summer.Now in March the storm dry is all peeling off and taking lumps of my wall with it.DO NOT USE!

must use in conjunction with Stormdry water proofer as a primer.Crack bridging needs to be used in conjunction with Storm Dry water proofer as a Primer 24 Hours before cracks are sealed

Following water egress last winter I had the entire western gable end of our house repointed and then applied StormDry Masonary Protection Cream as a base coat before applying this product. Rain now runs off like a ducks back. I started to apply the CB coat with a large masonary paint brush but found it quickly became gunked up and congeals the bristles together. A far better way is to use a good quality 'wool' roller. Coverage is improved and so is application, with the coating penetrating pits in the brickwork.

This is my second review after 3 months. Apart from waterproofing a solid brick wall of my house, 324 years old there are now additional benefits:1. I have gas central heating and the house is noticeably warmer and the heating cost has reduced considerably.2. There are oak wooden windows, the house is grade 2 listed, in the wall with secondary double glazing. In cold weather there was always damp between the panes. This has now disappeared, evidence that the solid wall has dried out and remains dry despite being exposed and 100 yards from the sea.I am evidence that the Stormdry claims are true. I wish I had known about it before. It is marvellous stuff!
