    Easy to use
  

*by P***N on Reviewed in the United Kingdom on 25 November 2023*

Purchased this product to fix a wooden widow frame that leaked when we had heavy rain. Product was easy to apply and easy to clean off any overspray. Doesn't take long to dry so I was able to apply two coats within 30 minutes. No more leaks despite frequent heavy rain in last few weeks.Excellent product and good value for money.

    Crusade to cure leak stemming back decades
  

*by D***3 on Reviewed in the United Kingdom on 20 August 2023*

We have a problem chimney, or a problem wall, or both. It’s the bane of my existence. Some people talk about ghosts haunting them. We don’t have ghosts but our damp wall haunts me.I’m sure there’s multiple issues,  but one thing is for certain is that a drip comes down from the top of the chimney stack. I had new pots fitted and new flaunching. And still the bar steward leaked. Cue more scaffolding and I got up and had a look myself. The new flaunching had cracked, I can’t blame the workmen, I guess it’s the nature of the beast.So I bought this stuff. Facebook is full of periodic building buffs who claim I’ll be going to hell for using this product on a historic property, but you know what? It seems to have stopped our chimney leak from the top.I applied it with a brush. It’s quite thick but also runs if you’re not careful. So apply thinly and add additional coats of needed. It dries relatively quickly and gives a silicon seal looking film over the material applied to. Placing a hose on it generated no leaks, have I succeeded in solving one of my issues with my nemesis wall? Will it last? I don’t know. I hope so, as scaffolding is £500 a pop is too expensive to keep messing around with. But initial results are encouraging.
