I have tried three other products over the years in an effort to stop leakage in my waterfall and none could do the job. Finally I found this product and based on reviews gave it a try. Used two coats and after a full month can report "no leaks, no drips and no errors". Fantastic product.

Bought this to coat cement boards for new shower. It goes on easily, and has a consistency of pudding. It seems to provide a solid barrier. The biggest issue I've encountered are the terrible, seemingly never-ending fumes it gives off. It has been 5 days since I used this product, and the bathroom fan has been running continuously (the fumes are still noticeable!).

    This product works well. It goes on smoothly and once dry, it still has some adhesive so things stick to the membrane. We are applying tile to it in the bathroom. The only issue is that it will tear if anything sharp touches it. Overall great product.

    I had water coming in from an addition that was put on wrong before I bought my house. After applying this we had a heavy rainfall and not one drop came in. Easy to apply and works great.
