What Customers Are Saying
Customers praise the product for reliably sealing leaks in gutters, bathtubs, drain pipes, and basement walls, with strong adhesion to wood, concrete, and metal surfaces. Many highlight its versatility for diverse repairs and quick drying within 24 hours. However, a substantial number report the paste hardens prematurely in the container, arriving unusable or drying out despite sealed packaging. Some find the thick consistency difficult to spread, though those who persevere note it fills cracks well and leaves a professional finish. Despite hardening concerns, most customers report durable results and plan to repurchase.

Top of Tube Already Gelled
Would Not RecommendWhen I opened this and went to use it, I couldn't even get a flow started, even though I used both hands on the caulking gun handle. I pulled the tip and probed with a screwdriver. It appears that the top of the tube was already mostly set.

Rubbish
Would Not RecommendI had purchased 3 lb plastic tub from Lowes. It had been sitting in a heated room for the last several months. I finally opened it up today and found that the paste was not longer a paste, but a large mass of a black rubbery material. Do not purchase if in the plastic container.
