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.

Would RecommendI had never used Flex Paste before and had need for something like its application instructions called for: waterproof, fast drying and strong. I had a cedar covered steel gazebo that had rotted under the cedar facia; big fist size spaces. Flex Paste filled in those spaces easily and quickly then dried into a strong mass and provided a solid, waterproof base now covered with new aromatic cedar facia. Perfect repair, stronger than when new!
