Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers praise the product for reliably stopping water leaks and sealing cracks in roofs, bathtubs, windows, and basements, with many reporting successful repairs and planning repeat purchases. However, a substantial group encountered hardened, dried, or unusable paste upon opening, with some finding half the container unusable. Others describe application challenges, noting it spreads thickly, adheres poorly to surfaces, or dries too quickly. Despite these consistency and usability concerns, most customers who received functional product consider it effective for home repairs.

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!
