*by X***U on 17 December 2025*

Excellent Waterproof Sealant – Highly Recommend! I’m extremely impressed with Flex Caulk. This stuff really delivers on its promise of being waterproof and weatherproof. I used it to seal around windows and outdoor trim, and it went on smoothly with no mess. The adhesion is strong, and once it cured, it formed a durable, flexible seal that holds up perfectly against rain and temperature changes. What I like most is that it doesn’t crack or shrink like other caulks I’ve tried. It also looks clean and professional after drying. Whether you’re working indoors or outdoors, this product gets the job done right the first time. If you need a reliable caulk that truly lasts and protects against the elements, Flex Caulk is absolutely worth it. I will definitely be buying it again!
