Flex Caulk, Waterproof & Weatherproof Hybrid Polymer Sealant, Strong, Paintable, Indoor, Outdoor, Bath, Shower, Sink, Window, Baseboards, Door, RV, Roof, Wood, Auto & Marine, Clear, 6.6 oz, 1-Pack

Worked well to seal air leaks in my 4 seasons room. Super easy to use and not very messy. I already bought another tube. The cap comes on and off easily. Way better then traditional caulk

I am no handyman and definitely not good at DIY stuff around the House, but this practical and excellent product gave me the confidence to seal up my Window in my Basement and it worked flawlessly! I can’t say enough good things about this product! It’s easy to use and does exactly as the product claims and there was virtually no mess!

If you follow the instructions it should work easy peasy. I bought an actual caulk gun with caulk and I hate it. This flex seal product works great It's super easy.

Very good product. I love using it without the caulking gun. Very well made. Don’t use it with your bear hand. Use gloves. I used my finger to spread the caulking evenly. Big mistake. This product is extremely sticky. I had to use white vinegar to get it off my hands. It hardens in minutes, smells ok and it’s clear.

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!

Bought this product to seal a tub and tub walls. This was one of the easier applications I had to do, loved the built-in caulk gun with thickness selector. Made the job very simple, and the product dried relatively quickly. I would definitely buy this product again for other home projects.

Used this to patch some cracks in my swimming pool pebble sheen. Probably not the best product for that but wanted to try something I could use underwater without fooling with a caulking gun. Two problems, the flex caulk tube is pressurized, hence no gun required, however even on the highest flow setting the sealant came out way too slow and did not want to adhere to the pebble sheen surface. In fact, it wanted to float up requiring me to use a putty knife to spread it over the cracks. I may have gotten a tube with a low-pressure charge or this product is not made to apply under more than a few inches of water. Probably my fault for not using a caulk made for pools and sticking with a caulking gun.

I really liked this. I used it to re-caulk the top of an exterior leaking window. The application of the product was super simple and went on clean. It sealed the area and still holding. I would recommend doing Any and All caulking be done same day as opening as it doesn’t store well (hardened at the top of the applicator and in trying to remove, the top thing snapped). But I definitely will be buying again!
