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

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.

If you want to re-caulk your bathtub, Flex Caulk is an excellent product. I’ve never done caulking. So I thought I’d try it myself using this product. I bought a caulk scraper n Amazon for under $10. That is essential to remove the old, ugly, blackened caulk. Yes, that’s some hard work which took about 30 minutes of scraping and washing. But once that was done, the flex caulk worked really well. You set the bottle for the lowest bead size. And you just press and move the bottle along the gap where the caulk should go. No, I didn’t do a super professional job. But overall it looks great and much better than before! The problem I had was not consistently just moving across the gap. I stopped a few times, and the caulk can build up in certain spots. Then you need a paper towel to remove it. And you need to wear gloves as caulk is very messy. But if you just glide the bottle and press you will get a beautiful bead. It dries fast. They say 24 hours for complete hardening. And now 90% of my caulking looks great. But there are a few spots where it got a little messy. Overall, I am very pleased with this flex caulk!

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.

Before purchasing, I read reviews which said this product was difficult to figure out and to use. I had a very different experience. Pull off the red cap with pliers and follow directions on the package or tube. I reinforced some caulking on my camper while standing on a tall ladder. I could not have accomplished this while using a caulking gun, but with this product it was easy, peasy. I will update this post if I experience negative effects, especially if it stays tacky. It v was cold when I applied it (35°) but nothing on the packaging called for certain temps. So far an easy to apply product.

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!

The jury is still out as how effective it as I have only used it once on a shower drain. My only complaint, $19.00 for tube that is no bigger than standard caulking tubes that are half the price. From now on, I will stick to a caulking gun.

This product is fabulous and works as described! I love it and have used it on my window seal, bathroom tub and kitchen sink!!
