Flex Caulk, Waterproof & Weatherproof Hybrid Polymer Sealant, Strong, Paintable, Indoor, Outdoor, Bath, Shower, Sink, Window, Baseboards, Door, RV, Roof, Wood, Auto & Marine, White, 9 oz, 1-Pack

I got this product to help in my battle against my landlord special of an apartment and it DID NOT disappoint. From cracks around doors and windows that the light shined through to the seam under a sliding door and so much more, this product did the trick to seal up the drafty spots. It’s super easy to use and reuse. Unless you’re really looking for it you won’t even know it’s there and there’s no foul smell to it either. It sticks well to itself and to whatever you put it on. A little went a long way for me! 10/10 would (and probably will) get this product again.

This is hands down the easiest to use. No need to use a caulking gun. The caulk comes out uniform and consistent. I sealed 2 bathrooms first then save it to use later for the last bathroom. The consistency remained the same. Cleanup was super easier and has been the fastest that I've completed sealing all the bathrooms. Would highly recommend.

We purchased this to fill gaps around our home and it worked so well. I was worried about and odor since we needed to use it indoors and after using it in several places, there still was NO smell!! If you’ve ever had to use a silicone caulk then you know that’s huge. We had used the General Electric brand prior and it smelled SO strongly. We purchased the clear silicone and it truly was clear. No grey or cloudy color once dried. The squeeze handle made it much easier to use compared to having to use a caulk gun or your fingers to squeeze the tube. We would definitely purchase this again for other projects around our home!

Is great product easy to use

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

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!

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.

It sealed up the crack in my humidifier ; works like new!!
