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

Caulking isn't new to anyone, but for the homeowner or renter who occasionally needs a bit of caulk and wants it ready to use at a moment’s notice, this is the product to reach for. Unlike traditional tubes that require squeezing and can be messy or inconsistent, this applicator features a push-button mechanism with adjustable flow control—making precise application effortless and clean. The design is intuitive and ideal for small touch-ups or quick fixes around the house. While it may come at a slightly higher price point, the convenience, reliability, and ease of use make it a worthwhile investment for anyone who values having the right tool on hand when needed.

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.

Very easy to use. Much more so than using a larger caulk tube with caulk gun. I was able to maneuver between wall and faucets easily with a steady bead. The flow control and tip was perfect to to fill a large gap as well as smaller ones. Only issue inhad with the order, I recieved clear instead of white. I double che ked the order info and it clearly show white. Since I had large gaps to fill I used it anyway. I ordered again to put white on top of clear to finish the job. Will send back this time if white isn't recieved.

Edited Review: Changed rating from 1 star to 5 stars I originally gave this product 1 star because I received a can labeled white, but caulk was CLEAR. After complaining to Amazon and requesting a refund, the seller after reading my original review promptly contacted me and sent me a replacement can which contained the correct WHITE caulk. There was genuine concern on the part of the seller to correct the error and find out which lot number was mislabeled. I have changed my rating to 5 stars. The concept works perfectly since it is easy to use. Since no caulk gun needed. There is adjustable trigger nozzle that works perfectly. Now that I got the correct product, I was able to quickly and easily caulk my bathtub with a minimum of effort. Great product!

I’d been trying to fix a leak in my birdbath and was fed up with the mess that the regular waterproof silicone made. It’s so hard to push the middle of the tube up to dispense unless you have a caulking gun dispenser. This Flex Caulk is so easy to dispense and worked perfectly
