Adjustable Trigger-Flow Nozzle.
Lets you control the flow, so you can always “dial up” the perfect bead size. Turn it down for pinpoint precision. Crank it up for maximum coverage.
Won’t shrink, crack, or become brittle.
Unlike other caulks that dry out Flex Caulk’s innovative hybrid polymer formula allows it to expand and contract, and stay completely flexible.
Works indoors and outdoors.
Flex Caulk is 100% waterproof and weatherproof, as well as chemical and UV resistant. Plus, it’s solvent-free and virtually odorless.
Clings to wet and dry surfaces. Even underwater.
There’s no need to wait for surfaces to completely dry before caulking them. It even works underwater!
Apply to almost any surface.
Bathrooms, kitchens, sinks, showers, toilets, backsplashes, counter tops, baseboards, mouldings, pipes, skylights, windows, doors, autos, boats, and more.
Made in the USA

DIRECTIONS:
Adjust the flow setting to the desired amount.
Hold at a 45° angle, push trigger down, while moving the nozzle in an even motion.

After use, secure the “Snap & Save” cap tightly on the nozzle.

This stuff is great. Just read and fillow the directions. My knight in shining armor didn't read the directions (I did) and used WAY too much. This Flex Sealant works great and doesn't need to be overloaded with calk. It's sooo easy to use and apply ( if you read the directions). I bought the white because you got nearly twice as much as the clear for the same price. That's easy math unless it's a visible space you're using it on. It holds super well, it, oddly, comes easily. A lot goes a long way. When this tube's empty I'll be buying another one.

This was very easy to use and so much easier to use than a caulk gun. Plus you can recap it. The color of white was actually white not a cream color. Nice product.

Worked but hard to use because it got all over everything. And I do mean everything even though I tried to be careful. The fact that it is clear was a big bonus.

You could pretty easily buy a caulk gun and a tube of caulk for the same price or less than this one can. I have no complaints about the product itself it’s good caulk but I have trouble imagining who I would actually recommend it to at this price. Just buy a nice caulk gun and then if you ever need a new tube of caulk or you need a different color it won’t be prohibitively expensive. Seriously you can buy a tube of caulk for like $2. But if you don’t care about money at all and don’t plan to caulk much and just need it for one thing this will get the job done.

I recently used Flex Caulk in my bathroom, kitchen, and basement, and it has worked perfectly. The application was smooth, and it adhered well to different surfaces. It provides a strong, waterproof seal, preventing leaks and moisture buildup. I also appreciate that it remains flexible over time, preventing cracks. Overall, a fantastic product that delivers exactly as promised! Highly recommended!

This is a thousand times better than using a caulk gun! I can't speak to how the caulk actually holds up because I only just applied it, but it flowed out so evenly and smoothly! I did still opt to tape off the edges this time to create clean lines, but next time I may not need to because this caulk applied so evenly.

I used it to seal a seam between a tube and the floor. It was very easy to apply, and it was great that you didn't need a caulking gum. The only downside was that it was expensive. Waiting to see how durable and long lasting it is.

Have used this for a small outside job and it's very cold where I am and as of today it's doing its job. Holding in this winter weather and easy to use.
