Flex Caulk Hybrid Polymer Waterproof Sealant, Clear, 6.6 oz, 1-Pack

This works so well. I’ve had a problem with water leakage in one spot between steps and sidewalk. I used many different products and nothing worked. The Flex Caulk got deep into the crack and the leak has stopped. It was the clear caulk!

I've always wanted to try flex products. Their advertisements are the best. One day while it was raining, I found out that water was leaking into my car around the antenna. So I ordered this and then later that day I was able to seal up my car while it was raining with no issues! I highly recommend! Thank you, Phil!

I didn't realize this existed. No caulk gun needed. I don't recall an odor when. using it. It can be closed and used another time! It has a twist nozzle that allows you to adjust the bead size. Perfect for smaller jobs. It provides a strong waterproof seal. Heavy storms have always forced water into a corner of my kitchen but not since using this. I've painted over it and you wouldn't know its there. Very durable and sets quickly.

Works as expected. easy to clean up. decent value for money

I figured this would work once and then get all hardened and not work again later. Turns out, I was part right. First the silicone is great for resealing a bathtub and the first use was super clean. Just a firm, constant squeeze after setting the thickness you desire gives a consistent and air-bubble-free caulk line. Two months later, I had to rub some dried material from the tip and press pretty hard to get the material to flow, albeit much slower. Thankfully, I didn’t need the precise flow control, so I pulled the cap off, was able to get ample material that was ready to use just like new, and then clip the flow control cap back on. So, not perfect, but very much as advertised and I would buy this again when needed.

Nice tutorial and easy to use. Really worked quickly and just as directions stated. No odor. Sealed up quickly.

I bought this specifically to seal a few small leaks in my gutters, but unfortunately it did not work for me at all. I followed the application as carefully as I could and expected a waterproof seal, especially since the leaks were very small, but water was still coming through afterward. I even tried using it on tiny problem areas where I thought it should have been an easy fix, and it still didn’t solve the issue. For a product advertised as waterproof and weatherproof, I expected much better performance. It may work for other applications, but based on my experience with gutter repairs, it was not effective. I ended up having to look for another solution, so this was disappointing and a waste of time for the job I needed it for.

Just what I was looking for
