This 10.1-ounce tube provides a reliable solution for filling gaps, cracks, and joints, ensuring a watertight seal that stands up to the elements. In real-world usage, this sealant performs exceptionally well. The consistency is thick and easy to apply with a standard caulk gun, and it adheres securely to concrete surfaces. It cures to a durable, flexible finish that resists cracking and peeling, even with exposure to moisture and fluctuating temperatures. I used this sealant to repair several cracks in my concrete driveway and basement foundation. It filled the gaps effectively and provided a smooth, professional-looking finish. The gray color blends nicely with most concrete surfaces, making the repairs less noticeable and maintaining the overall aesthetic of the area. One of the standout features is its excellent adhesion and watertight properties. After application, it effectively prevented water from seeping through, which is crucial for maintaining the integrity of concrete structures. It also resists mold and mildew, ensuring long-term performance and durability. Overall, the Concrete Watertight Filler and Sealant is a top-quality product that delivers on its promises. It’s easy to apply, highly effective, and provides excellent protection against water infiltration. Highly recommended for any concrete repair or sealing project!

A very good product for sealing around the foundation of our homes. Helps restrict insect and water damage. Dries quickly and very easy to apply.

It's just caulk lol. DAP makes good stuff so I'm sure it's fine. Easy to squeeze, works like any other caulk, smeer it with your finger. Color doesn't match any of the 4 different shades of concrete and mortar at my house. I used it to fill deeper cracks and left room for regular mixed patch repair on top. It'll be useful for this cursed slate walkway.

Finally!!!! After trying 3 different concrete fillers from lowes I ordered this from Amazon. This stuff is amazing. Looks the most like concrete and actually sticks to it. This is the only concrete filler we will ever use! You should too! Thank you DAP!!!

I’m tired of weeds growing up through the cracks in my driveway. This stuff worked perfectly. In fact I even bought more to fill in everything around the house.

Used to fill a crack in a concrete driveway. I needed a larger bead than suggested so the tube only covered about 10 feet. I bought a second tube to finish the job. It applies easily and is best smoothed with a finger in a latex glove. I noticed it appears white when the driveway gets wet so keep in mind. Fortunately the crack was in the concrete seam so it was hidden.

Love this stuff. Easy to apply, seals perfect. Can’t find in stores anymore. Good thing there’s Amazon

good price, fills small cracks in concrete, use foam backer rod if filling bigger crack. matches concrete color.
