DAP Concrete and Mortar Filler and Sealant, Gray, 10.1 Oz (7079818096)

Very pleased with this concrete and mortar filler sealer. It arrived on time and in perfect condition, no damage to the packaging. Works exactly as described and did a great job sealing up cracks in my concrete. Easy to apply and dries to a durable finish. Would definitely recommend and will buy again for future repairs.

The DAP Concrete Mortar Filler worked well. It was easy to apply and filled the concrete cracks quickly.

Much lighter grey than mortar, much lighter than picture of tip. Great sealant, but may need to paint to match.

The filler applied easily and smoothly to seal concrete cracks around a fireplace and bricks. It began to harden within a few hours but will take a more time to be completely dry and solid. Everything met my expectations and lined up with the advertisement.

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!

Great concrete sealant. Works great to waterproof our driveway.

I’ve used this many times and it’s very good for the price, doesn’t last as long as Vulkum, but doesn’t cost 4 times as much either. Do not ever buy any of the overseas knockoffs they have on here, believe me when I tell you they are absolutely worthless! This will last many years!

Color is way too light to match brick mortar. I tried putting dark grey magic marker on this caulk but it didn’t work well.
