DAP AMP Concrete Sealant, Gray, 9 Oz (7079800764)

Used on driveway cracks. Matches decently on concrete. Fills holes best on hot day.

I love this stuff! I have used it where a concrete wall butts against my cottage exterior wall and the seal is amazing. Very easy to use. It levels out and sets up within a matter of hours. It was dry but flexible the day after using it.

Great stuff. Good price. Self leveling is a must! Plus, it doesn't shrink.

My driveway is relatively new. The builder left driveway maintenance to me. I tried using foam backing rods and caulk, but the wide seams cracked within two years. This time, I used this DAP product with Great Stuff foam. I filled in the cracks with the foam, let it cure, cut the foam back to make a trough, and then covered the foam with DAP. So far, it has worked well. I'm eager to see how many years it lasts this way.One thing to note, my caulk gun has a small pin to break the seal in the tube. Once the seal has a hole in it, I expect it to open up and left the product flow. The DAP seal doesn't do that. I had to stab a screwdriver into the seal to get a big enough hole to push the product out. If you find it difficult to get the product flowing or if it squeezes out the back of the tube, put more holes in the seal.

Good product. Dries fast, easy to apply.

This caulk was applied at 50 deg in damp weather and took several days to cure. The color is a very light grey andn too leight to match normal grey concrete.

This stuff was magic for sealing my driveway. We had some wide cracks in the seams and they needed to be filled. I like how it self-leveled. I wish I had sprinkled a little sand over them to make them blend in a little better, but I didn’t learn that trick until it was too late

I used sealant for cracks on my driveway, works great and drys fast
