Histórico brand, works as intended to fill concrete cracks

Dap has a good reputation and you’ll find it in most reputable hardware stores. I’ve used it many times and it’s been consistently good.

Fills cracks easily and looks great. I used a putty knife and dry cloth to polish off while wasting nothing.

The stuff works but you want to be sure you clean the surfaces your sealing to get the most out of it.

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.

I've been using this to fill cracks in our sidewalk and driveway. Since the ground continues to shift a bit I have to re-apply this from time to time to fill the cracks. I guess if the product had more elasticity it would be better than it is, but as it is it's an okay product. When it dries it is a darker color that the regular color of dried concrete, but isn't too far off.
