Of the numerous concrete crack repair products available, this one really works.This driveway caulk is like a permanent

rubber gasket. It is an easy to apply, two component caulking called 'Polyurea' available at Sherwin Williams. It is self-leveling which means it flows to fill the crack and levels at the top. This means it smooths itself out. It is a commercial grade product but all you will need to use it is a heavy-duty caulk gun. It is best to have a recently washed driveway and you need to remove any old failed crack fillers. It is important to caulk driveway cracks. If you don't, the edges will break off the cracks, forming little pot holes of ever increasing size.

The last driveway caulk you will ever need.

    It will work as good as any crack filler can; just scratch out the old caulk first with a 5-in-1 tool from The Depot or SW, and it work for years to come. It's worth the effort to save the driveway. Also, as A.I. mentioned , it's good to clean off the concrete dust from inside the cracks before applying the new caulk, so it can properly adhere. The simplest you can do this would be with the hose and a brush inside the cracks. Just let it completely dry before the new application, which will probably be the next day. One more thing, this product, like most others, will not work well in the direct sun, so apply it early or late in the day. Best, Charles
