I've tried two different products?on my concrete driveway in cracks that ranged from?about 1/16" to 1/2" in width?and up to 3" in depth and?8-10 feet in length.??At the recommendation of a friend who is home improvement contractor,?I?put DAP Concrete "Concrete and Mortar?Filler and?Sealant" in the?narrower and shallower cracks and Quikrete Sakrete filler in the?wider and deeper cracks.? The DAP product came in?a caulk gun tube and the Quikrete came in a?larger?"squeeze" bottle.? I did this only in July though, so I don't know how they will hold up over the winter.
