Cracked concrete driveway
Part of my driveway has shrink cracks that run irregularly. A total of five. The concrete is not displaced vertically and the cracks are very narrow. The surface is smooth for the smallest of wheels we run over it. Some minor chipping along the edges of the cracks is occurring. I want to seal the cracks with something that is similar in color to the concrete. Asphalt is out. The silicone I have seen used is not good. Urethane sealants such as NP-1 are too stiff and viscous to penetrate these cracks. Considering liquid epoxy. I realize that no sealer is likely to be perfect. Suggestions?
