GH5932, Reviewed October 1993
If you have small cracks in sidewalks that seem to be growing and make your sidewalk dangerous, they can be fixed.
Work fast. Most epoxies will harden in an hour. If the patch should harden before the operation is completed, apply a second coat and smooth the surface again.
For big cracks, spread the mixture over the full width of the crack until the level of mortar is slightly above the concrete surface. If repairing a full break in the concrete, use the trowel to force the mortar mixture to the bottom of the break.
