I have a driveway that goes down from the garage to the street, about 25-30 feet. At the very bottom of the drive, just as it touches the curb/gutter, I have patches of concrete that have chipped and cracked away after 28 years of snow, ice, and salt. Is there a way to patch the spots (8 inches by 15 inches or so)? How deep do I chip out the old concrete and what products are best for filling the holes?
First thing to do is use a shop vac to remove all of the loose concrete. Apply a concrete bonding agent according to manufacturers directions to the entire area and allow to dry.
Right before you fill the hole with cement, dampen the area with water using a paint brush.
Trowel in your cement mixture and trowel smooth. After the cement sets up a little, use your brush to blend into existing concrete. You can leave the surface smooth or do a brush affect.
The best product to use for this is a hydraulic cement which bonds better and dries harder than regular cement.
Thanks for stopping by
