Filling small cracks in concrete
Frost or changes in the grade around your
home can cause
¼
- to
½
-inch wide cracks in
concrete. Such cracks lessen your home’s curb
appeal but can become much more problematic
if not sealed. To prevent minor annoyances from
becoming large problems, check your concrete
early every spring. Fill in any cracks with a
concrete crack sealer.
Follow these steps to fill small cracks in concrete:
1. If the edges of a crack are smooth, use a wire
brush or chisel to roughen them.
2. Use a brush or vacuum to clean out any
debris from the crack.
3. Measure the crack to determine its depth.
If it is less then
½
-inch deep, move to the
next step. If it is more than
½
-inch deep,
fill it to
¼
-inch from the surface with
backer rod or sand.
