How to Repair Cracks in Concrete
More in Outdoors
Step 1: Chisel and Grind the Crack
Chisel and grind the crack to make a wider area for patching. (You'll need a wider area so the patch material will adhere better.)
Step 2: Vacuum the Crack
Clean surface of all dust, dirt and loose material -- and vacuum the crack.
Step 3: Mix the Patching Material
Mix the patching material to a plastic-like consistency.
Step 4: Dampen the Surface
Before applying the patch material, dampen the surface with a water spray.
Step 5: Apply the Material
Apply the material with a margin trowel or pointing trowel and smooth it out. After it's semi-dry, clean the edges of the crack with a wrung-out sponge.
Step 6: Apply the Sealer
Don't walk on the surface for at least 24 hours. Roll on a water-based sealer after the concrete has cured.
