How to Layer a Cement Sidewalk
Cement sidewalks can last many years, but the cracks, pits and other signs of wear and tear that form over time can be an eyesore. Removing a damaged sidewalk is laborious and unnecessary if the damage is minor. Layering a new layer of cement over the sidewalk repairs existing damage and makes the whole slab look new. Does this Spark an idea?

1
Clean the old cement using a power washer and scrubbing brush. Pour stain remover over oil stains and scrub it with a stiff brush. Hose off any cleaning solution and remaining debris and wait a few hours for the surface to dry.
-
2
Fill in cracks, pits and any chips in the surface with reinforced vinyl patch compound. Use a putty knife to tamp the compound into the holes and fan the material over surrounding cement with a flat trowel.

3
Cover any expansion joints with strips of duct tape long enough to extend across the width of the sidewalk. Expansion joints are semi-flexible material installed between sections of a slab to allow the cement to shift and expand without forming jagged cracks.
-
4
Empty a bag of concrete mix in a large wheelbarrow, adding small amounts of water at a time. Stir it with an electric paddle mixer until it has a spreadable consistency.
-
5
Scoop small piles of concrete over the sidewalk, using a shovel. Have a helper spread a 1/4-to-1/2-inch layer of concrete over the sidewalk with a trowel. Push a squeegee across the width of the sidewalk to remove any impressions left by the trowel.
-
6
Move a medium-bristled push broom gently over the wet concrete to add subtle texture so the surface will be slip-resistant.
-
7
Remove the duct tape covering the expansion joints and wait about two days for the surface to cure before allowing foot traffic.
