If necessary you will also require mixing supplies as well as a wire brush, a soft bristle brush, a trowel, a straightedge for smoothing the finished area, a shop vacuum, and epoxy sealant.
#Porch slab crack repair Patch#
To patch a hole or a recessed area on a concrete porch you will need a container of ready-mixed concrete patching material, or you can save money by using a dry mix. Holes on the surface of a concrete porch are relatively easy to patch, but it generally takes more than a single tube of patching material to complete this type of repair. Holes sometimes develop in a concrete porch because of a crack that widened or because the material was improperly mixed or cured. Wipe the top smooth with a wet rag, and allow it to dry completely before allowing access to the porch. Apply the concrete patching material according to product label instructions, and allow the layers adequate time to dry in between applications. If the crack is deeper than the width it will have to be filled in using layers of vinyl patching.

Once the crack has been cleaned and is dry, brush away any loose pieces with a wire brush, and use a softer brush or a vacuum to clean away smaller particles of concrete, dirt, and debris.

In addition, the concrete must be completely dry before repairing, and a leaf blower can be a helpful drying tool if the porch is slightly damp. A shop vacuum is also helpful for completely removing dirt, dust, and loose debris. You will need a tube of vinyl concrete patching material, a wet rag, a soft bristle brush, and a wire brush. Cracks in a concrete porch less than three-eights of an inch wide can be easily repaired.
