How to Patch a Hole in a Cement Wall

By Kimbry Parker ; Updated September 21, 2017

Cement is a durable material, but it's not uncommon for it to crack or chip. Cracks in cement walls can lead to holes if they're not fixed in a timely matter. Holes in cement walls are not only unattractive, they can lead to larger structural problems if not fixed properly and quickly. Fortunately, you can patch a hole in a cement wall yourself without professional help.

Step 1

Chip away any cracked edges of the hole before patching it. Use a small sledgehammer and cold chisel to break away the cement along the cracked edges.

Step 2

Clean out the hole using a wire brush. It is important to remove any loose cement or other debris from the hole so that the patch will adhere properly.

Step 3

Prepare a batch of cement-patching compound in a small bucket. Follow the manufacturer's instructions.

Step 4

Use a putty knife to scoop out a generous amount of the patching compound onto a small board or straight-edge taping knife. Hold the taping knife or board with the patching compound at the base of the hole.

Step 5

Force the patching compound into the hole using a putty knife. Fill the hole completely with the patching compound until the compound is overflowing from the hole a bit.

Step 6

Smooth out the patch using a pointing trowel. Use the edge of the trowel to go back and forth over the hole to smooth out the patching compound. If the hole is really large, use a large trowel to smooth out the patch.

Step 7

Allow the patching compound to dry and cure according to the manufacturer’s instructions.
