Concrete is an extremely durable material that is used to make everything from paths to walls to furniture. However, while concrete can last for a very long time, it is not impervious to damage. Sometimes, your concrete wall or slab can get holes in it that need to be repaired. Repairing minor concrete holes is easy: All you need is the right materials and a few spare hours of time.
Things You'll Need
- Garden hose
- Wire brush
- Cement mix
- Trowel or putty knife
- Plastic tarp
- Duct tape
Widen the hole using a chisel to a size that you can easily get the concrete patch into. Make sure the the bottom of the hole is wider than the top of the hole.
Soak the area around the hole and the hole itself with a garden hose for at least an hour. Saturating the concrete will keep it from drawing moisture out of your patch before it is set.
Clear away any excess water from the area. Clean out the hole using a wire brush to make sure it is clear of any dust or debris.
Mix the concrete mix and water until it achieves the consistency of thick paste.
Use the trowel or putty knife to force as much of the concrete mix into the hole as possible. Make the mix even with the existing concrete surface.
Allow the patch to dry for two hours. Cover the hole with a plastic tarp (attach it with duct tape if it is on a wall). Keep the hole covered for five days and thoroughly water the area under the tarp once per day.
Tips & Warnings
- When you clear the water away, make sure the concrete is still moist. The moisture in the concrete will help the patch dry properly.
- Force more concrete mix than you think is possible into the hole. You can fit more than you think and if you don't fill the hole completely, the patch may not take and you will have to re-patch.
