How to Fix Small Concrete Cracks: a DIY Guide
Here in Indianapolis, winters can be rough on concrete, so cracking is a common occurrence. Not only can cracking be dangerous if tripped on, it can also be a liability if you’re wanting to sell your home. Not surprisingly, we hear the following a lot: “My concrete is cracked. Help!”
If your concrete is cracked, repairs are possible. In fact, small cracks can often be taken care of yourself if you’re a DIY-er. If your crevices are more substantial, we recommend calling a professional (like us).
Here are 9 quick and easy instructions to help you fix small concrete cracks:
Here’s what you need: hammer, chisel, margin trowel, wire brush, jointer tool, brush or leaf blower, hydraulic cement, small container (like an old butter container), plastic bucket, sand, water.
- Use a hammer and chisel to enlarge the crack. (It seems counterintuitive, we know.)
- Ensure that fresh cement will adhere by undercutting the crack or creating a u-shape.
- Use a brush or leaf blower to clean out the crack.
- Take a small container (such as an old butter container) to measure your hydraulic cement (and later your water).
- Put the hydraulic cement in a plastic bucket, where you will mix in the water with a margin trowel.
- Place the hydraulic cement into the crack ½ inch at a time. It will dry quickly, so work fast!
- If you have a deep horizontal crack, add sand within ½ inch of the top of the crack.
- Use a jointer tool to shape the hydraulic cement.
- Take a wire brush or margin trowel and clean off excess cement.
…and there you have it!
