Different Ways to Repair Concrete for Your Home

Concrete is one of the most durable, economical and versatile building materials, used on everything from driveways to lighthouses. Concrete in its simplest form is a mixture of paste and aggregates or rocks. The paste, composed of Portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called – Hydration, the paste hardens and gains strength to form the rock like mass known as “Concrete”. Within the process lies the key to a remarkable trait of concrete. It’s plastic and malleable when newly mixed, strong and durable when hardened. These qualities explain why one material, concrete, can build skyscrapers, bridges, sidewalks, and superhighways, houses and dams.

5 Steps To Repair Concrete Cracks:

Clean the Floor

Before using any concrete filler, make sure there’s no oil or dirt still on the floor. If there is, use a cleaner that cuts grease. This will help the filler bond to the cement.

Step 1

Chisel the Crack Clean

Use a cold chisel and a hammer to get rid of any large pieces in the crack. Hold the chisel at an angle and pound with the hammer to chisel out the crack. This is called “keying” the hole to make the base or inside of the crack bigger than it is at the surface. Keying helps the new patching material bond with the old crack.

Step 2

Brush and Vacuum

Once you’ve keyed the crack, it’s important to clean up and get rid of dust and debris. Use a whisk broom, then vacuum the crack thoroughly.

Step 3

Spread Concrete Patch

To use the concrete filler, cut the nozzle off the bottle and slowly fill the cracks. If you’re using the mixed concrete patch, mix according to the manufacturer’s direction and then trowel the patch into the crack. Check the cracks in a few minutes to see whether the filler has settled. You may have to add some more if it doesn’t look right. Use a trowel to smooth out the cracks.

Step 4

Allow it to Cure

Allow the filler to cure overnight. Then check it again to see if any additional patch is needed.

Step 5

Seal the Patch and Concrete

After patching the concrete, it’s a good idea to seal it. Concrete easily absorbs stains, and sealing will prevent that. There are more than a few products available for concrete sealing, but a heavy-duty water-based polyurethane is a good choice. If the floor has a rough finish, apply the polyurethane with a broom or brush using the bristles to work the sealer into the rough surface. For a smooth surface use a roller.
The beauty of water-based polyurethane is that it dries quickly, so you can put on a second coat just a few hours after the first. Also, water-based polyurethanes don’t smell as bad as other types of sealer.
