How to Repair Stamped Concrete

Stamped concrete is used for patios, driveways, porches and, sometimes, walkways inside the home. Many small cities use stamped concrete to create a look of elegance and style. Its name comes from the way the design is stamped into the concrete. It can get rather expensive, depending on the size of the area it is used. After installing, you'll want to make sure it remains in good condition. You can repair a crack or other damage to a portion of the concrete without having to replace everything.

Sweep and wash the slab of concrete that needs repair. Ensure that no particles or dirt get mixed in.

Mix Lithochrome color hardener with Quikrete acrylic concrete fortifier. Check the color hardener for coarseness by sifting it through a mesh screen. For best results, the color hardener should not have chunks in it. The fortifier will enhance the bonding.

Work a slurry of the mixture into the damaged part of the stamped concrete. Choosing the right tool depends on how large the damage is. If it is a small crack, you could probably use your finger, as long as you are wearing gloves. If the damage is larger, then use a sponge or paint brush.

Put a release agent on the repaired area. A specific release agent used for stamped concrete is Lithotex, a clear liquid that helps with imprinting a pattern into the cement. If the damage to the concrete is large enough to have to repair the pattern, then you will need to match the pattern used and place it onto the repaired area. Press down on it and carefully remove it.

Finish cleaning and sealing once the repaired area is dry. Sealant should be placed over the area.


Cleaning and sealing should be done regularly (every two to three years) to keep the stamped concrete in good condition.


Repair the smallest cracks to prevent it from getting bigger.
