How to Repair a Stamped Concrete Porch

Repairing a concrete porch is no different than repairing any other exterior concrete surface such as a driveway, walkway or patio. Stamped concrete provides an especially durable surface that also requires minimal maintenance, however they can still end up getting damaged. If you have cracks and holes in your concrete porch due to frost or other damage, you can normally repair the localized area without a great deal of trouble. Anyone who feels comfortable with basic DIY skills can save money by carrying out the repairs themselves.

Tools and Materials Needed:

  • Broom
  • Color hardener
  • Concrete fortifier
  • Protective gloves
  • Sponge
  • Paint brush
  • Release agent
  • Exterior concrete sealant
  • Wire mesh

Step 1 – Prepare the Surface

Before you can begin carrying out the repairs, you need to make sure that you have made the right preparations and that the weather is dry and forecast to remain that way for the day. All particles of dirt must be thoroughly swept away from the porch floor and the surface should be properly cleaned. Leave the surface to dry completely before actually carrying out the repairs.

Step 2 – Mix the Concrete Fortifier

The concrete lithochrome color hardener needs to be mixed in with an appropriate acrylic concrete fortifier. Follow the manufacturer’s specific instructions for further advice on how to make the mixture. The color hardener should be filtered through a wire mesh before applying it to the concrete fortifier so that any chunks that make it course are separated. Make sure that the color hardener has no chunks before applying it to the fortifier and mix following the manufacturer’s directions. This concrete fortifier will make the bonding of the repairs much stronger and more durable.

Step 3 – Apply the Mixture to the Damaged Stamped Concrete

Carefully and thoroughly work the mixture into the damaged area of concrete. For smaller areas you can do this with your finger providing you are wearing protective gloves. For larger areas, you can use a paint brush or even a sponge. Work the mix into the surface evenly, making sure that it is flush with the surrounding concrete.

Step 4 – Apply Release Agent

Use a release agent which is specifically designed for stamped concrete, such as Litholex. This will assist the printing of the pattern onto the cement surface. For a large extent of damage, you will need to repair the pattern as well. This pattern needs to be matched and pressed into the repaired area before the cement sets. Before sealing the surface, allow the cement to dry thoroughly.

Step 5 – Seal the Repaired Surface

Use an appropriate exterior concrete sealant. This will help to protect the repaired surface by making it more durable. Sealant should be thoroughly placed over the entire area that you repaired. The sealant can be applied with a paint brush. For further instructions on sealing a stamped concrete surface, refer to the manufacturer’s guild lines. Finally, leave the porch floor to dry before it is used.
