Your home's concrete patio can be a focal point for family activities or entertaining friends and neighbors. This is why you wanted to be as attractive and well-maintained as possible. However, ensuring that your patio always looks good sometimes means having to make repairs to occasional small cracks. While this might seem challenging at first, it's actually quite easy to do if you have the right tools and know how to go about it. The following will show you how.

What You Will Need

  • Tubes of Epoxy
  • Garden Hose
  • Caulking Gun
  • Muriatic Acid
  • Neutralizing Solution
  • Concrete Mix
  • Protective Gloves
  • Protective Eyewear
  • Trowel

Step 1. You want to choose a calm day with moderate temperatures when you are repairing a crack in your concrete patio. A slightly overcast day (but not raining) would be a good choice, since this will help to prevent the patch you will be applying from drying out too soon. You don't want the weather to be too cold, since this can also adversely affect the patch.

Step 2. Make an inspection of your patio to determine the extent of the damage. It may be that you have damage in more places than you had initially noticed. It's important to know this, since you will be determining how much injectable epoxy you will need based on this assessment.

Step 3. Purchase the necessary materials from a home improvement store or a concrete distributor, making sure you buy enough to fill the cracks you found in step 2. The manufacturer's instructions will help you determine just how many tubes of epoxy you need.

Step 4. Use a garden hose to wash down your patio so it is perfectly clean. Allow the patio to dry.

Step 5. Put on protective gloves and eyewear, since you're going to be dealing with acid. The reason you're using the acid is to completely clean the old concrete so the new concrete will better adhere.

Step 6. Mix one part muriatic acid with three parts water and drizzle the solution evenly onto the concrete. Use a scrub brush to brush the acid into the concrete.

Step 7. Spray a neutralizing solution on to the concrete. Then rinse it with a garden hose. Allow it to completely dry again.

Step 8. Insert a tube of the epoxy into a caulking gun. Position the end of the caulking gun along one of the cracks and slowly inject a bead of the epoxy into the crack. Try to do this in one smooth stroke. Let the epoxy dry according to the manufacturer's instructions.

Step 9. Mix a small quantity of concrete together and use a trowel to apply a thin layer over your repairs so that the surface is perfectly smooth and even. Let your repairs dry completely before using your patio again.

Note: Keep in mind that large cracks and other serious damage will probably require the services of a concrete repair professional.
