How To Repair a Concrete Pool Deck

Pool Deck Crack Repair

Repairing a Cracked Pool Deck

If you have a concrete pool deck or suround you may need to do some concrete repair work at some time or another. In the past, this was a chore but today you can repair most small pool deck problems fairly easily.

An important thing to remember is that when cracks show up in concrete is that they will often only get bigger if you do not repair them. Water can seep into the cracks and then in the winter, the concrete can freeze, and those small cracks can become bigger ones. You can bet on it. If they get too big larger than 14inch your only real option is to have the concrete removed and new concrete poured. This can be very expensive as well as intrusive. Here are some simple steps that you can take to get control of those small cracks today.


  • Angle Grinder
  • Concrete sealer and cleaner
  • Epoxy repair in a caulking tube
  • Steel scrub brush
  • Concrete patch
  • Pointed trowel

   1. To prepare a smaller crack, rinse it out with water ideally a high pressure washer and allow it to dry completely. As you do this, use a steel scrub brush to knock any loose particles away from the crack. It is important that the crack be as clean as possible if a piece of concrete comes loose dispose of it and try to get down to solid concrete.

   2. When the crack is clean, dry, and solid use an epoxy repair in a caulking tube to fill in the crack. Make sure you force it all the way into the crack to seal it. This will prevent water from leaking into the concrete. You can use the tip of the caulking tube to smooth the mortar and then use a pointed trowel or popsicle stick to do the final smooth work.

   3. To repair larger cracks, you may need to mix up a batch of high strength concrete patch. You can purchase this in small bags at a home supply stores or specialty hardware or pools stores. Make sure that you follow the manufacturer's instructions for mixing and do not mix too much up at one time. If you mix too much and it dries before you get it down, it will have to be discarded and a new batch will need to be made.

   4. Once you mix the patch to the right consistency, use a pointed trowel to force the concrete patch deep into the crack. Remember to smooth it out so that it looks good. This smoothing process can take a bit of time depending on big the crack is, which is another reason to mix patch in small batches, just enough to do what you have to do at the present time.

Once the patch fully dries usually overnight a concrete sealant should be applied to seal it up.
