How to Replace Pavers in a Pool Deck

Replacing pavers in a pool deck is normally no different than replacing the pavers on any patio or similar pathway. Sometimes they may be installed without mortar but this is rare due to its relative lack of durability. Having a proper, permanent installation fixed in place with mortar and then properly sealed makes the surface far more durable and watertight. Pavers can break if something heavy drops on them as well. In this case, the paver will need to be replaced. The following steps explain how this is done. The task should be easily accomplishable by anyone who has some basic DIY experience. Carry out this job in good weather when the forecast is set to be good for the day.

Tools and Materials Needed:

  • Replacement paver
  • Mortar
  • Masonry sealant
  • Wooden dowel
  • Trowel
  • Hammer
  • Chisel
  • Broom
  • Scrubbing brush
  • Wire brush

Step 1 – Remove the Damaged Paver

To remove the damaged paver, you will need to pry it up in pieces. If there is a large enough crack or hole in the paver to fit the chisel into, you should be able to pry up a section and take the broken stone out piece by piece. If this is not possible, then you will need to start breaking the paver up to make it possible to remove. Tap the paver in the middle with the hammer hard enough so that it cracks. Be careful not to damage the surrounding pavers. Remove all the chunks of stone using the hammer and chisel.

Step 2 – Remove Existing Mortar

Using the hammer and chisel, chip away the old mortar. This can be time-consuming and frustrating but it is important to remove all of the existing mortar. You will need a completely clean and level surface before you can install the replacement paver. A wire brush can be used to chafe away some of the smaller fragments of mortar which still remain. After that, use hot, soapy water and a stiff brush to clean out the area.

Step 3 – Apply New Mortar

Mix the mortar as directed by the manufacturer. The mortar should have a thick consistency. Apply this evenly and thoroughly to the cavity left behind by the old paver. Make the layer of mortar about half an inch thick. Likewise, apply a thin layer of mortar to the back of the replacement paver.

Step 4 – Set the New Paver

Gently put the new paver in place. Firmly press it down so that it is even and level with the surrounding pavers. Apply more mortar to fill the joints between the tiles until the installation blends in perfectly with the rest of the pool patio. Use a wooden dowel to pack the mortar tightly into the joints, making sure to wipe away any excess as you go. Leave this to set for a couple of days.

Step 5 – Seal the Repair Area

Use a masonry sealer to seal the repaired area. Follow the manufacturer’s instructions. Apply the sealer over the new paver and thoroughly over the joints. Allow this a day to dry.
