How often repoint patio?

There is no set rule on how often to repoint a patio or either when to repoint a patio. Different patio sealers will have different lifespans. There are many factors that will affect the lifespan of your patio grout, from weather conditions to how often you clean the patio and more.

The right time to repoint a patio will be when you have noticed that the mortar that held the slabs together has started to crack, crumbled away or is riddled with weeds.

How to repoint patio slabs with cement.


  • Cement
  • Pointing bar
  • Mixing bucket
  • Stirrer
  • Trowel
  • Soft brush
  • Gun injection equipment
  • Pointing trowel
  • Grout rake

How to:

Step 1 – Pressure wash patio.

Clean the patio slabs to remove any staining, moss and dirt.

Step 2. Remove old pointing.

Use a grout rake to remove old pointing. Do this in between all patio slabs. Sweep away any residue and dirt. You can pressure wash slightly again to remove the remaining dirt and make the joints damp.

Step 3 – Create mortar mix.

Follow the product’s instructions on how to create the right mortar mix. With the help of a trowel, load mortar mix into gun injection equipment. You might choose to do it without a gun, use a pointing trowel instead.


Step 4.  Push mortar inside the joints.

Push the mortar mix inside the slab joints. Any mortar that goes on the patio slabs can be wiped off with a clean damp sponge. Any extra bits of mortar can be brushed off.

Step 5 – Keep it damp.

Don’t let the mortar dry out too quickly. After you’ve pointed the patio, let it sit for a couple of hours (depending on the temperature). If you see the mortar starting to get quite light, make it damp with a fine mist of water using a hosepipe. The next day, make it damp again with a fine mist a couple of times a day.

How to repoint patio slabs with dry mix.


  • Cement
  • Sand
  • Grout rake
  • Vacuum cleaner
  • Trowel
  • Broom

How to:

Step 1. Remove old grout.

Use a grout rake to remove old pointing. Do this in between all patio slabs. Sweep away any residue and dirt or use a vacuum cleaner to hoover any dirt or leftover residue more thoroughly.

Step 2 – Create dry mix.

Speak to a local professional for advice on the best dry mix ratio for your location. Mix it together until you have no crumbly bits of sand. You want to aim for a consistency that holds together when being squeezed. Use safety gloves when testing the consistency of your dry mix.

Step 3 – Push mix in.

Use a trowel to insert the dry mix into the joints of the slabs. Compact it down. Do this again until the mix is higher up and firmly compacted in. Use a brush to sweep any leftover dry mix over. Make sure to not leave any mix on top of the slabs as it might stain. Leave it to cure.
