How to Replace Damaged Brick Slips

While brick slips are extremely durable and will really stand the test of time, there are instances where they can be damaged. The damage could include an unsightly chip that looks out of place or a cracked brick slip that detracts from the overall finish. However, if you do find that you have a damaged brick slip, the main thing to do is not panic.

The good news is that a repair is cheap and easy and it doesn’t take long to complete either which means you can have your wall looking brand new again.

However, before you carry out the job, you need to make sure you take care of the prep work beforehand.


What Tools Will You Need?

To remove the brick slip, you’ll need to have the correct tools. This is an intricate job and you’ll need to make sure that you remove the damaged brick slip without damaging the brick slips around it.

So, what you will need to remove the brick slip is:


  • Hammer
  • Chisel
  • Flathead screwdriver/mortar rake
  • Tile adhesive
  • Pointing mortar
  • Spacers
  • Pointing gun/pointing trowel
  • Brick jointer


How to Begin the Job

A successful job will need you to take your time but before you can remove the brick slip, you’ll need to remove the pointing mortar around it.

To do this, you will need to slowly use a small chisel, flat head screwdriver or a mortar rake around the damaged brick slip. This will enable you to remove the mortar completely, helping to isolate the damaged brick slip.


Removing the Brick Slip

With the mortar removed, you can then begin to look at removing the brick slip. This can be a time-consuming job as it will need you to take your time as you won’t want to damage the surface beneath.

You can use a hammer and chisel to try and break the brick slip into sections. Once you break through the brick slip, you can then use the flathead screwdriver or the chisel to get underneath it and to the adhesive behind.  It is then possible to gently and slowly work the screwdriver or chisel through the adhesive. Once the adhesive has been broken, it will enable you to remove the brick slip in sections.

You will then be left with the remaining adhesive that will need to be removed. You should look to remove as much of this as possible, taking the wall back to the base surface.


Fitting the New Brick Slip

To begin, you should apply more bonding primer to the area. This will help the tile and the adhesive to bond to the wall. Once this has dried, you can then add tile adhesive to the area and put spacers in place to ensure the new brick slip lines up correctly. Once this has dried and the brick slip is in place, you can then begin to put pointing mortar around the brick slip using the pointing gun or pointing trowel.

Once the mortar is in place, you can use a brick jointer to finish the mortar and give it a good finish. All that’s left to do is to wait for the mortar to dry before standing back and looking at how good a job you have done!
