How to remove peeling paint from exterior brick wall?

Hi, we bought this house with whole exterior bricks has been painted but it is starting to peel off. What’s the best way to remove the paint? is it possible to do wall cladding over it?

Hi @mej711antones,

Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Working out why the paint is peeling should be our first step. There is no point in repainting the bricks if there is an underlying issue that has not been addressed.

Is this an isolated patch where the paint is peeling? Or are there other areas where the paint is peeling?

Have you had any issues with dampness in the walls? Does the brick that has very little white on it feel damp?

It looks like the brick may have been limewashed before it was painted. Is the white stuff on the bricks powdery?

If the issue is isolated and we can confidently say whatever caused the peeling has been handled, there's no need to remove the existing paint. You could simply repaint the section of paint that has peeled off with a suitable colour-matched exterior paint such as Dulux Weathershield or Taubmans Sunproof.

I'm happy to assist further once you've provided a few more details about the peeling paint.

Hi @mej711antones,

Regarding the cladding question — yes, it is possible to install cladding over the painted brick, but there are a few important considerations. To do this properly, you'll typically need to attach timber battens to the existing brick wall. These battens create a gap between the brick and the cladding, which is crucial for airflow and moisture control. Further details will be available in the installation guide of the cladding that you choose.

The air gap helps to prevent any trapped moisture, which could lead to issues like mould or deterioration of the cladding or underlying wall. You’ll want to ensure that the battens are securely fixed and that there’s enough space for proper ventilation. If you’re in a climate with high humidity or rainfall you might need to also use a vapour barrier.

Please let me know if you have any questions.

The brick wall was painted over 10 years ago. I think the peeling was due to age and poorly done. Most of the lower part of the external wall of the house paint is peeling.
