How to patch holes in external stucco wall?

tjc888

Hi there,

I'm after some advice about patching up our external stucco wall after our air conditioner was taken out. The larger hole in the first pic has a cavity behind (about 10cm deep). For the bigger holes am thinking of putting some wire mesh, foam, then polyfilla. The smaller holes aren't too bad. The third pic has a plug the top currently.

Any thoughts or advice would be greatly appreciated – I'm new to all this and would love to learn some skills!

Cheers!

Hi @tjc888,

A warm welcome to the Bunnings Workshop community, it is wonderful to have you with us.

For the cluster of holes with the large one in the middle, I would suggest chipping away the render so you can apply this Pfeiffer Wall Patch over the holes, so it sits beneath the surface of the render. Make sure the surface is relatively smooth so that the patch can adhere well. Once the patch is in place, you can render over it using How to repair a rendered wall by @Nailbag as a guide.

For the smaller holes, you can just fill them with Polyfilla 500g Exterior Brick and Render Masonry without any additional work.

Once dry, paint the patches to match the rest of the wall.

Let me know what you think and if you have any further questions, please don't hesitate to ask.

Jacob
