How to fill hole in brick wall after AC removal?

[malvinat]

hi there, just trying to find a product to fill in this hole after our split AC has been removed.

I have tried to obtain quotes but no one wants to do it.

thank you

Good morning @malvinat 

I had the removers just fill the hole with expanding foam a sit was at the top of the second floor wall and access was a pain.

With your issue, I would use some expanding foam first Sika 500ml Boom Expanding Foam Filler 

Then trim the foam so its around 10mmm bellow the brick surface and use

Selleys 440g Medium Grey No More Gaps Bricks And Mortar Gap Filler for the front facing surface.

I would practice on a piece of timber first as I think it could be a little messy to get right.

Welcome to the Bunnings Workshop community @malvinat. It's splendid to have you join us, and many thanks for your question about repairing a brick wall.
 

It is great to see you have already received a solid suggestion from Dave, and his approach will certainly work for this kind of repair. Using expanding foam is a good way to fill the internal void so you have something firm to build on, and trimming it back slightly below the surface gives you room to apply the mortar gap filler cleanly. A product like the No More Gaps Bricks and Mortar filler will let you shape and texture the surface so it sits neatly with the surrounding brickwork, and it is a very manageable DIY option.

If you were aiming for a completely seamless repair, the only true way to achieve that would be to cut out the damaged section and install a matching brick. That requires sourcing a brick close in colour and profile, cutting neatly into the existing wall, and repointing the joints so everything ties in. It is definitely a more advanced masonry task and usually best left to a professional. For most situations though, the foam and mortar filler method will give you a tidy, weatherproof result without needing specialist tools or bricklaying experience.

Please let me know if you have any questions.
