How to patch internal concrete wall?

Benk

I have an internal concrete wall to patch and repaint. The holes on the walls range from a few mm to 100mm in diameter.

It's likely you'll be able to use a masonry filler product like this Polyfilla Exterior Brick and Render Masonry, but if there is more complexity to the issue, then this product may not be suitable.

Do you have any photos you can share of the patches?

How deep are the holes?

Is it likely you'll need to add a backing to prevent a filler falling through?

Let me know what you think.
