Filling internal masonry holes

[Vulcan]

I have a lot of 8mm internal holes (from screws) to fill for a solid/masonry wall. What's the best solution to fill them? I don't just want to use filler as it's largely a cosmetic finishing product.

I have seen this recommended before: https://www.tetrion.co.uk/product/hard-as-rock-filler-2/

But it only fills 10mm, but it's a better option than polyfilla.


Anyone used injection resin? It's not necessarily what it's designed for, but would be easier to apply:

Ive used two part epoxy cement resin very similar to what you linked, worked very well for filling masonary holes between bricks and doesnt shrink. it dries much harder than any filler though so bare that in mind if you want to sand it as its effectively meant to anchor in high strength fixings.

So I'm probably on the right path then. I was hoping if I used resin I would be able to fill it all but the last 5mm, then use normal filler for a sand finish.

Chemical cement ( injectable resin ) has the consistency of thick cream, sets in minutes, and looks like a greyish mortar when set. It's ideal for permanent repairs in brickwork where you need a mortar looking type repair that is completely weatherproof. It is resin based so it does not come off easily. You can happily just squeeze out some and mix it on a piece of card and apply it with a small tool rather than using the nozzle. If you want a neat finish and you haven't used it before then I would recommend placing masking tape around each hole to make sure you don't get it all over the place. Have a roll of kitchen tissue handy to clean up any mess quickly. Leave the masking tape on until the resin starts to set a little then it can be removed easily without making a mess. Once set you can paint it if you need "brick colour" or just leave it as is.
