Hi folks - is there a filler product I can use to fill a hole in a brick wall, that I'll be able to drill into again? I was mounting a baby gate and drilled a hole using the wrong bit (metal instead of masonry, see pic below). The slippage made the hole slightly too wide, and I don't really want to put the holes in a different spot.

I guess alternately, I could place a piece of wood as a post over the holes like below , then mount the brackets to the wood instead of directly to the wall.

Any thoughts either way? Would be great to know if there is a drillable filler anyway for when my weekend warrior self decides to drill some more bad holes.
Thanks a mill 🙂
Danny.
