How to repair holes after chasing in brick wall?

[Skogssus]

What is the smartest method to fill holes in a brick wall after chasing for cables? Just mortar or sealant/foam first? The surface of the entire room will then be skim coated and painted.

Use regular practice and line the bottom with it, pipes can be attached to the bottom by driving two nails in a cross at a few spots, so it stays in place.
