Filling Very Small Chase

[LennyM1984]

I've chased a few cables into the wall that were previously in trunking. The previous owner had the ring extended to add a load of surface mount double sockets on the worktop near the sink and I am dropping this behind the cabinets and retaining just the one socket that currently feeds the fridge). The chase is only about 6-7 inches long (from the original socket down to below the worktop).

Can I just fill it with some mortar repair cement that I have kicking about? I don't really want to go out and buy anything else for such a small area and I don't have any bonding plaster lying about.

Toupret will do the job just fine.

It depends whether you want a perfect repair that won't ever show when finely painted, or at the other extreme, you're going to tile over it?

For best results, repair like with like is good advice, but not always needed.

If your left-over is cement based you won't get a smooth finish, so would need a very light surface coat of any indoor filler, sanded, for a smooth finish.

It would be easier and quicker to buy a small box/tub of (any) indoor filler which would do the job better.

If using standard interior filler then do it in a couple of stages. It will dry better and you can finish with a thinner top layer to sand to smooth.

Sorry my original post wasn't remotely clear. I'm intending to finish it with filler/skim but just wanted to see if I would have any issues making up the depth of the chase with mortar rather than bonding (we have surprisingly thick plaster!).

I've done it now so hopefully won't have any issues!
