Filling in old socket boxes

[markymark2406]

Need to fill some old sockets with cement, what’s the best way to stop it fall it fal

Don't try and do it in one coat.

I believe that sharp sand will enable you apply thicker coats.

Alternatively using browning plaster.

I use the Mottie patented 'fling' method.

Might be worth putting a couple of concrete screws in to give it something to hold on to?.

Remember to Dampen bricks before putting in what ever filler you chose.

I cut some breeze block slices to the desired size and cement them in.
Make sure it's a tight fit.

Sharp sand is added where shrinkage is a problem (roof verges etc). It slumps and is harder to work with and some shrinkage wont be an issue as he'll be able to compact it and thoroughly dampen first.

We'd have some board adhesive on the go and we'd dab in some bits of plasterboard for deeper areas. We'd also point around any existing socket boxes with dab too. Good gear. Strong grab and doesn't shrink much.

When the labourer brings you a bucket of mortar over and it's got an inch of water on the top you know he's used the spreads sand. They prefer our sand if it wasn't for the cracking.

Thanks, I now understand why it is used on flaunchings.

So if the OP was to use plastering sand, would that make life easier?

Ahhh.. Google tells me that it is used where the finish needs to be smoother.

You can work it to a smooth hard finish, yes. Its impossible to work with in small amounts or point with.

A fatter softer sand is better because it is workable, less gritty and does not separate from the water as readily.

Building sand has more rounded particles and often contains impurities that produce a more workable mortar. When lime was used as the binder, sharp sand with more angular grains that had some of the loam washed out of it could still produce a workable mortar.
Lime suppliers sell building sand with sharper, angular grains. The shape of them lock together better than the rounded ones.
