Hello everyone,

the flower box (concrete) on the loggia had to be removed due to the renovation measures. It was connected to the masonry and now I'm missing about 3-4 stones on the left and right.

Because of that, I certainly won't be able to get a mason (assumption).

Now I think that inserting these stones can't be that difficult (or can it). I have never dealt with something like this before but would now dare to insert these stones myself. They are made of sand-lime brick (see photo), so I would now go to the nearest hardware store and get the matching stones including mortar.

1st question: do I need to pay attention to anything regarding the mortar for sand-lime brick?
2nd question: I read online that after completion you should remove some mortar from the joint to then plaster it finally (sounds logical, but what do I know) so is this how it’s done?
3rd question: should I better keep my hands off it altogether?

Thanks a thousand and best regards, Claudia

Plastering? – you probably mean "pointing". Masonry, which is going to be plastered, is not made "nice" beforehand. With exposed brickwork – as is present here – the wall is first structurally built up and then, while the joint mortar is not yet "hard," the joints are evenly scratched out and mortar is smoothed and refilled again. Google "Fugenglattstrich," then you’ll see it done with a hose piece.


There are mortars optimized for different types of stone. This has to do with the fact that mortar contains water and different stones absorb it to different degrees. However, I wouldn’t be too worried about three bricks, possibly just repairing a bit below the optimum. You’re not taking the master craftsman exam right away anyway.

But there should be construction sites nearby where you can ask a professional if they’d be willing to spend half an overtime hour for little money.

Just a quick update for those who are interested.
The woman does it herself with a little guidance (not pretty but rare).

Windows have already been delivered and installed. So the old dark balcony/loggia thing is a thing of the past.

It would have been nicer to fix it right away in the correct association, but for the beginning [emoji106]
