Brick up a doorway

[perkaby]

Hi,

I am planning to brick up a doorway in the basement. I thought I would use lecablock/lightweight expanded clay blocks. The wall is plastered and the total thickness is 9 cm, with about 1 cm of plaster on each side. My idea was to use 7 cm thick lightweight expanded clay blocks, but it seems like these are not in stock at the local building supply stores.

Do you think it would work to use 9 cm blocks and then apply a thin layer of plaster over the entire wall to make it even? Or is there a risk that the plaster layer will be too thick on the already plastered wall or too thin on the new wall section?

The opening is about 70x200 cm.

Should reinforcement be used?

I would avoid adding an extra layer on the remaining surface as it is more work, probably needs to be cleaned and primed beforehand, and maybe even sanded if it is painted. Order sjuor from the hardware store instead. Reinforcement is usually not needed.

Significantly easier to brick thinner in the door opening when you have natural edges to tear the plaster against. If you can overlay light concrete with thin joint mortar, these are available in the thickness you need.

Thanks for the response, that's what I suspected! I'll try to find thinner blocks or lättbetong!

Look for a better hardware store. At my local one, they have 70mm.

Possibly, one might have chipped a bit in the old plaster and netted to avoid a joint crack.
