Asking for advice before masonry

[Pelotard]

Posting a quick question here in reliance on all the expertise and wisdom available at BH.

I am planning to build a “wall” of lecablock behind a narrow stove and an electric stove that stand next to each other, i.e., between the stoves and the back wall, which is the chimney stack, up to the same height as the stoves. To get that distance and surface behind the stoves.

Under and between the lecablock, I will use mortar B in the usual way. (There is a stone surface underneath.) But how do I manage between the new leca wall and the wall/chimney stack? That surface is plastered and flat. Should I try to put mortar there as well, as thin as possible? Or is there something else that would be better? Or should I simply not have anything between there?

I would be very grateful for some good advice!

The bruk will not adhere very well to the plastered surface, but if you want it to adhere better, you can use dowels in layers with suitable iron, which is then embedded in the new block layers. If there is air in between, just fill with bruk.

Does dubbing in shifts mean drilling in reinforcement bars or something in the chimney stack, or?

Does "dubbar i skiften" mean to drill in reinforcement bars or something in the chimney stack, or?

Yes.

ok, thanks!

You might think that it may be a bit overkill to dub. There won't be any forces in any direction on this "wall" (except for gravity, straight from above), it's just supposed to stand there. Maybe one could "glue" the blocks to the wall when building, with some type of compound?

Rex fix or other fix works well for gluing.
Use a notched trowel if you have one, 10mm.
