With the kitchen renovation, a new fan came in, and I needed to move the hole in the chimney breast a bit. That is, I widened the hole to the right. Unfortunately, I couldn't make the hole very deep, so the plan is to seal the old part with about 2 cm thick bricks. Over the hole, behind the cover plate, I plan to place a plate with a matching hole for the hose and some sort of "frame" behind, into the hole, so that I have something to mortar against.
Now, I've only done masonry once before, and that was outdoors, with dismal results. Initially, I thought of asking a mason to come and slap on the stones, but the more I think about it, the less willing I become. What would a mason charge just to come out to us, splash on some mortar, and pop in the stones? Probably wouldn't take more than 20 minutes and would surely cost over two thousand (pulled out of thin air). Besides: could save some cash.
Is it necessary to prime beforehand? Scoop under and on the side of one stone, press it in. Scoop on the side and top of the second one as well as the top of the first one that's in place, and press in the second one? How do I make it work well with my little construction that's going to be mortared in too? It's so little that will be visible later, but I want it sealed.
Any tips. Or anyone skilled near Örebro who’s up for a cup of coffee?
You can't see much in the picture, but it was what I had where I am.

Will the result be visible or hidden? If hidden, it's basically as you say, "slosh on" what is needed, reinforce with pieces of old bricks.
You should preferably place the pieces in a bucket of water for a couple of minutes so that they can absorb water. Likewise, you'll need to water the existing wall quite thoroughly, so it doesn't draw all the moisture out of the mortar. If the mortar loses moisture too quickly and doesn't have time to set, it will become brittle and fragile. In other words, pre-water thoroughly.
Mortar B should probably suffice for the task, along with some trowels from byggmax.

Thank you for the response. A small part will be visible, maybe 7 cm. What I'm most worried about are the seams, making sure they look nice.
don't worry about the joints when you are laying bricks.......just make sure there is mortar in them and then once they have settled a bit, take a scrubbing brush and run it over the joints.
Okay, that sounds good. I'll probably try it over the weekend. I'll get back to you on how it went.
