ᐅ Wall construction without wallpaper

Hello everyone,

I have a question regarding the interior wall construction WITHOUT wallpaper. At the moment, the masonry and plaster (a type of sand render) are completed. I would like to apply a fine plaster/spackling compound that can be painted directly (without wallpaper). A company (whether professionals or not, I’ll leave that open) recommended and offered me the following steps:

1. Primer
2. Reinforcement mesh applied extensively on the walls
3. Gypsum plaster applied extensively as a finishing coat
4. Primer
5. Latex paint

Aside from the latex paint, which I do not want, I think step 2 might be unnecessary. So, primer, then gypsum plaster as a finishing layer, primer again, and then dispersion paint...

How would the experts here evaluate this approach?

Regards and thanks in advance for your input

Why didn’t you have the walls finished directly with gypsum plaster at Q3/Q4 level? It can then be primed and painted (or have painting done) right away.
What type of plaster did you have applied – as a layperson, I’m not familiar with something called sand plaster... Therefore, I can’t really comment on the next steps at the moment.

I think it would be important to know what type of plaster is currently on the wall...? Otherwise, the question is quite difficult to answer.
Is it not possible to paint directly over the existing plaster?

Our structure is as follows (from the inside, "bottom" to "top"):
1. Brick
2. Gypsum-cement plaster
3. Two coats of silicate paint, mixed with primer and water (first coat 20%, second coat 10%)

So, no primer, reinforcement, or anything like that at all...

The background is as follows: it is a finished apartment with a base coat plaster, electrical wiring, heating installation, and screed. I had no influence on the plaster. These are the services provided by the construction company. Everything else is now up to me.

The plaster is a rather rough lime-sand plaster: 75% lime, 25% sand, and water. It cannot be painted directly. A finer layer is needed on top to achieve smooth, paintable walls.

Oh, and one more thing: the building is located in an Eastern European country. Work is still done in a very old-fashioned way here. Workers operate on unstable wooden structures, wearing sandals and torn clothing. Safety measures and proper tools are largely unknown (even though the local hardware store has everything you would find in our hardware stores).

And the walls are still made of the red fired bricks, roughly assembled (30 cm (12 inches) wall), and on the outside there is insulation with styrofoam and reinforcement with plaster. Due to the slightly uneven walls, the plaster on the inside is 2-3 cm (1 inch) thick.

Then the proposal with points 1-4 plus painting might actually fit quite well.
