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

"Could be" or "must it be like that"? So with full-surface reinforcement mesh?

No idea, since only you know your current plaster. The contractor probably made their suggestions for good reason. You don’t want everything falling off the wall again just because there’s no reinforcement...

What is supposed to be a gypsum-cement plaster?

A primer is always necessary and should be applied separately. Reinforcement mesh with new plaster? I would get another quote...

We use lime-cement plaster, which sometimes crumbles. After treatment with a deep primer, it no longer crumbles, and the plaster also stops absorbing paint.

Two coats applied undiluted, and it looks fine.

In some areas, I still apply a thin skim coat, while in others we apply a finishing coat.

Oh, one more thing, the building is located in an Eastern European country. They still work in a very old-fashioned way here.

That’s the problem with this situation – nobody really knows what was actually applied to the wall and how neatly the work was done. Sounds like it’s quite an adventurous build 😉

Oh, I had only seen the first three posts – then the reinforcement does make sense after all...

What was applied to the wall, I already mentioned. And yes, the workers did a reasonably neat job. However, from my experience in our region, the walls are usually plastered, and if you don’t want wallpaper, they are skim-coated with gypsum plaster to create a smooth surface. WITHOUT full-surface reinforcement... which is why I’m asking...

The craftsmen here are not fully professional like back home, but rather self-taught. The explanation was that this is a new building, which might still settle a bit. That’s why they used full-surface reinforcing mesh in case settlement cracks appear. Although I tend to think that if a settlement crack does occur, it would just be skim-coated and painted over...
