Pfalzpaulianer11 Mar 2022 19:49Hello everyone,
We are now at the stage of planning the interior plaster. Our general contractor has offered a lime plaster as the base coat. It is important to us to have very smooth walls with as few visible shrinkage cracks as possible.
Therefore, we are considering using paintable glass fiber fabric.
My question is: The advantage of lime plaster is that it creates a good indoor climate and makes mold formation very difficult. If I apply paintable glass fiber fabric over the lime plaster and then paint, do the benefits of the lime plaster disappear, and could I just choose the cheaper gypsum plaster instead? Our general contractor would credit us 3000 euros. What do you think? Many thanks for your help.
We also have a ventilation and exhaust system, so I don’t expect mold issues. The masonry is insulated with Poroton blocks.
Best regards,
Pfalzpaulianer

Whether you then apply the painting fleece would basically depend on the quality of the plaster. What does the contract state? Q2 or Q3?
P.S.: Where is the Pfalzpaulianer from?

I can only agree with the previous speakers.
I find that gypsum plaster has a nicer surface, although you have to keep in mind that it is more sensitive to impacts and so on. There is also a gypsum plaster (Aquaprotect) approved for wet areas, which we use, for example, in hallways and stairwells of residential buildings because it is a bit more durable.
The standard case will be Q2. However, you should be careful here, because painting fleece can sometimes worsen the appearance of Q2 by making unevenness more visible. It is recommended to use Q3 for painting fleece or to leave it at Q2 and just paint.
Personally, I would also differentiate by room types -> representative rooms (entrance, open kitchen/living areas) Q3 + painting fleece and less important rooms (bedrooms, etc.) Q2 painted. If you apply the paint properly and with a roller in an opaque manner, the result is often quite good. But of course, as with all things, it also depends on the quality of the plaster.
If I were you, I would have prices compared again. The situation improves if you have Q2 plastering done and then the painter applies the Q3 skim coat. With Q3 plaster, very often the required quality is not actually met, which usually leads to a complicated discussion.
The option with Q2 plastering and Q3 skim coating is somewhat more expensive.
