What steps are necessary to obtain Q3 interior plaster from Q2?

Hi,

we receive the house from the general contractor with Q2 interior plaster. We would then mainly want to paint or have it painted. Having the painter do the whole house is quite expensive, so we are considering doing some of the walls ourselves. We will have all the ceilings done, as we are also having painter's fleece applied there. The actual question: What exactly is necessary to achieve a Q3 wall from the Q2 in order to apply dispersion paint directly on it?

According to previous research, at a minimum, all walls should be sanded with a float or a trowel. That certainly won’t be enough, and all walls would have to be skimmed again with gypsum plaster, such as the Rotband bonding plaster gypsum from Knauf (I read this often). Is that correct, or what do the experts among you recommend?

Best regards

Why don’t you order Q3 from GU?

We are having all the ceilings done because we are also having painter's fleece installed here.

Not a bad decision; fiber fleece is not that easy to handle.

The actual question: What exactly is necessary to get from a Q2 wall to Q3 in order to be able to apply dispersion paint directly on it?

A reasonably thick base plaster and several sanding processes.

Rhenish regards

so we also have a fleece on the walls because that eliminated the need for sanding etc. why do you only want to cover the ceilings with it?

Our walls will also be Q2 and [im Hauspreis] then includes [Raufaser]. We are considering having [Malervlies] applied by the painter instead of [Raufaser]. It is certainly cheaper than Q3.

How much is the surcharge from tapezier fertig to q2, q3, or q4?
