ᐅ What steps are necessary to achieve a Q3 finish from a Q2 interior plaster?

Hi,

The general contractor will hand over the house with Q2 interior plaster. We plan to mainly do the painting ourselves or hire painters for it. Having the whole house painted professionally is quite expensive, so we are considering doing some of the walls on our own. We will have all the ceilings done by professionals because we want to install painting fleece there. The main question is: What exactly is required to bring a Q2 wall to Q3 level so that dispersion paint can be applied directly?

From what I have researched so far, at the very least, all walls should be sanded with a float or sanding block. However, this probably is not enough, and all walls would need an additional layer of gypsum-based finish plaster, such as a bonding plaster like Knauf Rotband (which I have read about frequently). Is this correct, or what do the experts here recommend?

Best regards

Why don’t you order Q3 from the general contractor (GC)?

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

A sufficiently thick base coat plaster and several sanding steps.

So, we also applied a fleece to the walls to avoid sanding and similar work. Why do you want to cover only the ceilings with it?

Our walls will also be finished to Q2 level, and the house price includes textured wallpaper. We are considering having the painter install paintable fleece instead of textured wallpaper. That is probably cheaper than Q3.

How much extra does it cost to upgrade from wallpaper finish to Q2, Q3, or Q4?
