ᐅ Plastering work in Q2 – painting work to follow?

Hello everyone,

Starting tomorrow, our interior walls will be finished with Q2 plaster.

We will carry out the painting work ourselves a few weeks later.

Now we are wondering what would be the best option for this.

We have currently considered several options but are still unsure which one we prefer (cost/effort).

1. Simply paint with EasyKnauf roll plaster (fine texture)
2. Apply painter’s fleece underneath and paint with EasyKnauf roll plaster (fine texture)
3. Apply painter’s fleece underneath and paint with standard emulsion paint
4. Use textured wallpaper (Raufaser) and then paint over it

We generally don’t like ceilings and walls to be completely smooth – a fine texture is perfectly fine.

What have you done in similar situations? If it wasn’t a DIY job: What did your painter do?

Any tips/tricks/notes on this?

We are also facing the decision and thinking about which approach offers the best value for money.

@Benutzer200 could you possibly upload one or two photos of your wall/close-up shots? I can’t quite visualize it.

Sure – white, gray, and yellow (the colors don’t come through well in the photos), wall distance about 15cm (6 inches):

Thank you! That looks great.
And did you follow the method described by Prager91?

Applying a (base) scratch coat over a Q2 plastered wall and then finishing with the quartz plaster?

Why the base coat? Because it's less expensive than applying quartz plaster twice?
And which brand did you use? Also Haering?

And you worked as described by Prager91?

I applied two coats of Haering. I hadn’t even considered using a different base render. In my opinion, the base render needs to have a certain texture or grain; otherwise, the Haering won’t spread evenly. After just one coat, the result didn’t look good...
But I was working on an existing surface, not new construction. In the end, that doesn’t really matter. It was old plaster (which had been damaged by electrical work and then smoothed out by me). The finish level was somewhere between Q2 and Q3.

I ordered everything from the painting supply store; Haering isn’t expensive enough for me to try saving 100€. Especially since I used pigmented plaster. That requires two coats for sure. Overall, it’s probably cheaper than base render plus Haering plus paint.

I ordered everything from the painting supplier; Haering isn’t expensive enough for me to save 100€. Especially since I used colored plaster. With that, applying two coats of paint is mandatory. Overall, it’s probably cheaper than base coat + Haering + paint.

Our plasterer applies a base coat WITH grain, so that the Haering texture coat only needs to be rolled on once, and is then painted with STO Rapid Matt.

I think this is probably better/cheaper than applying the “expensive” textured coat twice. But I don’t actually know—that’s just a guess!

My plasterer also said that the base coat is important for adhesion—it basically acts as a primer.

I will definitely look into that, and would like to adopt this method, avoiding the cheap option of just applying the textured coat and then creating texture with a roller.

How difficult would you rate this plasterer’s method for a layperson to do, considering you mostly did it that way yourself?

I think this might also be cheaper than applying the "expensive" rolled plaster twice. But I’m not sure – just a guess!
I don’t think so. Just the fact that you have four separate work steps will make it more expensive. Normally, your plasterer should prime before the base coat as well as before the rolled plaster – then there are only three steps. And the paint (just white? how dull) is not a cheap product either.
Material costs for 120 sqm (1,292 sq ft) living area – all walls (including a large part in the bathroom/guest toilet) – were about €750 last year, plus paint rollers, masking tape, etc.

Can you use a paint roller and paint walls? If yes, then you have sufficient qualification 😉 The Haering plaster is – to put it bluntly – just thick paint mixed with fine sand. Use a long-pile roller (slightly moisten it before use) and you’re good to go.
