ᐅ Timber frame construction, level 2 skim coat – breathable interior plaster

Hello everyone,

We are building a house using timber frame construction, with Q2 level skim coating.

For the interior design, we want to use breathable interior plaster applied by rolling.

We have chosen a branded product, Knf Esiputz, in fine grain.

Since all interior walls are made of gypsum drywall panels, which are known to be very absorbent, we need to prime them.

The question is whether we can use a standard primer or if there is a better alternative. The information we have gathered is partly contradictory. What are your experiences, or what would you recommend?

Best regards

I'm not a professional, but I'm planning to do exactly the same. So mineral plaster in good brand quality and a basic primer. I think you just have to try it out in one room first...

Just use the primer recommended by the respective plaster manufacturer. The price differences aren’t that significant. For the entire house with 170 m² (1,830 sq ft) of living space, I probably needed about 25 liters (6.6 gallons) of primer for walls and ceilings.

Hi, the primer must definitely be completely dry, possibly applying two coats, especially on the corners.
Plastering should be done at a room temperature between 18 and 22 degrees Celsius (64 and 72 degrees Fahrenheit) and avoid drafts to ensure the surface dries evenly.

Thank you for the professional answer!

Stir the plaster well from time to time; you will develop a feel for it. Take your time, it will work out. You can also practice beforehand on a drywall panel, for example, applying with a trowel and wiping crosswise with a large damp glaze brush, etc., using only light pressure.
