ᐅ Should you paint or wallpaper lime-cement plaster?

How was your base coat treated before painting? Was anything applied over the base render? Did you just fill and sand, and if so, with what material?

Hello Kinderpingui.

Unfortunately, this was some time ago, but here are brief answers to your questions:

• Before painting, only a quartz primer was sprayed on using a standard Gloria spray pump.
• The base render was simply "scraped off" by the plasterers at the end, resulting in a very light texture. We didn’t want it smooth. This also prevents visible "problem areas," as they are less noticeable with this texture.

Ok. Thank you for the reply.
Was your base plaster applied so smoothly that there were no voids or bulging areas at all? How did you fill any voids?

The base plaster, as far as I can remember, was also the final surface.
After a certain drying time, it was simply floated with a trowel and some water.
Just try searching for "lime cement plaster floating" to see what I mean.

I’m not sure what "Lunker" refers to, but if you mean dents or holes, we haven’t noticed any so far.
Also, no bulging areas—at least not under normal lighting conditions.

The advantage of this floating technique is that it reduces the visibility of unevenness compared to completely smooth wall surfaces.

We recently replastered the first room ourselves, using a lime-cement plaster. After it set, we smoothed it thoroughly with a float, then did some rough filling, applied a primer, and finally wallpapered. Our daughter wanted a feature wallpaper, and the rest of the walls were painted yellow, so we put up the feature wallpaper and applied fine woodchip wallpaper on the other walls before painting them with ordinary emulsion paint. We didn’t do extensive filling since the floating already gave a pretty good finish. We are happy with the result and plan to do the same for the next room.

After it started to set, we thoroughly smoothed it with a trowel, then roughly skim-coated it, primed, and finally wallpapered. Our daughter wanted a feature wallpaper, and the rest of the walls were painted yellow, so we applied the feature wallpaper and used a fine textured cellulose wallpaper (Raufaser) on the other walls before painting them with a standard dispersion paint. We didn’t do extensive filling since the smoothing was already quite good from the troweling. We are happy with the result and plan to do the same approach for the next room.

Thank you. What exactly did you use for the rough skim coating? A special filler for lime-cement plaster or just the base plaster?

I need to check again, but it was definitely a standard wall and ceiling filler from Sakret.
