Hello.

The construction mistakes of the 1990s are becoming increasingly obvious, quite literally. That was when the insulation boom began. We would have liked to apply a decorative plaster finish, but unfortunately had to quickly choose a painting company whose workers were not aware of the long-term effects of their methods. The insulation boards were fixed with what I would call plate anchors. Coaster-sized plastic discs held the insulation boards on the wall. Nowadays, these are usually glued.

It is clear that white plaster will darken over the years. However, due to the different material densities (plastic, base coat, and paint), numerous round spots become visible through the plaster around the house, which is also affected by green algae stains.

Now there are the following options. Continue living with it... could you do that? I would really be interested to know. Or redesign the facade. It might not be possible because of the insulation boards, or only feasible with high technical effort. Perhaps by using slate or brick slips (slates or facing bricks). Or replastering. Is there a plaster thick or dense enough to completely prevent the “plate anchors” from showing through again?

Regards, Sauerländer

I know. 😉 I was also aware that this comment would come up, but I don’t want that. I ask for your understanding. Even writing the request brought suppressed feelings back up. 🙁

Plate anchors are still used in the same way.
We have a similar problem (although the plaster is only 3 years old, it was done very poorly, had to be patched everywhere, so it is basically a patchwork), and I’m not confident enough to replaster. There’s also no money for that. So, we will use thin brick slips. They look like traditional bricks but weigh only about 5 kg per square meter (11 lbs per square yard). I’m confident I can handle the adhesive application myself. And they really look good. These thin brick slips are offered by various companies, for example Brillux, Caparol, or Elastolith.

Are these sealed with grout, or how does that work? Don’t they crack when the polystyrene expands and contracts at different rates?

Flat facing bricks, thanks for the tip, I will look them up right away.
