ᐅ EIFS dark color unevenness issues?

Hello everyone,

Is the result (see photos) really acceptable? What criteria are used for evaluation?

About four weeks ago, the façade work was carried out. External thermal insulation composite system (ETICS) with polystyrene insulation, fine-grain colored render, followed by two coats for "evening out," installed as a complete system by a professional company. However, the result is very uneven.

The specialist company rejects the defects, stating that this is normal for dark colors and that the work is done manually, not by machine.

To us, it still looks bad and incorrect. Every wall looks like this, regardless of the time of day. But is this actually a defect?

Thanks in advance!

It is difficult to assess. With dark colors, it is really quite challenging. You can clearly see the scaffold layers here, as that’s where the coating must be applied in sections. Still, I would have expected more with two coats.

From this viewpoint, it looks unsatisfactory.

The assessments are “under diffuse light from the usual viewing angle and distance,” meaning from where a user would typically view the house, for example from the terrace or garden.

I would also recommend hiring an expert to possibly measure the reinforcement thickness. It almost looks like you can make out the joints between the panels, but that might be misleading due to the roll marks.

I believe the money spent on an expert is well invested. However, you should look for someone specialized in façade surfaces, especially in ETICS (external thermal insulation composite systems). Otherwise, a generalist might not have the right expertise.

In the Hanover area, I could recommend someone, but you probably live in another part of the country.

Best regards,
Jann

How do you shade the large window areas?
It faces north, and we only get direct sunlight until about 9 a.m. at the latest. We assume that shading will not be necessary.

The plasterer back then also created a clear stripe all around our house.
We also discussed scaffolding. But it was painted three more times after the scaffolding was removed. It looks even worse now.

Really stylish, also the color. Could you please specify the exact color?
The color was mixed similar to RAL 7021.

However, the color is not very well accepted in the neighborhood...

Thank you very much for your very competent answer. We will definitely hire an expert. Unfortunately, we have to wait for the appointment, and the final invoice is already due.

Then you did it exactly right – I really like it, the whole house by the way! Looking forward to more pictures and information!

A house is a matter of personal taste; I can understand the neighbors since it is very dark. I don’t find it attractive. But it is your house, after all. Still, you might want to think about simply painting it a lighter color.

However, the workmanship is poor, and there is no room for discussion on that.

...and why should it concern my neighbors what color I paint my house? I don’t like the color of their teeth either.

Exactly, nothing. He just has to live with it. The green and purple houses back in the day were also horrible to look at. Now it’s just black.
