ᐅ Exterior Plaster: Mineral-Based or Synthetic Render?

Hello everyone,

The exterior plastering will be coming up soon.
The plasterer has now offered a dispersion-based render.

He personally prefers it because

a) the color is integrated directly
b) it is supposed to crack less

So, a question for the experts and homeowners who have already dealt with this topic:

Would you agree with these two points?
Is it really true that this type of render does not need to be painted afterward?

What drawbacks does dispersion-based render have?

Thanks for your opinions!

When I recently requested a quote for the exterior design of our house, I was told that a white exterior plaster is generally applied first and then painted over, as otherwise there is a risk of visible color inconsistencies.

Our plasterer said that with light colors, you don’t need to paint over the dispersion plaster, only for dark, intense colors is a coating recommended. Since we want white or a very light gray anyway, the dispersion plaster (in the corresponding color) would be completely sufficient.

But as I said, I am still basically considering and gathering information on whether to choose dispersion or mineral plaster...
