Crumbly plaster

exteriorplaster

I'm in a new build, timber frame house with the back clad in plaster.
The plaster seems quite "sandy", if that makes sense. If I rub it my hand comes away dusty and gritty.

Around one window I can see the plaster being a little crumbly. Is this an issue I should raise with the management company?

Yep, @DaveM is correct: That’s stucco. I live where it’s a “wet climate”, but contractors still try to use stucco from time to time.

Two problems: 1) no metal trim (screed) at the bottom of the stucco, and 2) mixture is improper if it’s deteriorating this quickly.

Here, we don’t use stucco much, so every time someone tries, it’s a disaster because they’re not accustomed to using it. Looks like the same where you live.
