What would cause these bubbles in texture

painttexture

I recently had a contractor out doing work on my bathroom, including re-texturing walls and painting.

When we 'moved back in', I noticed the walls are littered with these little 'holes' or bubbles and not sure what would have caused it.

Any ideas?

It's either poorly prepared compound or poor application technique.

I assume you're asking this because the are finished with the work. If that's the case, this is substandard work, in my opinion at least, and should be corrected.
