Plastering and Joints compound coming off

I recently did some plastering and joint compounding and when I primed the wall it began coming off onto the roller. The plaster was definitely dry as about nearly 2 weeks went by before I had a chance to prime it. I though maybe it was cheap plaster but it was recommended by the store.

Any Ideas? thanks

what compound did you use, was it applied to new drywall?? My understanding is that you filled the joints and taped with premixed mud? and then skimed the entire surface with plaster?

Baggs put down his joint-compound encrusted roller and said:

If wall surface was previously painted, be sure it is clean, grease and dust free before plastering/joint compounding. I always wipe down and pre-prime suspect plaster surfaces with a good oil-based interior primer before patching.

I can't remember what compound I used as I did suspect it was the compound so I disposed of it and will not use it again.
To answer your question it was applied to new drywall using premixed mud. But a never skimmed the surface with plaster.

thank you,

Merry Christmas

if the compound had been opened & allowed to dry out, or if it had ever froze, it'll crumble off the wall.
