Are they like pimples? If they are, its just where there is a small pockets of air behind, usually happens on roughing or reskim where its not completley sealed, all you have to do to get rid of them is give it a dry trowel when your wall turns brown

Did you double coat the wall?

if you hadnt mixed your plaster properly and it had lumps in it you'd know straight away mate, it'd do your head right in...every trowelful a lump! sort of thing that gives labourers a sore arse, if you know what i mean...

Sometimes if you go on with the second coat too soon you can get those.
Apparently it's caused by excessive water where you're pushing it into the wall it's trying to come back at you!

Most commonly seen when you go over a bonding coat when it isn't properly dry.
