I've got a brick and block wall in my kitchen,
if i paint it now with masonary paint
will it be easy to plaster over it in a few months or years?

Or would I be causing problems?

You might be okay scoring/scratching the painted surface to key the plaster to the brick, but it's probably a lot of extra unnecessary work.

IME artex will stick where plaster may not want to (plus it's a lot easier to use)

But artex is the spawn of the devil ;-)

I am not a plasterer, but I've seen underlying paint blister when
plastered over. Sometimes the bubbles dry back, sometimes they don't...

PVA is the usual way - check it's sound, if not, wire brush then PVA

Its the way plasters would "glue and set" a painted artexed ceiling for
example. Knock of the highest spots mechanically, roller with PVA, and
the plaster onto it while still tacky.

(note this is for a skim coat - might not work so well for a full base
coat of plaster!)
