What are pock marks? Do you mean air bubbles that popped? Post a link to a
picture if you can...If it is air you are talking about then yes that is
common when going over painted surfaces with a heavy coat of joint compound
and nothing will stop it .You just have to go back over everything with a
tight skimcoat when mudding which you can't do with texture. Maybe you are
putting it on to heavy .Lemon Joy was used by some to remove air from joint
compound over NEW drywall years ago (pre-power mixing , Gaint Potatoe Masher
days ..LOL) but never heard of using it with paint and texture
though.Doesn't mean it won't work but in my 20 years of drywall I've never
heard of it....Let me know how it turns out. Never to old to learn something
new...LOL
