I sprayed drywall texure for orange peel finish on walls using a
larger texturizing machine over a wall that had been previously
painted and primed. When texture dried, I noticed that there are
several pock marks in the texure. It is like the spray blotches caved
in in many areas when the spray texture dried. I have never had this
happen before. I was using a Graco RTX1500 that is much more powerful
than hopper/compressor outfit I have used before. Anyone have this
problem when spraying texture and if so, what causes this and how did
you take care of problem?

I have read through post and did not see anything about pock marks in
the actual spray texture on walls. Adding liquid dish detergent to
joint compound was suggested (or a commercial product) for eliminating
pock marks when taping and coats prior to spraying texture, but did
not see any reference to pock marks in the actual texture. Would
adding dishsoap help when applying the orange peel texture or would
this interfere with paint.
