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.

Try adding more or less water to the mix. Make sure that your spray is "mixed" when using it (Don't let it sit for more than 30 minutes. If it does, mix it again before use).
Don't spray too close to the surface.
Lastly, another option to consider, is to use a smaller spray nozzle head.
When mixing, do you use low speed? I was in a rush and mixed at a higher speed and had to remix a few times to get right consistency. I think I may have also sprayed too heavy on the wall as pock marks tend to occur where splatter was sprayed over when overlapping spay as recommended in texture machine manual.
