Some questions for the experts

Feb 25, 2005 2 Replies

I am using an Iwata Eclipse double action brush that I use with Createx water based paints and cannot seem to get consistent patterns from the brush.The brush will spray great, stop, spray, or only spray when the nozzle is nearly wide open! Opaque colors spray better than the pearls but even these have their problems. I rinse the brush with hot water between paints until it seems to be spraying very well. I clean the brush throroughly between uses.


  1. Createx claims the paint can be used directly from the bottle is this true?


  1. The pearl createx paints spray horrible! Will it get any better if they are thinned? Will the pearls ever spray as good as the opaque paints?

  2. What PSI should I be spraying at and will this vary for the pearls versus the opaque paints? I can spray black and orange at a low PSI but pearls will barely come out of the brush at this pressue.

Thank you for any suggestions!!

I think you'll find that the nozzle orifice on the Iwata is just a bit too small to let the pearl particles through reliably. That, and the fact that acrylic paints are notorious for drying too quicly on the tip of airbrushes could be causing your problems.

The fix? Try to get a larger air cap/needle set for the Iwata (or get an airbrush with a larger nozzle orifice), thin your paints a little more and keep a cotton bud (Q-tip??) full of thinners handy to clean the tip of the 'brush when it stops spraying effectively. Just make sure that you pull the needle tip outta the way before you start swabbing away... You could try a bit more air pressure, but I think this'll just add to your problems.

What nozzle size are you using ?
