Fluid Bed Painting

8 posts in this topic

I've been having a terrible time with the vulcanoes myself. I have about 120 different colors, and it seems that some colors work better in the bed than others. Do the fluid beds you buy get these vulcanoes as well? I'm almost thinking that if you were to use a smaller diameter PVC fitting, maybe 1.5" rather than 2 it would work better? Air is going to take the path of least resistance through a coffee filter, so if it has less opportunity to stray and force itself through the easy spots, maybe it would work better?

Don't you have a valve that you can use to adjust the air flow?

Have you tried something else for filters like brown grocery bags?

No I didn't try brown bags, I have a valve to control the flow, but still get them.... I'll try the brown bag!

I use vac filters, coffee filters and brown bags. I find different mediums work on different colors.

The vac filter sounds like a winner! I have plenty of them laying around too! Thanks for that one!!

I also have the same problem. I use the brown paper bags. Some paints work really well and some have terrible volcanoes. Some seem more dense .

Notes, notes, notes, the pigment sizes are different on certain colors so check to see what works and make a note of it as that is what you'll need to use more often than not for that particular color. Kinda likening it to the way airbrushes have different paint reductions or PSI for different colors in the same paint line.
