Distilled Water?

I don't use water. The water based acrylics will thin nicely with denatured alcohol. Sometimes they will thin with the 90% isopropyl or rubbing alcohol (not 70% though), but sometimes if you try using the rubbing alcohol the paint will shock like when you use lacquer thinner with enamel. You can get denatured alcohol at any big box home improvement center in the paint thinner dept. A gallon will last you the rest of your life, and only costs $20.00 US or so. I find that the paint dries much faster with alcohol as the thinning medium rather than water.

I've never tried using alcohol for thinning, but I've used it for cleanup and for acrylic paint removal at times. I'll give it a try as a thinner next time.
