We've run into something new, yea, like that never happens. Paint coming off brush handles. We've had a couple of interior mural projects where we have been using a combination of latex and artist acrylics. Some of the brushes have had the paint popping off the handles I've never run into this one before Oh, I'm well aware that laying a brush down in a tray of lacquer thinner is asking for it, but water??? The brushes in question are various "artist" brushes. Some do it, some don't. Oh, and the really cheap ones that you get in a package of thirty or so for $5 are fine, it's the expensive ones that the paint pops off of

Do you think those handles are "dip coated" from the factory, and when you put them in water, the wood swells slightly and cracks it? Then when it dries and shrinks back, the coating falls off....
Hey.....it could happen.....
Have a great weekend, George

Same thing here. I would keep my acrylic artist brushes in a pan of water all day to keep from drying out when working on a big project and the paint would just pop right off the handles after a while. Dale's gotta be right about the wood swelling.
Bluz Boy Bill Diaz taught me a trick when we where working with Nova Color. Put the brushes in acrylic retarder to keep the paint from drying in the brush... Just like you would with oil on a lettering brush. This will keep them wet for a day or so until you have time to clean them.

I always have a bucket of water alongside me when working with waterbased paints. Just drop the brushes in to stop them drying out until cleanup or reuse. (Same with the airbrush.) Never had a problem with any kind of brush!
But then I use pure rain water from my house tank. What's in your water? Acid?
Anyway what's the problem with a bare handled brush? My set I use for inks are as naked as the day before the handles where painted because of the lacquer thinners I use.
Do you need to know what brand and size a brush is before you use it? If it looks right, go for it!

It may not be the wood swelling and shrinking, but the water getting underneath the acrylic paint. I had an acrylic painting on canvas one time that I put on a high shelf to finish drying and store away. The roof developed a leak and soaked the canvas from the back. When I took it down several months later, the whole painting slid right off the canvas intact, leaving the canvas completely white. I had a film of the painting which I cd mount on the window for a stained glass effect.

Dale, your explanation makes pretty good sense. The paint on the handles seems to be pretty thick and obviously brittle. When it comes off it does so in pretty big hunks. Denise showed me a big angular flat that had a split in the paint a good two inches long and was raised up about 1/8 of an inch.

George at least the handles are still there,..the last couple of years I have been using some dearsfoots fitches made by Royal langnickle and crimping the ferrule to use as wall fitch,...seems some one in their infinite wisdom designed a plastic handle with a rubber grip,...what they didn';t figure on was an old sign painter like me putting them in lacquer thinner to clean them,..they are cheap $4.95 Brushes but they `work well,.,.....till the whole damned handle melts off,....I picked one up the other day and forgot about them being plastic and the thing`was like rubber for about two strokes then fell completely off,...the brush head was still good so I put a wooden handle on it after clearing out the gooey plastic left inside the ferulle,...go figure

I would think if they're in water for too long, they would act like a wet sign and the paint would lose it's adhesion from the inside outward....sorta like wet MDO delaminating.
Just a thought... Rapid

Dale is right. All of the brushes I use in water based paint had this problem. I solved the problem by removing the paint from the handle (when the brushes are new) with lacquer thinner, so all my brushes are bare wood handles now.
Life is so good
