After switching to acrylic craft paints many years ago from using Polly S and Poly Scale acrylics, one recurring problem is that, over time, the paint tends towards lumpiness. Even with vigorous shaking, the craft paints I use (Delta Ceramcoat primarily) can still maintain coarse pigment grains and outright lumpiness. Sometimes, the paint is very gooey and thick straight from the bottle. The problem could be magnified in old bottles of paint but even a new bottle can contain lumps and grainy pigments.
On a recent browse on Amazon.com, I came across a paint mixer from Badger that looked quite interesting. At not much more than $10, I figured, why not give it a try?
As in all Amazon.com purchases, I had the little device in my hands in no time at all.
Quick to give it a test, I grabbed a lumpy bottle of white paint and set to work. From the photo below, I stopped the motor and pulled the rotor out of the bottle. See all of the gunk that has accumulated on the rotor and stem? Yuck.
After cleaning the stem and rotor of the gunk, the mixer was placed back into the bottle for a second round of mixing. This time, very little residue was left on the mixer and the paint in the bottle looked smooth.
A couple of cautions: only turn the mixer on after it has been submerged into the paint and always turn it off before pulling it from the paint jar.
Before using this mixer, I thought vigorous bottle shaking was sufficient to break up the lumpy pigments and provide a smooth paint mixture. After using the Badger mixer, that thinking was wrong. How did I manage without this device?
