Handy Tips, Advices, Ideas & Warnings
When painting, protect your hands and face with moisturizer. Cleanup will be easier and the moisturizer will prevent paint from seeping into the pores.
Before starting to paint with enamel paint, lightly coat your hands and underneath your fingernails with any name brand hand cleaner. After the painting is finished, your hands will be easy to clean.
Line your paint tray with aluminum foil. When it’s time to clean up, just roll up the foil and throw away.
To stop paint from dripping, punch a few holes in the rim of the paint can. When the brush is wiped against the edge, the paint flows back into the can. The lid covers the holes so the paint won’t dry out.
To remove lumps from paint: Cut a piece of screen to fit the inside of the paint can. Set it on top of the paint and let it float down to the bottom of the can. It will take all the lumps with it, trapping them at the bottom of the can.
