We're in the middle of painting the entire inside of a two-bedroom house right now, and thought we would share one of our favorite painting tricks. If you're using latex paint, brushes and rollers can be frozen overnight, saving you the arduous task of cleaning them until you're done with the project.
Simply put the brush or roller into a plastic bag and stick it in the freezer. When you're ready to start painting again, all you have to do is take it out and let it thaw. We've successfully re-frozen and re-thawed the same brush several times, the trick is not to forget about it when it's thawing - too long out of the freezer and the paint on it will start to dry.
