The problem is I can't get all of the painting done in one evening. I have a total of 10 shelves to prime and paint for the closet. Not to mention the 9 shelving units (I call them QB's), a bookshelf, and my cedar chest. All require priming and painting. It's bad enough I have to clean the paintbrushes. But I hate trying to clean a paint roller so I can reuse it the next night. It never works. There is always some paint left on the roller to dry. Then it's crusty and doesn't leave a nice, neat surface.
After a late night of painting, I was extremely tired and had more painting to do the next evening so I decided to cheat on the clean-up. I thought I'd try this and if it didn't work, I'd just use another paint roller and get a new cup. It would cost me a dollar or two at the most.
Tip 1: Wrap the paint roller in aluminum foil before removing from the handle. Pull the roller gently off making sure the aluminum foil doesn't slip. Once removed tuck the aluminum foil into the paint roller on both ends. It keeps the roller wet and you don't have to waste another on the next day. To place the roller back onto the handle, simply untuck one end of the aluminum foil, push the roller onto the handle from the other end and remove the aluminum foil. I make sure to do this over the trash can to avoid paint drips on my floor. I'm on day three of the same roller and it's like I just pulled it out of the package and started using it.
Tip 2: When using a small paint pan for edging (I use a plastic cup), cover with cellophane and secure with a rubber band. The paint does not dry out or get a nasty paint booger on top. For the larger paint pan, purchase a liner. They cost less than a $1 and are well worth it.
