I have several rental properties that seem like they’re always in need of repainting. Instead of throwing out leftover paint, only having to buy more later, I put it to use. I take multiple cans of interior latex, partially used paint and primer, any sheen, any color, and mix them all together. It doesn’t matter how much junk or debris is in the paint. Just pour it all in. I use a power mixer to blend them, and then dump all of the mixture into a bigger container. I did twenty gallons of paint once using a big round plastic tub. After all the assorted paints are in the vat are mixed, it usually ends up an off-white or antique white. The sheen is usually an eggshell to satin. If the color is too loud, I tone it down by adding a can of white paint. Now, I pour the paint into 5-gallon buckets with strainer bags inside. Lift out the strainer bags to remove any debris and pop on a lid to keep the paint fresh. This is a great way to use up leftovers when you do a lot of painting. — Tom Dvorak
