I was just about to do some touchup work in a room when I discovered upon opening the can that the remaining paint had thickened into a much thicker consistency. I think the lid may not have been on correctly.
Can I use it as is for touch ups? Or would it be best to apply some kind of thinner? Do I have to go out and buy paint thinner, or is there something else I could use that would spare me the trip to the store?
Its latex paint, about a year old. From Benjamin Moore.
