Q: Is there a way to rejuvenate old latex paint?
A: You might be able to reclaim the old paint, depending on its current condition. First, open the container and remove any obvious skins, or hard pieces, but leave soft lumps in place. Do not pour off any of the liquid. This should be kept as part of the paint. The container should then be mixed thoroughly, preferable at a paint store. Or, use a paint stir-stick and stir each container thoroughly for 5 to 10 minutes. After the mixing, if the paint is free of specks smooth and uniform (not thin or runny), it should be okay. Check the paint by applying it to scrap material, and look for a uniform sheen and color.
