Combining Water-Based and Oil-Based Products

Water and oil don’t mix, but water-based and oil-based finishing products can be combined as long as the previous coat is dry. Water dries considerably faster than oil so you can apply an oil-based finishing product over a water-based product within a couple of hours. On the other hand, you should allow at least overnight, and often several days, before applying a water-based product over an oil-based product or you may get wrinkling or poor bonding.
