I am refinishing an old dining room table. I've sanded it down to bare wood, which is a beautiful light wood (https://imgur.com/a/ZWfAO9p, unsure what kind of wood this is). I really like this light wood color, so decided not to stain and used polyurethane directly on the unstained wood. Show
Oil-based polyurethane made my test piece look MUCH darker and gave it that amber hue I'd like to avoid, so I am now using water-based polyurethane (https://imgur.com/a/taue8Rz). However, I've added three coats of water-based polyurethane now and the finish is still not as thick and durable-seeming as the oil-based. This table will get heavy use so I'd like it to be easy to clean. Also, I have two cans of oil-based poly I'd like to use up. Instead of adding another few layers of water-based poly, can I add a layer or two of oil-based poly ON TOP the water-based without giving it that amber-orange look? *My posts may contain affiliate links, which means I may receive a small commission, at no cost to you, if you make a purchase through a link!

Find Out Here!Wondering if you can use an oil-based polyurethane over a water-based paint? Well, look no further because I have your answer! Oil-based polyurethane can be applied over water-based paint as long as the paint has dried fully (at least 24 hours). If the paint creates a good powder while lightly sanded then it is dry and ready for a top coat. Now that we’ve got the basics out of the way, let’s break into the details further so you can get the best polyurethane finish on your painted project. Let’s dive in!
What Happens When You Apply Oil-Based Polyurethane Over Water-Based PaintIf water-based paint has not fully dried before applying an oil-based polyurethane, then the oil will have a hard time sticking to the water. This can result in the polyurethane peeling off of the paint and not curing properly. However, if the paint has had at least 24 hours to dry and creates a good layer of powder when lightly sanded with 320-grit sandpaper, then it is fully dry. In this case, the oil-based polyurethane will have no problem adhering to the dried paint. This video does an excellent job of demonstrating how oil- and water-based products can be used over one another.  Should You Use Oil-Based Polyurethane Over Water-Based Paint?In general, oil-based polyurethane is much more durable than water-based. So if you are painting a tabletop or highly used piece of furniture or cabinets, then you will want to use oil-based polyurethane. This will provide the best protection for your newly painted piece. The only time you do not want to use oil-based polyurethane over paint is if you are using white paint. Oil-based polyurethane has a natural amber tint to it. When it is applied over white paint, it will turn the paint color yellow. Check out my article about fixing yellowing topcoats if this has already happened to your painted project. If you are using white paint, then using a water-based polyurethane such as MinWax’s Polycrylic found at Amazon will help your white paint stay looking white. Water-based polyurethanes have a little tint to them, but they are more blue-tinted than yellow-tinted. This helps the white paint retain its whiteness. Related Polyurethane Articles
