Should You Paint Over Polyurethane

Hey Friends! Answering another one of the questions that we get frequently. Is it okay to paint over polyurethane? This information will work for water based products & more specifically Chalk Type Paints. These paints are formulated to have a strong adhesion. While we may all relate to the allure of quick and easy. When painting anything it is best to remember that your paint is only as good as what it is sticking to. One of the biggest selling points with chalk type furniture paint is the "no prep needed" message claimed by most every brand. The truth is that even the best paint products must have a secure base to stick to. Never underestimate this information, unless you love peeling paint and redoing the work. Painting is my jam, but I don't want to do a job twice!

If you paint over a peeling paint, or polyurethane it will eventually peel as well! Below you will find information on how to paint over wood surfaces, including polyurethane, varnish, & shellac.

The Good

 These would be pieces that have been in a house, or somewhere with climate control. Pieces that have NOT been painted before. No major damage, gouges, or deep scratches. 

The Bad

These pieces were likely stored in a garage. Grandma loved it dad hated it but kept it. Some missing stain and finish. Surface scratches in the polyurethane and in the wood. Painting over this polyurethane with scratches may show the dents. We are even more concerned that if the finish is peeling it may continue even under the paint.

The Ugly

Peeling lacquer, shellac, or paint. YOU MUST NOT PAINT OVER POLYURETHANE like this. If you plan on making these pieces over you will have to use a little elbow grease & you may need to bring in some help. See how there are several layers of peeling? Once that old finish starts to peel, there is no promise that it will stop. There are several ways of removing the old finish. I will share the one I used here with you and hope it helps in your adventures.

I hope these details make sense to you. Always follow the manufacturers instructions on the products you choose. It is important to follow all safety guidelines. Use safety glasses, respirator masks, and gloves. We recommend sticking to non toxic products whenever possible!
