Giving old furniture, cabinets, or wood trim a fresh coat of paint can totally change the look of your space. But many homeowners pause and ask, can you paint over polyurethane without the paint peeling or chipping later? It’s a smart question because polyurethane has a slick surface that doesn’t easily grab onto paint.
If you’re looking to update wood surfaces without fully stripping them, you’re in the right place. In this guide, we’ll walk you through everything you need to know about painting over polyurethane, the right tools, best paint types, and when it’s worth calling in a pro for help.

What Is Polyurethane?
Polyurethane is a clear, protective finish often used to seal wood surfaces. It creates a strong, durable coating that helps protect against scratches, moisture, and wear. Many homeowners use it on furniture, wood floors, doors, and trim to keep the wood looking new for years.
You’ll often find painting polyurethane surfaces challenging because of their slick, glossy texture. This finish is designed to resist damage which also means it resists paint. Whether it’s a shiny or matte poly finish, paint won’t stick properly unless the surface is prepped the right way.
Before you apply any paint and polyurethane, prepping the surface is key. That means cleaning, sanding, and using a quality bonding primer. Skipping this step can lead to peeling or uneven results, so a little prep work goes a long way in making sure your paint job lasts.
What Types Of Paint Can You Use Over Polyurethane
Choosing the right paint makes all the difference when painting over urethane finishes. Not all paints will bond well, but with the proper prep and primer, several types can work beautifully.
- Oil-based paint: A strong choice for durability. Works well over polyurethane when the surface is sanded and primed.
- Latex paint over polyurethane: Can be used, but must be paired with a high-quality bonding primer to avoid peeling.
- Chalk paint: Great for furniture makeovers. It sticks well with light sanding and primer, offering a smooth matte finish.
- Enamel paint: Ideal for trim and cabinetry, providing a tough, cleanable surface.
- Avoid cheap, low-adhesion paints: These often won’t bond well and may chip or peel easily.
When you paint wood polyurethane surfaces, always use a bonding primer designed to grip slick finishes. Skipping this step can lead to a finish that doesn’t last, no matter what paint you choose.
