How To Paint Over Varnished Wood

Whether you are a flea market shopper or the one who loves shopping for varnished wood furniture, it is common to wonder if you can paint over varnished wood to give a fresh look. Painting over varnished wood is time-consuming and demands proper prep work and the right tools. Since varnished surfaces are smooth and non-porous, paint doesn’t easily adhere to them.

That’s why sanding, priming, and picking the right paint are key steps for a strong, lasting finish. With the right surface prep, you can achieve a stunning makeover.

Can You Paint Over Varnished Wood?

Yes, you can paint over varnished wood. The key is proper preparation: clean the surface, lightly sand to roughen the varnish, then apply a bonding primer. This helps the paint stick properly and ensures a durable, long-lasting result.

How to Paint Varnished Wood?

Follow these essential steps to achieve a smooth, durable painted finish over your varnished wood surfaces.

Step 1: Clean the Wood Surface Properly

Before you start the painting process, clean the wooden door or surface properly. This is because dust, dirt, and debris can stop the paint from sticking well. Wipe the surface with a damp cloth to remove any buildup. You can also use a cleaning agent like mild detergent mixed with water for a deeper clean. This step removes any dust, grease, or grime that might interfere with paint adhesion.

Step 2: Apply a Coat of Primer Evenly

Choose the best quality primer to give a glossy look to the varnished wood surface. For optimal results, select a high-quality primer specifically made for varnished surfaces and let it dry for a minimum of 24 hours. Do follow the manufacturer's instructions before applying. This way, you get a uniform finish.

If you're planning to use oil-based paint, go with an oil-based primer. For water-based or latex paints, a latex primer is the right choice. This step is essential to achieve a smooth, long-lasting finish.

Step 3: Apply the First Coat of Paint 

Let the primer dry completely before applying two coats of paint. Use a paint roller or paint brushes for better results. Make sure to stir the paint well before you begin. Apply the first coat evenly, keeping an eye out for any drips or streaks. 

Step 4: Lightly Sand for a Smooth Finish

If you see visible brush marks after priming, you can lightly sand the surface to smooth it out. Use fine-grit sandpaper for best results. Once the sanding is done, wipe away any dust with a clean, damp cloth. Proper preparation like this helps your final coat of paint go on smoothly and look its best.

Step 5: Apply the Second Coat of Paint

Add a second coat of paint and look for any missed spots or thin areas. This helps improve colour richness and coverage, giving your wood a neat, finished appearance.

Step 6: Lightly Sand after Final Coat

For smooth results, lightly sand the final thin coat with very fine sandpaper (320-grit) once fully dried. This optional step creates a professional, furniture-quality finish. Wipe away any dust with a soft, clean cloth.

Key Takeaways

With the right preparation, painting over varnished wood is completely doable. By cleaning, light sanding, priming, and applying two coats of paint, you can refresh your furniture or doors with a whole new look.
