How to Paint Over Varnished Wood

Painting over varnished wood can be a quick and easy way to give new life to an old piece of furniture. You don’t need to sand the wood down first, just make sure you use a good quality primer and paint. With a little bit of prep work, you can have a beautiful new piece of furniture in no time!

Step One: Prepare the Surface

Sand the surface with a 120-grit sandpaper to rough up the varnish. This will help the paint to stick better. If you’re working with a large area, you can use an electric sander to make the job go faster. Be sure to wear a dust mask while you work and to vacuum up the sanding dust afterwards.

Next, wipe down the surface with a damp cloth to remove any remaining dust. Allow the surface to dry completely before proceeding to the next step.

Step Two: Apply a Primer

Once you have sanded the wood, you will need to apply a primer before painting. This will help the paint adhere to the surface and provide a uniform base for the paint to cling to. When choosing a primer, make sure it is appropriate for use on varnished wood. Some primers are specifically designed for this purpose, while others can be used on a variety of surfaces.

If you are unsure which primer to choose, ask a staff member at your local hardware store or painting supply store. They will be able to recommend a product that will work well with your specific project.

Once you have chosen a primer, follow the instructions on the label regarding how to mix and apply it. In general, you will want to apply the primer with a brush or roller, using long, smooth strokes. Allow the primer to dry completely before moving on to the next step.

Step Three: Paint the Surface

Now that your wood is clean and dry, you’re ready to start painting. If you’re painting over varnished wood, you don’t need to sand the surface first. Just make sure to use a paint primer designed for glossy surfaces. We recommend Zinsser Bulls Eye 1-2-3 Primer.

Once your primer is dry, you can start painting with your chosen paint color. We recommend using a satin or semi-gloss paint for a varnished surface. These paints will help to protect the varnish and make it easier to clean in the future.


If you want to paint over varnished wood without sanding, you can do so with the right kind of paint. There are two main types of paint that can be used on varnished wood: oil-based paint and latex paint. Oil-based paint will adhere to varnished wood without the need for a primer, but it can be difficult to work with and cleanup can be messy. Latex paint will also adhere to varnished wood, but it will require the use of a primer. Both oil-based and latex paints will give you a smooth, professional finish if applied correctly.
