Varnish is a type of wood finish that is typically applied to outdoor furniture or trim. It helps protect the wood from weathering and fading. However, varnish can also yellow over time or become cracked and peeling. If you want to refresh your varnished wood, you can paint over it.

Here are a few things to keep in mind when painting over varnish:

– Choose the right type of paint. You will need to use an oil-based paint if you are painting over varnish. Water-based paint will not adhere properly to the varnish surface.
– Prepare the surface. Make sure the varnished surface is clean and free of any dirt, dust, or debris before you begin painting. You may need to sand down the surface to create a rough texture that will help the paint adhere better.
– Apply primer. Once the surface is prepared, apply a coat of primer before painting. This will help the paint adhere better and prevent peeling or chipping in the future.
– Allow ample drying time. After applying primer and paint, be sure to allow adequate drying time before using or touching the painted surface.

What is Varnish Wood?

Varnish is a clear, hard, protective finish or film that is primarily used in woodworking. It can provide a good level of protection against rough use and wear and tear.

There are two types of varnish:
-Oil-based varnish- This type of varnish is made with natural oils and resins. It works well as a primer under paint and gives surfaces a nice sheen. It can take up to 24 hours to dry fully.
-Water-based varnish- Made with synthetic resins, this type of varnish dries quickly (in about 2 hours) and has little to no odor. Water-based varnish also levels out nicely, so it’s a good choice for projects that require a smooth finish.

Preparing the Surface

If you want to paint over varnish wood, you need to take the time to properly prepare the surface. Otherwise, the paint will not adhere correctly and will eventually peel away.

The first step is to sand the surface of the wood. This will create a rough surface that the paint can grip onto. Be sure to sand along the grain of the wood and not against it.

Once you have sanded the surface, you need to wipe it down with a damp cloth. This will remove any dust or debris that was created during the sanding process.

After you have prepared the surface, you are ready to start painting. Be sure to use a primer designed for use on varnish wood. This will help the paint to adhere better and will also prevent bleed-through from occurring.

Applying the Paint

It’s best to wait until the varnish is completely dry before applying the paint. This will ensure that the paint adheres properly to the surface. Once the paint is applied, it will create a barrier between the varnish and the wood, preventing the varnish from peeling or flaking off.

Finishing Up

Whether you’re painting trim or walls, you need to take the proper steps to ensure that your paint job is successful. This is especially true when painting over varnish wood. Varnish is a type of finish that’s applied to wood to protect it from damage and give it a shiny, lustrous appearance. However, varnish can also make painting more difficult. Here’s what you need to know about painting over varnish wood.

The first thing you need to do is determine whether the varnish is in good condition or not. If the varnish is cracked, peeling, or otherwise in bad shape, it’s best to remove it before painting. This can be done with a paint stripper or sandpaper. Once the varnish is removed, you’ll need to clean the surface of the wood before painting.

If the varnish is still in good condition, you can paint over it without any problems. Just make sure that you use a primer designed for use on varnished surfaces. This will help the paint adhere properly and create a smooth finished surface.


In general, you can paint over varnish wood. However, there are a few things you need to do to prepare the surface for painting. First, sand the surface of the wood to rough it up and create a better surface for the paint to adhere to. You will also need to use a primer designed for painting over varnish before you paint. Follow these steps and you will be able to successfully paint over varnish wood.
