Precautions Before Painting Over Varnish with Chalk Paint

Precautions Before Painting Over Varnish with Chalk Paint

If you’re planning to use chalk paint on a varnished surface, there are some important precautions to take before painting. These steps will ensure that the paint adheres well and the finished result is smooth and long-lasting.

The first step is to clean the surface thoroughly. Use a mild detergent and water solution to remove dirt, dust, and grease that can affect the paint’s adhesion. After cleaning the surface, rinse it with clean water and let it dry.

Next, it’s important to test a small area of the surface with chalk paint. This will help you determine whether the paint adheres well to the varnish and whether the finished result is satisfactory. 

If the paint does not adhere well, you may need to take additional precautions or consider using a different type of paint.

If the varnish has a glossy finish or is peeling, you may need to sand the surface lightly with fine-grit sandpaper to create a rough surface for better adhesion. This step is not always necessary, but it can be helpful in some cases.

If the varnish is oil-based or has a dark color, it is recommended to apply a primer before painting with chalk paint. This will help prevent bleed-through and enhance adhesion. Choose a primer that is compatible with both the varnish and the chalk paint for the best results.

Taking these precautions allows you to paint straight over varnish with chalk paint and achieve a beautiful, long-lasting finish. Not only is this a cost-effective way to update your furniture or decor, but the matte and vintage look of chalk paint can also complement the glossy finish of varnish for a unique and stylish result.

However, it’s important to properly prepare the surface to ensure the chalk paint adheres and looks its best. Here are the steps to follow:



Before starting to paint, assemble all necessary supplies, including chalk paint, brushes, and a drop cloth. Next, clean the surface to remove any dirt, dust, or grease that may have accumulated. Clean the surface with mild detergent and water and let it dry completely before painting.



Use thin, even coats to avoid drips or clumps when applying the chalk paint. Depending on the size of the surface, use a brush or roller to apply the paint. Make sure each coat dries completely before applying the next. 

It’s important to note that applying too much paint at once can result in a longer drying time and a less smooth finish.



The number of coats of chalk paint needed will depend on the varnish’s color and the paint’s desired color. In most cases, two to three coats of chalk paint will provide adequate coverage. 

Be sure to wait for each coat to dry before applying the next one to ensure the best results.


After applying the final coat of chalk paint, allow it to dry for at least 24 hours before using or handling the painted surface. This will ensure that the paint fully adheres to the varnish and creates a durable finish.

Sealing Chalk Paint Over Varnish

Explanation of the Importance of Sealing Chalk Paint

Sealing chalk paint over varnish is an important step in the painting process as it helps to protect the painted surface from scratches, stains, and water damage. Chalk paint is porous, and without a sealer, it can easily absorb liquids, leading to stains and discoloration. 

Additionally, chalk paint can also scratch or wear off over time if not sealed, making the surface vulnerable to further damage.

Types of Sealers 

Two main types of sealers can be used to seal chalk paint over varnish- wax and polyurethane. Wax gives a soft, matte finish and is easy to apply, making it a popular choice among DIYers.

However, wax requires regular reapplication and may not offer as much protection as polyurethane. 

Conversely, polyurethane provides a harder, more durable finish that can withstand more wear and tear. It is also available in different finishes, including matte, satin, and glossy.


Apply the sealer using a clean brush or cloth in thin, even coats. Allow each coat to dry completely before applying the next one.

When applying a sealer, it is important to use a clean brush or cloth and apply the sealer in thin, even coats. The first coat should be allowed to dry completely before applying additional coats. 

The number of coats needed will depend on the type of sealer used and the desired level of protection. To achieve a uniform finish, avoiding overworking the sealer or applying too much pressure is also important.


Make sure the sealer cures for 24 hours before you use it.

Before using the painted surface, let the sealer cure for at least 24 hours after applying the final coat. This will ensure that the sealer has fully dried and hardened, providing maximum protection to the painted surface. 

if the painted surface is used before the sealer has fully cured, it may be susceptible to scratches, stains, or other damage.

Can you chalk paint over varnish without sanding?

You can chalk paint over varnish without sanding, but it’s important to clean the surface thoroughly and apply a sealing coat to protect the paint. While sanding isn’t necessary, it can still be done for improved adhesion and a smoother surface.

How come my chalk paint is coming off of my varnish?

There could be several reasons your chalk paint is coming off your varnish. It may be due to inadequate surface preparation, such as not cleaning or sanding the surface properly before painting. 

Another possible reason could be using low-quality or incompatible paint or not applying a sealer over the chalk paint. Before applying the next coat of paint, make sure the previous one has dried completely.

Lastly, proper surface preparation, quality materials, and applying a sealer can help prevent the chalk paint from coming off of the varnish.

After chalk painting over varnish, do you need to seal it?

It is recommended to seal chalk paint after painting over varnish. Sealing the chalk paint will protect it from wear and tear, moisture, and fading. As a bonus, it’ll make cleaning and maintenance easier.

You can use a wax or polyurethane sealer to seal the chalk paint, depending on your preference and the level of durability you require. Let each coat dry completely before applying the next sealer. Allow the final coat to cure for at least 24 hours before using the painted surface.

Achieve a Smooth and Durable Finish with Chalk Paint Over Varnish

Finally, painting over varnish with chalk paint is possible but requires some precautions and steps to ensure good adhesion and long-lasting results. 

Cleaning the surface, testing a small area, and priming are important steps that should not be overlooked. Sanding may also be necessary for better adhesion, especially if the varnish is glossy or peeling. 

Applying chalk paint in thin, even coats and allowing each coat to dry completely is crucial for a smooth finish. Finally, sealing the chalk paint with wax or polyurethane is necessary to protect it from wear and tear. 

Following these steps, you can achieve a beautiful and durable finish with chalk paint over varnish.
