List of Clear Coats to Avoid Using Over White Paint
This list includes two popular clear coats. Usually, these brands are an easy choice among many people, but they are not suitable for your furniture.
Lacquer and Varnish
It would be best to avoid both of these brands of a clear coat when it comes to painting furniture white. Although lacquer can be used all the time, it is not suitable for white paint or super bright colors. Both lacquer and vanish will have a high tendency to turn yellow quickly.
The bottom line is that both of these brands are designed for natural wood colors and used in an old furniture style for many years. However, there us a new product produced Watco called printable lacquer paint. From personal experience, it is pretty durable and appears to retain its white color well.
You can explore this option if you haven’t begun a project and want to try this product out. It has a different feel from regular paint, but it is not exceptional.
When the white paint is involved, polyurethane is not supposed to be anywhere nearby. Polyurethane is a finish that is created to seal the wood for protection. It is specifically used to cover natural wood colors and stains. You are to use it for places where slight yellowing doesn’t impact the appearance of the piece of furniture.
Polyurethane is an excellent finish for wood furniture, but it is not suitable for white or bright-colored components. Hence, it is best to use this clear coat to finish tables and other furniture for natural or near-natural wood colors.
Best Clear Coat Sealers for White Paint
Having discussed the clear coat to avoid with white paints, we shall look at the ones you can use.
Minwax Polycrylic Protective Finish
This clear coat is considered the best choice for durable clear coat sealers over white paint. After using this product, you will appreciate its excellence. This product, when applied over the white paint, will stay clear with no sign of yellowing.
However, it can form a bubble in some parts and dry in a thick amount; this part had a tint of yellow. This issue arises if you stained the furniture and the polycrylic absorbed some of the stains before it dripped down furniture. To avoid this problem, you should apply this product in thin coats, which will help you get a crystal clear finish.
In summary, if used regularly with chalk paint, you can apply a water-based polycrylic finish, and that will take care of yellowing like usual polyurethane will do.
How to Seal White Painted Furniture using Polycrylic
The following steps will help you seal a white painted piece of furniture.
- Apply a thin coat to the dry painted surface first. You can use a foam brush or a synthetic paintbrush.
- Give it some time to dry. Afterward, lightly sand between the coats using a 220 grit sanding sponge.
- Apply the second coat and repeat steps till you have completed 3 – 5 coats.
- The last coat doesn’t need sanding. Hence, when you get to coat number 5, don’t sand it.
Chalk paints typically suggest that you finish them with finishing wax. There are several finishing waxes to select from in the market. The most common finishing wax for all kinds of wood finishing projects is Minwax paste finishing wax.
Although the Minwax has a yellow tint, when a white finishing wax is added, everything will appear pure white. Most big companies that focus solely on chalk paints and furniture painting give better wax choices for white paints. Examples of wax sealers for white painted furniture are – Annie Sloan chalk paint wax – clear, Fusion Mineral paint furniture was, and Kilz clear wax for chalk-style paint.

Oil-Based Vs. Water-Based White Painting Tips
When making a choice of white paint for furniture, avoid making use of oil-based paint. Although, oil-based paints are more robust against scuff and dents. They are prone to yellowing over a short time.
On the contrary, water-based white paints are known for maintaining white color. However, they are not as durable as oil-based ones. Hence the reason polycrylic has become so popular because it maintains the color of furniture and is durable.
The following tips will help you decide which type of paint you need to use for your furniture.
Know the sheen levels
Oil-based paints can achieve a higher sheen level when applied as a result of components of the paint. Nonetheless, the sheen becomes duller over time. On the other hand, water-based paints achieve a lower sheen finish, but they can maintain this sheen level over some time.
Usually, oil-based paints dry harder, which gives excellent resistance to wear and tear. But, as the paint dries harder, there is little flexibility within the paint. Oil-based paints will likely crack and chalky over time.
Therefore, you may want to use water-based paints if you want longer-lasting paint for your furniture.
Difference between Oil-based and Water-based Clear Coats
First, the only poly choice listed above as the best clear coat for white paint is the water-based type, Minwax Polycrylic. The justification is that it does not yellow. Since it is water-based, chances are it will remain clear. Therefore oil-based products tend to yellow after a short while.
