Guide to Buying Your Clear Coat for Cabinets
A topcoat can be used for many different projects as it can be applied alone or to an already painted surface. Stained or unfinished rougher wood is also not an issue as long your wood is properly prepared beforehand. Adding a clear coat will nourish and protect your wooden surface from any wear and tear and spills. Being in the kitchen, these cabinets are often exposed to moisture and heat regularly. An important tip to remember when using clear topcoat products is that even the best polyurethane, lacquer, wood stains, or oils may yellow with age if applied over white paint. This yellowing process is dependent on various factors like the type of wood you are painting, color and dyes already in the wood, not using the correct product, or if the wood has been exposed to moisture, to name a few.
This aged outcome is not always the case though, as some users never experience it, while others do find yellowing of their white wood over time. It is not an exact science but learning more about the techniques and products available, can assist in preventing this from happening to yours. Below are some factors to consider before sealing your painted cabinets.
Often the quality of a product and the price will go hand in hand. However, not everyone can afford top-notch products for every project. Thankfully, there are some brands that do offer quality and while still being budget-friendly.
Resistance to Scratching
Sharp objects are commonly stored in the kitchen, these can be harmful to your painted cabinets and leave marks from scratching the paint. Using a cabinet sealer that is resistant to scratching can be helpful with this concern. Another consideration is whether your cabinet sealer can withstand and protect against excessive heat and dampness that occur in the kitchen.
Type of Wood Finish
If your kitchen cupboards are unfinished or raw wood, it is beneficial to use an oil-based sealant for your cabinets. This will protect your wood and will also improve the unfinished look of your cabinets. If you would prefer to not use an oil-based option, the alternative would be to first stain your cabinets and then apply the clear finished coat on top once dry.
It is important to consider the finish you would like to get out of your clear coat as there are a few to choose from. These come in gloss, semi-gloss, and stains. High gloss finishes are easy to keep clean by just wiping them down, whereas a satin finish may be harder to properly clean. Also, remember that the texture of your cabinet sealer must be suited to the surface you are using it for. For example, one would not use a high-gloss finish on the floor as it would making the surface too smooth would be dangerous. The benefits of using a semi-gloss finish would be a more subtle shine and your cabinets would retain their easy to clean benefits.
If in doubt, a solid clear topcoat is the way to go. These have a thicker consistency which adds to their durability and water-repelling effects. You will also save on money and your time, in the long run, having applied an effective and long-lasting kitchen cabinet sealer.
Using a Clear-Coat for Kitchen Cabinets
The advantages to using a clear topcoat for painted cabinets are not only related to protecting your wood for years to come. But also from everyday use and damage from moisture, spills, and heat. The idea is to also bring out the beauty of your kitchen by accentuating one of its best features. Below, some more benefits to using a cabinet sealer have been outlined:
The most obvious benefit would be the shine or gloss factor achieved with the right product. Adding a clear topcoat to your painted cabinets will reflect any light they come into contact with. This effect brings warmth and life to your wood.
In some cases, when using paint there is a residue left behind on your surface once it has dried. When using a clear coat for cabinets, this will be easily rectified. Paints do not always cover rough spots and edges very smoothly, using a clear coat will soften those edges and create a perfect glossy finish.
Unless using paint for your kitchen that contains UV resistant elements, sun damage can be very harmful and degrade your painted cabinets. The great thing about clear coating is, when using over your painted area, it is naturally formulated to offer UV protection for your paint and cabinets.
Being prone to varying temperatures and moisture levels, sealing painted cabinets in your kitchen is key to prevent cracking and chipping of your cabinets. The problem with unvarnished or unsealed painted surfaces is that they naturally tend to chip as time goes by but applying a clear coat over the paint will prevent this from occurring.

- Remove your cabinet doors, shelves, and screws to store in a safe spot
- Wipe down your cabinets and other surfaces before starting
- Next, using 100 grit sandpaper you need to sand down your cabinet doors and drawers
- Wipe these down when done to remove any residue
- If you find gaps and cracks that need filling, one can use a simple wood putty
- Edges will need to be sanded till smooth
- This step requires an oil-based primer to be applied, this will better prepare your wood to absorb its clear coat. Allow this 24 hours to dry proceeding to the next step
- The next day, apply your clear coat with your paintbrush
- For the best results, the painting should be done top to bottom and then finished in the same direction as your wood grain
- Now, using 280-grit sandpaper sand down your surface after the first layer has been applied

Best Lacquer for Kitchen Cabinets
Lacquer is another clear coat option used to seal kitchen cabinets and other wooden surfaces. Although it doesn’t provide the same durability as a polyurethane finish, its flexibility, sheen, and impact resistance far exceed other clear coat mediums on the market. Lacquer has a few benefits including a waterproof clear coat that is also breathable and chip resistant.
They also come in different sheen levels from high gloss to matte. Opting for a lacquer clear coat can mean daily wear and tear shows up easier and your cabinets may lose their luster. This is why it is crucial to sand each layer beforehand when applying this cabinet sealer.
Benefits of Using Lacquer on Your Kitchen Cabinets
It is always helpful to know the good, the bad, and the ugly before spending valuable time and money on a product. As with other cabinet sealers, lacquer can be a versatile medium for various wood projects around the home. The points below will outline the pros and cons of using lacquer for kitchen cabinets.
Just as with your other clear coat options, lacquer also comes in a matte finish, medium finish, and high gloss finish. The matte option gives you more of a dull finish and will not add much of a shine effect. The medium finish is better at accentuating the wood grains and natural shades is more widely used for resurfacing kitchen cabinets. Lastly, the high gloss finish provides a shiny surface, but it also shows up any dust more easily.
Quick Drying Time
This is a major advantage when compared to some other top coat options, which can take almost a full week to dry properly. Using lacquer at room temperature should ensure your surface drying within at little as 15 minutes. The next step would be to sand it down slightly before applying the next coat after an hour. This process can be repeated two or three times until you obtain your desired results.
Easy to Use
Lacquer is easy to use as it does not require mixing or thinning first. It is mostly used in the form of a spray gun which provides a seamless finish. Although the consistency of lacquer means it is also easily used with a paintbrush.
Using a lacquer finish topcoat on your kitchen cabinets will outlast any of the other options available like varnish, polyurethane, stains, or shellac. It also does not age and peels like some other clear coat options. For some, this option is better than using a normal topcoat as lacquer works by penetrating deep into the wood’s actual fibers and then sealing it from the inside. Generally, it only requires two layers and those can last for up to 10 years if done correctly.
Disadvantages of Using Lacquer
Now that we understand the pros of this clear coat, we can take a look at the negatives. Each product you choose will have advantage and disadvantages which assists us in making the best possible decision. Take a look below to find out more.
Mainly due to the moisture and temperature components that cause your wood to expand and contract. This results in fine cracks in your lacquer coat causing it to become brittle. This issue is more prevalent in kitchens that are used more often than just the usual dinners. You will notice these fine cracks appearing on the doors and joints of your kitchen cabinets.
Blushing and Other Marks
Lacquer is not a sealant, what this means is If a lacquered surface is exposed to moisture, salt, water, or other chemical products, it will cause spots to form and change the color of your surface. It is also not heat resistant. Using an extra coat or two is beneficial for heat protection in the long term for your kitchen surfaces.
Blushing is a term used to describe the milky-white marks which appear on your wood if it has not been primed and buffed beforehand. You will notice them come up almost immediately once the lacquer dries. This is primarily due to any moisture or even humidity that was not dried prior to applying your topcoat. It is very important to make sure no water or moisture is present on your surface, or in your spray equipment. Everything should be clean and dry for best results.
Lacquer can be very sensitive to temperature and moisture changes in the environment. Problem areas in the kitchen would be around the sink and stove where steam and water are used often. This can cause your topcoat to break down, which will eventually affect the color and life span which can be reduced from 10 years to five. You will then need to start over, by sanding down the wood surface again and applying your lacquer.
Lacquer Does Not Keep for Long and has a limited shelf life of three to six months, so it is always best to know exactly how much you need before getting started. Using lacquer once expired will have very poor results. It is better to have too little and need to purchase extra than be sitting with a waste of expired products that cannot be used. With all the facts out of the way, if you would like to use lacquer, then take a look at the best lacquer to use for kitchen cabinets below.

How to Apply Lacquer to Your Kitchen Cabinets Using Spray Equipment
Lacquer can be applied by a paintbrush but is better applied with a spray gun. This can be harmful to breathe in as it contains noxious odors and is also highly flammable. So, it is best to wear a mask while working with lacquer or if possible, to work outdoors even. To ensure the best possible results, it is helpful to remove your cabinet doors before attempting the painting or topcoat.
- Wear a mask or set up an area outside when working with harsh chemicals
- Remove your cabinet doors, screws, and bolts before starting and put them aside
- Next, using sandpaper, buff your surface area and finish it off with a 150 grit piece if possible
- If you are working with a wood-like knotty pine or birch, use a paintbrush to apply a wood conditioner as a primer, before starting with any staining and ideally allow that to dry overnight. These specific wood materials are known to absorb your wood stain unevenly
- It is helpful to use this time to apply your stain, while the wood grain is still open from sanding
- Before spraying your wood, decide if your lacquer needs to be thinned. This will depend on your wood surface and your own preference
- Add your lacquer into the spray gun holder do not add too much to start
- Next, gently attach the air hose and turn on the compressor, once you are done applying the lacquer it will be dry in under 30 minutes
- Using 220 grit sandpaper you will sand the surface again to remove any rough bumps
- Use a cloth to wipe the area when this step is complete, and you are happy
- Generally, three coats are sufficient in sealing your cabinets, make sure the last coat is thinner and just enough to finely spray over your last sanded layer
