What Top Coat Is Best for Painted Cabinets?
Besides personal preference, there are specific considerations one must take into account before deciding on a top coat. The function and placing of the cabinet are essential considerations and the frequency of use and the occupants of your household. High traffic areas with children, for example, would need a surface that you can easily clean off fingerprints and smudges.
Other considerations are the aesthetic choices in terms of your decor and design and your cabinet’s material. Other factors to consider when choosing a top coat are:
- Daily use. If your cabinet is in a kitchen, for instance, one should factor in wear and tear. Oil-based polyurethane is an excellent option for durability and wear and tear resistance.
- Exposure to humidity and UV rays. If your cabinets are in a sunny room or exposed to high humidity areas such as bathrooms, one would need a top coat that protects from UV damage or expands and contracts with temperature changes such as water-based polyurethane with specialized oils.
- Your cabinet materials base also dictates which top coat to use. Some clear coats add a rich amber tone to cabinet surfaces, ideal for a wood finish. However, light-colored surfaces or white surfaces would benefit from clear drying type coats.
- Ease of application. There are a variety of top coats with varying degrees of difficulty of application and drying times. For jobs on the go, you may opt for a cloth application top coat with minimal fuss.
- Cleaning. Some top coats only require soap and water for cleaning, while other surfaces require mineral spirits. In a high traffic area with exposure to marks and spills, a water-based cleaning system is more manageable and eliminates high odor cleaning substances.

What Is the Best Sheen for Top Coats on Cabinets?
As a rule of thumb, the higher sheen finishes are more durable because they use a higher concentration of binders. However, the higher the sheen, the greater the daily smudges and dirt will tend to be highlighted, so they need more frequent cleaning. The high gloss may lend itself to a display of sticky little fingerprints for a family with small children more quickly than a more matte finish.
There are various sheen levels available, ranging from matt to and satin to semi-gloss gloss and full gloss. The primary difference in these finishes is the amount of light that they reflect off your surfaces. Lower sheen is less likely to show up scratches and dirt.
Matte and Satin Sheen
Matte finishes can hide imperfections and dirt but can appear dull. With virtually no light reflection, matte surfaces may appear relatively ‘flat’ in your kitchen or bathroom. The satin finish is quite popular and offers a medium to low sheen/luster, and still hides minor scratches or dirt to the naked eye. It is still clear enough to show off color finishes and or wood grain without dulling the surface.
Semi-Gloss and High Gloss Sheen
Semi-gloss is next up in the luster scale and correspondingly increases in upkeep and cleaning. The high light reflection, smudges, and marks in higher traffic areas will need regular cleaning to look neat, which is not ideal for children’s sticky fingers.
Full gloss is beautiful with full light reflection and can make the underlying surfaces come to light beautifully. Full gloss emphasizes paint finishes colors and highlights their effect. However, these finishes are high maintenance in high traffic areas like kitchens and dining rooms and benefit cabinets in quieter and less often used areas.
Why Do You Need a Top Coat for Your Cabinet?
There are many benefits to having a top coat on your cabinets beyond the apparent protection it affords your cabinet surfaces. Top coats can prolong the life of wood and painted surfaces and provide an aesthetic appeal through your choice of sheen.
- Makes surfaces easier to clean. Top coats can provide a glossy surface that is easier to wipe and clean than wood or paint finished surfaces.
- Water resistance. Polyurethane surfaces provide excellent water resistance for high moisture areas such as bathrooms and kitchens. Top coats protect the surface underneath from stains and water damage.
- Helps avoid paint degradation. Cabinets in high light areas can discolor over time due to the effects of UV rays. Top coats offer UV resistance and prolong the life of the surface beneath them.
- It helps prevent paint damage. Temperature changes cause the paint to shrink and expand, causing the paint to chip or flake over time. Top coats protect from temperature changes and increase the lifespan of your cabinet surface.
- Modern touches. High gloss furnishings such as brightly painted cabinets can liven up a drab room and give a modern flair to your home.
- Adds interest without having to introduce color. Placing a top coat adds to light reflection without resorting to color to liven a drab space. High sheen top coats can highlight your paint effects beautifully and make your cabinets a feature.
What Is a Polyurethane Top Coat?
A polyurethane (PU) product is a coating system created from the chemical reaction between a polyol resin and a polyisocyanate curing agent. Ploys are a kind of enhanced varnish that uses microscopic molecule chains that bind tightly with each other as it dries. The resulting finish is more resistant than traditional varnish to factors such as:
Polyurethanes come in two different varieties, namely, water-based and oil-based polyurethanes (polys.) Both polys act as armor for your cabinets and protect the underlying surface from damage. Both polys provide a ‘sacrificial layer’ which takes scratches and wear marks instead of the underlying surface.
Water-based polys have acquired a reputation for being less durable than oil-based polys, but that assumption stems from the early days of water-based poly technology. Water-based polyurethanes now have the advantage of high durability and, when correctly applied, will last equally long if taken care of properly.
Should You Use Water-Based or Oil-Based Poly?
Both water and oil-based poly are excellent alternatives to finishing and protecting your cabinets. The main differences are in function suitability and the material and positioning of your chosen piece of furniture. The vital differences between the two rest in the following factors:
Oil-based poly dries to a warm amber hue, whereas water-based poly dries from cloudy to a clear, transparent finish. Oil-based polys also tend to darken over time, while water-based polys don’t discolor over time. Users should take care that they don’t use an oil-based poly on white or light-colored cabinets as they will yellow over time.
Oil-based poly takes a substantially longer time to dry and cure and may need 24 hours between coats. Water poly is fast drying, and you can apply several coats a day. On average oil-based poly takes two to three times as long to dry as water-based poly. Water-based poly allows multiple layers, while oil-based poly tends to be prone to ‘sheeting’ scratching and denting when applied in multiple layers.
Oil-based poly has a pungent smell and has a strong chemical odor as well as hazardous fumes. These polys require the use of a respirator, and one should never directly inhale the fumes in the application. Oil ploy contains many Volatile Organic Compounds (VOCs), making it hazardous for human health, while water-based is user friendly. Water polys are safe to apply without a respirator and don’t create a chemical smell, making them a breeze to use.
Thickness and Hardness
Oil-based poly is thicker than water poly, but it is softer and more susceptible to dings and dents. Water poly is thinner but has a harder surface finish. Thus water-based poly requires several coats, while two coats of oil poly will suffice on your cabinet surfaces. Some say that oil polys have a smoother finish, but water-based polys are as smooth to the touch when applied correctly and in sufficient layers.
Water-based poly is a more expensive purchase for quality brands with good durability. This price is because you need more layers of water poly. After all, these polys have 30-35% solids vs. the 45-50% solids of an oil-based poly. When you choose a multiple-layer effect for high traffic areas, your costs increase with water poly due to the extra quantity needed.
Water-Based Oil-Modified Polyurethane
A great alternative to water or oil polys is the best of both worlds, the water-based oil-modified polyurethane. This poly appears cloudy in the can but dries quickly to an amber film like the oil-based poly. It has the same VOC levels as water-based polys and offers the durability of oil polys and the easy cleanup of water-based poly finishes.
The combo poly can be applied with a foam roller or rag and synthetic brushes, much like water polys and are low odor. This poly is also versatile and is compatible with all woods giving users greater flexibility. Oil-modified polys have the added benefit of using both oil and water-based finishes of your cabinets.
Whether you seek to increase your cabinets’ lifespan or wish to make them a stand out feature in your home, there are plenty of options available. Ensure that you get the right coating to suit both the cabinet materials and the environment you intend to use them in. Polyurethanes make a great choice and combine practicality with a wide variety of glossy sheens to enhance your cabinet’s appeal.
