The right wood finish can bring out the natural beauty of the wood, protect it from damage, and make it last longer. So, our paint experts detail the types of wood finishes, plus a quick buying guide to help you pick the best one for your project.
Different Types of Finishes for Wood
There are two primary classifications of wood finishes for wood—surface and penetrating finishes.
Penetrating Finishes
Penetrating wood finishes are transparent wood stains or sealers specifically designed to protect and beautify the natural look of wood.
Cedar Oil
Cedar Oil, also known as cedarwood oil finishes, is an amber-colored essential oil that is obtained from various types of conifers and cypress trees.
Danish Oil
Danish Oil finishes are a wood-finishing product that has been around for centuries and is still a popular choice for modern woodworkers and outdoor furniture.
Linseed Oil
Linseed Oil finishes are a natural, multi-functional product with ideal uses. It comes from soaking flaxseed until the boiled linseed oil is released.
Tung Oil
Tung oil is a type of drying oil derived from the seed of the tung tree and has an attractive, honey-colored hue.

Surface Finishes
A wood surface finish does more than just protect the wood from wear and tear. It can also bring out the natural beauty of the wood grain and highlight its texture.
Dye
Wood dyes as a wooden surface finisher are becoming increasingly popular due to their versatility and range of colors available.
French Polish
French Polish is an oil-based wood finish that is perfect for furniture pieces such as cabinetry, chests, and other high-quality wooden furniture items.
Lacquer
For applications requiring a sleek, glossy look, lacquer is the ideal choice. Available in colors ranging from bright shades to darker tones.
Polyurethane
Polyurethane is one of the popular types of wood finishes as it offers durable protection and a vibrant aesthetic. You can choose to use water-based or oil-based polyurethane, depending on your project.
Paint
Paint is a standard finish used on wooden surfaces to create an aesthetically pleasing look.
Shellac
Shellac is an ideal wood furniture finisher as it is highly durable, can easily be applied with a brush or rag, and dries quickly. There’s also a dewaxed shellac, where you can use it to prevent water absorption.
Stain
Different wood stains are ideal for different applications and should be carefully chosen based on their intended use:
- Water-Based Stain: These stains are easy to apply with the required application tool, such as a brush or foam applicator, and come in a variety of colors.
- Oil-Based Stain: Coming in a variety of colors and shades, applying an oil-based stain starts with a basic unified coat over the surface.
- Gel-Based Stain: Gel-based Stain is a great solution when looking to finish any surface of wood furniture.
Varnish
It is a wood finisher known for its long-lasting durability and lustrous shine.
Water-Based Finish
Water-based wood finishes are ideal for increasing longevity and wood finish durability.
Wax
Wax is a popular choice for those seeking to finish a wooden surface. We like how wax finishes provide deep, luscious color tones that promote the natural appearance of the wood being worked on.
- Carnauba Wax: Carnauba wax finishes are a type of wax that is derived from the leaves of the carnauba palm tree.
- Beeswax: Beeswax is a type of wax that is secreted by bees.
- Mineral Oil Wax: It is a type of wax that is derived from petroleum[1]
Wood Preserve
Wood preservatives can penetrate deep into the wood and protect against rot, fungus, and termite damage.
Choosing a Wood Finish: A Buying Guide
Color and Look
Color helps create a feeling or atmosphere in a space. A light color may help an area feel more open and bright, while darker colors might create a sense of warmth and coziness.
Type of Project
Different types of finishes, varnishes, and stains work better for different materials and objectives.
Humidity and Sunlight Exposure
Certain wood finishes are more susceptible to damage at certain levels of humidity.
Your Skill Level + Ease of Application
Consider factors like the coverage area, the type of surface you are covering, environmental conditions, drying times, and the required number of coats.
Tool Requirements
Decide if you’d like to use a water-based or oil-based finish. Make sure to use the proper application tools.
Safety and Sustainability
It is important to look for finishes that use non-toxic ingredients, such as natural oils or waxes.
Durability
Oil-based products tend to break down over time; however, they can provide longer-lasting protection against mildew and UV rays when applied correctly.
Drying Time & Process
Many products claim to dry quickly, but this does not necessarily mean that they will be dry within a few hours; some could require days of curing before the full effect is realized.
Cost
Finishes can range from relatively inexpensive options like wax and shellac to higher-priced selections such as lacquer, urethane, and varnish.
Process Involved in Wood Finishing
There are two steps involved in doing your wood finishing:
Step #1: Get Rid of the Old Finish
Sanding
This process helps smooth and shape the surface, helping to create a more professional-looking finish.
Using Chemicals
Chemical additives can be mixed with Danish or Tung oil to create an even smoother, more professional-looking finish on wood surfaces.
Using Solvents
Utilizing solvents can be an efficient way to achieve smooth, high-gloss wood finishes without leaving brush marks or streaks.
Step #2: Apply the New Wood Finish
Prepare the Surface by Sanding
Sanding smooths out any bumps or unevenness in the surface, resulting in a more even coat of finish.
Apply the Stain
When applying the stain, ensure that you have a suitable brush or cloth; then spread an even amount across the surface.
Apply the New Finish
Apply a sealer coat to protect the wood from any discoloration that could result from applying the final finish.
Wood Stain vs Wood Finish
Wood Stain is designed to color natural grain and textures in the wood, adding depth and character. Wood Finish is a protective layer that coats the surface of the wood.
Both are applied either with a brush or rag, but the wood finish takes longer to dry due to its thicker texture.
What is a Wood Stain?
Wood stain is a transparent, colored liquid that penetrates the grain of the wood.
| Consistency | Drying Time | Purpose | Application Time | Results | |
| Wood Stain | Liquid | 24-72 hrs. | Seals wood pores | 4-6 hrs | Rich color |
| Wood Finish | Thin | 8-24 hrs. | Prevents cracking | 12hrs + | Natural appearance |
How to Distinguish the Type of Finish
Finishes are designed with specific characteristics in mind. Take a look at the table below:
| Testing Method Used | Type of Finish | Reaction/s |
| Acetone | Shellac | The swab becomes tacky |
| Polyurethane | The swab becomes beady | |
| Lacquer | Finish dissolves | |
| Denatured Alcohol | Varnish | Finish dissolves slowly |
| Shellac | Finish dissolves quickly | |
| Lacquer Thinner | Lacquer, Shellac, and water-based finishes | Finish dissolves |
| Urethane, Alkyd, or Phenolic varnish | No pronounced effect | |
| Oil | Shellac, Lacquer, Varnish, or Polyurethane | Oil beads on the surface |
| Xylene | Water-based finish | Removes the coating |
| Oil-based finish | Doesn’t remove the coating | |
| Paint Thinner/ Naphtha / Turpentine | Wax | Finish dissolves |
| Mineral oil | Wax | Waxy yellowish-brown stain |
| Simple scratch test | Wax | Scratch marks |
