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.


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. 


For applications requiring a sleek, glossy look, lacquer is the ideal choice. Available in colors ranging from bright shades to darker tones.

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 is a standard finish used on wooden surfaces to create an aesthetically pleasing look.


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.


Different wood stains are ideal for different applications and should be carefully chosen based on their intended use:

Water-Based Finish

Water-based wood finishes are ideal for increasing longevity and wood finish durability.


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.

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.


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.

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


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?
