Wood Finish Selection Tool: Simplify Your Wood Finishing Choices

What are Wood Finishes?

Wood finishes are protective and decorative coatings applied to wooden surfaces whose purpose is to improve their beauty and durability. Wood finish can vary from a simple penetrating oil that enters into wooden surface, to much more complex varnishes and lacquers that are formulated to dry quickly to form a hard shell. Not only do these finishes provide protection from moisture, UV rays, and wear but they also allow the natural beauty and character of wood to shine through making it more aesthetically pleasing.

The Role of Wood Finishes in Protection and Aesthetics

Wood finishes improve beauty and shield surfaces from moisture, wear, and decay. There are different types of wood finishes, like varnish, lacquer, and oil, that offer unique textures and durability. The right finishing will help you preserve the wood’s natural charm while extending its lifespan. Hence, finishes are essential for both aesthetic appeal and long-term protection.

Understanding the Chemistry Behind Wood Finishes

The chemistry of wood finishes involves binding agents, solvents, and additives that form protective films. There are various types of wood finishes, from penetrating oils to film-forming polyurethanes, which interact differently with wood fibres. By understanding the chemical processes behind them, you will be well equipped to make the right selection of finishes that suit your wood surfaces and protect them, beautify them, and make them long-lasting.

Types of Wood Finishes

There are two types of wood finishes, finishes that penetrate the wood surface and the just acts as finish for the top surface. Both of them have different benefits and uses, which we'll learn about below -

1. Penetrating Surfaces

   Penetrating wood finish paint get absorbed into the wooden surface, which helped to create a protective layer internally and also maintain the natural look of the wood. These finishes help tp make the wood's grain and texture standout and usually have low sheen level. The different types of penetrating wood finishes are Linseed Oil, Tung Oil, Teak Oil and Wax.

   • Linseed Oil

   Derived from flax seeds, linseed oil penetrates deeply, providing a warm, amber tone and improves the wood grain.

   • Tung Oil

   It is a natural oil finish that hardens upon drying, which helps make it water resistance and a durable, matte finish. 

   • Teak Oil

   It is a penetrating oil which is specifically rich oily woods (like teak),  which provides water resistance and UV protection.

   • Wax

   Often applied over oil finishes, wax gives a soft, low-sheen look, protecting against moisture but not as durable as other finishes.

 

2. Surface Finishes

   Surface wood finish paint for wall frames and other wooden surfaces, are usually used to form a layer of protection for the wood surface, and makes it more durable. The different types  of Surface wood finishes are Lacquer, Polyurethane, Varnish, and Shellac.

   • Lacquer

   It is a durable, quick-drying finish that offers a high-gloss or satin sheen and is resistant to water and heat.

   • Polyurethane

   It is a popular, highly durable finish that provides excellent protection against moisture, scratches, and wear, available in glossy or matte.

   • Varnish

   It is a clear, hard finish that provides strong protection, with varying levels of gloss; used often for outdoor furniture.

   • Shellac

   It is a natural finish that dries quickly, giving a warm tone and medium gloss, but is less resistant to heat and moisture.

Comparing Natural vs. Synthetic Wood Finishes

Natural and synthetic wood finish types offer distinct benefits. Natural oils and waxes emphasise grain and eco-friendliness, while synthetics like polyurethane provide superior durability. The wood finish selection for your home depends on the needs, such as natural for traditional aesthetics, synthetic for high-traffic areas, and a balance between beauty, protection, and maintenance in various environments.

Difference Between a Wood Finish & Wood Stain

When to Use a Finish vs. a Stain

A wood stain helps to stain the wooden surface, while a finish helps protect it. 

You can use stains to change wood tone and finishes to seal and safeguard. Additionally, you can apply both for rich aesthetics and long-lasting protection, depending on whether colour enhancement or preservation is the primary goal. To get a better understanding, you can use our wood finish guide.

How to Layer Stains and Finishes for Desired Effects

First, apply stains to achieve depth of color, then finish with protective coats like varnish or oil. Layering improves texture, durability, and visual richness, allowing for custom finishes highlighting wood’s natural beauty while ensuring resilience. You can also use a wood finish visualiser to plan your layering of stains and finishes.

Factors to Consider while Choosing the Right Finish

When selecting from different wood finishes, consider factors like the type of wood, the project's purpose, desired appearance, and budget

Type of Wood

The type of wood you are working with significantly impacts the choice of finish. Hardwoods like oak and walnut are dense and may require finishes that penetrate deeply, such as oils or stains. Softer woods, such as pine, absorb finishes more readily and might benefit from a sealant or varnish to protect them from wear. Matching the finish to the wood type ensures the best protection and visual appeal.

Project Type

The nature of the project influences the appropriate wood finish. For indoor furniture, finishes like varnish or lacquer provide a smooth, durable surface. Outdoor projects require finishes with added UV protection and water resistance, such as marine varnish or specialized outdoor oils. Craft projects may benefit from a simple wax or oil finish to highlight the wood's natural characteristics.

Desired Finish Look

The desired aesthetic impacts the choice of wood finish types. For a rich, dark appearance, a walnut finish is ideal. A lacquer finish offers a durable, glossy finish, while gloss paint for wood provides a vibrant, high-shine look. Clear varnish for wood enhances the natural grain, offering a glossy wood finish. For a subtle effect, a wood finish matte or satin wood finish provides a low-sheen look. A wood oil finish or natural wood finish brings out the wood's innate beauty. A burned wood finish gives a rustic, distressed wood finish feel. You can take a look at our Wood Finish Visualizer  to get a better understanding of the final look. 

Budget

Budget constraints influence the wood finishes types you choose. High-end finishes like lacquer or speciality varnishes can be more costly but offer superior durability and appearance. More affordable options include oils and waxes, which provide good protection and enhance wood's natural beauty. Balancing cost with quality ensures you get a durable and attractive finish within your budget

Environmental Conditions: Indoor vs. Outdoor Use

The Wood Finish Guide 101 states that environmental conditions must also be considered when selecting the right finish. Indoor projects may use delicate oils or waxes, while outdoor wood requires weather-resistant finishes like marine varnish or exterior polyurethane. Proper wood finish selection ensures lasting performance, protecting wood from moisture, UV rays, and temperature changes.

Finishing Techniques for Different Wood Types

There are various wood types and types of wood finishes. Hardwoods and softwoods absorb finishes differently. Dense hardwoods benefit from penetrating oils, while porous softwoods may need sealing before finishing. You need to tailor the techniques like sanding, conditioning, and layering, based on the type of wood, to ensure smooth, even application and maximise each wood type's aesthetic and protective qualities.
