Types of Wood Finish and How to Choose - The Spruce

Wood finish is a protective coating on your wood projects such as fencing and furniture that prevents damage from UV radiation, rain, or high humidity. If left unprotected, these environmental factors can result in the wood drying out, cracking, swelling, or rotting. There are different types of wood finishes for different projects and knowing how to choose the right one will keep your project in beautiful condition for a long to come.

Types of Wood Finishes

Wood finishes can be split into two primary types based on how the finish interacts with the wood, the appearance of the wood, and the level of protection afforded to the project. These two types include penetrating wood finishes, like tung oil, linseed oil, or cedar oil, and surface wood finishes, like varnish, polyurethane, or paint.

Stains and Paints

• Stain is commonly used to protect decks and fences from water and UV radiation in order to prevent cracking, drying, or rotting. Wood stain enhances the grain pattern of the wood and it is available in a wide variety of colors.
• Paint, like stain, comes in a wide range of colors. However, wood paint is intended to fully cover the target surface, instead of allowing the natural appearance of the wood to show through. It can be used for both indoor and outdoor projects, including wood paneling, walls, doors, fences, decks, and furniture.

Penetrating Oils

Penetrating wood finishes tend to give wood projects a more natural appearance. As the name suggests, these wood finishes penetrate deep into the wood, providing protection against drying, cracking, swelling, and rotting.

• Tung oil is an environmentally friendly wood finish that accentuates the natural appearance of the wood while adding a warm, golden glow. It has a high level of durability and resistance, making it suitable for boat decks and floors. Apply tung oil with a cloth or brush for best results.
• Linseed oil is easy to apply using a brush or cloth, though this product tends to take a long time to fully cure. Use this wood finish for a natural look with a warm, yellow matte tone that darkens with age.
• Danish oil is a highly durable wood finish that is made by mixing boiled linseed or tung oil, varnish, and paint thinner. It is regularly applied with a cloth or brush to coat wooden utensils and handles for a natural matte or gloss finish.
• Cedar oil is a popular option that has a woody odor and it's known to help protect woodworking projects from insects, swelling, and rot. This wood finish has a warm, silvery-grey appearance that is great for floors and furniture.

Polyurethane

Polyurethane is the most durable option for indoor woodworking projects. It's highly effective at protecting cabinets, doors, furniture, and floors from scratches and abrasive damage. Polyurethane is also water-resistant and is intended to enhance the natural appearance of the wood with a satin or mid-gloss finish.

Shellac

Shellac has an attractive mellow finish that is intended to accentuate the natural grain of the wood. It is especially attractive on walnut and mahogany. Use a sprayer or a badger hair brush to apply shellac and choose from a range of color tones, like blonde or rich orange.

Lacquer

Lacquer is another wood finish that is made by combining several other finishes, such as shellac, urushiol, or nitrocellulose. It's great for protecting wooden furniture, cabinets, doors, or shelving, and it can be applied with a sprayer or a natural bristle brush.

Varnish

Varnish is made for outdoor application due to its high resistance to UV radiation and moisture. This wood finish is typically transparent, though some products can have a yellow or orange tint. Apply varnish with a sprayer or a paint roller for the best results.

Wax

Wax is an easy-to-apply wood finish that is ideal for hardwood floors and fine wooden furniture. Use a cloth, brush, or sprayer to apply the wax to the wood for increased physical and environmental protection.

Buying Considerations for Wood Finish

• Durability and Resistances: Wood finishes protect woodworking projects by providing a physical layer that can prevent damage from scratches, chemical abrasions, and solvents. Choose a UV and moisture-resistant wood finish for outdoor projects to prevent cracking, drying, swelling, and rot.
  
• Ease of Use: Consider how the finish is applied whether with a brush, cloth, or sprayer. Without experience, a sprayer may be trickier on high-quality projects like fine furniture.
• Application Method: Not every wood finish can be applied using the same method. Some wood finishes are made for use with a fabric dabber, while others can be applied with a paint roller. Take an honest assessment of your skills and decide which finish calls for a method you can apply correctly.
• Appearance: The final appearance can vary depending on the finish type. Water-based finishes maintain wood's natural look, while paint or wood stain can obscure the grain for a uniform finish. Varnishes and oils give the wood a natural appearance and may have a slight yellow or golden tinge. Shellac and lacquers give the wood a deep, rich appearance.
  
• Drying Time: To get the desired result, make sure the wood finish has enough time to properly dry and to fully cure. This timeline can differ depending on the wood finish, so check the manufacturer's information for the suggested drying time.
  
  

How to Choose a Wood Finish

Before grabbing the first wood finish you spot on the shelf, take time to consider a few pieces of information that can help you narrow down the product selection.

The type of wood finish determines physical durability & environmental resistance. Varnishes protect against everyday wear and tear, UV radiation, and water but use a marine-grade finish for outdoor wood fully exposed to the elements. A polyurethane wood finish will be sufficient for pieces that remain indoors and aren't concerned with UV ray protection. Research the various wood finishes before deciding which is best for your project.

1 Inspect your wood project

Start by making a thorough inspection of the wood. Make note of any holes, cracks, splits or loose joints that need to be repaired. These are always best completed prior to staining and finishing your wood project.

2 Fill holes and cracks

Small holes and cracks in the wood can be filled using Minwax® Stainable Wood Filler. Don’t smear the wood filler around the hole, as that will require additional sanding to remove the excess. Instead, use the tip of a screwdriver to carefully pack the wood filler into the hole, mounding it slightly to allow for shrinkage as it dries.

3 Don’t skip the sanding!

Sanding is a critical step in the wood preparation process for several reasons.

It smooths out the dried Minwax® Stainable Wood Filler, removes minor nicks and scratches, and opens the pores of the wood to accept more stain. Sanding also removes the surface glaze created by the heat from the factory’s planer blades as they come in contact with the natural resins in the wood. Left unsanded, this glaze can prevent stain or finish from entering the pores.

4 Test, Test, Test

Wood is unpredictable. Always test any technique, material or product on an inconspicuous spot before you proceed with the wood project.

5 Always use pre-stain wood conditioner

Since wood pores are irregular, use Minwax® Pre-Stain Wood Conditioner before you stain to reduce the likelihood of blotchiness.
