Types of Woodworking Finishes
There are five main categories of wood finishes to consider for your projects. Each has their own unique properties.
Oils
Wood oils like tung oil or Danish oils penetrate deep into the wood grain to accentuate natural color and texture. Oils soak directly into the wood itself, rather than leave a surface coat of resin on top like varnish.
Pros: Enhance natural wood look, easy to apply, repairable
Cons: Require more frequent reapplication, don’t offer as much protection as film finishes like varnish
Best for: All wood types, especially accenting grain in hardwoods like oak or walnut.
Stains
Stains introduce color while allowing some natural wood grain to show through. Both oil-based and water-based stains are available. Oil stains tend to be richer, while water-based stains raise the wood grain less.
Pros: Color variety, control over color depth
Cons: Can obscure natural wood variation
Best for: Softwoods like pine where color is desired. Most appropriate as preparation for a top clear protective coat.
Paint & Lacquer
Paints and lacquers offer full opaque coverage, completely masking natural wood color and grain. Multiple coats build up a thick plastic-like surface.
Pros: Unlimited color options, high durability, consistent appearance
Cons: Conceal all natural wood features
Best for: Furniture projects where consistent, uniform coloring is desired. Softer woods that will see high traffic.
Varnish
Varnish forms a clear, protective resin layer over raw wood. Both oil-based and water-based versions are common. Varnish enhances and preserves natural grain patterns.
Pros: Excellent protection, retains feel of natural wood
Cons: Brushing technique impacts appearance
Best for: Final protective topcoat over stained/oiled wood projects. Ideal for tabletops, outdoor furniture.
Wax
Wax finishes impart a low luster sheen. Beeswax and carnauba wax blends are most common. Wax soaks slightly into the wood and forms a mild protective coating.
Pros: Subtle shine, easy application
Cons: Softer, less durable finish
Best for: Small decorative items. Enhancing distressing/aging effects.
Common woodworking finish types have different characteristics and uses
Matching Woodworking Finishes to Wood Types
Certain woodworking finish types pair better with specific wood species, based on hardness, porosity, tannins, and grain patterns.
Softwoods – Pine, Fir, Cedar
Soft conifer woods often have irregular grain and absorb finishes at varying rates, which can lead to blotchy or uneven appearances. Oil or varnish stains help even out softwood coloring prior to adding a protective topcoat like polyurethane. The rich pigment levels out absorbency before the clear varnish seals uniformly.
For lighter hues, a whitewash pickling stain muted by a matte polyurethane allows softwoods??? loose grain texture to still peek through.
Hardwoods – Oak, Maple, Mahogany
Open-grained hardwoods display incredible variation in texture. Oil finishes enhance this natural depth and reveal striking grain patterns. Consider a Danish oil or wiping tung oil for their mild protective qualities combined with grain accentuation.
Alternatively, gel stains regulate absorption across tricky open hardwood pores prior to a clear satin polyurethane. The gel adheres evenly before the varnish seals consistently across the entire surface.
Exotic/Oily Woods – Rosewood, Teak
Dense exotic species often have naturally occurring protective oils. This added richness benefits from a transparent sheen to allow depth and luster to radiate. Wiping varnishes or oil-modified urethanes in gloss sheens reflect light off the wood???s saturated colors that would overwhelm paint or solid stains.
3-4 thin tung oil coats also protect oily wood???s natural density while accenting mesmerizing grain textures. Consider a beeswax paste finishing wax protective topcoat.
Selecting a Wood Finish by Application
Beyond wood type, the intended use of your woodworking project guides what finish suits it best. Consider traffic patterns, exposure to heat/liquid, and desired maintenance levels.
Furniture Finishes
Furniture calls for finishes with enough durability to withstand daily wear and tear. Oil-based polyurethanes provide superb protection for wood surfaces in a clear coat that preserves attractive grain. Satin or semi-gloss sheens resist fine scratching and liquid marks that could damage softer finishes.
Danish oils bring out depth with mild protective qualities in low-traffic furniture. Durable conversion varnish excels on formal dining set tables.
Kitchen Cabinet Finishes
Kitchens subject wood surfaces to heat, spills, and moisture. Nearly indestructible conversion varnishes withstand the rigors of heavy daily use on cabinets and trimwork. Their chemical structure resists yellowing or clouding better than softer varnishes.
For an affordable option, oil-based enamel paint provides a rock-solid opaque coating in any color. Coupled with thorough sanding and priming, enamel transforms cabinets.
Outdoor Woodworking Finishes
Outdoor wood projects demand weather-, water-, and UV-resistance. Marine-grade spar urethane remains the gold standard for exterior vertical surfaces. Its fortified resins stand up to sun, rain, and snow exposure while showcasing natural grain.
Teak and tung oils lend horizontal wood furniture modest waterproofing. Annual reapplication maintains protection on outdoor tables, benches, and lawn decor as the elements wear down the penetrating oils. For cost efficiency, go with three coats of exterior latex paint.
High-Wear Wood Surfaces
Tabletops, cutting boards, and high-traffic flooring face regular abuse. Only the most bulletproof finishes endure this level of use.
Marine epoxy resin coats create an impervious clear barrier that shrugs off liquids, knives, heat, and abrasion damage. Use bar-top epoxy for insane durability and chemical resistance.
Polyurethane rated for floors stands up to foot traffic across large expanses of oak, maple, and exotic wood flooring. Routine recoats restore the protective clear finish. Treat high-impact zones like entries with extra care.
Achieving Desired Woodworking Finish Appearances
Beyond sheer functionality, woodworkers also select finishes based on aesthetic goals. Do you want to alter the natural raw wood look or enhance it? How much luster do you desire?
Maintaining a Natural Wood Appearance
To preserve handsome wood grain patterns, oil finishes emphasize texture while allowing the depth and color variation to speak for itself. Tung and Danish oils sufficiently safeguard most furniture while boosting figure and richness.
For colorless protection of carvings, turnings, and precision joinery, opt for a crystal clear satin wipe-on varnish. Multiple thin applications safeguard wood integrity without appearing noticeably different than raw wood.
Changing Wood Color
Stains in oil- or water-based formulas allow for limitless custom colors on new wood elements or restoration projects. Combine stains with a clear sealant like polyurethane to lock in desired hues. Distressed paint layer removal through careful sanding exposes striking variations reminiscent of worn antique wood.
Enamel paint completely transforms wood color and texture across entire surfaces, ideal for refreshing drab cabinets or dated furniture paint schemes.
High-Gloss Luster
High-gloss varnishes, like marine spar urethanes or bar top epoxies, reflect the most intense sheen from subtle to dramatic wood grain patterns. Gloss varnishes also resist staining or etching from water marks. Careful sanding between multiple ultra-thin applications enhances the deep wet allure.
Alternatively, piano-finish lacquers sprayed with professional equipment create stunning mirror-like qualities across decorative wood accent surfaces. The satisfaction stemming from a hand-rubbed gloss piano lacquer demands patience and skill to execute properly.
Matte Textured Look
To mute wood grain and achieve a softened worn patina, apply oil-wax blends for a lightly weathered appearance. Choose an odour-less beeswax finish or antioxidant pine tar wax for comfort and mild protective sealing. A custom wax recipe including beeswax, carnauba wax, and walnut oil offers versatility.

Frequently Asked Questions
What are food-safe wood finishes?
Food-safe finishes for wood projects like cutting boards and salad bowls include mineral oil, beeswax, carnuba wax, and wood butter blends. Ensure they do not contain orange oil or tung oil, which can impart flavor and odors. Test rub a small area first, allowing a few days to check for any scent/taste impact.
Can you use polyurethane over oil-based stains?
Oil-based stains work extremely well paired under oil-based polyurethanes. Allow the stain a full 72 hours to cure completely before applying protective sealant. Lightly sand and wipe surface first to remove any barriers.
What finish holds up best to dogs, kids, and high traffic?
For demanding household hardwood flooring and furniture uses, oil-modified polyurethanes provide the most durable and stubborn protection. Their fortified resins resist moisture, scratches, and etching even under active demands over time.
How do I get a smooth, glass-like finish?
High-gloss varnishes like those designed for yacht and bartop use provide stunning glass-smooth finishes. Sand methodically through progressive grits, applying multiple thin wipe-on layers for a deep wet mirrored effect that highlights woodgrain. Allow full curing between careful applications.
What finish helps prevent color darkening of wood over time?
UV exposure causes color shifts in unfinished wood, as does oxidation in some wood species. A non-ambering finish like water-based or blonde shellac provides durable transparency that resists yellowing over decades. Even oil and wax finishes darken slightly.
What finish for outdoors will last longer – paint or stain?
In terms of longevity under full weathering exposure, exterior paint grades last dramatically longer than any stain. Multiple coats of quality oil- or latex-based paints prevent sideways moisture intrusion that breaks down wood cell walls. Reapply paint every 4-5 years.
How do I evenly stain new oak cabinets a dark espresso color?
Careful prep work ensures even stain absorption, especially on porous oak. Sand surface wood lightly to open grain, apply wood conditioner evenly first, allow to fully dry. Then use a gel stain not prone to lap marks for rich dark color, wiping thoroughly over entire area methodically. Seal with matte polyurethane.
