Deciding between varnish and stain for a wood finishing project can be confusing. Both products enhance and protect wood surfaces, but they achieve the desired look in different ways. This comprehensive guide examines the key differences between varnishes and stains to help you choose the best option for your needs.

What is Varnish?

Varnish is a clear, hard-drying finish that forms a protective coating on wood. The primary component is resin dissolved in a solvent, along with drying oils and other additives. When the solvent evaporates, the resins harden into a transparent layer.

Some key features of varnish:

It forms a smooth, durable, plastic-like surface on wood that resists moisture, heat, scratches and chemical damage. This makes varnish well-suited for tabletops and surfaces subject to frequent use and handling.
Varnish enhances the natural color and grain of wood. It provides a rich, warm, glowing sheen in finishes ranging from satin to high gloss.
It dries slower than many other finishes, allowing brush strokes to level out. This makes varnish excellent for achieving an even, smooth surface.
Multiple coats can be applied for added protection and sheen. But varnish does not penetrate the wood, merely forming a coating over the surface.
It provides UV protection to reduce sun damage and fading over time.
Varnish is available in different resin types. Common options include polyurethane, acrylic, and spar varnish. Each has particular benefits depending on the project.

In summary, varnish provides a durable yet elegant finish that accentuates the natural beauty of wood. It excels at protecting tabletops, flooring, cabinets, and other surfaces from daily wear and tear.

What is Stain?

Wood stain contains pigments or dyes suspended in a vehicle like oil, water or alcohol. It penetrates into the wood, coloring the material while allowing the texture and grain to show through.

Key characteristics of stain include:

It produces transparent colors that range from rich natural wood tones to bright opaque hues like black, white or pastels. This allows for dramatic color changes to wood.
Stain accentuates the natural grain patterns and texture of wood. The color often appears uneven, with more absorption into soft grain.
It soaks into the wood pores rather than forming a coating on the surface. This allows the texture to remain felt.
Only one coat is needed in most cases. Stain does not provide a thick protective film like varnish.
Common stain types include oil-based, water-based, gel stains and chemical stains. Each has particular benefits suited to certain projects.

In summary, stains add color while showcasing the wood’s natural grain and texture. They allow for creative, translucent coloring effects not possible with paints or solid stains.

Varnish vs. Stain Comparison

Now that we’ve covered the basics of each product, let’s compare varnish and stain in greater detail across several categories:

Application

Varnish – Applied with a brush, cloth or sprayer in multiple coats. Levels smoothly. Dries slowly for an even finish. Can be applied over stain or directly to raw wood.

Stain – Normally applied with a brush or cloth in just one coat. Penetrates rapidly into wood. Can create an uneven, blotchy appearance on some woods. Used under varnish for added color.

Look

Varnish – Forms a clear, uniform glossy or satin coating over the wood surface. Enhances natural color and grain subtly.

Stain – Transparentcolored look that unevenly accentuates grain texture. Dramatically alters color from natural wood tones to opaque shades.

Protection

Varnish – Excellent moisture, heat and chemical resistance. Protects against scratches, scuffs and UV damage. Provides a durable finish.

Stain – Minimal protection of wood surface. Especially vulnerable to moisture damage. Requires a topcoat like varnish if protection is needed.

Use Cases

Varnish – Ideal for tabletops, workbenches, flooring, cabinets, and high-use surfaces where durability is key. Also used on musical instruments.

Stain – Often used on furniture, cabinetry, doors, trim and millwork to add color while showing off wood grain. Works well on porous woods like oak or pine.

Maintenance

Varnish – Withstands cleaning chemicals and moisture. But alcohol or abrasives can damage the coating over time. Recoating is needed less often than with stain.

Stain – Absorbs dirt, requires more frequent recoating to maintain appearance. Water spots are common without a protective topcoat. Touch ups can be blotchy.

Cost

Varnish – Slightly more expensive than stain. But the higher cost is worth the added durability and longevity of finish.

Stain – Very economical option for coloring wood. But may require frequent reapplication and additional topcoat for protection.

When to Use Varnish vs. Stain

With their different characteristics in mind, here are some general guidelines on when to choose varnish or stain for wood projects:

Use Varnish When You Want:

Maximum protection from moisture, scratches and UV damage
An elegant, uniform glossy or satin sheen
To mildly enhance the natural wood color/grain
A durable finish for high-use surfaces

Use Stain When You Want:

To dramatically change the color of wood
To create an uneven, natural transparent colored look
To accentuate the wood grain and texture
A simple application without too many coats

Stain and varnish can also be used together to get the best of both products. The stain provides color while the varnish gives a protective topcoat. For example, staining then varnishing outdoor furniture helps the color last longer than stain alone.

Types of Varnish and Stain

There are many varieties of varnish and stain products available. Here is an overview of the most common options and their best uses:

Varnish Types

Polyurethane – Most popular option. Extremely durable, moisture resistant finish. Ideal for floors, furniture and outdoor projects.

Spar Varnish – Excellent UV protection for outdoor and marine use. Withstands sun exposure well.

Acrylic Varnish – Fast drying and non-yellowing finish. Used on woodwork, cabinets, trim and crafts.

Nitrocellulose Lacquer – Very durable, quick drying and non-ambering. Used on furniture and musical instruments.

Shellac – Classic varnish made from resin secreted by the lac beetle. Adds a warm amber glow. Used on antiques and fine woodworking.

Stain Types

Oil-Based – Penetrate deep for an even color. Enhance grain well. Often used before varnishing.

Water-Based – Low odor, fast drying and easy cleanup. Produce a more uniform stain color.

Gel Stains – Thick consistency useful on uneven surfaces. Help avoid blotchiness on problem woods.

Chemical Stains – Reactive stains that create gray/black patinas. Used on metals as well as wood.

Aging Solutions – Mixed with paint strippers to artificially age new wood. Creates a weathered, antique look.

How to Apply Varnish vs. Stain

While varnish and stain share some similar application techniques, there are some key differences to be aware of:

Applying Varnish

Ensure the wood surface is clean, dry and lightly sanded for the first coat
Use a high-quality natural bristle brush and apply in the direction of the grain
Maintain a wet edge as you brush and overlap strokes
Let varnish dry fully before sanding lightly and applying the next coat
Tip: Thin the first coat ~10% to help penetration into the wood

Applying Stain

Pre-condition very dry or porous woods with stain diluted in solvent
Use a clean lint-free rag or foam applicator to wipe on stain evenly with the grain
Remove excess stain after 2-5 minutes before it completely dries
Q-tips help apply stain into crevices and hard to reach spots
Consider using gel stain for more control on blotchy wood species

Always read the product instructions and safety precautions before applying any finish. Proper prep, brush technique and drying between coats helps ensure optimal results.

maintenance

Varnish and stain each require some maintenance to keep looking their best on wood surfaces:

Varnish Maintenance:

Dust frequently and clean with mild soap and water
Recoat yearly or when worn to refresh protection and gloss
Lightly sand between coats to ensure adhesion
Use solvents sparingly, as they can damage the coating

Stain Maintenance:

Dust and vacuum regularly to prevent dirt buildup
Recoat every 1-2 years or whenever color appears faded
Spot treatment of worn areas may appear blotchy
Use a protective topcoat like polyurethane varnish for easier upkeep

With proper care, both varnish and stain finishes can last for many years before needing to be refinished or stripped.

Frequently Asked Questions

Can you apply varnish over stain?

Yes, it is common to stain wood first for color then apply several coats of varnish over it. The varnish provides a protective layer while allowing the stained color to show through.

Does stain provide waterproofing?

No, stain soaks into the wood so it offers very little water resistance. Always apply a waterproof topcoat like varnish or polyurethane if weatherproofing is needed.

Is gel stain better than liquid?

Gel stains offer some advantages – they help avoid blotchiness on open woods like pine, sit on the surface longer and are easier to control. But liquid stains tend to penetrate deeper and look more natural.

How long does varnish take to dry?

Drying time depends on the varnish but is usually around 2-4 hours between coats. Oil-based varnishes take the longest. High humidity also extends the drying time significantly.

Can you apply water-based polyurethane over oil-based stain?

Yes, you can safely apply water-based polyurethane or most other water-based finishes over an oil stain. Just ensure the stain has fully dried first.

Conclusion

Whether choosing varnish or stain, proper preparation and application is key to achieving the beautiful wood finish you envision. Consider the unique benefits of each – varnish for protection and stain for color. With careful selection and use, you can enhance and safeguard your woodworking projects to last for generations. Test samples on scrap wood first and allow sufficient drying time between coats. And always check the manufacturer’s directions for the products you choose. With some basic know-how, you can use varnish, stains or the two combined to bring out the very best in your wood furniture, cabinetry or flooring.
