Unfinished Hardwood Matte: Essential Guide

Unfinished hardwood matte finishes offer a natural, understated look for your floors. This guide breaks down everything you need to know about choosing, preparing, and maintaining this beautiful, low-sheen option for a timeless and durable finish.

Hey there, DIY enthusiasts! Jack Shaffer here from Nailerguy. Ever looked at those gorgeous hardwood floors that seem to glow with a natural, soft light, without a hint of plastic-like shine? Chances are, you’re admiring an unfinished hardwood matte finish. It’s a popular choice for good reason: it’s elegant, it’s modern, and it lets the natural beauty of the wood shine through.

But as with any finishing choice, there’s a bit to understand to get it just right. Don’t sweat it, though! We’re going to walk through this step-by-step, making sure you understand every part of achieving that sought-after matte look for your stunning hardwood floors.

What Exactly is Unfinished Hardwood Matte?

Let’s start with the basics. When we talk about “unfinished hardwood,” we’re referring to hardwood flooring that hasn’t had any stain or protective coating applied at the factory. It comes to you in its raw state. So, what makes it “matte?” The “matte” part refers to the finish applied after installation. A matte finish is essentially a clear protective coating that dries with very little to no sheen or gloss.

Think of it as the opposite of a high-gloss finish. It absorbs light rather than reflecting it, giving the wood surface a soft, velvety, and natural appearance. This look is highly sought after for its understated elegance and its ability to highlight the wood’s grain and natural character without a distracting shine.

The Appeal of the Matte Finish

Why choose matte over gloss? There are several compelling reasons:

• Natural Beauty: A matte finish allows the true color and grain of the hardwood to be the star. It doesn’t artificially enhance or alter the wood’s inherent look.
• Modern Aesthetic: It aligns perfectly with contemporary design trends that favor clean lines and a more organic feel.
• Hides Imperfections: Scratches and dings are far less noticeable on a matte surface than on a glossy one, which is a huge plus for busy homes.
• Understated Elegance: It provides a sophisticated, high-end look that can complement a wide range of interior design styles.
• Less Slippery: For those concerned about slippery floors, a matte finish offers a bit more traction compared to high-gloss alternatives.

Choosing Your Unfinished Hardwood

Before you even think about finishing, selecting the right unfinished hardwood is crucial. This is where your floor’s character begins. Several factors come into play:

Wood Species: The Foundation of Your Floor

Every wood species has a unique color, grain pattern, and hardness. Here are some popular choices for flooring, along with their general characteristics:

Wood Species	Hardness (Janka Rating)	Typical Color	Grain Pattern	Pros	Cons
Red Oak	1290	Pinkish-brown to light reddish-brown	Prominent, straight grain	Durable, readily available, stains well	Can sometimes appear dull if not finished properly
White Oak	1360	Light to medium brown, sometimes with a grayish or yellowish cast	Similar to red oak, but often more subtle; distinct ray flecks	Very durable, water-resistant, classic look	Can be more expensive than red oak
Maple	1450	Creamy white to light brown	Fine, straight grain; can have wavy or bird’s eye patterns	Very hard and dense, clean modern look, takes stain well (though can be blotchy)	Can be difficult to stain evenly; lighter colors show dirt more easily
Hickory	1820	Creamy white to dark chocolate brown; significant color variation within the species	Often coarse, straight, and wavy	Extremely hard and durable, distinct character	High color variation can be a pro or con depending on preference; can be harder to work with
Walnut	1010	Rich dark brown, from medium to chocolate	Often straight but can be wavy; can have attractive figuring	Luxurious, deep color, beautiful grain	Softer than oak or maple, more expensive, can show dents and scratches more readily

The Janka hardness rating is a measure of the resistance of wood to denting and wear. A higher number indicates a harder, more durable wood. For high-traffic areas, woods with higher Janka ratings are generally recommended.

Board Width and Length

Unfinished hardwood comes in various widths and lengths. Wider boards often create a more modern and spacious feel, while narrower boards can give a more traditional look. Longer boards can also contribute to a sense of grandeur. Consider the scale of your room when making this decision. A grand hall might benefit from 5-inch or wider planks, while a smaller room might feel best with 2 ¼ or 3 ¼-inch planks.

Grade of the Wood

Hardwood flooring is graded based on the appearance of the wood, such as the presence of knots, mineral streaks, and color variations. Common grades include:

• Clear Grade: Very few knots or imperfections; a uniform appearance.
• Select Grade: A small number of knots and minor flaws are allowed, but the overall look is still quite uniform.
• Number 1 Common: More natural characteristics like knots and color variation are present.
• Number 2 Common: Even more knots and color variations, offering a more rustic or country feel.

For a true matte finish that highlights natural wood, the grade you choose will significantly impact the final look. A Number 1 or Number 2 Common grade can really show off the wood’s character when finished matte, while a Clear or Select grade provides a more refined, minimalist look.

Preparation is Key: Getting Ready for the Finish

This is perhaps the most critical stage. Properly preparing your unfinished hardwood floors will ensure the matte finish adheres well and looks its best for years to come. If your unfinished hardwood was just installed, it will likely need sanding first. If you purchased pre-sanded unfinished boards, you might skip some steps, but it’s always wise to check.

Sanding Your Unfinished Hardwood Floors

Sanding is essential to smooth the wood, remove any milling marks, dirt, or old finishes (if any), and create a uniform surface for the new finish. This is typically done with a drum sander for the main areas and an edge sander for perimeters. It’s a multi-step process:

1. Rough Sanding: Start with a coarse grit sandpaper (e.g., 36-40 grit) to level the floor and remove any imperfections.
2. Intermediate Sanding: Move to a medium grit (e.g., 60-80 grit) to remove the scratches left by the coarser paper.
3. Fine Sanding: Finish with a fine grit (e.g., 100-120 grit) to create a smooth surface.
4. Edging and Detail Sanding: Use an orbital sander or detail sander to sand the edges of the room, stair nosings, and around other obstacles.
5. Final Buffing (Optional but Recommended): A buffer with a fine-grit screen (e.g., 120-150 grit) can help ensure an exceptionally smooth finish and remove any remaining swirl marks.

Important Safety Note: Sanding hardwood floors creates a significant amount of fine dust. Always wear a high-quality dust mask or respirator, safety glasses, and hearing protection. Ensure good ventilation, and if using an electric sander, be mindful of the cord to avoid tripping hazards. For more on safe tool operation, check out resources from OSHA (Occupational Safety and Health Administration) on wood dust control and safe practices for power tools.

Cleaning After Sanding

This step is non-negotiable for a flawless finish. After your final sanding pass, you need to remove all dust. This usually involves:

• Vacuuming thoroughly, going over the floor multiple times.
• Wiping the floor with a tack cloth or a slightly damp (not wet!) microfiber cloth. This picks up any remaining fine dust particles.
• Pay close attention to corners and edges where dust tends to accumulate. Any residual dust will embed itself in the finish, creating a bumpy, unappealing surface.

Achieving a Smooth Surface: The Gap Filling Step

As wood expands and contracts with humidity changes, small gaps can appear between boards, or existing ones can widen. For a truly smooth matte finish, you’ll want to fill these gaps. A common method is using a wood filler mixed with the sawdust collected during sanding. This ensures a color match that’s as close as possible to the wood itself. Apply the filler with a putty knife, ensuring it’s pressed firmly into the gaps. Let it dry completely according to the manufacturer’s instructions before proceeding to the next sanding stage (if you didn’t achieve the desired smoothness in your initial sanding).

Applying the Matte Finish: Your Protective Coat

Now for the part that defines your floor’s look! There are several types of finishes that can achieve a matte effect. Oil-based and water-based polyurethane finishes are the most common. For a truly matte look, you’ll be looking for products specifically labeled “matte” or “ultra-matte.”

Types of Matte Finishes

1. Oil-Based Polyurethane (Matte):

• Pros: Very durable, deep and rich look (even in matte), generally more forgiving to apply, good for high-traffic areas.
• Cons: Strong odor (requires excellent ventilation and a respirator), long drying times (24 hours between coats is typical), limited color choices (usually clear or amber tones), can yellow slightly over time, requires mineral spirits for cleanup.

2. Water-Based Polyurethane (Matte):

• Pros: Low odor, faster drying times (often 2-4 hours between coats), clear finish that doesn’t yellow significantly, easy cleanup with soap and water.
• Cons: Can be less durable than oil-based if not a high-quality product, can sometimes raise the wood grain more if not applied properly, requires careful application to avoid a “plasticky” look if over-applied.

3. Hardwax Oils:

• Pros: Offers a very natural, “barely there” feel that is highly desirable for matte finishes, penetrated the wood rather than sitting on top, allows wood to breathe, easy to spot-repair, often available in very low-sheen options.
• Cons: Generally less durable and less water-resistant than polyurethanes, requires more frequent reapplication (every 1-3 years depending on traffic), can be more expensive upfront, can show wear in high-traffic areas more quickly if not maintained.

For a beginner, water-based polyurethanes are often recommended due to their lower odor and faster drying times, making the application process less daunting. However, for the most authentic, natural matte look, hardwax oils are a top contender.

Application Process: Step-by-Step

No matter the product, the application technique for a smooth, even matte finish is similar. Always read and follow the manufacturer’s specific instructions for the product you’ve chosen. Here’s a general guide:

1. Gather Your Supplies: You’ll need your chosen matte finish, high-quality brushes or rollers suitable for polyurethane, stir sticks, a paint tray, painter’s tape (for baseboards), and plenty of clean, lint-free cloths.
2. Prepare the Area: Ensure the room is clean, dust-free, and climate-controlled (avoid extreme temperatures or humidity, which can affect drying). Tape off any baseboards or walls you don’t want to get finish on.
3. Stir, Don’t Shake: If using polyurethane, stir the product gently with a stir stick. Shaking introduces air bubbles that can ruin your finish. If using a hardwax oil, follow specific product instructions for mixing.
4. First Coat:
   • For a roller application, dip the roller evenly into the finish (don’t overload it).
   • For a brush application, use long, even strokes, working with the grain of the wood.
   • Apply a thin, uniform coat. Avoid puddling or heavy buildup. It’s better to apply multiple thin coats than one thick one.
   • Work in sections, maintaining a wet edge to avoid lap marks.
   • Let the first coat dry completely according to the product’s instructions.
5. Light Sanding Between Coats: Once the coat is dry, very lightly sand the surface with a very fine grit sandpaper (e.g., 220 grit) or sandpaper screen. This is crucial for adhesion of subsequent coats and for achieving a super smooth finish. The goal is to knock down any dust nibs or slight roughness, not to remove the finish.
6. Clean After Sanding: Again, vacuum thoroughly and wipe down with a tack cloth or slightly damp cloth to remove all dust.
7. Subsequent Coats: Apply your second coat using the same method. For most finishes, 2-3 coats are recommended for durability. Some high-traffic areas might benefit from a fourth coat.
8. Final Coat: Apply the final coat carefully, ensuring even coverage.
9. Curing Time: This is different from drying time. Even after the finish feels dry to the touch, it takes days or even weeks for the finish to fully cure and reach its maximum hardness. Be gentle with your new floor during this period. Avoid heavy furniture, rugs, or abrasive cleaning.

Tip for Applying: For a truly seamless matte finish, especially with water-based polyurethanes, consider using a high-quality microfiber applicator pad or a good quality foam roller specifically designed for smooth finishes. Apply in long, even strokes, overlapping each pass by about 25-50% to ensure consistent coverage. Work from one side of the room to the other, always moving towards an exit.

Maintaining Your Matte Hardwood Floors

A matte finish is beautiful, but like any floor, it needs proper care to maintain its appearance and longevity. The good news is that its low sheen helps hide daily wear and tear.

Daily Care and Cleaning

• Sweep or Vacuum Regularly: Use a soft-bristle broom or a vacuum cleaner with a hard floor attachment (ensure the beater bar is turned off or raised to avoid scratching). This removes grit and debris that can scratch the finish.
• Wipe Up Spills Immediately: Address any liquid spills right away with a soft, absorbent cloth.
• Use Cleaners Sparingly: Avoid harsh chemical cleaners, ammonia-based products, or abrasive scrubbers. For routine cleaning, a damp (not wet!) mop with a pH-neutral wood floor cleaner is usually sufficient.

Protecting Your Floors

• Use Furniture Pads: Place felt or rubber pads on the legs of all furniture. This is one of the most effective ways to prevent scratches.
• Use Doormats: Place mats both inside and outside of exterior doors to trap dirt, grit, and moisture.
• Avoid High Heels and Cleats: High heels and sports cleats can easily dent or scratch even the hardest wood floors.
• Manage Humidity: Extreme fluctuations in humidity can cause wood to expand and contract excessively, leading to gapping or cupping. Maintaining a consistent indoor humidity level (typically between 35-55%) is beneficial. A good resource for understanding wood and humidity is the Wood Barn Design guide, which explains these principles simply.

Dealing with Wear and Tear

Even with the best care, wear might eventually appear in high-traffic areas. For polyurethane finishes, a recoat might be necessary after several years. This usually involves a light cleaning, a scuff sand (a very gentle sanding to provide tooth for the new coat), another thorough cleaning, and then applying one or two new coats of the matte finish. For hardwax oils, spot repairs are much easier and can often be done by simply cleaning the area and reapplying a small amount of the product.
