When you think of finishing hardwood floors, one product stands head and shoulders above the rest for homeowners: polyurethane. It’s the undisputed champion for a reason. It creates an incredibly tough, clear layer that acts like armor for your wood, shielding it from scratches, spills, and the daily grind of foot traffic. This protective quality is exactly why it’s the go-to choice for homeowners seeking professional hardwood floor refinishing in Stony Brook and across Long Island. This guide will walk you through everything you need to know.
The Enduring Appeal of Polyurethane Finishes
For decades, polyurethane has been the workhorse for professional Long Island hardwood floor refinishing projects, and it’s not hard to see why. Its main job is to seal the wood’s pores, creating a plastic-like shield right on the surface that defends against damage. This makes wiping up spills a breeze and stops stains from seeping deep into the wood grain.
Unlike old-school finishes like wax or shellac that needed constant upkeep, a properly applied polyurethane coat can easily last for a decade or more with just basic care. It’s a true long-term solution that preserves your floor’s integrity, whether it’s in a busy kitchen in Stony Brook or a formal dining room in a Park Slope brownstone.
Key Benefits for Homeowners
So, what makes polyurethane such a trusted friend to homeowners? It boils down to a few core advantages that make a real difference in your home and daily life.
- Exceptional Durability: It cures into a hard, resilient surface that holds its own against pets, kids, and sliding furniture. This means far fewer scuffs and scratches to worry about.
- Low Maintenance: Once the finish has cured, cleaning is simple. A quick sweep and an occasional mop with a wood-safe cleaner are pretty much all you need to do.
- Enhanced Beauty: Polyurethane doesn’t just protect; it makes the wood look incredible. It pulls out the natural grain and color, adding a wonderful depth and richness. You also get to pick the sheen—from a subtle matte or satin to a striking semi-gloss or high-gloss—to get the perfect look for your home.
- Moisture Resistance: That protective barrier is a lifesaver against water and other spills. It stops liquids from soaking into the wood, which helps prevent warping and other moisture-related damage.
For many homeowners we work with, the decision to refinish is about both protection and a fresh look. A new coat of polyurethane can completely transform a room, making old, tired floors look vibrant and new again.
Before you jump in, it’s smart to understand the entire process from start to finish. For a closer look at what a full project involves, check out our guide on professional wood floor refinishing. This durable and beautiful finish is a real investment in your home’s value and longevity.
Choosing the Right Polyurethane for Your Floors
The first big decision you’ll make when finishing your hardwood floors is picking the right polyurethane. This isn’t just a minor detail—it’s a choice that completely defines the final look, durability, and even the air quality in your home during the project. It’s a key part of any hardwood floor refinishing in Stony Brook.
It really comes down to oil-based versus water-based polyurethane. Each has its own personality, and the right one depends on your home and lifestyle.
For instance, a busy family with kids and pets in a Park Slope brownstone would likely lean toward a fast-drying, low-odor finish to get their space back up and running. But if you own a historic colonial in Stony Brook, you might want the deep, amber glow that only oil-based polyurethane can provide, making those classic red oak floors pop.
Oil-Based Polyurethane: The Traditional Choice
For decades, oil-based polyurethane was the undisputed king. It’s loved for its serious durability and the rich, warm tone it gives the wood. It soaks deeper into the grain, creating a tough, protective shield that holds up beautifully against heavy foot traffic. Over time, it develops a signature amber color that many people feel adds character to woods like oak and maple.
But this old-school option has its downsides. Oil-based finishes are packed with Volatile Organic Compounds (VOCs), which means strong, lingering fumes while you’re applying it and as it cures. And speaking of curing, it’s a slow process. It can take up to 30 days to fully harden, so you’ll have to be patient before dragging heavy furniture back into the room.
Water-Based Polyurethane: The Modern Alternative
Lately, water-based polyurethane has become the go-to for homeowners who are mindful of fumes and tight schedules. The biggest draws? Low VOCs, barely any odor, and an incredibly fast drying time. You can often get multiple coats down in a single day, which really speeds up your Long Island hardwood floor refinishing project.
Unlike its oil-based cousin, water-based poly dries completely clear and stays that way. It won’t alter the natural color of your wood, making it the perfect choice for lighter species like maple or for any floor where you want to avoid that yellowish tint. While the first-generation formulas weren’t as tough, today’s water-based finishes are incredibly resilient. In fact, they now make up nearly 50%-60% of all polyurethane floor coatings used worldwide, largely because of these benefits. You can read more about current trends in the hardwood flooring market.
This image gives you a great look at floor preparation, which is the absolute most important step before any polyurethane goes down. Whether you choose water-based or oil-based, proper sanding and cleaning create the perfect canvas for the finish to grab onto, ensuring a smooth, long-lasting result.
Deciding between water-based and oil-based polyurethane is a common crossroads for homeowners. To make it easier, here’s a quick breakdown of what matters most.
Water-Based vs Oil-Based Polyurethane: A Quick Comparison
| Feature | Water-Based Polyurethane | Oil-Based Polyurethane |
|---|---|---|
| Appearance | Dries crystal clear, preserving the wood’s natural color. | Adds a warm, amber hue that deepens over time. |
| Durability | Modern formulas are extremely tough and resist scratches. | Very hard and durable, known for its long-term protection. |
| Dry Time | Dries in 2-4 hours per coat. Can apply multiple coats a day. | Takes 8-12 hours to dry between coats. |
| Curing Time | Fully cures in about 7 days. | Can take up to 30 days to fully cure. |
| Odor & VOCs | Low odor and low VOCs. Much more pleasant to be around. | Strong chemical smell and high VOCs. Requires ventilation. |
| Best For… | Lighter woods, modern aesthetics, and homes with kids or pets. | Traditional woods, achieving a classic look, and high-traffic areas. |
Ultimately, there’s no single “best” choice—just the best choice for your project. This table should give you a clear starting point for figuring out which one aligns with your goals.
Sheen Selection: Matte to High-Gloss
Once you’ve picked your base, you need to choose a sheen. This determines how much light your floor reflects and can totally transform the feel of a room.
- Matte: Gives you that raw, natural-wood look with almost zero shine. It’s fantastic at hiding minor scratches, scuffs, and dust.
- Satin: By far the most popular choice. It has a subtle, low-luster glow that feels both modern and timeless.
- Semi-Gloss: This one has a noticeable shine that bounces more light around, making a room feel a bit brighter and more open.
- High-Gloss: Think of a wet, mirror-like finish. It’s highly reflective and extremely durable, often seen in commercial spaces or for a very formal, dramatic look.
When you’re deciding, think about your lifestyle. A satin finish is incredibly forgiving in a busy home, while a high-gloss floor will show every speck of dust and tiny scratch.

At the end of the day, picking the right polyurethane is what sets the stage for a beautiful finish that will last for years.
How to Properly Prep Floors for a Flawless Finish
Ask any seasoned pro, and they’ll tell you the secret to a stunning, long-lasting polyurethane finish isn’t found in the can—it’s all in the prep work. We estimate that a solid 90% of the final result hinges on how well the floor is prepared before a single drop of finish touches the wood.
Meticulous preparation is what ensures the polyurethane bonds correctly, creating that smooth, durable shield that protects your investment for years. This is where the real work happens in any hardwood floor refinishing in Stony Brook project. It’s a detailed process of cleaning, sanding, and perfecting the raw wood to create the ideal canvas. Skipping or rushing these steps is the single biggest mistake we see, and it almost always leads to bubbles, peeling, or a rough coat that fails way too soon.
Deep Cleaning and Wax Removal
Before we even think about sanding, the floor has to be completely free of contaminants. Over the years, floors collect all sorts of things—dirt, oils, furniture polish, and especially old wax finishes. These residues are the enemy of a new polyurethane coat because they prevent it from bonding with the wood.
A thorough deep cleaning is always our first order of business. We start with a specialized wood floor cleaner to lift grime that’s settled deep into the grain. If there’s any chance your floors have been waxed, a dedicated wax remover is non-negotiable. Polyurethane and wax are mortal enemies; even a tiny amount left behind can cause the new finish to delaminate and fail.
The Critical Role of Dust-Free Sanding
Sanding is the heart of the whole process. It does two crucial things: it strips away the old, damaged finish and smooths out imperfections like scratches, dings, and surface stains. For all our Long Island projects, we rely on a dust-free sanding system. This isn’t just a gimmick—it involves connecting powerful vacuums directly to our sanding equipment to capture the vast majority of wood dust right at the source.
The difference this makes is night and day. It keeps your home clean, protects your air quality, and is absolutely essential for a flawless finish. Airborne dust is the arch-nemesis of wet polyurethane; if it settles into a fresh coat, you can kiss that perfectly smooth surface goodbye.
While not every project needs a full-on aggressive sanding, for those curious about other options, you can check out our guide on whether wood floors can be refinished without sanding to learn about screening and recoating.
Navigating Sanding Grits for a Silky-Smooth Surface
Sanding isn’t a one-and-done deal. It’s a methodical progression through a sequence of different sandpaper grits, starting coarse and getting progressively finer. Sticking to this process is the only way to get a perfectly smooth surface that’s ready for finish.
- Coarse Grits (36-40): This is the heavy lifter. The first pass uses an aggressive grit to power through the old finish and level out minor imperfections in the planks.
- Medium Grits (60-80): Next, we switch to a medium grit. Its job is to erase the deeper scratches left behind by the coarse paper and really begin the smoothing process.
- Fine Grits (100-120): The final pass with a fine-grit paper is what produces that silky-smooth surface. This is the step that delivers that professional, flawless feel under your feet.
Trying to jump from a coarse grit to a fine one is a classic mistake. It leaves behind sanding marks or swirls that are practically invisible on raw wood but become glaringly obvious once the polyurethane is applied. Each step is designed to erase the marks of the one before it.
Just recently, we were restoring a red oak floor in a classic Stony Brook colonial. It had decades of wear and a few deep pet stains. By carefully working our way through the grits, we were able to completely remove the surface damage and bring back the beautiful, clean wood underneath, giving it a new life.
Tackling Edges, Corners, and Problem Spots
The big drum sander can’t get everywhere. Edges along baseboards, tight corners, closets, and stairs all need special attention with smaller handheld edgers and detail sanders. Honestly, this is often the most labor-intensive part of sanding, but it’s what separates a true professional job from a DIY attempt.
This is also our chance to address specific issues:
- Pet Stains: Dark stains from pet urine can sometimes be sanded out if they haven’t penetrated too deeply. If sanding doesn’t do the trick, we may need to use wood bleach or, in severe cases, replace the affected boards.
- Deep Scratches or Gouges: While most minor scratches vanish during the main sanding, deeper gouges need a different approach. We fill them with a color-matched wood filler after the initial pass, then sand it perfectly smooth with the rest of the floor.
The Final Clean-Up: Not Done Until It’s Pristine
Once the last sanding pass is complete, we move on to what is arguably the most critical step before the first coat of poly goes down: the final clean-up.
We start by meticulously vacuuming the entire area with a soft-bristled brush attachment, paying close attention to baseboards and corners. Then we do it again. And maybe a third time. You simply can’t over-vacuum at this stage.
After vacuuming, the final touch is to go over the entire floor with a tack cloth or a microfiber cloth lightly dampened with the right solvent (mineral spirits for oil-based poly, water for water-based). This picks up any invisible fine dust the vacuum missed. Only when the floor is perfectly clean, smooth, and dust-free is it truly ready for that first beautiful coat of polyurethane.
Mastering the Polyurethane Application Process
After all that careful prep work, this is where the magic happens. The application phase is the moment your sanded, clean floor starts to transform into the durable, beautiful surface you envisioned. Applying polyurethane isn’t just about rolling something on the floor; it’s a craft. When you get it right, the result is a smooth, professional-grade finish that makes any Long Island home look incredible.
The secret to a flawless finish? Consistency. From the very first brush stroke to the final pull of the applicator, keeping an even layer and working methodically is what separates a DIY job from a professional one. It’s how you avoid all those common headaches like lap marks, bubbles, and streaks. This is the most rewarding part of any Long Island hardwood floor refinishing project.
Start by “Cutting In” the Edges
Think of it like painting a room—you always do the trim first. We call this “cutting in,” and it’s the right way to start applying polyurethane. You’ll want to take a high-quality paintbrush and carefully apply a border of polyurethane along all the baseboards and into the corners. This gives you a clean, crisp perimeter to work from.
We typically create a 3-4 inch band around the entire room. This acts as a neat frame, letting you switch to a larger applicator for the main floor area without having to worry about bumping into the walls or getting sloppy near the trim. It’s a simple step that has a massive impact on the final quality.
Choosing Your Applicator
The tool you use to spread the polyurethane really matters. Each one offers a different feel and works best with certain types of finishes.
- Lambswool Applicator: This is the old-school, traditional choice, especially for oil-based polyurethane. It holds a ton of finish and lets you cover big areas fast, but it definitely takes some practice to get a smooth coat without bubbles.
- Synthetic Pad Applicator: For most people, this is the way to go, particularly with water-based finishes. The smooth pad makes it much easier to lay down thin, even coats, which is exactly what you want to avoid streaks.
- T-Bar Applicator: This is the tool of the pros. It’s designed for huge, open spaces and maximum efficiency. It’s essentially a long pole with a weighted applicator that pulls the finish across the floor in a perfect, uniform sheet.
For most DIY projects, a synthetic pad applicator gives you the best mix of control and professional results, making it much easier to get that perfect look when finishing hardwood floors polyurethane.
Maintain a Wet Edge to Avoid Lap Marks
If you learn only one technique, make it this one: always maintain a wet edge. This simply means you never let the edge of the polyurethane you just applied start to dry before you blend the next section into it. If an edge dries even a little, the next pass will overlap it and create a visible line—a lap mark—that you can’t get rid of.
To do this right, work in manageable sections, usually about 3-4 feet wide, running the entire length of the room. Always apply the finish parallel to the direction of the floorboards. You’ll start at the far wall and work your way backward toward the door you’ll be exiting from, making sure each new pass melts seamlessly into the wet edge of the previous one. This approach ensures the entire floor cures as a single, flawless sheet of protection.
The goal is to make the finish look like it was poured on, not painted. By keeping that edge wet, you allow the polyurethane to level itself out naturally, creating a flawless, monolithic surface.
Apply Thin Coats and Sand Between Them
It’s so tempting to lay on a thick coat just to get the job done faster, but this is one of the biggest mistakes you can make. Thick coats take forever to cure and are magnets for dust, drips, and bubbles. The professional standard is always to apply multiple thin, even coats.
After each coat is completely dry (check the can for the manufacturer’s recommended time), you need to lightly sand the entire surface. We use a very fine-grit sandpaper, usually 220-grit, for this. This step, called abrading, accomplishes two critical things:
- It smooths out any tiny dust nibs or bubbles that settled into the finish while it was drying.
- It scuffs up the surface just enough to give the next coat something to grab onto, creating a much stronger bond.
After sanding, you absolutely must vacuum up every speck of dust and then wipe the floor with a tack cloth before applying the next coat. This is what gives you that silky-smooth feel under your feet. Applying 3-4 coats can extend your floor’s lifespan by 30% to 50%, with each additional coat boosting its abrasion resistance by another 12-15%.

Caring for Your Newly Finished Hardwood Floors
The final coat of polyurethane is on, the scent of fresh finish is in the air, and your floors look absolutely stunning. It’s easy to think the job is done, but these next few weeks are the most critical part of protecting your investment. Getting through the curing phase correctly is what separates a good finish from a great one, especially when it comes to any Long Island hardwood floor refinishing project.
The single most important thing to understand is the difference between a floor that’s dry and one that’s fully cured. They are not the same thing. A floor can feel dry to the touch in just a few hours, but the chemical hardening process—the curing—takes much, much longer. Rushing this stage is a recipe for scuffs, dents, and regret.
The Curing Timeline: Dry vs. Cured
One of the biggest mistakes we see homeowners make is treating their floors as indestructible the moment they can walk on them. Polyurethane needs time to build up to its maximum hardness, and that timeline depends entirely on whether you went with a water-based or oil-based product.
- Dry to the Touch (Socks Only): This is the first milestone. After 24-48 hours, you can typically walk on the floor in your socks. No shoes, no pets, just light foot traffic.
- Light Use: Give it about 72 hours before you even think about bringing smaller furniture back. And when you do, lift every single piece. Don’t drag anything.
- Fully Cured: This is when the finish achieves its peak strength and is ready for real life. A water-based finish is usually 80% cured within 24 hours and completely cured in about 7 days. Oil-based polyurethane is a different beast—it can take a full 30 days to harden completely.
A quick but critical tip: hold off on putting down area rugs. Trapping solvents under a rug can stop the finish from curing evenly, which can leave a permanent, discolored outline of the rug on your brand-new floor. Wait until the full cure time has passed.
Protecting Your New Polyurethane Finish
Once your floors are fully cured, the game shifts to long-term maintenance. Thankfully, it’s all about simple, consistent habits. Scratches, grit, and scuffs are the primary enemies of that pristine polyurethane sheen.
The easiest win? Felt furniture pads. Put them on everything—chairs, tables, couches, dressers, you name it. This tiny, inexpensive step prevents thousands of micro-scratches that dull the finish over time.
For day-to-day cleaning, a microfiber dust mop is your best friend. It’s perfect for grabbing dust and pet hair. When you need a deeper clean, stick to a pH-neutral cleaner made specifically for hardwood floors, applied with a slightly damp microfiber mop. Never, ever use vinegar, ammonia, or all-purpose cleaners. They’re too harsh and will slowly eat away at your protective finish.
The secret to a long-lasting finish is simple: keep grit off the floor and use the right cleaning tools. A good doormat at every entrance and felt pads under all your furniture will do more to prevent damage than any cleaner can ever fix.
The Smart Maintenance Strategy: Screen and Recoat
Even with the best care, high-traffic areas like hallways and kitchens will eventually start showing their age. But you don’t have to wait until the damage is bad enough for a complete sanding and refinishing. The proactive approach is what we call a “screen and recoat.”
Typically done every 3-5 years, this is a crucial part of finishing hardwood floors polyurethane for the long haul.
The process involves lightly abrading (or “screening”) the top layer of polyurethane. This buffs out minor surface scratches and gives the new coat something to grip onto. After a deep clean, a fresh coat of poly is applied, instantly restoring the floor’s original luster and protective layer. It’s the secret to making your floors look brand new again without the dust, disruption, or cost of a full refinish.
Advanced Options and Knowing When to Call a Pro
While traditional water-based and oil-based polyurethane finishes give you beautiful, lasting results, the world of wood floor protection doesn’t stand still. For homeowners and businesses here on Long Island, newer technologies are hitting the market that offer huge advantages, especially when you absolutely cannot afford a lot of downtime.
Knowing about these options helps you make the best call for your specific project. One of the biggest leaps forward in recent years? UV-curable finishes. This stuff is a game-changer, using powerful ultraviolet light to harden the polyurethane almost instantly. It’s a premium service we offer for hardwood floor refinishing in Stony Brook and beyond.
The Rise of UV-Cure Technology
UV-cured finishes are pretty much the gold standard for speed and durability. Just imagine having your floors refinished and being able to walk on them and move furniture back in that very same day. For a busy retail shop or a home with kids and pets, that’s not just a convenience—it’s a necessity.
The process is fascinating. We apply a special photosensitive polyurethane, then roll a high-intensity UV light machine over the floor. That light kicks off an immediate chemical reaction, cross-linking the molecules to create an incredibly hard, non-toxic, and fully cured surface on the spot. If this sounds like the right fit for you, our guide on instant UV-curable finishes has even more detail.
This instant cure completely sidesteps the long waiting periods that come with traditional finishes. It’s a perfect match for the way we live and work now. The demand for faster, tougher solutions is a major driver in the global hardwood flooring market, which is valued at over USD 52.87 billion. You can find more hardwood flooring market trends on thebusinessresearchcompany.com if you’re curious about the industry’s direction.
UV-Cure vs. Traditional Polyurethane Finishes
So, how do you decide between cutting-edge tech and a tried-and-true classic? It really boils down to balancing cure time, durability, and cost. To make it simple, let’s put them head-to-head.
This table gives you a clear snapshot of how modern UV-cure technology stacks up against the polyurethane finishes most people are familiar with.
| Attribute | UV-Cure Finish | Traditional Polyurethane (Oil/Water) |
|---|---|---|
| Cure Time | Instant—fully cured in seconds. | Water-based: 7 days. Oil-based: 30 days. |
| Durability | Exceptionally hard and highly resistant to scratches and chemicals. | Very durable, but susceptible to damage during the long curing period. |
| VOCs & Odor | Extremely low to zero VOCs; no lingering smell after curing. | Water-based is low; oil-based has strong, lingering odors and high VOCs. |
| Cost | Higher initial investment due to specialized equipment and materials. | More budget-friendly for both materials and labor. |
For a growing number of homeowners and businesses, the superior resilience and zero downtime of a UV-cured finish easily justify the higher upfront cost. It’s an investment in both durability and convenience.
When a DIY Project Is Out of Its Depth
There’s a real sense of pride that comes from finishing your own hardwood floors. But some situations just aren’t cut out for a DIY approach. Knowing when to put down the sander and call a pro is crucial for protecting your investment and getting the beautiful outcome you want.
You should seriously consider hiring a professional for your Long Island hardwood floor refinishing if you run into any of these issues:
- Severe Pet Stains: Those dark, deep-set stains from pet urine can soak far deeper than the surface. Simply sanding them won’t work, and a pro will know whether wood bleach can save the board or if it needs to be replaced entirely.
- Deep Gouges or Warped Boards: Filling a single scratch is one thing. But widespread damage, warped boards from moisture, or “cupping” requires heavy-duty equipment and a skilled hand to get the floor perfectly level again.
- Previous Finish Problems: If your floor has an old wax finish that needs to be stripped, or a cheap, factory-applied aluminum oxide finish (which is notoriously tough to sand off), a pro has the right tools for the job.
- Complex Layouts: Trying to maneuver a sander and edger around tricky layouts, tight closets, and staircases is a recipe for frustration. A professional’s precision is needed to get those details right.
A professional assessment can save you from a costly, heartbreaking mistake. We once got a call for a historic home in Park Slope where the owner had tried to sand floors that were already too thin. He nearly sanded right through them. We were able to salvage the floor, but it’s a perfect example of why an expert eye is so valuable.
In the end, the goal is a gorgeous, durable floor that you’ll love for years. Whether you go with an advanced UV-cure finish or a classic polyurethane, recognizing when a project needs a professional touch is the smartest move you can make.
FAQ: Common Questions About Polyurethane Floor Finishing
Over the years, we’ve heard just about every question you can imagine when it comes to finishing hardwood floors. Let’s tackle a few of the most common ones we get from homeowners, from Setauket to the South Shore, about hardwood floor refinishing in Stony Brook. If you have a question that’s not on the list, just give our team a call—we’re always happy to help.
How Many Coats of Polyurethane Do I Really Need?
The magic number for a durable, beautiful finish is three coats of polyurethane. Think of it as building a shield for your floors. One or two coats just won’t cut it against daily life.
For those really tough spots—like the entryway of a busy Park Slope brownstone or a family kitchen in Stony Brook that sees constant action—we often recommend a fourth coat. Each layer builds on the last, creating a protective film that stands up to scratches, spills, and endless foot traffic.
Can You Just Put a New Coat of Polyurethane Over the Old One?
Yes, you can, but there’s a big “if” attached. This process, known in the industry as a “screen and recoat,” only works if the existing finish is also polyurethane and it’s in decent shape—no major peeling, chipping, or worn-down bare spots.
To do it right, the floor has to be professionally cleaned and then lightly scuffed up (or “screened”). This abrasion creates a microscopic texture that gives the new coat of poly something to grip onto. It’s absolutely not an option for floors with deep gouges or any floors that have been treated with wax-based products. The new finish just won’t stick.
A screen and recoat is all about the prep work. If the floor isn’t perfectly clean and properly abraded, the new finish will likely fail. You could end up with peeling and a much bigger headache than you started with.
How Long Until My Polyurethane Floors Are Fully Cured?
This is where a lot of people get mixed up. “Dry” doesn’t mean “cured.” While your floors might feel dry enough to walk on with socks in 24-48 hours, the finish is still soft and vulnerable. The real hardening process, or curing, takes much longer.
The timeline really depends on the type of polyurethane you choose:
- Water-Based Polyurethane: This is the faster option, typically reaching full hardness in about 7 days.
- Oil-Based Polyurethane: The traditional choice is a slow-and-steady marathon, taking up to a full 30 days to completely cure.
It’s absolutely critical to wait until the finish is fully cured before you move heavy furniture back or lay down area rugs. If you rush it, you can trap the solvents that are still evaporating from the finish. This not only stops the curing process in its tracks but can leave permanent imprints from the furniture or rug backing on your brand-new floors.
Should I Choose Water-Based or Oil-Based Polyurethane?
The best choice depends on your priorities. For a fast project with minimal odor, water-based is the winner. It dries clear, preserving the natural color of lighter woods like maple. For maximum durability and a traditional, warm amber glow that enhances woods like red oak, oil-based is an excellent choice, though it has a much longer cure time and stronger fumes. For hardwood floor refinishing in Stony Brook homes with pets and kids, we often recommend modern, durable water-based options.
