What is a Top Nailed Wood Floor? (5 Key Benefits for Your Home)
When I run my hand across a wood floor, what I’m really connecting with is the texture—the slight ridges that form where the boards meet, the unique grain that tells the story of growth rings, and sometimes even the subtle imperfections that make each plank unique. Texture grounds a space. It’s what gives wood floors their soul and makes them more than just a surface to walk on. Among all the ways to install hardwood floors, one method that has always fascinated me is the top nailed wood floor. It’s a style that celebrates texture not only in the wood itself but also in how it’s fastened down—visible nails included.
What is a Top Nailed Wood Floor?
Let me break it down simply: a top nailed wood floor is hardwood flooring where the boards are secured by nails driven straight down through their surface. Unlike more common methods where nails are hidden—like blind nailing where nails go through the tongue of the board and are concealed—top nailing leaves the nail heads exposed on the floor’s surface.
This approach is often used with wider or thicker solid planks and reclaimed wood floors. The visible nail heads aren’t just functional; they add rustic charm and authenticity that many homeowners find appealing. You’ll usually notice these floors in older homes restored to preserve their original character or in new builds aiming for a vintage, farmhouse, or industrial look.
How Does Top Nailing Work?
Top nailing involves driving nails straight down through the face of each plank into the subfloor below. The nails used are typically longer and thicker than those used in blind nailing because they have to pass through the entire thickness of the board and securely embed into the subfloor.
After nailing, the nail heads are often countersunk slightly below the wood surface and can be either left exposed for that rugged look or filled with wood filler and sanded smooth for a cleaner finish. The choice depends on your design preference.
I usually recommend ring shank or spiral nails because their design helps them grip firmly, preventing the nails from backing out over time.
When Would You Use Top Nailing?
Top nailing isn’t for every floor. It’s best suited for:
- Wide plank flooring: Boards 5 inches or wider often require stronger fastening due to their size.
- Thicker boards: Typically ¾ inch or more in thickness.
- Reclaimed wood floors: Where visible nail heads contribute to the floor’s story.
- Floors where extra holding power is needed: Like older homes with uneven subfloors or areas prone to humidity changes.
From my years installing floors, I’ve learned that top nailing can be a lifesaver in these situations.
Why Do Some People Prefer Visible Nails on Their Wood Floor?
You might be wondering: aren’t exposed nails uncomfortable or unattractive? Actually, when done right, visible nail heads can become a beautiful design element.
In fact, visible nails add texture that you can both see and feel. They create rhythm and pattern on the floor while telling a story of craftsmanship and durability. For many clients, especially those renovating older homes or aiming for a rustic look, this is exactly what they want.
The Aesthetic Appeal
In one project I did for a client restoring an early 1900s farmhouse, we used wide pine boards with top nailing using hand-forged nails. The result was stunning—a floor that looked like it belonged to another century yet felt sturdy enough for modern living. Friends of my client often remarked on how the floors had “character,” noting how those tiny nail heads brought warmth and texture.
Visible nail heads also catch light differently than bare wood surfaces, adding subtle sparkle and depth. Some homeowners even choose to let the nail heads develop a patina over time, enhancing their antique feel.
5 Key Benefits of a Top Nailed Wood Floor for Your Home
After spending years working on all kinds of hardwood projects, I can confidently say that top nailed floors offer unique advantages you won’t find in other installation methods.
1. Superior Durability and Holding Power
The primary reason I often recommend top nailing is how secure it makes the floor. Driving nails directly through thick boards into the subfloor creates a very tight bond that resists movement.
Wood floors naturally expand and contract as humidity levels change. This movement can loosen boards if they aren’t fastened properly, causing squeaks, gaps, or uneven surfaces. Top nailed floors reduce these problems because they’re anchored firmly from the surface down.
In fact, a 2022 study by the National Wood Flooring Association (NWFA) found that floors installed with top nails experienced 25% fewer issues related to plank loosening or shifting compared to blind nailed floors in climates with significant humidity swings.
I’ve seen this firsthand in homes located in humid regions where traditional blind nailed floors would start creaking or developing gaps after just a few years. In contrast, top nailed floors remained stable and quiet for decades.
2. Adds Authenticity and Design Character
Visible nail heads create an unmistakable aesthetic that speaks to craftsmanship and history. If you want your floor to look like it has a story, top nailing helps you achieve that.
I worked on a project where we reclaimed old barn wood for flooring. We kept the original hand-forged nails visible, leaving some slight rusting intact for authenticity. The homeowners loved how this brought history right into their living room—it wasn’t just flooring; it was a conversation piece.
Even when opting for new wood, using top nailing with carefully selected nail types and spacing can mimic vintage floors beautifully.
3. Better Performance with Thick Wide Planks
When you install wide or thick planks (5 inches or more wide; ¾ inch thick), top nailing provides better stability than other fastening methods.
Wide boards are more prone to cupping (edges rising higher than center) or warping because they respond to moisture differently across their width. Top nails help hold these boards flat against the subfloor better than blind nails alone.
During one job in a coastal home with large pine planks, we tested two areas: one with blind nails only, the other with top nails plus blind nailing. After six months of humid summers and dry winters, the top nailed sections showed significantly less cupping and gaps.
A technical paper from the University of Maine’s Wood Products Lab confirms this: top nailed installations reduce cupping by up to 30% compared to blind nailed ones under fluctuating humidity conditions.
4. Easier Repairs and Maintenance
Another advantage of visible nails is accessibility when repairs are needed. If a plank gets damaged—maybe scratched by pet claws or cracked from heavy furniture—you can remove individual boards without disturbing surrounding ones too much because you can directly access each nail.
One client once spilled red wine on their reclaimed oak floor section. We patched only that plank by pulling out its visible nails carefully and replacing it without dismantling large areas of flooring—saving them time and money.
5. Cost-Effectiveness in Certain Projects
While it might seem that using long nails driven straight through the boards would increase cost due to materials or labor, in many cases top nailing actually speeds up installation and reduces expenses for wide plank projects.
Blind nailing requires careful alignment to avoid splitting tongues and precise hammering angles to hide nails properly—which takes more time. With top nailing, you’re working directly on flat surfaces and don’t have to worry about tongue damage as much.
Contractor surveys indicate installation costs can drop between 10-15% for wide plank floors installed with top nails compared to blind nailed methods because of faster work pace.
Diving Deeper into Installation Techniques
Let’s get technical for a moment about how top nailed floors come together because understanding this process helps you appreciate why it works well for certain projects.
Tools and Materials You’ll Need
- Ring shank or spiral shank nails: These have ridges along their shafts creating extra grip.
- Nail set: A small tool used to countersink nail heads below wood surface.
- Hammer or pneumatic flooring nailer: Depending on volume.
- Wood filler or putty: To fill countersunk nail holes (optional).
- Wide planks (¾ inch thick recommended): Thinner boards are at risk of splitting when nailed through.
- Moisture meter: To check wood moisture content before installation.
- Sander and finishing supplies: For post-install sanding and finishing after installation.
Step-by-Step Installation Overview
- Preparation: Acclimate your hardwood planks inside your home for at least 5-7 days so they adjust to indoor humidity.
- Subfloor inspection: Make sure your subfloor is clean, dry, level, and structurally sound.
- Layout planning: Lay out your boards dry to plan staggering seams properly.
- Nailing: Start at one wall and drive ring shank nails through each plank every 6-8 inches along edges and at midpoints for stability.
- Countersinking: Use your nail set to sink nails slightly below surface.
- Filling: If desired, fill countersunk holes with matching wood putty or filler.
- Sanding & finishing: Sand entire floor smoothly after installation then apply your preferred finish such as oil-based polyurethane or natural oils.
Tips I Share With Customers Before Starting Installation
- Always check moisture levels in both subfloor and hardwood; moisture mismatch leads to problems.
- Use thicker boards (¾ inch minimum) for best results with top nailing.
- If you want visible nails but don’t want them rusty or rough, choose galvanized or stainless steel nails.
- Practice countersinking on scrap pieces before doing whole floor—too deep can weaken wood around nail; too shallow causes raised nail heads.
- Be patient when filling holes—let filler dry fully before sanding for smooth finish.
Real-Life Case Studies
Case Study 1: Reclaimed Barnwood Floor Transformation
A family wanted authentic reclaimed barnwood flooring in their new country home but didn’t want synthetic looking “distressed” floors manufactured today.
We sourced vintage pine planks salvaged from barns over 100 years old and installed them using traditional top nailing with hand-forged nails sourced from local blacksmiths. The nail heads were left exposed without filler to preserve authenticity.
Results:
- The floor became centerpiece of their home’s design.
- After 2 years, no loose boards or noticeable movement despite seasonal humidity swings.
- Visitors frequently commented on how “alive” the floor felt because you could feel every texture—from grain to nail head.
Case Study 2: Coastal Home Wide Plank Installation
In this coastal property with wide oak planks (6 inches wide), we combined blind nailing along tongues with additional top nailing every 12 inches across each board face.
Findings after one year:
- Minimal cupping despite salty air and fluctuating indoor moisture levels.
- Floor remained quiet without squeaks common in nearby homes using blind nails only.
- Homeowners reported quick repairs were easy thanks to accessible nails.
Frequently Asked Questions About Top Nailed Wood Floors
Q: Will exposed nails be uncomfortable underfoot?
A: Not if countersunk properly and finished well. Proper sanding smooths edges around nail heads so you won’t feel sharp points walking barefoot.
Q: What wood species work best?
A: Common choices are pine, oak, fir, maple—all dense enough to take long nails without splitting when installed carefully.
Q: Can I use top nailing over radiant heat floors?
A: Generally no; radiant heat systems require glue-down or floating installations because nails could pierce heating elements or cause uneven heat distribution.
Q: How long does installation take compared to other methods?
A: For wide plank installations, top nailing can reduce labor time by up to 20% because it’s less fiddly than tongue-and-groove blind nailing.
Maintenance Tips for Top Nailed Wood Floors
Once installed, keeping your top nailed floor looking great involves a few simple habits:
- Sweep or vacuum regularly to remove grit that can scratch surfaces—especially around nail heads where debris can accumulate.
- Use felt pads under furniture legs to prevent indentations near nail heads.
- Avoid excessive water during cleaning; use damp mop techniques with products designed for hardwood floors.
- Reapply finish every few years depending on wear patterns—pay attention around nail holes as those areas may show wear faster.
