How Smooth Should My Refinish My Hardwood Floors? (Explained)

Imagine stepping onto your hardwood floors and feeling the smoothness beneath your feet, like gliding on glass. But how smooth should my refinished hardwood floors actually be? This question has crossed the minds of many homeowners, including myself, as I navigated the intricacies of flooring refinishing. The quest for that perfect finish can seem overwhelming, but with the right knowledge and tools, it is entirely achievable.

When I first began working in the flooring industry over 15 years ago, I encountered a myriad of refinishing projects, each with its own set of challenges and expectations. Refinishing hardwood floors is a delicate balance between achieving a flawless surface and maintaining the wood’s integrity. Understanding how smooth the floor should be not only affects aesthetics but also impacts durability and maintenance.

Understanding Smoothness in Hardwood Floor Refinishing

Smoothness in hardwood floor refinishing refers to the evenness and texture of the surface after sanding and applying finish. A perfectly smooth floor enhances the visual appeal and contributes to the longevity of the finish. However, it is essential to keep in mind that different types of wood and finishes may require varying levels of smoothness.

The Importance of Smoothness

Achieving the right level of smoothness is crucial for several reasons:

• Aesthetics: A smooth surface reflects light beautifully, enhancing the natural grain of the wood.
• Comfort: Walking on a smooth floor is more comfortable, as it reduces friction on bare feet.
• Durability: Smooth finishes are less prone to trap dirt and debris, which can lead to scratches over time.

The Refinishing Process

The refinishing process typically involves several steps, each contributing to the overall smoothness of the finished product. Let’s break down each step in detail.

Step 1: Preparation

Preparation is vital before starting any refinishing project. Here’s how I approach this stage:

1. Clearing the Area: First, I remove all furniture and any other items from the room. This creates a clear workspace and prevents damage to belongings.
2. Inspecting the Floors: Once the area is clear, I thoroughly inspect the hardwood for any damage, such as loose boards or significant scratches. If I find issue areas, I repair them before sanding begins.
3. Cleaning: I sweep and vacuum to remove dust and debris, ensuring a clean surface for sanding.

Step 2: Sanding

Sanding is arguably the most critical stage in achieving a smooth finish. Here’s how I do it:

1. Choosing the Right Equipment: Depending on the project size, I use a drum sander for large areas and an orbital sander for corners and edges. For example, during a recent project in a 1,200-square-foot home, I opted for a drum sander with 36-grit sandpaper to start.
2. Sanding Technique: I always sand with the grain of the wood to avoid scratches that run against it. For initial sanding, I start with 36 or 40-grit sandpaper to remove old finishes and imperfections.
3. Progressing Through Grits: After the initial sanding, I gradually move to finer grits—80 and then 100—to achieve a smoother surface. This progression is essential; skipping grits can leave scratches that are hard to remove later.
4. Edge Sanding: For edges and corners, I use an orbital sander or detail sander equipped with finer paper to blend everything seamlessly.

Step 3: Cleaning

After sanding, it’s crucial to clean up properly:

1. Vacuuming: I vacuum meticulously to remove all dust particles created during sanding.
2. Wiping Down: Following vacuuming, I damp mop with a microfiber cloth to pick up any remaining fine dust. This step ensures that no debris interferes with the finish application.

Step 4: Staining (if desired)

If clients want to change the color of their hardwood floors, this is where staining comes into play:

1. Choosing Stain Color: I present various stain options that complement their interior decor. It’s essential to test a small area first because colors can appear different once applied.
2. Application: I apply stain using a foam applicator or brush in long strokes, working in sections to ensure even distribution.
3. Drying Time: It’s important to let the stain dry according to manufacturer instructions before moving on to finishing.

Step 5: Finishing

Finishing provides protection and adds depth to the color:

1. Choosing Finish Type: Based on project requirements, I might opt for oil-based or water-based finishes. Oil-based finishes tend to provide greater durability but have longer drying times.
2. Application Methods: Using a roller or brush, I apply an even coat of finish across the floor, working with the grain.
3. Drying Time: Adequate drying time between coats is essential for a durable finish; typically, I wait at least 24 hours before applying a second coat.
4. Final Sanding: After applying multiple coats of finish (usually three), I lightly sand between coats with fine-grit sandpaper (220-grit) to ensure smoothness.

How Smooth Should It Be?

The smoothness level can vary based on several factors:

• Type of Finish: Oil-based finishes tend to require a smoother surface than water-based finishes due to their different application techniques.
• Wood Species: Some woods, like oak, accept finishes better and may not require as much smoothing as softer woods like pine.
• Intended Use: If the floor will be subjected to heavy traffic or pets, a smoother finish can help resist scratches and wear.

From my experience, a great target is a glass-like appearance without being overly slippery. A smooth finish typically requires sanding down to at least 120-grit before applying the final coat.

Cost Considerations with FloorTally

When estimating costs for refinishing projects, I’ve found FloorTally to be an invaluable tool. For example, when working on a 1,000-square-foot area in a residential home in Atlanta, GA, I could input local material rates for sandpaper, stains, finishes, and labor costs into FloorTally.

This allowed me to provide clients with realistic budgets upfront—something they greatly appreciated. In one instance, after entering all necessary details for a refinishing project involving both staining and finishing, FloorTally produced an estimate that was within 5% of actual costs upon completion. The accuracy of FloorTally helped me avoid underestimating costs, which is a common pitfall in our industry.

Challenges and Solutions

Every refinishing project presents unique challenges. Here are some obstacles I’ve encountered along with solutions:

Uneven Wear

One challenge I faced was uneven wear on older hardwood floors. In one project in a historic home in Charleston, SC, significant dips and scratches required more extensive work than anticipated.

I had to use a thicker layer of finish to fill in imperfections adequately while maintaining an even look. To address uneven surfaces effectively:

• Assessing Damage Early: Before starting any work, I carefully inspected for areas needing additional attention.
• Using Filler: For deep scratches or gouges, I used wood filler that matched the floor’s color before sanding.

Time Management

Time can easily slip away during refinishing projects if not managed properly. During one particularly hectic summer season, I had multiple projects lined up that started overlapping.

To manage my time effectively:

• Setting Realistic Timelines: For each project, I developed a timeline that accounted for drying times between coats.
• Communication with Clients: Keeping clients informed about progress helped manage expectations.

Tips for Achieving Smooth Floors

Achieving smooth hardwood floors requires attention to detail and proper technique. Here are some tips based on my experiences:

1. Invest in Quality Tools: Using professional-grade sanders and finishes can save time and produce better results.
2. Mind the Grit Sequence: Always progress through grits gradually; skipping grits can leave scratches that are hard to remove later.
3. Test Area: Always do a test patch before committing to your entire floor to ensure you’re happy with the color and finish.
4. Proper Ventilation: Ensure good airflow during drying to avoid dust settling on your freshly finished surfaces.
5. Temperature Control: Maintain an ideal temperature (between 60°F – 80°F) during application as it affects drying times and finish quality.
6. Use Quality Finishes: Opt for high-quality finishes that offer better durability and aesthetics.

Comparing Finishing Options

I’ve experimented with both oil-based and water-based finishes over the years:

Oil-Based Finishes

• Advantages:
  • Provide a rich color depth.
  • Generally more durable.
  • Better suited for high-traffic areas.
• Disadvantages:
  • Longer drying time (24 hours or more).
  • Strong odors during application.
  • Can yellow over time.

In my experience, oil-based finishes are excellent for environments where durability is paramount—like homes with pets or children—but require more care during application due to odors.

Water-Based Finishes

• Advantages:
  • Quick drying time (usually within hours).
  • Low odor; safer for indoor use.
  • Less chance of yellowing over time.
• Disadvantages:
  • May not provide as deep a finish initially.
  • Requires more frequent reapplication compared to oil-based finishes.

Water-based finishes have become my go-to for residential projects where homeowners prioritize quick turnaround and low VOCs (volatile organic compounds).

Maintenance of Refinished Hardwood Floors

Once you’ve achieved that perfect smooth finish on your hardwood floors, maintaining them becomes critical:

1. Regular Cleaning: Sweep or vacuum regularly using soft bristle brooms or vacuum attachments designed for hardwood floors.
2. Damp Mopping: Occasionally damp mop with a pH-neutral cleaner specifically formulated for hardwood floors—avoid harsh chemicals that can damage the finish.
3. Reapplication of Finish: Depending on traffic levels and wear patterns, you may need to reapply finish every few years to keep your floors looking new.
4. Protective Measures: Use felt pads under furniture legs and avoid walking on floors with high heels or cleats that can scratch surfaces.
