Sanding Herringbone Floors: How-To (7 Mistakes!)

“The details are not the details. They make the design.” – Charles Eames

That quote by Charles Eames really hits home when I think about herringbone floors.

The intricate pattern, the way the light plays across the wood… it’s all about the details.

And when it comes to maintaining that beauty, sanding is key.

But let me tell you, I’ve seen some real horror stories out there.

That’s why I’m here to walk you through the process, and more importantly, help you dodge the most common mistakes.

Section 1: Understanding Herringbone Floors

Okay, so what is herringbone flooring?

Basically, it’s a pattern made up of rectangular blocks arranged in a zigzag.

Think of it like a broken zigzag – each “zig” and “zag” is a separate piece of wood.

It’s been around for centuries, popping up in ancient Roman roads and fancy European castles.

Talk about timeless!

You’ll usually find herringbone made from:

• Hardwood: Oak, maple, walnut – the classics.
  
  These are durable and can be sanded down multiple times.
  
  It can add warmth and character to any space.

• Engineered Wood: Layers of wood glued together with a hardwood veneer on top.
  
  A bit more budget- friendly and stable in humid environments.

• Laminate: A synthetic material printed to look like wood.
  
  Least expensive, but can’t be sanded.
  
  It’s not the real deal but can mimic the look for less.

Why is sanding so important?

Well, over time, herringbone floors can get scratched, dented, and just plain dull.

Sanding removes that damaged surface, revealing fresh wood underneath.

It’s like giving your floor a brand-new lease on life!

Plus, it preps the surface for a new finish, which protects the wood and keeps it looking its best.

Section 2: The Sanding Process Overview

Alright, let’s get into the nitty-gritty. Here’s a simplified rundown of how sanding works:

1. Prep: Clear the room, clean the floor, and inspect for any loose blocks or protruding nails.

2. Sand: Use a drum sander (for large areas) and an edge sander (for edges and corners).

3. Fine-Tune: Hand-sand any tricky spots or areas the machines couldn’t reach.

4. Dust Removal: Vacuum everything – the floor, the walls, even yourself!

5. Finishing: Apply stain (optional) and several coats of sealant or polyurethane.

Equipment You’ll Need:

• Drum Sander: For the main floor area.
• Edge Sander: For along walls and in corners.
• Detail Sander: For more precise sanding.
• Sandpaper (various grits): Coarse, medium, fine.
• Vacuum with HEPA filter: For dust collection.
• Safety Glasses, Dust Mask, Ear Protection: Safety first!

Benefits of Sanding:

• Restores Shine: Brings back that original luster.
• Removes Imperfections: Scratches, dents, stains – gone!
• Extends Lifespan: Protects the wood from further damage.
• Increases Value: A beautifully refinished floor can boost your home’s appeal.

Safety First, Always!

• Wear safety glasses, a dust mask, and ear protection.
• Ensure proper ventilation.
• Be aware of electrical hazards.
• Never leave the sander unattended while it’s running.

Section 3: The Seven Common Mistakes to Avoid When Sanding Herringbone Floors

Okay, pay close attention, because this is where things get real.

I’ve seen these mistakes happen way too often, and they can turn a beautiful herringbone floor into a disaster zone.

Mistake #1: Skipping the Preparation Phase

I cannot stress this enough: preparation is KEY.

I mean, seriously.

Imagine trying to paint a wall without cleaning it first.

Same principle here.

Why it’s important:

• Dirt and debris can scratch the sandpaper and the floor. You’ll end up grinding the dirt into the wood, making things worse.
• Loose nails or staples can tear the sandpaper and damage the sander. Not to mention, they can become dangerous projectiles.
• An uneven surface will lead to uneven sanding. You’ll end up with some areas sanded too much and others not enough.

How to do it right:

1. Clear the room completely. Move all furniture, rugs, and anything else that might get in the way.

2. Sweep or vacuum the floor thoroughly. Get rid of all loose dirt, dust, and debris.

3. Scrub the floor with a wood cleaner. Remove any stains, grease, or grime.
   
   Let it dry completely.

4. Inspect the floor for loose blocks, protruding nails, or staples. Repair or replace any damaged blocks.
   
   Hammer down any loose nails or staples.
   
   I usually use a nail punch to drive them slightly below the surface.

5. Check for any uneven areas. If you find any, level them out with a wood filler.
   
   Let the filler dry completely and then sand it smooth.

Neglecting this step can lead to uneven sanding, scratches, and a poor finish.

Trust me, it’s worth the extra time and effort.

Mistake #2: Using the Wrong Grit Sandpaper

Think of sandpaper grit like the coarseness of a file.

A low grit number (like 24 or 36) is very coarse and removes a lot of material quickly.

A high grit number (like 120 or 220) is very fine and smooths the surface.

Why it’s important:

• Using too coarse of a grit can gouge the wood and leave deep scratches. You’ll have to spend extra time trying to sand them out, and you might even damage the floor beyond repair.
• Using too fine of a grit won’t remove the old finish or imperfections. You’ll end up wasting your time and sandpaper.

How to choose the right grit:

• Start with a coarse grit (36-40) to remove the old finish and level the surface. If your floor is heavily damaged or has multiple layers of finish, you might need to start with an even coarser grit (24).
• Move to a medium grit (60-80) to remove the scratches left by the coarse grit.
• Finish with a fine grit (100-120) to smooth the surface and prepare it for finishing. For the final pass, some pros use 150 grit for an extra-smooth finish.

Here’s a handy table to guide you:

Pro Tip: Always test the grit on a small, inconspicuous area of the floor first.

This will help you determine if it’s the right grit for the job.

Using the wrong grit sandpaper can damage the wood and result in an uneven finish.

Take your time to choose the right grit for each step of the process.

Mistake #3: Failing to Sand with the Grain

This is HUGE when it comes to herringbone floors.

Because the pattern has blocks running in different directions, it can be tricky.

Why it’s important:

• Sanding against the grain can cause visible scratches and swirl marks. These scratches will be especially noticeable after you apply the finish.
  
  Trust me, you’ll see them.
• Sanding against the grain can also damage the wood fibers. This can make the floor more susceptible to dents and scratches in the future.

How to identify the grain direction:

• Look closely at the wood. The grain is the direction in which the wood fibers run.
  
  It usually looks like lines or streaks in the wood.
• On a herringbone floor, the grain direction will alternate between the blocks. Some blocks will have the grain running parallel to the long edge, while others will have it running perpendicular.

How to sand with the grain on a herringbone floor:

• For the initial sanding, use a drum sander and sand at a 45-degree angle to the blocks. This will help you avoid sanding directly against the grain.
• For the subsequent sanding passes, use an edge sander and hand-sand the blocks individually. Sand each block in the direction of the grain.

Here’s what I do:

I usually start with the drum sander at a 45-degree angle, then switch to an edge sander and hand-sand the blocks individually.

It’s more time-consuming, but it’s the best way to ensure a smooth, scratch-free finish.

Failing to sand with the grain can result in visible scratches and damage to the wood.

Take your time to identify the grain direction and sand accordingly.

Mistake #4: Over-Sanding or Uneven Sanding

This is a balancing act.

You want to remove the old finish and imperfections, but you don’t want to remove too much wood.

Why it’s important:

• Over-sanding can thin the wood and make the floor more susceptible to damage. It can also expose the subfloor, which is not meant to be walked on.
• Uneven sanding can create dips and valleys in the floor. These will be visible after you apply the finish.

How to avoid over-sanding:

• Use the right grit sandpaper. As I mentioned earlier, start with a coarse grit and gradually move to a finer grit.
• Keep the sander moving. Don’t let it sit in one spot for too long, or you’ll end up sanding too much.
• Apply even pressure. Don’t press down too hard on the sander, or you’ll end up sanding more in some areas than others.

How to achieve an even finish:

• Overlap each pass by about 50%. This will help to blend the edges of each pass and prevent noticeable lines.
• Sand in a consistent pattern. For example, you could sand in long, straight lines or in a circular motion.
• Use a sanding block to hand-sand any areas that the sander couldn’t reach. This will help to blend those areas with the rest of the floor.

My tip:

I often use a handheld random orbital sander for the final pass.

It helps to blend everything together and create a super-smooth finish.

Over-sanding or uneven sanding can damage the wood and result in an unsightly finish.

Be patient and take your time to achieve an even, consistent result.

Mistake #5: Ignoring Dust Control

Sanding creates a lot of dust.

And I mean a lot.

It’s not just a nuisance; it can also be a health hazard.

Why it’s important:

• Dust can get into your lungs and cause respiratory problems. It can also irritate your eyes and skin.
• Dust can contaminate the finish. This can lead to bubbles, streaks, and other imperfections.
• Dust can create a fire hazard. Wood dust is highly flammable.

How to control dust:

• Use a vacuum with a HEPA filter. This will help to capture the fine dust particles that can escape a regular vacuum.
• Attach a dust collection system to your sander. Many sanders come with a dust port that you can connect to a vacuum or dust collector.
• Seal off the room with plastic sheeting. This will help to prevent dust from spreading to other parts of your house.
• Wear a dust mask or respirator. This will protect your lungs from inhaling dust particles.
• Ventilate the room. Open windows and doors to allow fresh air to circulate.

Cleaning up:

• Vacuum the floor thoroughly after each sanding pass.
• Wipe down the walls and other surfaces with a damp cloth.
• Change your clothes and take a shower. This will help to remove any dust that may have accumulated on your body.

Here’s a startling statistic:

According to the EPA, indoor air can be 2-5 times more polluted than outdoor air.

Sanding without proper dust control can significantly increase indoor air pollution.

Ignoring dust control can be hazardous to your health and can ruin your finish.

Take the necessary precautions to minimize dust exposure.

Mistake #6: Not Applying Finish Properly

You’ve spent all this time sanding your herringbone floor to perfection.

Now, it’s time to protect your investment with a good finish.

Why it’s important:

• Finish protects the wood from scratches, dents, and stains.
• Finish enhances the beauty of the wood. It can bring out the grain and add depth and richness.
• Finish makes the floor easier to clean.

Common pitfalls to avoid:

• Applying too much finish. This can lead to drips, runs, and an uneven surface.
• Applying too little finish. This can leave the wood unprotected and vulnerable to damage.
• Applying the finish in the wrong direction. Always apply the finish in the direction of the grain.
• Not allowing the finish to dry completely. This can lead to a sticky, tacky surface that attracts dirt and dust.
• Using the wrong type of applicator. Use a high- quality brush, roller, or pad that is designed for the type of finish you are using.

How to apply finish properly:

1. Read the manufacturer’s instructions carefully. Each type of finish has its own specific application requirements.
2. Prepare the floor. Make sure it’s clean, dry, and free of dust.
3. Apply a thin, even coat of finish. Use a high- quality applicator and work in the direction of the grain.
4. Allow the finish to dry completely. Follow the manufacturer’s recommended drying time.
5. Apply additional coats as needed. Most finishes require at least two coats for adequate protection.

A word of caution:

I always recommend testing the finish on a small, inconspicuous area of the floor first.

This will help you determine if you like the color and sheen of the finish.

Not applying the finish properly can ruin all your hard work.

Take your time and follow the manufacturer’s instructions to achieve a beautiful, durable finish.

Mistake #7: Neglecting Regular Maintenance Post-Sanding

You’ve sanded, finished, and now your herringbone floor looks amazing!

But don’t think you’re done.

Regular maintenance is essential to keep your floor looking its best for years to come.

Why it’s important:

• Regular cleaning removes dirt and debris that can scratch and damage the finish.
• Regular maintenance helps to prevent wear and tear.
• Regular maintenance extends the life of your floor.

How to maintain your floor:

• Sweep or vacuum regularly. This will remove loose dirt and debris.
• Mop the floor with a damp cloth or mop. Use a mild soap and water solution.
• Avoid using harsh chemicals or abrasive cleaners. These can damage the finish.
• Place mats at entrances to trap dirt and moisture.
• Use furniture pads under furniture legs to prevent scratches.
• Avoid wearing shoes with high heels or cleats on the floor.
• Re-coat the floor with finish every few years. This will help to protect the wood and keep it looking its best.

A little goes a long way:

I often tell my clients that a little bit of regular maintenance is much easier and less expensive than having to re-sand and refinish the floor every few years.

Neglecting regular maintenance can lead to premature wear and tear and can shorten the life of your floor.

Take the time to care for your floor, and it will reward you with years of beauty and enjoyment.
