DIY Floor Refinishing? (7 Costly Mistakes!)

(7 Costly Mistakes!)

I’m Tony, a flooring contractor for over 20 years, and I’ve seen it all when it comes to floors.

Let’s talk about something close to my heart (and feet!): Floor refinishing.

We all love the idea of sprucing up our homes and saving a few bucks along the way.

DIY projects are fantastic for that, right?

But when it comes to floor refinishing, I’ve seen too many well-intentioned DIYers stumble into some pretty expensive mistakes.

Think of it this way: You’re aiming for that magazine-worthy gleam, but end up with a costly headache.

I get it. The allure of saving money is strong.

According to a recent study by HomeAdvisor, professional floor refinishing can cost anywhere from $3 to $8 per square foot.

That can add up quickly!

However, those savings can vanish – and then some – if you’re not careful.

That’s why I’m here.

I want to share some hard-earned wisdom, so you can avoid the common pitfalls that turn DIY dreams into DIY disasters.

In this article, we’re diving deep into seven costly mistakes I’ve witnessed time and again.

Avoiding these can save you money, time, and a whole lot of frustration.

Ready to learn? Let’s get started!

Mistake #1: Skipping the Preparation Phase

Okay, picture this: You’re excited to get started, you’ve got your sander ready, and you’re eager to see that beautiful wood shine through.

But hold on a second!

Before you even think about touching that sander to your floor, you need to prep.

Trust me, this is where a lot of DIYers go wrong.

Think of it like this: You wouldn’t paint a dirty wall, would you?

The same principle applies to floor refinishing.

Why is prep so important?

Well, for starters, you need to clean the floor thoroughly.

I’m not talking about a quick sweep.

I mean a deep clean.

Remove all furniture, rugs, and anything else that’s in the way.

Then, vacuum meticulously.

You’d be surprised how much dust and debris can accumulate, even if you think your floors are clean.

Next, give the floor a good scrub with a wood floor cleaner.

Make sure to follow the manufacturer’s instructions.

You don’t want to damage the wood with harsh chemicals.

What about those pesky imperfections?

This is where the real work begins.

Take a close look at your floor.

Do you see any gaps between the boards?

Cracks?

Nail holes?

These all need to be addressed before you start sanding.

Use a wood filler that matches the color of your floor.

Apply it carefully, following the manufacturer’s instructions.

Let it dry completely before sanding.

I’ve seen people skip this step, thinking it’s not a big deal.

But trust me, it is.

Those little imperfections will become glaring eyesores once you apply the finish.

Don’t forget the details!

Remove all baseboards and trim.

This will protect them from damage during sanding and finishing.

If you’re feeling ambitious, you can even replace them with new ones for a fresh, updated look.

And speaking of details, make sure to protect yourself!

Wear a dust mask, eye protection, and earplugs.

Sanding can create a lot of dust and noise.

A real-life example:

I once had a client who tried to refinish their floors without properly prepping.

They skipped the cleaning and filling steps, thinking they could save time.

The result?

The finish looked uneven, and the imperfections were even more noticeable.

They ended up having to redo the entire project, which cost them even more time and money.

Key takeaways:

• Thorough cleaning is essential.
• Address all imperfections before sanding.
• Protect yourself and your surroundings.

By taking the time to prepare properly, you’ll set yourself up for a successful and beautiful floor refinishing project.

Mistake #2: Choosing the Wrong Finish

Okay, you’ve prepped your floor like a pro.

Now it’s time to choose a finish.

But wait!

This isn’t as simple as picking a color you like.

The type of finish you choose can have a huge impact on the durability, appearance, and overall success of your project.

I’ve seen so many DIYers get overwhelmed by the options and end up choosing the wrong finish for their needs.

Let’s break down the most common types of finishes:

• Oil-Based Polyurethane:

  This is a classic choice, known for its durability and warm, amber hue.

  It’s also relatively affordable.

  However, it has a strong odor and takes longer to dry than other options.

  It also tends to yellow over time.

• Water-Based Polyurethane:

  This is a more modern option, known for its low odor and fast drying time.

  It’s also more resistant to yellowing than oil-based polyurethane.

  However, it’s generally more expensive and may not be as durable.

• Moisture-Cured Urethane:

  This is the toughest of the urethanes and is used for gym floors and high-traffic areas.

  It’s extremely durable and chemical resistant.

  However, it’s very difficult to work with and requires specialized equipment.

• Penetrating Oil Sealers:

  These sealers penetrate the wood and provide a natural, matte finish.

  They’re easy to apply and maintain, but they don’t offer as much protection as polyurethane finishes.

  They also require regular reapplication.

• Wax:

  This is a traditional finish that provides a soft, lustrous sheen.

  It’s easy to apply and repair, but it’s not very durable and requires frequent maintenance.

How do you choose the right finish?

Consider these factors:

• Type of Wood:

  Some finishes work better with certain types of wood.

  For example, oil-based polyurethane can enhance the natural beauty of oak, while water-based polyurethane is a good choice for lighter woods like maple.

• Traffic Level:

  If you have a busy household with kids and pets, you’ll need a more durable finish like oil-based polyurethane or moisture-cured urethane.

  For low-traffic areas, a penetrating oil sealer or wax may be sufficient.

• Desired Appearance:

  Do you want a glossy, satin, or matte finish?

  Oil-based polyurethane tends to have a glossy finish, while water-based polyurethane is available in a variety of sheens.

  Penetrating oil sealers and wax provide a more natural, matte look.

• VOC Content:

  VOCs (volatile organic compounds) are chemicals that can be harmful to your health.

  If you’re concerned about VOCs, choose a low-VOC finish like water-based polyurethane.

• Your Skill Level:

  Some finishes are easier to apply than others.

  If you’re a beginner, start with a user-friendly finish like water-based polyurethane or a penetrating oil sealer.

A cautionary tale:

I once had a client who chose a wax finish for their kitchen floors.

They loved the way it looked at first, but they quickly realized it wasn’t practical for a high-traffic area.

The wax finish scratched and stained easily, and they had to reapply it every few months.

They eventually switched to a more durable polyurethane finish.

Key takeaways:

• Research different types of finishes and their properties.
• Consider your lifestyle, traffic level, and desired appearance.
• Don’t be afraid to ask for advice from a flooring professional.

Choosing the right finish is crucial for the longevity and beauty of your floors.

Take your time, do your research, and make an informed decision.

Mistake #3: Overlooking Acclimation of Materials

Imagine buying beautiful new hardwood flooring, eager to transform your living room.

You install it right away, proud of your DIY skills.

But a few weeks later, you notice something unsettling: gaps are appearing between the boards, and some are even warping.

What went wrong?

The answer is simple: you skipped the acclimation process.

What is acclimation?

Acclimation is the process of allowing wood flooring to adjust to the temperature and humidity of the room where it will be installed.

Wood is a natural material, and it expands and contracts in response to changes in temperature and humidity.

If you install wood flooring without acclimating it, it will likely warp, cup, or gap as it adjusts to its new environment.

Why is acclimation so important?

Think of it like this: You wouldn’t go from a warm room to a freezing cold one without a coat, would you?

The same principle applies to wood flooring.

It needs time to adjust to its new environment before it’s installed.

How do you acclimate wood flooring?

• Bring the flooring into the room where it will be installed.

  This should be done several days before installation.

  The longer, the better.

  I recommend at least 3-5 days.

• Stack the flooring in a way that allows air to circulate around the boards.

  Don’t stack it flat on the floor.

  Use spacers to create gaps between the layers.

• Maintain a consistent temperature and humidity level in the room.

  The ideal temperature is between 60 and 80 degrees Fahrenheit, and the ideal humidity level is between 30% and 50%.

  Use a humidifier or dehumidifier to maintain these levels, if necessary.

• Check the moisture content of the flooring with a moisture meter.

  The moisture content should be within the range recommended by the manufacturer.

  This is crucial!

A real-world disaster:

I remember a client who was in a hurry to install their new hardwood floors.

They skipped the acclimation process, thinking it was unnecessary.

Within a few weeks, their floors started to cup and warp.

They had to tear out the entire floor and start over, which cost them a lot of time and money.

Key takeaways:

• Acclimation is essential for preventing warping and gapping.
• Allow the flooring to acclimate for at least 3-5 days.
• Maintain a consistent temperature and humidity level in the room.
• Check the moisture content of the flooring with a moisture meter.

Don’t skip this crucial step! It can save you a lot of headaches down the road.

Mistake #4: Ignoring Manufacturer Instructions

You’ve chosen your finish, acclimated your materials, and you’re ready to get started.

But before you dive in, there’s one more crucial step: Read the manufacturer’s instructions.

I know, I know.

It’s tempting to skip this step and just wing it.

But trust me, ignoring the manufacturer’s instructions is a recipe for disaster.

Why are manufacturer instructions so important?

Every product is different, and manufacturers spend a lot of time developing specific instructions for their products.

These instructions are designed to ensure that you use the product correctly and achieve the best possible results.

Ignoring these instructions can lead to a variety of problems, including:

• Improper Application:

  Using the wrong application technique can result in an uneven finish, streaks, or bubbles.

• Durability Issues:

  Applying the finish too thinly or too thickly can affect its durability.

• Prolonged Drying Times:

  Using the wrong drying time can lead to a sticky or tacky finish.

• Aesthetic Mismatches:

  Mixing different products or using the wrong color can result in an undesirable appearance.

• Voiding the Warranty:

  In some cases, ignoring the manufacturer’s instructions can void the warranty on the product.

What kind of instructions should you pay attention to?

• Surface Preparation:

  The manufacturer will specify how to prepare the surface before applying the finish.

  This may include sanding, cleaning, or priming.

• Application Technique:

  The manufacturer will recommend the best way to apply the finish, whether it’s with a brush, roller, or sprayer.

• Drying Time:

  The manufacturer will specify how long to let the finish dry between coats.

• Number of Coats:

  The manufacturer will recommend the number of coats to apply for optimal durability and appearance.

• Clean Up:

  The manufacturer will specify how to clean up after applying the finish.

A personal experience:

I once worked on a project where the homeowner had ignored the manufacturer’s instructions for their new hardwood flooring.

They had used the wrong type of cleaner, which damaged the finish.

They ended up having to refinish the entire floor, which cost them a lot of money.

Key takeaways:

• Always read the manufacturer’s instructions before starting a project.
• Follow the instructions carefully.
• If you have any questions, contact the manufacturer or a flooring professional.

Don’t assume you know everything.

Take the time to read the instructions and follow them carefully.

It can save you a lot of time, money, and frustration in the long run.

Mistake #5: Rushing the Process

We live in a world of instant gratification.

We want everything done quickly and efficiently.

But when it comes to floor refinishing, patience is key.

Rushing the process can lead to a variety of problems, including:

• Uneven Sanding:

  If you sand too quickly, you may not remove all the old finish.

  This can result in an uneven appearance.

• Poor Finish Adhesion:

  If you don’t allow the finish to dry properly between coats, it may not adhere properly.

  This can lead to peeling or chipping.

• Bubbles or Streaks:

  If you apply the finish too quickly, you may trap air bubbles or create streaks.

• Soft Finish:

  If you don’t allow the finish to cure properly, it may remain soft and easily damaged.

Why is patience so important?

Each step in the floor refinishing process requires time and attention to detail.

Sanding takes time to remove the old finish and create a smooth surface.

Applying the finish takes time to ensure an even coat.

Drying takes time to allow the finish to harden.

Curing takes time to allow the finish to reach its full durability.

How can you avoid rushing the process?

• Plan Ahead:

  Don’t start a floor refinishing project if you’re short on time.

  Allow yourself plenty of time to complete each step properly.

• Take Breaks:

  If you’re feeling rushed or stressed, take a break.

  Come back to the project when you’re feeling refreshed and focused.

• Follow the Manufacturer’s Instructions:

  The manufacturer will specify the recommended drying and curing times for their product.

  Follow these instructions carefully.

• Don’t Cut Corners:

  Don’t skip steps or try to speed up the process.

  It’s better to take your time and do it right the first time.

A lesson learned the hard way:

I once had a client who was in a hurry to finish their floors before a party.

They rushed the drying process, thinking they could get away with it.

The result?

The finish remained soft and easily scratched.

They ended up having to redo the entire project after the party.

Key takeaways:

• Patience is key to a successful floor refinishing project.
• Allow plenty of time for each step.
• Follow the manufacturer’s instructions.
• Don’t cut corners.

Remember, floor refinishing is not a race.

Take your time, be patient, and enjoy the process.

The results will be worth it.

Mistake #6: Not Using the Right Tools

Imagine trying to build a house with only a hammer and a screwdriver.

It wouldn’t be very efficient, would it?

The same principle applies to floor refinishing.

Using the wrong tools can make the job much more difficult and can even damage your floors.

What are the essential tools for floor refinishing?

• Sander:

  This is the most important tool for removing the old finish and creating a smooth surface.

  There are several types of sanders available, including drum sanders, orbital sanders, and edge sanders.

  Choose the right sander for your project and skill level.

• Sandpaper:

  Use a variety of sandpaper grits to achieve the desired smoothness.

  Start with a coarse grit to remove the old finish, then gradually move to finer grits to smooth the surface.

• Vacuum:

  A good vacuum is essential for removing dust and debris after sanding.

  Use a vacuum with a HEPA filter to capture even the smallest particles.

• Applicator:

  Use a high-quality applicator to apply the finish evenly.

  There are several types of applicators available, including brushes, rollers, and pads.

  Choose the right applicator for the type of finish you’re using.

• Rags:

  Use clean, lint-free rags to wipe up spills and clean the applicator.

• Safety Gear:

  Protect yourself from dust and fumes by wearing a dust mask, eye protection, and gloves.

Why is it important to use the right tools?

• Efficiency:

  The right tools can make the job much easier and faster.

• Quality:

  The right tools can help you achieve a better finish.

• Safety:

  The right tools can help you avoid injuries.

• Floor Protection:

  Using the wrong tools can damage your floors.

A tool-related disaster:

I once had a client who tried to refinish their floors using a cheap, low-quality sander.

The sander didn’t remove the old finish evenly, and it left deep scratches in the wood.

They ended up having to hire a professional to fix the damage.

Key takeaways:

• Invest in high-quality tools.
• Choose the right tools for your project and skill level.
• Use safety gear to protect yourself.

Don’t skimp on tools!

Investing in the right tools can make a big difference in the quality and efficiency of your floor refinishing project.

Mistake #7: Failing to Plan for Maintenance

You’ve refinished your floors, and they look amazing!

You’re proud of your DIY skills and eager to show them off.

But don’t get too comfortable just yet.

Refinishing is just the first step.

To keep your floors looking their best, you need to plan for ongoing maintenance.

Why is maintenance so important?

Even the most durable finish will eventually wear down over time.

Dirt, dust, and scratches can dull the finish and damage the wood.

Regular maintenance can help prevent these problems and extend the life of your floors.

What are some common maintenance mistakes?

• Using the Wrong Cleaning Products:

  Some cleaning products can damage the finish on your floors.

  Avoid using harsh chemicals, abrasive cleaners, or oil-based soaps.

  Instead, use a pH-neutral cleaner specifically designed for wood floors.

• Over-Wetting the Floors:

  Too much water can damage wood floors.

  Always use a damp mop, not a soaking wet one.

  Dry the floors immediately after mopping.

• Neglecting to Address Wear and Tear:

  Scratches, scuffs, and dents should be addressed promptly.

  Use a touch-up kit to repair minor damage.

  For more serious damage, you may need to consult a professional.

• Failing to Use Protective Measures:

  Place mats at entrances to trap dirt and debris.

  Use furniture pads under chairs and tables to prevent scratches.

  Avoid wearing shoes with high heels or cleats on your floors.

How can you plan for ongoing maintenance?

• Develop a Cleaning Schedule:

  Sweep or vacuum your floors regularly to remove dirt and dust.

  Mop your floors as needed, using a pH-neutral cleaner.

• Inspect Your Floors Regularly:

  Look for scratches, scuffs, and dents.

  Address any damage promptly.

• Use Protective Measures:

  Place mats at entrances and use furniture pads under chairs and tables.

• Consider a Maintenance Coat:

  Depending on the type of finish you have, you may need to apply a maintenance coat every few years.

  This will help protect the finish and extend the life of your floors.

A maintenance mishap:

I once had a client who neglected to maintain their newly refinished floors.

They used harsh cleaning products and failed to address scratches and scuffs.

Within a few years, their floors looked dull and worn.

They ended up having to refinish them again.

Key takeaways:

• Maintenance is essential for preserving the finish on your floors.
• Use the right cleaning products.
• Avoid over-wetting the floors.
• Address wear and tear promptly.
• Use protective measures.
