Leveling Wood Subfloor: Fix Uneven Surfaces

Unevenness in a wood subfloor often manifests as squeaks, bouncing, and visible dips, so addressing these issues requires careful attention to underlying causes and proper techniques. Leveling a wood subfloor involves several key steps, beginning with accurate identification of the problem area, then you need to make sure that the joists are leveled, or not rotten. After that you can perform patching compounds or shimming, which ensures that the final flooring surface are stable, or aesthetically pleasing. Preparing for new flooring installation is achievable through strategic use of self-leveling compounds.

Decoding the Clues: Common Subfloor Problems and Their Indicators

Alright, detective, let’s get to the real work! It’s time to train your eye (and your ears) to recognize the signs of a troubled subfloor. Here’s a breakdown of common problems and how to spot them.

Unevenness: The Wobbly Foundation

• How to Find It: Place your level on the subfloor and check for any gaps underneath. Use your straight edge to span larger areas and identify subtle variations.
• What It Means: Unevenness can be caused by settling, warped boards, or even previous shoddy repairs.

High Spots: The Unexpected Bumps

• How to Find It: Run your hand across the subfloor. High spots will feel like raised areas that disrupt the smooth surface. The level and straight edge will also help you pinpoint these.
• What It Means: These might be nails or screws that have popped up, or areas where the subfloor is bulging.

Low Spots: The Depressing Depressions

• How to Find It: The straight edge is your best friend here. Place it on the subfloor and look for gaps underneath. Use your measuring tape to measure the depth of any depressions.
• What It Means: Low spots can indicate settling, rot, or damage from water.

Squeaks: The Annoying Orchestra

• How to Find It: Walk around the room and listen for those telltale squeaks. Pay attention to where the squeaks are coming from – that’s your prime suspect!
• What It Means: Squeaks usually mean that the subfloor is rubbing against something underneath, like a joist or another board. Loose fasteners are often to blame.

Loose Boards: The Shifty Characters

• How to Find It: Walk across the subfloor and feel for any boards that move or flex under your weight.
• What It Means: Loose boards are a sign that the fasteners (nails or screws) have come loose or are missing altogether.

Gaps: The Unwanted Openings

• How to Find It: Visually inspect the subfloor for any gaps between the boards.
• What It Means: Gaps can be caused by shrinkage, warping, or simply poor installation. They can also let in drafts and moisture.

Water Damage: The Silent Destroyer

• How to Find It: Look for stains, discoloration, or signs of mold or mildew. Use your moisture meter to check the moisture content of the wood. Soft, spongy areas are a dead giveaway.
• What It Means: Water damage can lead to rot, mold, and structural problems. It’s crucial to address it quickly.

Structural Integrity: The Big Picture

• How to Find It: Take a step back and look at the overall condition of the subfloor. Are there any major cracks, sagging areas, or other signs of instability?
• What It Means: Serious structural issues might require professional help. Don’t mess around with this one!

Tool Up: Essential Tools and Materials for Subfloor Repair

Alright, so you’ve found some gremlins in your subfloor. Don’t sweat it! Before you start swinging that hammer like a superhero, let’s make sure you’ve got the right arsenal. Think of this section as your shopping list for Operation: Level Floor. We’re breaking down the essential tools and materials, so you don’t end up improvising with a butter knife and bubblegum (trust me, I’ve seen it!).

We’re talking about the unsung heroes of subfloor repair. Let’s get you prepped with a categorized breakdown of what you’ll need!

Tools: Your Subfloor Repair Avengers

• Level (4-foot, 6-foot, or laser level): Okay, this isn’t just about hanging pictures straight; this is about ensuring your entire floor isn’t on a subtle ski slope.
  • A 4-foot level is great for smaller areas and quick checks.
  • A 6-foot level gives you a broader view of the landscape.
  • A laser level? That’s for when you want to feel like you’re in a sci-fi movie AND get a super accurate read, especially across large rooms. They each come with advantages and disadvantages.
• Measuring Tape: This one’s a no-brainer, but get a good one! Look for one with clear markings, a sturdy hook, and a lock that actually works. You want accuracy, not frustration. I cannot emphasize on accuracy.
• Straight Edge: Think of this as a level’s less flashy cousin. It is used for pinpointing sneaky unevenness. Use it in combination with your level to find those subtle dips and rises.
• Circular Saw: Need to cut plywood or OSB sheathing? This is your go-to. Make sure you’ve got a sharp blade and know your safety protocols.
• Jigsaw: When you need to get fancy with curves or make intricate cuts around pipes or weird angles, the jigsaw is your friend. Control is key here; slow and steady wins the race.
• Drill/Impact Driver: These powerhouses are for driving screws, and driving them fast. An impact driver is especially handy for subfloor screws because it delivers extra torque to sink them in deep.
• Hammer: The trusty hammer. Still useful for tapping things into place, persuading stubborn shims, and general percussive maintenance.
• Wood Chisel: Got a high spot that needs to be evicted? A sharp wood chisel will help you carefully shave it down. Practice makes perfect, so go easy at first.
• Self-Leveling Compound Applicator, Mixing Bucket, Notched Trowel: If you’re going the self-leveling route, these are non-negotiable. The applicator helps you pour precisely, the bucket gives you room to mix, and the notched trowel helps spread the compound evenly.
• Shop Vacuum: Cleanup is NOT optional! Dust and debris will ruin your day (and your floor). A shop vac with a good filter is your best friend for a pristine surface.

Materials: The Building Blocks of a Better Subfloor

• Screws and Subfloor Screws: Don’t skimp on screws!
  • Subfloor screws are specially designed to grip wood tightly and resist squeaking. Use them!
  • Regular screws are fine for some tasks, but for securing the subfloor, go with the pros.
• Wood Shims: These thin wedges of wood are your secret weapon against unevenness. They come in various sizes and can be used to fill gaps, level joists, and generally coax your subfloor into submission.
• Plywood or OSB Sheathing: When you need to patch a hole or replace a damaged section, these are your go-to materials. Plywood is generally more stable and moisture-resistant, while OSB is more cost-effective.
  • Pay attention to the grade and thickness to match your existing subfloor.
• Self-Leveling Compound: This magical potion flows into low spots and creates a perfectly level surface. Choose a type that’s appropriate for your subfloor material and follow the manufacturer’s instructions to the letter.
• Construction Adhesive: Liquid gold for securing shims, filling small gaps, and generally making things stick together. Get a high-quality adhesive that’s compatible with your materials.

Safety First: Don’t Be a Subfloor Repair Statistic!

Okay, folks, listen up! We’re about to dive headfirst into the exciting world of subfloor repair. But before you grab that hammer and start channeling your inner Bob Vila, let’s talk about something super important: keeping your precious self safe. Trust me, a perfectly level floor isn’t worth a trip to the emergency room. Think of safety gear as your superhero costume—it might not be the flashiest, but it’ll save the day (and your body!).

Essential Gear: Your Subfloor Repair Arsenal of Awesomeness

Let’s gear up! Here’s your checklist for staying safe and sound:

• Safety Glasses: Imagine a tiny splinter rocketing towards your eyeball. Not a pretty picture, right? Safety glasses are your personal force field against flying debris. Don’t skip ’em!
• Dust Mask/Respirator: Sanding, cutting, demolition… it all kicks up a ton of dust. And who knows what’s lurking in that old subfloor? A good dust mask or respirator keeps your lungs happy and dust-free.
• Ear Protection: Power tools are loud—like, really loud. Over time, that noise can damage your hearing. Grab some earplugs or earmuffs and protect those precious ears. It’s music to your ears…literally!
• Gloves: Splinters are the enemy! Plus, some repair materials can be irritating to the skin. A good pair of gloves will keep your hands protected and grime-free. Choose a pair that fits well and allows you to grip tools securely.
• Knee Pads: All right, let’s face it: you’re going to be spending a lot of time on your knees. Instead of waking up with creaky joints, invest in some comfy knee pads. Your knees will thank you.

Breathing Easy: Ventilation is Your Friend

Working with adhesives, self-leveling compounds, or any other chemical-y stuff? Make sure you’ve got good ventilation. Open windows, turn on a fan – do whatever it takes to keep the air flowing. Nobody wants to get lightheaded from fumes!

WARNING! Asbestos Alert!

Now, for the serious stuff. If you’re working on an older home, there’s a chance your subfloor might contain asbestos. This is NOT something to mess with! Asbestos is a serious health hazard, and disturbing it can release harmful fibers into the air. If you suspect asbestos, stop work immediately and call a qualified professional for testing and remediation. Don’t risk your health – it’s not worth it!

Addressing High Spots: When Your Subfloor Gets a Little Too Excited

So, you’ve found a high spot on your subfloor? Don’t worry, it’s not trying to win a prize for “Most Elevated.” It just needs a little… encouragement… to come back down to earth. Two main ways to tackle this:

Using a Wood Chisel: Controlled Demolition, Tiny Scale

Think of yourself as a sculptor, but instead of creating beauty, you’re restoring it!

1. Get a good grip: Hold the wood chisel firmly, bevel side down (that’s the angled side, folks).
2. Gentle persuasion: Tap the end of the chisel with a hammer, removing small slivers of wood at a time. Patience is your friend here!
3. Angle is key: Work with the wood grain to avoid splintering.
4. Check your work: Regularly use your straight edge to see if you’re making progress and maintaining a smooth transition.

Sanding: The Finer Things in Smoothing

For smaller high spots, sanding is your weapon of choice.

1. Gear up: Dust mask is a MUST! Safety first, always!
2. Start coarse: Begin with a coarse-grit sandpaper to quickly knock down the high spot.
3. Work your way finer: Gradually switch to finer grits to smooth out the surface and blend it seamlessly with the surrounding area.
4. The art of blending: Feather the edges of the sanded area so there are no abrupt changes in height.

Correcting Low Spots: Filling the Void

Okay, now we’re dealing with the opposite problem. Your subfloor has decided to take a dip. Time to build it back up!

Shimming: The Art of Strategic Placement

Shims are your tiny, tapered heroes!

1. Locate the low ground: Identify the edges of the low spot that needs support.
2. Shimmy in place: Slide shims under the subfloor at the joists until the surface is level with the surrounding area.
3. Adhesive is your pal: Use construction adhesive to secure the shims in place. This prevents future squeaks!
4. Break it off: Score the shims with a utility knife where they extend beyond the joist and snap off the excess.

Patching with Plywood or OSB Sheathing: A More Solid Solution

For larger dips, a patch might be necessary.

1. Measure twice, cut once: Carefully measure the low area and cut a piece of plywood or OSB sheathing to fit snugly inside.
2. Apply adhesive: Spread construction adhesive on the existing subfloor where the patch will sit.
3. Secure the patch: Screw the patch down into the joists using subfloor screws.
4. Smooth the edges: Use wood filler or self-leveling compound to blend the edges of the patch with the surrounding subfloor.

Self-Leveling Compound Application: The Ultimate Leveler

This is like magic… but with cement!

1. Prep the area: Clean the low spot thoroughly and apply a primer.
2. Mix it up!: Follow the manufacturer’s instructions exactly when mixing the compound.
3. Pour and spread: Pour the mixture into the low spot and use a gauge rake to spread it evenly.
4. Patience is a virtue: Let the compound cure completely before moving on to the next step.

Dealing with Squeaks: Silence is Golden!

Squeaks are the telltale sign of movement. Time to stop the noise!

Tightening Loose Subfloor Boards with Subfloor Screws: Screw It!

1. Find the culprit: Locate the exact spot where the squeak is originating.
2. Screw it down: Drive subfloor screws through the loose board and into the joist below.
3. Experiment: Try different screw placements until the squeak disappears.

Shimming to Eliminate Movement: Filling the Gaps

1. Identify the gap: Locate any gaps between the subfloor and the joists.
2. Shimmy, again: Gently tap shims into the gaps until the squeak disappears.
3. Adhesive, again! Secure the shims with construction adhesive.

Replacing Damaged Sections: Operation: Subfloor Rescue

When water damage or rot has taken hold, it’s time for some serious surgery.

Cutting Out and Replacing Rot or Water Damage: Excision Time

1. Assess the damage: Carefully inspect the area to determine the extent of the rot or water damage.
2. Mark it up: Use a circular saw to cut out the damaged section, extending your cuts slightly beyond the visible damage.
3. Clean it up: Remove all the rotted or damaged wood.

Ensuring Proper Support and Secure Attachment: Building Back Better

1. Inspect Joist Make sure joists are not damaged. Sistering joists might be required if the joists has damage.
2. Measure Twice, Cut Once Again: Measure the opening, cut the replacement section, apply construction adhesive, and screw it into place using subfloor screws, ensuring it’s securely attached to the surrounding subfloor and joists.

Addressing Loose Subfloor Boards: Anchoring for Stability

Sometimes, boards just come loose. It happens.

Using Subfloor Screws to Secure the Boards: The Simple Solution

1. Locate the loose board: Identify the boards that are moving or flexing.
2. Screw ’em down: Drive subfloor screws through the loose board and into the joists below, spacing them every 6-8 inches.
3. Countersink: Make sure to countersink the screw heads so they don’t interfere with your finished flooring.

Leveling with Ease: Mastering Self-Leveling Compound

So, you’ve got a subfloor that looks more like the surface of the moon than a smooth foundation for your dream floors? Don’t despair! Self-leveling compound (SLC) is here to save the day. Think of it as the liquid magic that turns bumpy, uneven messes into perfectly smooth canvases. But when is SLC the superhero you need, and how do you wield its power effectively? Let’s dive in!

When Self-Leveling Compound is Your Best Bet

SLC isn’t always the answer, but it’s a fantastic solution when you’re dealing with widespread unevenness, or low spots, or if you need to level a larger area quickly. It’s especially handy when shimming just won’t cut it, or when you’re prepping for tile, engineered wood, or other flooring types that demand a flawlessly level surface. If your subfloor’s got dips and dives that are more than just minor imperfections, SLC might just be your new best friend. However, you would not want to use this if you see any structural damage or issues with the subfloor (such as joist damage).

Prepping for Perfection: Surface Preparation is Key

Before you unleash the liquid leveling goodness, you gotta get the surface ready. This is where elbow grease meets attention to detail.

1. Cleaning: Start by giving your subfloor a thorough cleaning. Think shop vacuum and maybe even a scrub if there’s stubborn dirt or residue. You want a pristine surface for the SLC to bond to.
2. Patching Holes and Cracks: Any significant holes or cracks need to be patched up before you apply the compound. Use a patching compound suitable for concrete or wood, depending on your subfloor. Let it dry completely.
3. Priming is Paramount: Don’t skip the primer! It’s like the secret handshake that ensures the SLC properly bonds to the subfloor. Choose a primer recommended by the SLC manufacturer, and apply it evenly. Let it dry according to the instructions.

Mixing Magic: Achieving the Right Consistency

Mixing SLC is a bit like baking – consistency is everything. Follow the manufacturer’s instructions precisely regarding the water-to-powder ratio. Too much water, and you’ll end up with a weak, runny mess; too little, and it’ll be too thick to spread properly. Use a mixing drill with a paddle attachment for best results. Mix until you achieve a smooth, lump-free consistency similar to pancake batter. Lumps are your enemy!

Application Techniques: Pour, Spread, Conquer!

Now for the fun part! Pour the mixed SLC onto the prepared subfloor, starting in the deepest areas. Use a gauge rake or notched trowel to spread the compound evenly, ensuring it fills all the low spots and creates a smooth, level surface. Work quickly, as SLC can start to set up relatively fast. Don’t overwork it, though; just guide it into place.

Patience is a Virtue: Curing and Drying Times

Once you’ve applied the SLC, resist the urge to walk on it! Curing and drying times vary depending on the product and environmental conditions. Always follow the manufacturer’s instructions for curing time. Usually, it could be a few hours but up to 24–72 hours. Prematurely walking on it could leave depressions and ruin the smooth surface you worked so hard to create. Let it fully cure, then do a final inspection before installing your flooring. Congrats, you are one step closer to your beautiful floor!

Beyond the Basics: Tackling the Tough Stuff in Subfloor Repair

Alright, so you’ve conquered the squeaks and smoothed out the little bumps. You’re feeling pretty good about your subfloor repair skills, right? But what happens when you stumble upon a subfloor situation that’s a bit… more? We’re talking about those issues that make you scratch your head and think, “Okay, this is beyond my weekend warrior skills.” Fear not, intrepid DIYer! This section is your guide to navigating those advanced subfloor scenarios.

Addressing Sagging Floors: When Your Floor Has the Blues

A sagging floor isn’t just an eyesore; it’s a symptom of a deeper problem. Before you start throwing shims at it, let’s diagnose the root cause.

• Understanding the Cause of Sagging: Why is your floor doing the limbo?

  • Structural Issues: The most common culprit is weakened or damaged floor joists. Think of joists as the bones of your floor – if they’re compromised, the whole thing sags. We also have to consider the spacing of these joists as well as the size.
  • Moisture: Water is a wood’s worst enemy. Over time, leaks, humidity, or flooding can cause joists to rot and weaken, leading to that dreaded dip.
  • Foundation Problems: In some cases, a sagging floor can indicate issues with your home’s foundation. If you suspect foundation trouble, call the professionals.
  • Increased Load: Sometimes it isn’t necessarily a structural issue, but an addition that is bearing more weight than the original flooring was ever meant to hold.

• Sistering Joists: Giving Your Joists a Helping Hand

  • Sistering is the process of attaching a new joist alongside the existing, weakened one to provide additional support. It’s like giving your joist a strong, reliable buddy.
  • Selecting Lumber: Use the same size and type of lumber as the existing joist or consult a structural engineer for guidance. Pro-Tip: Always better to overbuild, then underbuild.
  • Applying Construction Adhesive: A generous bead of construction adhesive is applied to the original joist before attaching the sister.
  • Securing with Screws: Using screws, fasten the new joist to the old one, making sure to follow codes. Stagger the spacing to maximize holding power.

Dealing with Significant Water Damage or Rot: SOS, My Subfloor is a Swamp!

Water damage is a serious issue that can compromise the structural integrity of your subfloor. If you catch it early, you might be able to salvage some of the wood. But if the damage is extensive, replacement is your only option.

• Replacing Entire Sections of the Subfloor: Out with the Old, In with the New

  • Cutting and Removing Damaged Panels: Carefully cut out the affected sections of the subfloor, extending your cuts a few inches beyond the visible damage.
  • Framing and Securing New Subfloor Panels: Install new framing as needed to support the edges of the replacement panels. Use construction adhesive and screws to secure the new panels to the framing.
  • Measure Twice, Cut Once: Taking your time with measurements and doing dry fits is vital. Also, be careful when cutting around things such as plumbing or electrical work.

• Ensuring Proper Ventilation and Moisture Control: Preventing Future Problems

  • Identifying and Repairing the Source of the Leak: Find and fix the cause of the water damage. If you don’t, you’ll be right back where you started.
  • Improving Ventilation: Make sure your crawl space or basement has adequate ventilation to prevent moisture buildup. Consider installing vents or a dehumidifier.
  • Sealing the Subfloor: Apply a moisture-resistant sealant to the subfloor to protect it from future water damage.

Taking on advanced subfloor repairs can be daunting, but with the right knowledge and tools, you can tackle even the most challenging projects.

Seamless Transitions: Achieving a Level Surface Across Rooms

Ever tripped over that awkward spot where your beautiful hardwood meets the not-so-beautiful linoleum? Yeah, we’ve all been there! Creating a smooth, seamless transition between different flooring types and rooms is like the secret handshake of expert home improvement. It’s what separates a DIY job from a professional finish. Let’s dive into how to make those transitions so slick, you’ll feel like you’re gliding from room to room!

Navigating the Terrain: Flooring Material Height Differences

So, your plush carpet dreams are crashing into the reality of thin tile? Not to worry! The height difference between flooring materials is a common puzzle. Different flooring materials have different thicknesses, so its important to understand what the standard thickness is for different flooring , resulting in that annoying unevenness. But a level floor is necessary when transitioning between rooms. For example, carpet is usually thicker than laminate flooring. Recognizing this height gap is the first step. Once you know the difference in thickness, you can start thinking about solutions. Luckily, you aren’t alone in this, and there are great solutions available for you to use in your home.

The Magicians of Transition: Strips and Feathering

Time for some flooring magic! Transition strips are your trusty sidekicks here. These come in all shapes, sizes, and materials, like metal, wood, or even rubber. There’s a type for every situation! A transition strip is your friend if your subfloor is unleveled in transitioning areas. They bridge the gap, providing a gentle slope that looks and feels fantastic. Then there’s the feathering compound, the artist’s tool. It’s a cement-like substance you can use to create a gradual slope, smoothing out the height difference. It’s like contouring, but for floors!

Transition Strips: The Quick Fix for Different Floor Heights

• Understanding Transition Strips: Transition strips are designed to cover the gap between two different flooring materials while accommodating slight height variations. They come in various materials, such as wood, metal, and laminate, and are designed to match or complement the flooring.

• Types of Transition Strips:

  • T-Molding: Used for transitioning between two hard-surface floors of the same height.
  • Reducer: Designed to transition from a thicker floor to a thinner floor.
  • End Cap: Used to transition from a hard-surface floor to a softer floor, such as carpet.
  • Threshold: Typically used at doorways to cover the gap where two different floors meet.

• Installation Tips:

  • Measure and Cut: Accurately measure the width of the doorway or transition area and cut the transition strip to the correct length.
  • Adhesive or Fasteners: Depending on the type of transition strip, use construction adhesive or screws to secure it in place. Ensure the strip is firmly attached to the subfloor.
  • Placement: Position the transition strip so it evenly covers the gap between the two floors, creating a smooth and safe transition.

Feathering Compound: Leveling Uneven Floors

• What is Feathering Compound?: Feathering compound, also known as self-leveling compound, is a cement-based mixture used to create a smooth and level surface over uneven subfloors. It’s ideal for correcting minor height differences and creating a seamless transition between rooms.

• Preparing the Surface:

  • Clean: Ensure the subfloor is clean, dry, and free of debris. Vacuum the area thoroughly.
  • Prime: Apply a primer to the subfloor to promote adhesion of the feathering compound.
  • Seal: Seal any gaps or cracks with caulk to prevent the compound from leaking through.

• Mixing and Applying:

  • Mix: Follow the manufacturer’s instructions to mix the feathering compound with water. The mixture should have a smooth, pourable consistency.
  • Pour: Pour the compound onto the subfloor, starting in the deepest area.
  • Spread: Use a trowel to spread the compound evenly across the surface, ensuring it blends smoothly with the existing floor.
  • Cure: Allow the compound to cure according to the manufacturer’s instructions, typically 24-48 hours.

With these tricks up your sleeve, you can tackle those tricky transitions like a pro. Say goodbye to stubbed toes and awkward glances. Hello, seamless, beautiful floors!

Final Touches: Inspection and Preparation for Finished Flooring

Alright, you’ve wrestled with the squeaks, conquered the unevenness, and shown that water damage who’s boss. Now, it’s time to put on your white-glove inspector hat (metaphorically, of course – unless you actually have white gloves). This stage is all about the details, ensuring your subfloor is not just fixed, but ready to receive its beautiful new covering. Think of it like prepping a canvas before a masterpiece – you wouldn’t want a stray glob of paint ruining the Mona Lisa, right? So let’s dive into these last, but crucial, steps.

Double-Checking for Imperfections: No Nook or Cranny Left Behind!

First, we’re going to thoroughly inspect that subfloor. Get down on your hands and knees (knee pads, remember!) and really look at everything. We’re talking about tiny splinters, errant screw heads, or any little bump that might telegraph through your brand-new flooring. Even seemingly insignificant imperfections can cause problems down the line, so it’s best to address them now.

• What to look for: Nail pops, protruding screws, dried adhesive globs, small cracks, loose shims.
• How to address: Hammer down nail pops, drive screws in further, scrape away adhesive, fill cracks with wood filler, and secure any loose shims.

This is your last chance to make sure everything is perfectly smooth and even. Run your hand across the surface; if anything catches your attention, address it. It’s like giving your subfloor a final exam – make sure it passes with flying colors!

Cleaning Time: Farewell Dust Bunnies, Hello Clean Slate

Next up: the big clean! Dust, debris, sawdust— they are the enemy of a good bond between your subfloor and your finished flooring. Grab your shop vacuum (the MVP of any flooring project, let’s be honest) and go to town. Pay special attention to the corners and edges, where dust loves to hide. You might even want to go over the floor a couple of times to be extra thorough.

• Why this matters: A clean surface ensures proper adhesion for underlayment, adhesives, and the flooring itself. Dust can create a barrier that weakens the bond.
• Extra Tip: After vacuuming, use a damp cloth (not soaking wet!) to wipe down the subfloor. This will pick up any remaining fine dust particles. Just make sure it’s completely dry before moving on!

A sparkling clean subfloor is like a fresh start – ready to embrace its destiny as the foundation for fabulous floors.

Ready, Set, Underlayment (or Primer!): The Final Layer of Love

Finally, it’s time to prep the surface for the finished flooring. Depending on the type of flooring you’re installing, this might involve applying a primer or installing an underlayment. A primer is like a pre-game pep talk for your adhesive, helping it stick better to the subfloor. Underlayment, on the other hand, provides a smooth, cushioned surface for your flooring to rest on.

• Primer: If you’re using adhesive-backed flooring, a primer is often recommended. Follow the manufacturer’s instructions for application and drying time.
• Underlayment: Different flooring types require different types of underlayment. Consider factors like sound insulation, moisture resistance, and thickness. Install according to the manufacturer’s instructions.

This final step is crucial for ensuring the long-term performance and comfort of your finished flooring. Do your research, choose the right products, and install them properly – your feet will thank you!

And that’s pretty much it! Leveling a wood subfloor might seem daunting, but with a little patience and the right tools, you can totally DIY this. Get ready to say goodbye to those annoying squeaks and hello to a perfectly flat foundation for your new flooring. Happy leveling!
