Choosing subfloor for hardwood, tile and laminate floors

Choosing the Right Subfloor for Hardwood, Tile, and Laminate Floors

Choosing the right subfloor for hardwood, tile, and laminate floors is essential for a stable and long-lasting flooring system. Your flooring is only as good as the surface beneath it. A strong, well-built subfloor provides stability, prevents squeaks, and protects your investment for decades. Whether you’re installing hardwood, tile, vinyl, or laminate, the right subfloor material ensures lasting durability and performance.

What Is a Subfloor?

The subfloor is the foundation of your flooring system, the sturdy base that sits directly on the floor joists. Once your finished floor is installed, it remains hidden but plays a critical structural role. According to the National Wood Flooring Association (NWFA), proper subfloor preparation is essential for long-term flooring performance.

Common Subfloor Materials

The two most common subfloor materials are plywood and oriented strand board (OSB).

  • Plywood Subfloor: Usually ½-inch or ¾-inch A/C-graded plywood, with a smooth top surface (“A”) and a rough underside (“C”). It’s known for strength and stability.

  • OSB (Oriented Strand Board): Made from compressed wood flakes bonded with phenolic resin. OSB subfloors are cost-effective, moisture-resistant, and perform comparably to plywood when properly sealed.

Because the subfloor is installed during a home’s original construction, replacing or modifying it later is labor-intensive and costly, so choosing the right material from the start matters.

Subfloor vs. Underlayment: What’s the Difference?

A subfloor supports your entire flooring system, while underlayment is a thin layer between the subfloor and the visible floor finish. Underlayment smooths out minor imperfections, adds cushioning, and reduces sound or moisture transfer.

Common Underlayment Types

1. Cement Board Underlayment

Used beneath tile flooring, cement board strengthens the base and prevents flexing or cracking. It’s ideal for bathrooms, kitchens, or areas with high moisture.

2. Foam or Cork Underlayment

Perfect for laminate floors, foam or cork adds comfort and sound absorption. Because laminate can feel rigid underfoot, this underlayment helps cushion each step while masking slight subfloor imperfections.

3. Plywood Underlayment

When extra height or rigidity is needed, a second layer of plywood may be installed above the subfloor. This “double-plywood system” helps align floor heights between rooms and adds strength for heavy finishes like stone or tile.

Best Subfloor Options by Flooring Type

Subfloor for Hardwood Flooring

For hardwood flooring, ¾-inch A/C-graded plywood is the best choice. It provides a stable, nail-friendly base for both solid and engineered wood flooring.

Pro tip: If you’re upgrading, choose tongue-and-groove plywood to minimize movement and eliminate squeaks.

Subfloor for Laminate Flooring

Laminate can be installed directly over a plywood or OSB subfloor, but older homes may have thinner, uneven boards. To prevent flexing or visible seams:

  • Add a thin plywood layer as a secondary subfloor.

  • Use foam or cork underlayment to smooth out imperfections and absorb noise.

Subfloor for Tile Flooring

Tile floors demand rigidity and zero movement.
An unstable subfloor can lead to grout cracks or tile fractures.

For tile:

  • Start with ¾-inch plywood or OSB subflooring.

  • Add cement board as the underlayment layer for strength and moisture resistance.

  • Inspect joists for rot or weakness before installation.

Concrete Slabs and Subfloor Considerations

Homes built on slabs don’t have a traditional wood subfloor. Instead, the concrete surface acts as both the subfloor and foundation. In these cases:

  • Use vapor barriers to prevent moisture intrusion.

  • For engineered wood or laminate, consider a moisture-resistant underlayment to protect the floor system.

  • Avoid installing solid hardwood directly on concrete without proper preparation.

FAQ: Subfloors & Underlayment

Q: What is the best subfloor for hardwood flooring?

A: A/C-rated plywood, typically ¾-inch thick, provides a stable, nail-friendly base and helps prevent squeaks.

Q: Can laminate flooring go over plywood or OSB?

A: Yes. Install laminate over plywood or OSB with a foam or cork underlayment to smooth minor imperfections and reduce noise.

Q: Do tile floors require cement board?

A: Yes. Cement board over a sturdy plywood or OSB subfloor adds rigidity and moisture resistance, helping prevent cracked grout or tiles.

Q: What’s the difference between a subfloor and an underlayment?

A: The subfloor supports the entire structure; underlayment is a thin layer between subfloor and floor finish that improves comfort, sound control, and moisture protection.

Q: Can I install flooring directly on a concrete slab?

A: Yes, but use a vapor barrier or moisture-resistant underlayment for laminate or laminate to protect against moisture. Engineered Wood can be glued right onto your subfloor using a moisture barrier glue.

Floor care tips for laminate flooring

Floor Care Tips: The Ultimate Guide to Cleaning & Protecting Laminate Floors

Laminate flooring is known for its durability, beauty, and cost-effectiveness—but only when it’s cared for properly. Many homeowners assume laminate is difficult to clean, but with the right floor care tips, you can keep your floors looking brand new for years. The key is understanding what cleaning methods work, what tools to avoid, and how to prevent long-term damage.

If you’ve struggled with streaks, residue, or dulling floors, don’t worry—you’re not alone. Below is the complete guide to caring for your laminate flooring, extending its life and preserving its shine.

Why Laminate Flooring Requires Specific Care

Unlike hardwood, laminate is a layered synthetic floor that contains a photographic surface layer. This means:

  • It cannot be refinished like hardwood.
  • Moisture must be carefully controlled.
  • Abrasive tools can permanently damage the top layer.

With that reality in mind, it’s essential to follow proper cleaning methods—especially the ones recommended below by flooring experts.

Floor Care Tip #1: Don’t Sweep Your Laminate Floor

It seems natural to grab a traditional broom, but when it comes to laminate, a broom is one of the worst tools you can use.

Here’s why:

  • Brooms leave behind fine particles that smear under a wet mop.
  • Loose grit can scratch your laminate’s surface.
  • Stiff broom bristles can create swirl marks.

Instead, flooring experts recommend using a dry dust mop or a microfiber mop. These tools trap dust rather than pushing it around, preventing scratches and streaks.

If you prefer using a vacuum, be sure to:

  • Use the “hard floor” or “bare floor” setting
  • Turn OFF the beater bar
  • Avoid metal wheels that can scuff the surface

Vacuum rollers are notorious for causing tiny scratches. Over time, those scratches can dull your laminate’s protective coating.

Floor Care Tip #2: Use Less Cleaner—Not More

One of the most important floor care tips is understanding the amount of cleaning product you should actually use. Many homeowners believe that more cleaner equals a cleaner floor, but with laminate, the opposite is true.

Using too much cleaner leads to:

  • Product buildup
  • Dull, streaky floors
  • Sticky or hazy residue
  • Premature wear of the top layer

A light misting or a small amount of cleaner is usually more than enough. In fact, for most weekly cleanings, warm water is all you need to remove dust and fresh dirt.

It’s also crucial to choose the right type of cleaner. Some standard household cleaners contain chemicals that damage laminate—particularly ammonia-based products.

Safe Laminate Cleaner Options

  • Cleaners labeled specifically for laminate floors
  • Mild dilutions of white vinegar (only occasionally)
  • Warm water with a microfiber mop

Floor Care Tip #3: Avoid Excess Water

Laminate floors are vulnerable to moisture, which can seep into the seams and cause swelling or lifting. Never use:

  • Wet mops
  • Steam mops
  • Bucket-style string mops

Steam and standing water will cause irreparable damage by weakening the core layers of laminate. Always use a lightly damp microfiber pad and dry any visible moisture immediately.

Floor Care Tip #4: Protect Your Laminate From Scratches

Scratches are one of the most common reasons laminate floors age prematurely. Luckily, preventing them is simple:

  • Add felt pads under all furniture legs.
  • Use rugs in high-traffic areas like hallways and entryways.
  • Trim your pets’ nails regularly.
  • Lift furniture—don’t slide it.

For enhanced protection, especially in mudrooms or kitchens, consider using water-resistant laminates from our Laminate Flooring Supply Collection.

Floor Care Tip #5: Clean Spills Immediately

Even though laminate has a protective surface, spills should never be left sitting. Liquids that seep into seams can cause bubbling or lifting.

Wipe up immediately:

  • Water spots
  • Pet accidents
  • Beverage spills
  • Cleaning solutions

For sticky spills, a damp microfiber cloth works best. Avoid abrasive scrub pads or scouring tools.

Floor Care Tip #6: Avoid Harsh Chemicals

Harsh cleaners may cause the laminate coating to break down or discolor. Do NOT use:

  • Ammonia-based cleaners
  • Pine oil
  • Abrasive powders
  • Bleach
  • Dish soap mixtures

Dish soap can leave streaks; bleach and ammonia can erode the finish. Stick to laminate-safe solutions only.

Floor Care Tip #7: Use the Right Tools

Here are the tools you should always have on hand:

  • Microfiber mop
  • Dry dust mop
  • Spray bottle with laminate-safe cleaner
  • Soft microfiber cloths
  • Laminated-floor-safe vacuum

These tools prevent damage and ensure your cleaning routine is fast and efficient.

Floor Care Tip #8: Perform Routine Deep Cleaning

Weekly cleaning keeps your laminate in great shape, but deep cleaning every 1–2 months helps remove unseen buildup. A deep clean includes:

  • Vacuuming corners and baseboards
  • Spot-cleaning small stains
  • Mopping with warm water and minimal cleaner

If your laminate looks hazy even after cleaning, you may have residue buildup. Using a laminate-safe residue remover can restore shine.

Floor Care Tip #9: Prevent Long-Term Wear

Most long-term laminate damage comes from daily habits, not single events. To protect your flooring:

  • Rotate area rugs every few months.
  • Use mats at each exterior door.
  • Install furniture glides under frequently moved chairs.
  • Place protective mats under rolling office chairs.

These steps drastically slow the wear-and-tear process.

Floor Care Tip #10: Know When It’s Time to Replace

Even well-maintained laminate eventually reaches the end of its life cycle—usually after 15–25 years. If you notice warping, lifting, or deep scratches, it may be time to consider a new installation.

Conclusion

Proper laminate floor maintenance isn’t complicated—it just requires the right knowledge. With these expert floor care tips, you can protect your flooring, avoid costly repairs, and keep your home looking beautiful.
