You’ve decided to upgrade your floors, and laminate flooring seems like the perfect choice—durable, stylish, and budget-friendly. But what about the existing subfloor? Can you go ahead and lay down laminate flooring directly on top of your plywood subfloor? The answer, thankfully, is a resounding yes, for the most part. However, there are a few crucial considerations to ensure a smooth, stable, and long-lasting floor installation.

This guide delves into the intricacies of laying laminate flooring over plywood, exploring the underlying factors that influence its success. We’ll cover everything from assessing the condition and sturdiness of your existing subfloor to understanding the proper preparation techniques. By the time you’re done reading, you’ll have the knowledge and confidence to make informed decisions about your flooring project, whether you’re a seasoned DIYer or a first-time home renovator.
Understanding the Importance of Subfloor
The subfloor forms the foundation upon which your flooring rests, and its quality directly impacts the longevity and stability of your final floor. A sturdy subfloor is essential for resisting movement, preventing squeaks, and ensuring a smooth and even surface for the laminate planks. Plywood, with its strength, durability, and ease of installation, is a popular choice for subfloors throughout homes.
When Can You Lay Laminate Flooring Over Plywood?
Generally, you can lay laminate flooring directly over plywood subfloors if they meet the following criteria:
- Stability: The plywood subfloor should be solid, without any noticeable flex or movement.
- Levelness: A level subfloor is crucial for a smooth laminate installation.
- Moisture Control: Ensure the plywood subfloor is adequately protected from moisture. Any moisture penetration could lead to warping, buckling, or mold growth under your laminate planks.
- Thickness: While the ideal plywood thickness for laminate flooring is 3/4 inch, 1/2 inch plywood can suffice for areas with minimal foot traffic.
Assessing Your Plywood Subfloor
Before you dive into the installation, it’s essential to assess the condition of your existing plywood subfloor. Here’s a step-by-step guide:

1. Visual Inspection
Begin with a thorough visual inspection of the plywood subfloor. Check for any signs of:
- Sagging or bowing: A sign of weakened support or underlying structural issues.
- Cracking or splitting: May indicate damage or improper installation.
- Gaps or unevenness: Indicates potential instability and a need for leveling.
- Water damage: Inspect for any signs of moisture penetration, which can lead to warping, buckling, and mold growth.
2. Measuring for Levelness
Use a level to check the flatness of the plywood subfloor. Hold the level against the surface in multiple directions. Ideal levels range between 1/8 inch to 1/4 inch for every 10 feet. If you have significant unevenness, it’s advisable to address it before proceeding with the laminate installation.
3. Load Test
If you suspect any structural weaknesses, perform a simple load test. Stand on the suspected area and gently bounce. If you feel any movement or instability, it signals the need for additional support or repairs before laying laminate flooring.
Preparing the Plywood Subfloor
Once you’ve assessed and addressed any issues, it’s time to prepare your plywood subfloor for laminate flooring. This involves:
1. Clean and Dry
Thoroughly clean the plywood subfloor using a dust mop and vacuum cleaner. It’s essential to remove any debris, dust, or loose particles that could interfere with the installation. Allow the surface to dry completely before proceeding.
2. Addressing Unevenness
If you discovered unevenness during your inspection, there are various methods for leveling the subfloor:
- Shims: Use thin pieces of wood or shims to fill in small gaps and create a smoother surface.
- Self-leveling compound: Apply a self-leveling compound to fill in larger gaps and create a flat surface.
- Plywood patching: Replace damaged or deteriorated sections of plywood with new plywood patches.
3. Moisture Barrier
While plywood is generally resistant to moisture, it’s prudent to install a moisture barrier over the subfloor to further protect your laminate flooring. A plastic sheet or a moisture-resistant underlayment can effectively prevent any moisture from reaching your flooring.
Choosing the Right Underlayment for Laminate Flooring
Underlayment is an essential component of a laminate floor installation, acting as a cushion and providing additional protection against moisture and sound transmission. It’s a critical element that enhances the comfort and durability of your laminate flooring.
There are various types of underlayment available, each with its unique benefits:
- Foam Underlayment: A popular and cost-effective option known for its cushioning and sound absorption capabilities.
- Cork Underlayment: Offers excellent moisture resistance, cushioning, and sound insulation.
- Rubberized Underlayment: Designed for high-traffic areas, providing superior sound absorption and durability.
- Felt Underlayment: Offers cushioning and sound absorption, although it may be less effective against moisture.
Laying Laminate Flooring Over Plywood
With your plywood subfloor prepped and ready, you can begin laying your laminate flooring. Here’s a step-by-step guide:
1. Measuring and Planning
Measure the room accurately to determine the exact amount of laminate flooring required. Consider purchasing a 10-15% overage to account for cuts, waste, and future repairs. Plan the layout of your flooring, starting from the most prominent or visible area of the room.
2. Installing the First Row
Start laying your laminate flooring on the longest wall of the room. Use a spacing tool to ensure evenly spaced gaps between the planks. Secure the first row to the wall with a combination of adhesive and tapping the planks into place.
3. Locking Mechanisms
Laminate flooring typically utilizes a click-lock or drop-lock system, allowing you to easily connect the planks without the need for nails or glue. Follow the manufacturer’s instructions to ensure proper installation and avoid potential problems with the interlocking mechanism.
4. Cutting for Corners and Walls
Use a straight edge and a utility knife to cut the laminate planks to fit around corners, obstacles, and wall edges. Ensure tight fits to create a seamless and professional look.
5. Installing the Last Row
To install the final row, you may need to make precise cuts to fit the remaining space. Use a tape measure and a pencil to mark the cutting line and cautiously use a utility knife or a laminate flooring saw to cut the planks.
6. Finishing Touches
Once you’ve installed all the planks, add transition strips to cover gaps between different flooring types or different levels. Trim any excess underlayment and finish the look with baseboards and mouldings.
Maintenance Tips for Laminate Flooring
Maintaining your newly installed laminate flooring is critical for extending its longevity and keeping it looking its best. Follow these simple tips:
- Sweep or vacuum regularly: Remove dust, dirt, or debris that could scratch the surface.
- Damp mop when necessary: Use a mild cleaning solution and a slightly damp mop for occasional cleaning.
- Avoid harsh chemicals: Avoid using abrasive cleaners or any strong chemicals that could damage the laminate surface.
- Protect from scratches: Place furniture pads or felt protectors under furniture legs to prevent scratches and dents.
