How to Lay Plywood Flooring Simply and Effectively
If you’re seeking an affordable, durable, and stylish flooring solution, plywood flooring is an excellent choice. This budget-friendly option provides a simple DIY project that can enhance the look of your space.
In this guide, I’ll provide you with everything you need to know about how to lay plywood flooring, from selecting the right materials to step-by-step instructions.
It doesn’t matter if you’re a beginner or have some DIY experience; you’ll find all the tools and techniques you need to succeed. Let’s get into it.
Choosing the Right Plywood for Your Floor
When selecting plywood for flooring, choose the right type for durability and appearance.
Hardwood plywood is strong and ideal for high-traffic areas, while softwood plywood may not hold up as well.
For moisture-prone areas like bathrooms or kitchens, moisture-resistant plywood (marine plywood) is a good choice. Typically, ¾-inch plywood is recommended for its strength and stability.
For a smooth finish, consider using cabinet-grade plywood with fewer knots. In contrast, rough-cut plywood provides a rustic look but requires additional finishing. The proper plywood provides durability and avoids issues like warping or cracking.
Tools Required to Lay Plywood Flooring
Here’s a quick look at the tools you’ll need to successfully lay plywood flooring:
- Compressor and Gun (Pneumatic): To fire pins into the floor at an angle for a secure fit.
- Concave Blade: For cutting thin timber (less than 6mm thick).
- Skin Saw (for thicker timber): For cutting thicker planks (greater than 6mm).
- Tape Measure: To measure and ensure planks fit correctly and are staggered.
- Marker: For marking the lines where cuts are to be made.
- Feather Finish: To level out uneven surfaces or cover small gaps in the floor.
- Ruler or Square: To ensure the boards are correctly aligned (square) for a perfect fit.
- Vacuum or Cleaning Tools: To clean the surface and ensure no debris gets under the floorboards.
How to Lay Plywood Flooring: Step-By-Step Process
Follow this step-by-step guide to learn how to lay plywood flooring, from preparing the boards to securing them for a smooth, durable finish.
Step 1: Preparing the Boards
Before starting the plywood installation, it’s crucial to prepare the boards properly. Always lay the plywood in the opposite direction of the existing floorboards to create a stronger bond with the subfloor.
This technique makes sure the plywood adheres better and prevents shifting or creaking over time. To check for squareness, lay the first board on top of the next one. This alignment will help you avoid misaligned edges and get a uniform layout.
Proper alignment makes it easier to cut and provides a neat finish throughout the installation process.
Step 2: Cutting the Plywood
Once your boards are ready, the next step is cutting them to fit the space. When you reach walls or skirting boards, use a concave blade to cut around them carefully.
A concave blade provides smooth, precise cuts around obstacles, ensuring the plywood fits snugly against the edges. For uniformity, place one board on top of another to use as a template. This method helps create perfectly square cuts and makes sure the boards fit together with no gaps.
Always measure carefully before making side cuts to guarantee a tight fit against walls, leaving no unfinished or uneven areas.
Step 3: Staggering the Seams
Staggering the seams of your plywood sheets is crucial for both its look and structural integrity. When the seams are staggered, the boards form a stronger, more stable floor, much like bricks in a wall.
The staggered pattern helps distribute the weight evenly, preventing the floor from shifting or squeaking.
Avoid placing new boards directly over the joints of the plywood beneath; this provides a stronger bond between each piece, reducing the risk of unevenness and future movement. Keeping the seams off the joints is a key step for providing a solid and durable plywood floor.
Step 4: Securing the Plywood
Once the plywood is in place and aligned, it’s time to secure it to the subfloor using a compressor and pinning gun. Drive small pins into the plywood at an angle to fasten it firmly.
The pin’s small coils grip the plywood, preventing any movement. This method provides a strong connection between the plywood and the subfloor, helping to avoid creaking or shifting over time.
As you pin down the boards, keep the surface free from debris. Even small particles can cause bumps and irregularities, so make sure the plywood sits flush and smooth to get the best results.
Step 5: Final Touches and Adjustments
After securing the plywood, inspect the boards for any necessary adjustments. Walk around the room and check that the boards fit tightly against the walls and each other. A tight fit is essential to prevent gaps that would give the floor an unfinished appearance.
If there are any irregular shapes or contours, cut the plywood to follow these lines, ensuring the boards fit seamlessly.
Take the time to clean as you go, removing any dust, dirt, or debris that may have accumulated under the boards. This makes sure the plywood sits well flush against the subfloor, preventing future issues such as squeaks.

Tips and Tricks for a Professional Finish
To make sure your plywood flooring project turns out even better, here are some additional tips:
- Use Underlayment for a Smoother Surface: For a smoother finish, consider adding an underlayment between the subfloor and plywood. This can help fill in any minor imperfections and create a more even surface.
- Go Slow and Be Precise: Take your time to measure and cut each piece carefully. The more precise your cuts, the better the overall look of your floor will be.
- Pre-Drill Holes: If you’re using screws instead of nails, pre-drill the holes to avoid splitting the plywood.
- Staggering Isn’t Just for the Seams: When securing the plywood, make sure to stagger the fasteners as well. This helps prevent weak spots and makes sure the floor is securely held in place across its entire surface.
Maintaining Your Plywood Floor
Once your plywood floor is installed, regular cleaning is essential to help it last. Sweep or vacuum often to remove dust and debris.
For deeper cleaning, use a soft mop with water or a mild cleaner, but avoid soaking the plywood as excessive water can cause warping. Over time, the finish may wear down, making it look dull or scratched.
When this happens, lightly sand the surface and apply a fresh coat of polyurethane to restore shine and protection. Use felt pads under furniture and heavy items to prevent scratches.
Always lift furniture instead of dragging it to avoid gouging the surface. Since plywood is wood, it can be affected by changes in humidity.
Maintain stable humidity to prevent warping or cracking. In high-moisture areas, like bathrooms or basements, ensure the plywood is sealed properly for protection.
Common Mistakes to Avoid
Avoid these common mistakes to ensure your plywood flooring project goes smoothly and lasts for years to come:
- Not Leaving Expansion Gaps: Always leave a 1/8-inch gap between plywood sheets to allow for expansion and prevent warping.
- Cutting Errors: Measure carefully and use a straight edge or a chalk line to make sure accurate and clean cuts are made.
- Incorrect Fastener Placement: Space screws or nails every 6-12 inches along the edges and at least 12 inches in the center.
- Overlooking Subfloor Issues: Make sure the subfloor is clean, level, and free of debris before laying plywood.
How to Deal with Uneven Floors
To prepare for laying your plywood, it’s important to address uneven surfaces. For minor bumps or dips, use a leveling compound to fill in low spots and create a smooth surface.
If the subfloor is significantly uneven, applying a ¼-inch plywood underlayment can help even things out while also adding stability. For any raised areas, a floor sander can be used to smooth them down.
For deeper low spots, shims can help raise the subfloor to the desired level. A level surface is essential to prevent issues like sagging or creaking, ensuring your plywood flooring stays secure and looks great.
Conclusion
Plywood flooring offers a cost-effective, durable, and stylish option for your home. It’s easy to install, and with the right materials and techniques, you can create a beautiful floor that lasts.
Remember, proper preparation, including leveling the subfloor and choosing the right plywood, is key. After installation, maintaining your plywood floor is simple, with regular cleaning and reapplication of the finish as needed.
