Hey everyone, and welcome back to my channel! Today, I’m going to be showing you how to install plywood on a wood floor. This is a great way to level out your floor and create a smooth surface for new flooring, such as tile, hardwood, or laminate.
In this video, I’ll walk you through the entire process step-by-step, from gathering the necessary tools and materials to laying the plywood and securing it in place. I’ll also cover some important tips and tricks to help you avoid common mistakes.
So, whether you’re a DIY enthusiast or a complete beginner, this video is for you. Let’s get started!
Laying plywood on a wood floor offers several advantages:
- Strengthens the subfloor: Plywood adds rigidity and stability to the existing floor, preventing it from sagging or flexing.
- Provides a smooth surface: Plywood creates a level and even surface for installing final flooring materials like tile, vinyl, or laminate.
- Improves soundproofing: Plywood acts as a sound barrier, reducing noise transmission between floors.
- Increases thermal insulation: Plywood adds an extra layer of insulation, making the room more energy-efficient.
- Versatile and cost-effective: Plywood is readily available, relatively inexpensive, and can be easily cut and installed.
Both plywood and OSB (oriented strand board) are commonly used for subflooring. Here’s a comparison:
Plywood:
- Pros: Stronger, more stable, smoother surface, better soundproofing, more resistant to moisture.
- Cons: More expensive than OSB.
OSB:
- Pros: Less expensive than plywood, easier to cut.
- Cons: Less strong and stable, rougher surface, less soundproofing, more susceptible to moisture.
To lay plywood on a wood floor, you’ll need the following:
- Plywood: Choose the appropriate thickness and grade for your project.
- Underlayment: Optional, but recommended for added soundproofing and moisture protection.
- Screws or nails: Choose the appropriate size and type for your plywood and subfloor.
- Circular saw or jigsaw: For cutting the plywood.
- Drill: For pre-drilling holes for screws.
- Hammer: For driving nails.
- Level: To ensure the plywood is laid evenly.
- Chalk line: For marking straight lines.
- Safety glasses and gloves: For protection.
- Prepare the subfloor: Ensure the subfloor is clean, dry, and free of debris. Repair any damaged areas.
- Cut the plywood: Measure and cut the plywood sheets to fit the room, leaving a 1/4-inch expansion gap around the perimeter.
- Install underlayment (optional): If using underlayment, lay it down over the subfloor, following the manufacturer’s instructions.
- Lay the plywood: Start laying the plywood sheets in a staggered pattern, with the long edges perpendicular to the floor joists.
- Secure the plywood: Use screws or nails to secure the plywood to the subfloor. Pre-drill holes for screws to prevent splitting.
- Fill gaps and sand: Fill any gaps between the plywood sheets with wood filler and sand the surface smooth.
- Install final flooring: Once the plywood is laid and prepped, you can install your final flooring material.
- Wear safety glasses and gloves when working with plywood.
- Use a chalk line to mark straight lines for cutting the plywood.
- Stagger the plywood sheets to create a stronger subfloor.
- Pre-drill holes for screws to prevent splitting the plywood.
- Leave an expansion gap around the perimeter of the room to allow for wood movement.
- Ensure the plywood is level before installing final flooring.
By following these instructions and tips, you can successfully lay plywood on a wood floor and create a strong, smooth, and level surface for your new flooring.
Before laying plywood, it’s crucial to assess the condition of your existing wood floor. Look for any signs of damage, rot, or unevenness. If significant issues are present, addressing them first is essential. Minor imperfections can be dealt with during the plywood installation process.

Ensure you have all the necessary tools and materials before starting. This includes:
- Plywood sheets (choose the appropriate thickness and grade for your needs)
- Circular saw or jigsaw for cutting plywood
- Power drill and appropriate screws or nails
- Level
- Chalk line or straightedge
- Spacers
- Safety equipment (goggles, gloves, dust mask)
If your subfloor has minor dips or unevenness, shims can be used to create a level surface for the plywood. Place shims strategically beneath the plywood sheets, adjusting their thickness as needed to achieve a level plane.
For more significant unevenness, self-leveling compound can be poured onto the subfloor. This compound will flow and self-level, creating a smooth and even base for the plywood. Follow the manufacturer’s instructions for mixing and applying the compound.
Plan the layout of the plywood sheets to minimize waste and ensure proper coverage. Start by measuring the area and determining the number of sheets needed. Consider staggering the seams of the plywood sheets for added strength.
Use a circular saw or jigsaw to cut the plywood sheets to the desired size. Ensure your cuts are accurate and clean.
Lay the plywood sheets onto the prepared subfloor, aligning them according to your planned layout. Use spacers to maintain consistent gaps between the sheets for expansion and contraction. Secure the plywood to the subfloor using screws or nails, ensuring they are driven straight and flush with the surface.
- Always wear safety equipment when working with power tools.
- Choose the right type of plywood for your project, considering factors like thickness, grade, and moisture resistance.
- Ensure the subfloor is clean, dry, and free of debris before laying the plywood.
- Use a level frequently to check for evenness throughout the installation process.
- Stagger the seams of the plywood sheets for added strength and stability.
- Allow the plywood to acclimate to the room temperature and humidity for at least 24 hours before installation.
- Consider seeking professional help if you are unsure about any aspect of the installation process.
By following these steps and expert advice, you can successfully lay plywood on your wood floor, creating a smooth, level, and stable base for your flooring project.
