OSB (Oriented Strand Board) is a popular choice for flooring due to its strength, affordability, and ease of installation. Whether you're renovating your home, building an extension, or installing a subfloor, OSB board flooring offers a durable and reliable solution. In this step-by-step guide, we'll walk you through the process of installing OSB board flooring, helping UK homeowners achieve professional-quality results with minimal fuss.

Why Choose OSB Board Flooring?

OSB board flooring is an excellent choice for subfloors and can also be used as a finished flooring surface in certain areas. Its robust construction makes it ideal for supporting heavy loads, and it's more cost-effective compared to alternatives like plywood. It's also compatible with other flooring options, such as vinyl, carpet, or tile, which makes it versatile for any project.

Moreover, flooring chipboard is another affordable option for subflooring, offering similar benefits, though OSB boards are slightly stronger and more durable for high-traffic areas.

As a trusted supplier of building materials, Builders Merchant provides high-quality OSB boards and other essential materials for all your flooring projects.

Materials and Tools You'll Need

Before you begin, ensure you have the following materials and tools:

  • OSB boards (ensure they are the correct thickness for your flooring needs)
  • Measuring tape and pencil
  • Circular saw (or hand saw)
  • Drill and screws
  • Power sander or sanding block
  • Flooring adhesive (if needed)
  • Safety gloves and goggles

Step 1: Prepare the Subfloor

Ensure the subfloor is clean, dry, and level. Any unevenness can lead to issues with your flooring later on. If the existing floor is damaged or uneven, consider leveling it with a thin layer of flooring chipboard or plywood.

Step 2: Measure and Cut the OSB Boards

Use your measuring tape to determine the dimensions of the room and calculate how many OSB boards you'll need. Once you have the measurements, cut the boards to fit using a circular saw. Be sure to leave a small expansion gap (around 10mm) along the edges of the floor to allow for natural expansion and contraction due to temperature and humidity changes.

Step 3: Lay the OSB Boards

Start laying the OSB boards at one corner of the room, making sure the smooth side is facing up. If you're installing the boards as a subfloor, lay them perpendicular to the joists to maximize strength. Stagger the seams between the boards to reduce the chances of them becoming unstable.

Step 4: Secure the OSB Boards

Once the boards are in position, secure them to the subfloor using screws. Start from the center of the board and work your way out, leaving a small gap from the edges to allow for expansion. Be sure to drive the screws deep enough so they don't protrude from the surface of the OSB.

Step 5: Sand and Finish the Surface

After all the boards are secured, lightly sand the surface to remove any rough patches. This step is particularly important if you plan to finish the OSB boards with a sealant or paint. If you're using the OSB board as a finished flooring surface, you may want to apply a clear polyurethane coating for added protection against wear and tear.

Step 6: Install the Final Flooring (If Applicable)

If you're using OSB board flooring as a base for other flooring types, such as carpet, tile, or laminate, install these materials according to their specific guidelines.

Step 7: Final Touches

Once your OSB board flooring is installed, check for any gaps or uneven areas and address them accordingly. You can install trim around the edges of the room for a polished finish.
