How to Lay Chipboard Flooring

When coarse sawdust is mixed with resin, it produces chipboard flooring, also known as oriented strand board.

Chipboard can be used as a main floor or subfloor.Chipboard can be used as a main floor or subfloor.
Chipboard is less expensive than other materials. It also makes a good subfloor for all types of flooring such as tile, slate, carpet and vinyl. Whether you're laying chipboard as a subfloor or a primary floor, the procedure is the same and relatively simple.

Measure the area of the room, using a tape measure. Divide the area by the size of the chipboard plank to calculate how many sheets you'll need.

Make a mark on the wall above every joist with a marker. This will help you know where the joists are when you're nailing down the board.

Lay out the chipboard over the floor. Use the color-coded PVC tongues on the edges of the boards to fit the boards together.

Nail down the chipboard with a hammer and 2-inch ribbed nails.

Fill in corners and edges with the remaining sheets of chipboard. Measure the size of the corner or edge you need to fill, cut a piece of the sheet to the same dimensions with an electric saw, and nail the piece down.

Things You Will Need

  • Measuring tape
  • Hammer
  • 2-inch ribbed nails
  • Electric saw
  • Pencil


  • Choose the type of chipboard you want. Chipboard comes in three densities: high, medium and low. High-density chipboard is best for subflooring.
  • If you live in a damp climate or area, buy chipboard pretreated for termites and fungus.


  • Chipboard floors are very squeaky.
  • Low-density chipboard can damage easily when waterlogged.
  • If you are laying chipboard as a subfloor, check the building codes to find out the required thickness.
  • Wear safety glasses when operating a saw.
