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
- 2-inch ribbed nails
- Electric saw
- 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.
