Here are the general steps to install bamboo flooring over plywood:
Prepare the subfloor: Make sure the plywood subfloor is clean, dry, level, and free of any debris or protruding nails. If necessary, sand down any high spots or fill in low spots with a leveling compound.
Acclimate the bamboo flooring: Bring the bamboo flooring planks into the room where they will be installed and let them acclimate for at least 48 hours. This will allow the planks to adjust to the room’s temperature and humidity.
Install the underlayment: Install a suitable underlayment over the plywood subfloor to provide a moisture barrier, sound insulation, and cushioning. A popular choice is a 15 lb. felt paper or a high-quality foam underlayment.
Measure and plan the layout: Measure the room and plan the layout of the bamboo flooring planks, keeping in mind any doorways, corners, or obstacles. It is recommended to start the installation from the longest wall in the room.
Install the first row: Start by laying the first row of bamboo flooring planks along the longest wall, leaving a 1/2-inch expansion gap between the planks and the wall. Use a pneumatic flooring nailer or stapler to secure the planks to the subfloor, making sure to nail or staple each plank at a 45-degree angle.
Continue with the remaining rows: Continue installing the bamboo flooring planks row by row, making sure to stagger the joints and maintain the expansion gap. Use a pull bar and tapping block to snugly fit the planks together.
Cut and fit the last row: Measure and cut the last row of bamboo flooring planks to fit against the opposite wall, leaving a 1/2-inch expansion gap. Use a table saw or circular saw to cut the planks to size.
Install the trim and transitions: Install baseboards, quarter rounds, and transition pieces to cover the expansion gap and provide a finished look.
Overall, installing bamboo flooring over plywood is similar to installing any other type of hardwood flooring. It requires careful planning, proper subfloor preparation, and precise installation techniques.
