Bamboo flooring can only be installed over joists if it is at least 18mm in thickness. The flooring can then be secret nailed or secret screwed directly down to the joists. Alternatively, a layer of plywood or chipboard (at least 18mm in thickness) can be laid onto the joists first.
Before installing your bamboo flooring, you must ensure that your subfloor is of a sound quality and is flat, level, dry and clean. For more information about this see our article on preparing your subfloor. Once your subfloor has been checked and tested, you are ready to install your bamboo flooring. You have the choice of secret screwing or secret nailing the bamboo flooring onto the joists.
Secret screwing or secret nailing your bamboo flooring
A 10mm expansion gap must be left around the edge of the room, including doorways, to allow your bamboo flooring to expand and contract naturally. Secure the first row of bamboo flooring by either nailing or screwing into the groove of the planks. There should be a minimum of three nails or screws per plank, and be careful not to go too close to the end of the plank as this may cause it to split. Once the first row is in place and is straight and secure, you can carry on building up the rows using the same method. You can stagger the planks of flooring in whatever way you like.
This article is offering some general advice and guidance, however always recommend that you consult a professional floor fitter who has experience and knowledge of the type of bamboo flooring that you want to install.
