Bamboo flooring is very versatile and can be installed on almost any sub-floor. Bamboo flooring can be either glued down to concrete or screed, or floated over an underlay.
Before you start to install your bamboo flooring, you must ensure your sub-floor is flat, level, dry and clean. For more information about this see our article on preparing your sub-floor. Once your sub-floor has been checked, you can now install your bamboo flooring. You have the choice of either gluing your floor down directly to the concrete or floating it over an underlay.
Gluing your bamboo floor over concrete
Sweep and clean the surface of the concrete to ensure it is level and clean. You must leave a 10mm expansion gap around the perimeter of the room (including doorways), to allow the bamboo to naturally expand and contract. Now glue the first plank of flooring directly down to the concrete, using a flexible flooring adhesive, such as Sika T54. Once the first row is straight and secure, continue with the rest of the flooring. If you are using bamboo flooring with a click fitting system then just glue the planks to the concrete as you click them into place. If you are using bamboo flooring with a tongue and groove profile, then you just fit the tongue and grooves together and glue the planks to the concrete subfloor. The planks can be staggered in whatever pattern you choose.
Floating your bamboo floor over an underlay
Once you have laid your underlay, for example Silver Bam Underlay, remember to leave a 10mm expansion gap around the perimeter of your room, including doorways. You can use 10mm spacers to do this if you wish. This will give the bamboo flooring room to naturally expand and contract. If you are using bamboo flooring with a click fitting system, then simply click and lock the boards into place, loosely laid over the underlay. If you are using bamboo flooring with a tongue and groove profile then glue the tongue and groove joints together with a WPVA that conforms to EN204: D3. Do not glue the flooring to the underlay; it should be loosely laid over the top. Stagger the planks in whichever way you prefer.
These are just some simple guidelines and we always advise that you consult a professional floor fitter who has experience and knowledge of the type of floor that you wish to install.
