Timber flooring may be either plywood sheets or tongue and groove flooring. These may be tiled over using Bostik Asaflex.
Bostik Multiprime may be used as a primer, though Bostik PrimeGrip Non-porous may be required for more dense timber species.
Before tiling over timber, it is advisable to contact the timber manufacturer for advice regarding the required preparation. Not all timbers can have tiles bonded directly to them. The density and oil content of the timber will have a bearing on how successful the installation would be. If in doubt, it is best to install a suitable ceramic tile underlay over the timber prior to tiling.
Any butt joint in the timber should be well supported to minimize any risk of cracking tiles due to movement between sheets or boards.
This advice is intended to be general only. In addition, it is assumed that the tiles and / or materials tested were representative of the materials to be installed.
Contact Bostik for advice before work commences if the nature of the tile changes, or if intending to install in unusual situations.
