The preparation work that needs to occur to make a site ready to receive a mosaic will vary depending on the site conditions.
WALLS Generally speaking wall mosaics are fixed to a sand and cement rendered wall. Walls must be sound and dry, any structural or damp problems must be repaired first. Newly rendered walls must be left to dry before mosaic fixing commences.
Left you can see a brick wall where the brick has been cut back and then rendered to give a flush finish to the mosaic which is just being fixed.
FLOORS Floor mosaics require careful preparation. Usually the mosaic is fixed to a specially laid sand cement screed of suitable thickness for the expected traffic. These screeds have to be of good quality, flat, including required falls for water run off and finished to the right level for the mosaic, usually only 5mm below the finished surface level. The correct drying of floor screeds can take many weeks so the preparation of a site for a floor mosaic need to be well planned.

Whatever your site requires I am on hand to assist and advise on the best solution for your site including substrate specification and liaison with site contractors. This advise can also incorporate associated works such as lighting, benches and so on.
Aluminium Honeycomb Board - Made from high quality aluminium honeycomb these panels originated in the aircraft industry and are extremely light and strong enabling the mosaic to be hung like a picture.
Foam Core Cement Board - These light weight boards can be mechanically fixed to a wall to provide an isolated substrate for fixing the mosaic to.
Glass Fibre Cement Structures - Glass fibre reinforced cement makes an excellent surface for mosaic fixing for sculptural forms.
Paving Slabs Stone and concrete paving slabs can be used as bases for mosaic
Steel Trays - Lightweight concrete filled trays can be used to create larger slabs for particular floor projects whilst mosaic can also be fixed to steel forms using epoxy and flint liner.
Left can be seen the use of steel tray slabs to create a cracked, trompe L'oeil effect for the Roman garden at the RHS Chelsea Flower Show.
Stone Sculpture Stone itself makes an excellent substrate for fixing mosaic two, in the illustration here a standing stone is carved ready to receive mosaic inlay.
Site preparation usually takes place whilst the mosaic construction is underway, once both are ready the installation can begin.
