A floor tiling job starts with the existing floor and the proposed tile, not just square metres. Check background suitability, finished height, doors and transitions. If heating is involved, confirm the whole system and installation sequence before choosing the adhesive and finish.
Look below the finish
Tell us whether the current surface is timber, concrete, existing tile or something else. Mention movement, cracks or uneven areas. A tile finish depends on the support beneath it, so preparation must be part of the brief.
The background, tile type and service conditions influence adhesive selection. A product suitable for one substrate is not automatically suitable for another. Ask for a compatible installation specification rather than choosing an adhesive by price alone.
Finished height affects more than the floor
Check the thresholds into adjoining rooms, the clearance beneath doors and the position of appliances. Ask how changes in height will be finished so you can compare the complete job rather than just the tiled area.
If you want a continuous finish between spaces, confirm the direction of the layout and where it should start. A paper sketch with room dimensions is often more useful than separate close-up photographs.
Choose a tile for the use, not only the look
Ask the supplier whether the tile is rated for the intended floor use and conditions. For wet areas, discuss the surface characteristics and cleaning needs. Request the product information rather than assuming every tile shown in a bathroom photograph is suitable.
If underfloor heating is present or planned, include it in the enquiry. The system needs coordinated specification and commissioning. Heating compatibility is more than a claim printed on the tile box.
Questions homeowners ask
Can floor tiles be laid over timber boards?
The floor needs assessment and a suitable supporting build-up. Do not assume direct fixing to existing boards is appropriate. Background movement and the chosen installation system need to be considered.
Will a tiled floor change the height at my doors?
It can. Preparation and the new finish add to the build-up, so check door clearance, thresholds and adjoining finishes during planning.
How long before I can walk on new floor tiles?
Follow the actual adhesive and grout instructions and the agreed installation plan. Product choice, conditions and the type of traffic affect when the floor can be used.
