Tiles are not to be tampered with, however you handle it and for what purpose it serves. Tiles on kitchen and bathroom walls for instance, are one thing but tile flooring in scottsdale az is quite another matter altogether because it is quite susceptible and vulnerable to pressure, whether it be foot traffic or commercial or industrial processes. It might be less vulnerable in the health services sector because after all, all matters arising are generally handled with care.
And can you imagine how it must be down at your local butcher or fish monger. The preparation areas and a portion of the customer services area are generally layered with tiles, both on the walls and the floors. And particularly in this day and age, right in the middle of a global pandemic, it remains essential that all tiles be washed down thoroughly not just once a day but several times a day. And of course, these tiles must still be properly sanitized.
Especially so in the public restrooms, favorite resting places for all manner of germs and diseases. In any case, tile bakers and tilers are now able to manufacture tiles specially prepared in such environments where the utmost sanitization is required. Good and well to be the neighborhood spokesman for outstanding DIY work but do be careful how you go about layering your tiles on both walls and floors.
It is a generally accepted practice to start tiling from the center of the floor space or wall as the case may be. Also note that correct spacing between each tile still needs to be factored in. This is critically important given that tiles are quite responsive to fluctuating room temperatures in which case tiles tend to expand and contract.
