Customers often wonder how we are able to do such perfect tiling. Of course, much of the results come from years of practice and dedication. However, there are also some tricks that we use to make sure that each tile is perfectly separated from the next. Naturally, we use spacers between each tile. Spacers are made from a soft material that can deform with the weight of heavy tiles. The photo below shows how we prevent this from happening. The red and yellow pieces are shims made of hard plastic. They support the framework of the tiles until the mortar is dry. The end result is perfect spacing.
The red and yellow pieces are shims, the white pieces are spacers.
