If you’re ever looking at ceramic or porcelain tile, chances are pretty good that you are going to run in the term “rectified” at some point. So what is rectified tile, and why should it matter to you?

What is rectified tile?

Simply put rectified tiles have been been ground and machined in order to give them straight edges – which in turn gives them exact, uniform dimensions.

Why would I want rectified tile?

The uniform edges on rectified tile allow you to use the thinnest of grout lines (3mm and under), giving the tiled surface an almost seamless appearance.

What else should I know about rectified tile?

Rectified tiles are also sometimes referred to as “sharp edge” tiles because of the sharp edges that result do to the edge finishing. It is important to consider how the tiles will be used as the sharp edges of rectified tiles can chip.

Rectified tiles have a more involved production process they do cost more than conventional non-rectified tiles. If you are looking for sleek, clean, symmetrical appearance the extra cost may be worth it to you.

Some rectified tiles are large. Keep in mind the larger the tile the more critical is is that the substrate underneath is flat.

Because of all of the work that goes into finishing rectified tiles it is very unusual to find tiles smaller than 300mm by 300mm.
