CTEF Blog - About Tile Education and Installer Certification

How often are you including tile edge protection in your tile assembly specifications? Although not required for all installations, edge protection absolutely provides better results.

Ultimately, if you're serious about delivering only high-quality installations of ceramic, porcelain, and stone tile, you must have the hand-skills to put the entire tile assembly into place along with the knowledge of what products are available to finish the project successfully.

Thinking about protecting tile edges is a perfect example. 

Glass tile has truly captured the hearts of consumers in both the residential and commercial marketplaces, making it important for tile installers to understand how to avoid trowel ridges and marks that are visible through translucent glass tile.

Do you know the proper technique?

Perhaps it seems self-evident that the tile patterns you select need to be balanced when installed. And yet, simply based on photos readily available, balance and common sense don't always go hand-in-hand.

Especially when your tile choices come in so many more sizes, shapes, patterns, and colors than in the past.  Along with this availability comes creativity with endless possibilities.

Today we will focus on one of these options – the pattern.  Combining these tiles, whether square or rectangular, with an offset pattern creates a unique visual many times not realized in its square or stacked design.

If you think that warped tile isn't acceptable, we're here to help you understand what is and what isn't acceptable. You see, there are two categories to consider: inherent (actual) warpage and excessive warpage.

Actual warpage is a function of the tile manufacturing process. It's something qualified tile installers and Certified Tile Installers take into consideration.

Excessive warpage may indicate a bigger issue.
