CTEF Blog - About Tile Education and Installer Certification

Yes, credit card joints - as in grout joints the thickness of a credit card - are popular, but given tile industry standards, they aren't possible, appropriate, or even recommended.

Many installers have had customers who have seen tile installations in a magazine or brochure which is exactly what they want in their homes. Unfortunately, the “look” they want to achieve with credit card thickness grout joints most likely will not be possible using the tile that has been selected.

Let's explore why.

Are you ready to take the CTI Hands-on Test at TISE24? If yes, you are in for a treat thanks to TEC!

Do You Know About the '100 in 100'?

It's a wonderful program that the Floor Covering Education Foundation recently announced. If you're new to tile installation, you can benefit from it.

You'll find details below, including CTEF training programs that are eligible.

Do you back butter your tile?

Back buttering tile is a highly opinionated and widely debated topic among tile installers. Although it's recommended for natural stone tile, it's not always necessary or required to get adequate mortar coverage on ceramic and porcelain tile. So, how important is it?

To begin this discussion, we first need to define several words.  According to the NTCA Reference Manual:

If you've been installing tile for a while, you've certainly encountered situations where you were asked about tiling over an existing tile installation rather than taking up the tile and/or underlayment and starting from fresh. How did you respond? 

Here are two situations Mark Heinlein CTI #1112 and National Tile Contractors Association
Training Director to help explore possible responses.

When you install tile, do you ensure that you have enough mortar to accommodate inherent (actual) tile warpage associated with large format tile?

Tile sizes are changing; getting larger, longer, and proportionately having more inherent warpage. Likewise, changes are being seen in tile installation methods, using thin set and large and heavy tile mortars to accommodate tile warpage.

Let's review what's involved.

CTEF has a question for you: What made you the ceramic tile installer you are today? What unique experiences affected you in such a way that you embraced education and training to become a successful Certified Tile Installer?

Seriously, if you install ceramic tile, you have a story about your journey.

When you talk with others who are successfully earning a living in the trade, they too have a story. It may be completely different than the pathway you followed, yet equally valuable.

We've all seen it: that really ugly white powder that grows on cement grout and also tile, stone, brick, and concrete, particularly when it's installed someplace with moisture (i.e., in a basement or outdoors). That white residue is called efflorescence.

This article goes into detail about efflorescence, including situations that readers have shared with us since the article was originally published in September 2016.

Fred Hueston, President and Founder of Stone Forensics, recently published Why It Is Important to Hire a Certified Tile Installer, Including CTEF Certification. Have you read it?

The article is so powerful that - with Fred's permission - we are sharing highlights with you here.

Horrified about subpar tile installation? Become a Certified Tile Installer. That's according to John Trent CTI #277, a former tile installer, and former territory manager for Schluter Systems since 2012. He was one of those subpar installers who now encourages all installers he meets to become Qualified Labor.

John is next in the CTEF Blog series about Qualified Labor based on an article in TileLetter.com titled John Trent: Certification - fighting the good fight against sub-par installations.

Note that this article is part of the CTEF classics, capturing valuable insights from the first CTIs.
