[fa icon="calendar'] Feb 5, 2019 9:00:00 AM / by Scott Carothers posted in Ask Scott, Installing Tile TIps

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.

Never Assume You Have Sufficient Mortar Coverage. Check It.

[fa icon="calendar'] Dec 4, 2018 9:00:00 AM / by Scott Carothers posted in Installing Tile TIps, Ask Scott

Is the mortar coverage under the tile you install really important? You bet. Do you just assume that you are getting sufficient coverage?  I hope not.

As often as mortar coverage comes up in articles about tile installation, you'd think that the problem would go away.  Unfortunatelyit hasn’t, especially in exterior and shower areas, for natural stone tile, and even high profile commercial installations.

If you want your tile installation to function as it should, then don't assume you have sufficient mortar coverage. Check it. That's the best way to avoid costly callbacks and ensure a successful installation .

However, installing tile with radiant heating can get overwhelming when you realize that the Tile Council of North America (TCNA) Handbook includes multiple methods that address this type of installation. The details vary somewhat depending on the structure you are working on and which type heat source your radiant system uses - hydronic or electrical.

Back Buttering Tile: How Important Is It?

[fa icon="calendar'] Oct 16, 2018 9:30:00 AM / by Scott Carothers posted in Installing Tile TIps, Ask Scott

[fa icon="comment"] 0 Comments

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:

  • Back butter is defined as, “the spreading of a bond coat to the backs of ceramic tile just before the tile is placed.
  • Bond is defined as, “The adherence of one material to another.
  • Coverage is defined as, “A measure of the amount of material required to cover a given surface.

According to the CTEF Certified Tile Installer Manual, Transfer is defined as, “The required adhesion of a bonding material to the tile.

How Not to Install Tile on Floors, Walls and in Showers

[fa icon="calendar'] Sep 25, 2018 8:30:00 AM / by CTEF Blog Team posted in Hiring a Tile Installer, Installing Tile TIps

[fa icon="comment"] 3 Comments

Sometimes, the best way to explain how important it is to work with a Certified Tile Installer (CTI) is to show you how not to install tile on floors, walls and in showers.

This article focuses on a real-life situation where those doing the work (aka tile placers) clearly did not have the knowledge, expertise or experience to deliver a high quality tile installation. They were not CTIs.  Although originally published on 9/27/2016, it continues to speak directly and strongly about unqualified labor and the perils of poorly installed tile.

Let's explore this master bathroom installation to better understand what went wrong.
