Getting the Coverage You Need Under Large Wall Tile

[fa icon="calendar'] Apr 3, 2018 8:30:00 AM / by Scott Carothers posted in Ask Scott, Installing Tile TIps

What challenges have you encountered getting the coverage you need under large wall tile? There are two aspects to this question. 

The first has to do size. Many projects today call for ever-increasing tile sizes, many of which are rectangular shapes such as 12” x 24”, 18” x 36”, 24” x 48”, and larger creating difficulties for the installer when bonding the tile to the substrate.

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.

How to Correctly Trowel Mortar When Installing Tile?

[fa icon="calendar'] Jan 23, 2018 7:00:00 AM / by Scott Carothers posted in Ask Scott, Installing Tile TIps

[fa icon="comment"] 20 Comments

If you're asking how to trowel mortar when installing tile, realize that you are asking a fundamentally critical question. It's so critical that readers like you have made this CTEF Blog article the one with the highest readership since we originally published it on June 7, 2016.

You see, when thin set mortar is incorrectly applied, the installation will many times fail. More likely than not, the tile will break - as you see in the image below.

Not a good situation for the customer and a terrible one for everyone involved in installing tile correctly.

Let's focus then on how to properly apply the mortar.

Prevent Problems: Read the Homeowner's Guide  to Hiring a Qualified Tile Installer

Certified Tile Installer Mike Corona says,

You don't become a tile installer or a business owner overnight. It takes time, enthusiasm, pride, reliability, respectfulness, a willingness to learn, and dedication. No two jobs are the same; each one has its own unique nuances. As a qualified installer, you need to be able to communicate how to deal with those nuances and qualify yourself to not only meet but exceed expectations. Being qualified will exponentially increase your value and you will have endless opportunities.
