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 with 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.

The second has to do with walls.

For a beautiful and long-lasting tile installation, you need to ensure that every facet of the job is completed properly according to tile industry standards and best practices. The key element here is the foundation of the installation and that's where underlayment for tile solves a multitude of problems.

Flooded tile installations have been top-of-mind lately given two extreme hurricanes within two weeks. In anticipation of questions, we're pooling together advice about how commonly dry area tile installations act as a submerged swimming pool-like installation for a period of time.

Since we don't have all the answers, we anticipate this article being a work in progress. As we come upon new information, Robb Roderick CTI #727 and Mark Heinlein CTI #1112 - both National Tile Contractors Association trainers - and I will add to this discussion. 

If you're wondering why you need to include expansion joints when installing tile, you've come to the right place. Let me explain why they are so important.

For perspective, we originally published this article in August 2016, and expansion joints continue to come up in conversation, during training sessions, and also in comments.

Does the word flat have the same meaning as the word level when it comes to floors and, more importantly, tile installation?  If we look in various dictionaries, flat and level can have almost the same definition which can be confusing. 

When you install tile in wet areas, do you ensure that everything slopes to the drain? If not, please read below.

Let's consider showers.  Showers can be a beautiful part of the bathroom especially when the tile is part of the finished product.  The beauty, though, will not be long-lasting if the installation standards and best practices for tile installation are not followed.

Do You Honor Expansion Joints in a Concrete Floor?

You do, right? Honoring expansion joints in a concrete floor is critical to the success of a ceramic tile floor installation.

How prepared are you for installing Large Format Tile (LFT) or Gauged Porcelain Tile Panels (GTPT) and ensuring you have a surface that is adequately flat?

It's a big deal and worth considering before you get started. 

Do you use an edge profile to protect your tile installation? It's particularly valuable when transitioning from tile to another flooring surface material. However, to work, the profile must be installed correctly. Let's explore.

If you're considering how to install natural stone floor tile, be aware that there's a significant difference between natural stone and ceramic tile especially when it's over wood framing.

Unfortunately, many consumers, builders and even some tile installers share the mistaken idea that natural stone tile products may be installed over a wood-framed floor in the same way as is ceramic and porcelain tile. This is completely untrue and will many times lead to a very costly replacement.

Why? Because tiles made from natural stone do not have the same strength as ceramic tiles and they require a floor system that is twice as stiff as what is required for ceramic floor tile.

Let's explore in more detail.
