Big Trend: Big Tile

The past three decades have seen new manufacturing techniques and cutting-edge printing pushing porcelain tile into the forefront of design and innovation. Porcelain tiles are also getting larger and larger. Tiles equal to or greater than one square meter (almost 11 square feet!) are designated “Gauged Porcelain Tile Panels/Slabs” by  ANSI A137. 3. Additionally, while standard-body porcelain tiles are thicker than 7mm, porcelain panels range from 3 mm to 6.5 mm, with the thicker slabs (used for countertops and the like) around 12 mm thick.

When porcelain panels first arrived in the U.S. from Italy, there were no product standards or guidelines for transporting, cutting, and installing the material. The Tile Council of North America (TCNA) soon realized they needed to create guidelines for installers and the architecture and design community. After more than four years of cross-disciplinary industry collaboration and 4,000 hours of research, in 2017, the TCNA unveiled two new standards for the materials:

ANSI A137.3, the American National Standard Specifications for Gauged Porcelain Tiles and Gauged Porcelain Tile Panels/Slabs

ANSI A108.19, Interior Installation of Gauged Porcelain Tile and Gauged Porcelain Tile Panels/Slabs by the Thin-Bed Method Bonded with Modified Dry-Cement Mortar or Improved Modified Dry-Set Cement Mortar.

Now that the industry had both product standards and installation guidelines for this new porcelain product, the mystery surrounding the panels was removed, with porcelain panels and slabs increasingly selected by designers and specifiers for both commercial and high-end residential projects.

Due to advanced manufacturing processes, the panels can be installed with minimal grout widths, and thanks to their large size, the number of grout lines is minimized, allowing for a clean, modern look. The designs available are nearly endless, and many patterns can be book-matched. Also, installing directly over other surface materials is often possible with proper substrate preparation.

Let’s look at all the great reasons to love porcelain panels!

Porcelain Panels are Stylish and Modern

Available in a vast array of colors, patterns, and finishes, porcelain panels offer a modern, luxury aesthetic.

Porcelain Panels are Durable

Unlike some natural stones, porcelain panels are extremely durable, water-resistant, scratch-resistant, and easy to maintain (with fewer grout joints to clean!), making them perfect for high-traffic commercial spaces. They are also UV – and weather-resistant, making them suitable for outdoor installations.

Porcelain Panels are Perfect for Sustainable Installation Projects and Economical, Too

Porcelain panels are a smart, sustainable surfacing choice as they are long-lasting, and their manufacturing process consumes less energy due to their reduced thickness. The thinner construction means less material is used, reducing the cost per square foot. It also means the weight of the panels is also lessened for more economical shipping.

Porcelain Panels are Versatile

Porcelain panels can be cut into virtually any size and shape; this includes varying thicknesses and even curved edges. Commercial designers have welcomed the panels and specify them as an alternative to standard-body commercial tile on floors and walls in elevator banks, reception areas, guest rooms, bathrooms, and more.

Porcelain Panels Offer the Possibility of Tile-Over-Tile Installation

Installing porcelain panels over existing floor and wall materials is often possible. Tile-over-tile installations are a boon for commercial projects because they create an excellent opportunity to eliminate demolition with its associated expense, mess, and downtime.

Let’s Talk About Grout!

Let’s talk about grout! While not the most exciting component of a tile installation, grout is an important piece of the big picture. Choosing the right grout for your project, budget, and performance requirements is essential. Let’s look at the different types of grout and when to use them.

Standard Cement Grout

Standard cement grout is the most common and most economical of all the grouts. It’s been around forever, and all installers are familiar with it. Installation is straightforward, and it’s easy to clean up after installing. The downside is this grout is porous and should be sealed with good quality sealer (which adds to the labor costs). And the sealer will likely need to be replaced every few years. Standard cement grout is a solid choice if you are on a budget, but it is best suited for areas that won’t get wet or soiled.

Within the standard cement group category, we have two types: sanded and non-sanded grout. Sanded grout is sand mixed with portland cement. The sand adds strength and helps to reduce joint shrinkage. Use sanded grout in joints 1/8” or greater. It’s appropriate for floors, unpolished porcelain tiles, and natural stone tile.  Use non-sanded grout when the joints are 1/8” or less or for tile that scratches easily, like glass, marble, metal, mosaic tile, and highly polished ceramic or porcelain.

High-Performance Cement Grout

High-performance cent grout is what it sounds like — it’s a premium grout with higher performance because it is less porous and has more strength than standard grout. They are harder and denser, with better stain resistance, and are more consistent in color. They are more expensive than regular portland cement grouts, but with typical joint widths today between 1/8″ to 3/16″ (versus the 1/4″ average width used in the past), and with large formats more on-trend, the cost per square foot becomes less, making high-performance grouts only slightly more expensive.  Use high-performance cement grout on floors, walls, backsplashes, bar backs, countertops, shower enclosures, steam showers, and tub surrounds.

Ready-To-Use Grout

Ready-to-use grout (RTU) from the pre-mixed grouts of yore into high-performance material that is faster to install, and in terms of stain and chemical resistance, this grout has been compared to epoxy grout. But unlike epoxy grout, RTU is much easier to install. There are different types of RTU grouts and are comprised of either a urethane, acrylic, or hybrid chemistry. RTUs are also a good choice if you want brightly colored grout.

Epoxy grouts meet or exceed industry standard, ANSI A118.3. Epoxy grout is considered the most durable and robust of all grouts and has superior stain and chemical resistance. Installation, however, is more challenging as epoxy grouts are generally two- or three-component mixtures that require special mixing and handling at the job site. Use epoxy grout for backsplashes, floors, high-traffic areas, and demanding commercial environments such as healthcare, commercial kitchens, restaurants, and schools.
