The Best Techniques for Installing Large Format Tiles, According to Americo Migliore

Introduction

Large format tiles have become a popular choice in modern interior and exterior designs, offering a sleek, sophisticated, and seamless look. However, installing them requires precision, expertise, and specialized techniques to ensure a flawless finish.

Americo Migliore, a renowned expert in tile and stone installation based in New York, has spent years mastering the art of large format tile installation. His experience has helped countless clients achieve durable and aesthetically pleasing tile surfaces.

In this article, we will explore Americo Migliore’s best techniques for installing large format tiles, ensuring longevity, stability, and a professional finish.

Understanding the Challenges of Large Format Tiles

Large format tiles, typically measuring 15 inches or larger on at least one side, present unique installation challenges. Unlike smaller tiles, they require extra care in handling, surface preparation, and adhesive application.

Americo Migliore emphasizes that improper installation can lead to cracking, lippage (uneven tile edges), and weak adhesion, which can compromise the overall integrity of the flooring or wall surface.

To overcome these challenges, professional techniques must be applied at every stage of the installation process.

Surface Preparation: The Foundation of a Successful Installation

One of the most critical steps in installing large format tiles is proper surface preparation. Americo Migliore highlights that even minor imperfections in the substrate can lead to serious issues once the tiles are installed.

Ensure a Level Surface – Large tiles do not flex easily, making it essential that the subfloor or wall is perfectly level. Any high or low spots must be corrected using a self-leveling underlayment or patching compound.

Thorough Cleaning – Dust, grease, or debris can weaken the bond between the tile and the substrate. Americo advises thoroughly cleaning the surface before beginning the installation.

Moisture Testing – For installations over concrete, moisture levels must be checked. Excess moisture can cause adhesives to weaken, leading to tile detachment over time.

Selecting the Right Adhesive and Trowel Size

Adhesive selection is another crucial factor in ensuring the success of large format tile installations. Americo Migliore recommends using a high-performance, polymer-modified thin-set mortar designed specifically for large tiles. These adhesives offer enhanced bonding strength and flexibility, preventing future movement or cracking.

Additionally, the correct trowel size is essential for achieving proper coverage:

A 1/2-inch x 1/2-inch square-notch trowel is typically recommended to ensure an even layer of adhesive.

For tiles exceeding 24 inches, Americo suggests using the back-buttering technique—spreading a layer of mortar on the back of each tile in addition to the substrate to improve adhesion and eliminate hollow spots.

Using a Tile Leveling System to Prevent Lippage

Lippage—uneven tile edges—can be a common issue with large format tiles. Americo Migliore emphasizes the importance of using a tile leveling system to achieve a smooth, even surface.

A tile leveling system consists of clips and wedges that help keep tiles in place while the adhesive sets, ensuring uniformity across the surface. This method prevents tiles from shifting and eliminates the risk of height variations, which can be both unsightly and a tripping hazard.

Expansion Joints: Preventing Cracks and Tile Movement

Americo Migliore strongly advises incorporating expansion joints into large format tile installations, especially in areas with high temperature fluctuations or heavy foot traffic. Expansion joints allow tiles to contract and expand naturally without causing cracks.

Some essential expansion joint considerations include:

Adding joints every 8 to 12 feet in large open areas.

Keeping perimeter expansion gaps along walls and other fixed structures to allow for natural movement.

Using flexible sealants in the expansion joints to absorb movement while maintaining a cohesive look.

Proper Grouting Techniques for a Seamless Look

Grouting large format tiles requires just as much attention as the installation process. Americo Migliore recommends using unsanded or fine-sanded grout for thin grout lines, ensuring a clean and elegant finish.

Consistent Joint Width – Large tiles typically look best with narrower grout lines (1/16 to 1/8 inch).

Epoxy or High-Performance Grout – These types of grout offer superior stain resistance and durability, making them ideal for large format tile installations.

Correct Grout Application – Excess grout should be removed promptly using a damp sponge to prevent hazing on the tile surface.

Post-Installation Care and Maintenance

Once the tiles are installed, proper care is essential to maintain their appearance and longevity. Americo Migliore advises sealing natural stone tiles to protect them from moisture and stains. Additionally, regular cleaning with pH-neutral solutions helps preserve the surface without damaging the grout or tile finish.

To avoid accidental damage, furniture pads should be used on heavy objects, and abrasive cleaners should be avoided. By following these maintenance tips, homeowners and business owners can enjoy the beauty of their large format tile surfaces for years to come.

Conclusion

Installing large format tiles requires precision, expertise, and the right techniques to achieve a flawless and durable finish. Americo Migliore’s approach to tile installation, developed through years of experience in New York’s tile and stone industry, ensures that every project is executed with the highest standards.

From meticulous surface preparation and adhesive selection to the use of leveling systems and expansion joints, following Americo Migliore’s best practices can help achieve professional results. Whether for a modern home or a commercial space, large format tiles can transform interiors with their clean lines and minimal grout joints—provided they are installed correctly.
