General Tile Questions
What are rectified tiles?
Rectified tiles are tiles that have been precisely cut after firing to ensure clean, uniform edges. This allows for tighter grout lines and a more seamless, modern appearance. They are ideal for creating a sleek, high-end finish in both residential and commercial spaces.
Where can tiles be used?
Tile is an extremely versatile material that can be used in a wide range of applications, including:
- Floors
- Walls
- Showers
- Kitchen backsplashes
- Countertops
- Fireplaces and hearths
- Outdoor areas
Its durability and resistance to moisture make it suitable for both interior and exterior use.
Tile Maintenance & Longevity
How are tiles cared for and maintained?
Tile is known for being low-maintenance and easy to care for. Routine cleaning is key to maintaining its appearance and longevity.
Recommended maintenance includes:
- Sweeping or vacuuming regularly to remove dirt and debris
- Mopping with a mild, non-abrasive cleaner
- Avoiding harsh chemicals such as bleach, acids, oils, or wax-based products
Proper care will help preserve both the tile and grout over time.
How long does tile last?
When properly installed and maintained, tile can last for several decades. It is one of the most durable flooring and surface materials available, making it a long-term investment for both homes and businesses.
When should tile be replaced?
Tile should be replaced when:
- It becomes cracked or damaged
- Grout deterioration affects performance
- The design becomes outdated
Timely replacement helps maintain both the appearance and functionality of your space.
Tile Types & Materials
What is the difference between ceramic and porcelain tile?
Ceramic and porcelain tiles are both popular options, but they have key differences:
- Ceramic Tile: More affordable, easier to install, and suitable for most residential applications
- Porcelain Tile: Denser, more durable, and highly resistant to water and stains, making it ideal for high-traffic or commercial areas
Both options offer excellent durability and performance when installed correctly.
Do ceramic and porcelain tiles vary in quality?
Both ceramic and porcelain tiles are high-quality materials. The best choice depends on your specific needs, such as location, usage, and budget. At Posch Tile, we help you select the right material based on your project requirements.
What is the difference between glazed and unglazed tiles?
The primary difference lies in the surface finish:
- Glazed Tiles: Feature a protective coating that makes them non-porous, stain-resistant, and available in a wide variety of colors and styles
- Unglazed Tiles: Have a more natural appearance, are typically more slip-resistant, but may be more prone to staining
Each option has its advantages depending on the application.
What is a PEI rating?
The PEI (Porcelain Enamel Institute) rating measures a tile’s durability and resistance to wear. It helps determine the best tile for specific environments, such as low-traffic residential areas or high-traffic commercial spaces.
Installation & Usage
What is the difference between wall and floor tiles?
Wall and floor tiles differ in durability and thickness:
- Floor Tiles: Designed to withstand foot traffic, making them thicker and more durable
- Wall Tiles: Typically lighter and thinner, designed for vertical surfaces
Using the correct type of tile ensures safety and long-term performance.
What is the difference between interior and exterior tiles?
Exterior tiles are specifically designed to handle environmental conditions such as:
- Temperature changes
- Moisture exposure
- Freeze-thaw cycles
They often have textured surfaces for better traction and increased durability compared to indoor tiles.

Selecting the right tile involves several factors, including:
- Location (indoor vs. outdoor)
- Level of foot traffic
- Moisture exposure
- Desired style and finish
- Budget
