Practical Guide to Selecting and Installing Porcelain Slabs for Interior Floors and Walls

Selecting and installing large-format porcelain slabs requires technical knowledge, careful planning, and attention to detail. This guide provides architects, designers, and contractors with practical, up-to-date recommendations.

Selection Criteria Evaluate traffic level (PEI 4-5 recommended for floors), moisture exposure, lighting conditions, and desired aesthetic. Always request physical samples and test them on-site under actual lighting. Consider slip resistance ratings, thickness (6-20 mm typical), and edge rectification for precise joint alignment.

Installation Best Practices

  1. Verify substrate flatness (maximum 3 mm deviation in 3 meters).
  2. Use high-quality medium-bed adhesives with 95-100% coverage.
  3. Employ leveling clips and spacers for large formats to prevent lippage.
  4. Maintain proper expansion joints (minimum 5 mm at perimeters).
  5. Allow adequate curing time before grouting and foot traffic.

Maintenance Protocols Daily cleaning with pH-neutral detergents is sufficient. Avoid abrasive cleaners. Porcelain’s inherent resistance to stains and chemicals ensures effortless long-term care.

This professional approach results in durable, visually stunning interiors that exceed client expectations for both beauty and performance.
