Correct tile installation depends on substrate, adhesive, geometry, joints and working times. Every ceramic surface should be installed according to the product and installation-material instructions.
Measurements and flatness come first.
Before installation, check dimensions, quantity, flatness and substrate regularity. The surface must be stable, clean and suitable for its intended use.
Uniform application and correct coverage.
Select the adhesive according to substrate, format and environment, and follow the manufacturer's open-time and application instructions.
The installation grid is part of the design.
Spacers and levelling systems help maintain alignment and flatness. Joint width is not universal: it must follow the specific collection, format, substrate and installation conditions.
Respecting curing times prevents problems.
Adhesive and grout must cure for the times specified by their manufacturers before proceeding.
