Lesson 1Tile dimensions, large-format definitions, thickness, rectified edges and implications for installationThis section defines porcelain tile formats, thickness ranges, and rectified edges commonly used in Ghana. You will learn how these factors affect layout, lippage control, mortar selection, coverage targets, and handling of large and heavy panels in humid conditions.

You will learn how to select metals, PVC, and Schluter-type systems, design movement and control joints, and protect exposed tile edges safely against weather exposure.

You will learn joint types, spacing rules, perimeter detailing, sealant selection, and how to integrate structural and tile movement requirements to prevent cracking.

You will review TCNA Handbook methods and ANSI A108, A118, and A136 requirements, and learn how to select compliant systems for each project while considering local building norms.

You will learn mixer types, trowel selection, slaking and remixing, slurry bond coats, and storage practices that preserve product performance against humidity.

You will learn properties of concrete, cement board, and drywall, how moisture and movement affect them, and how to diagnose cracks, debonding, and mould risks in tropical settings.

You will learn how FF/FL values translate to tile tolerances, how to verify deflection, and how to form safe, drainable wet-area surfaces for rainy seasons.

You will study joint sizing, movement accommodation, stain and chemical resistance, colour consistency, and how to match grout type to service conditions in humid environments.

You will compare polymer-modified thin-set, large-and-heavy tile mortars, and epoxy adhesives, focusing on selection by tile size, substrate, and exposure to tropical weather.

You will compare sheet and liquid membranes, shower systems, and vapour retarders, and learn compatibility rules with mortars, backers, and drains to prevent leaks.

You will learn glazed vs through-body construction, PEI and abrasion classes, water absorption limits, and how to read manufacturer data sheets for local availability.
