Lesson 1Cutting and shaping tiles: wet saw, angle grinder, nippers and proper edge finishingThis section covers safe and accurate cutting and shaping of tiles. You will compare wet saws, angle grinders, and nippers, learn edge finishing methods, dust control, and techniques for neat cuts around fixtures, niches, and floor wastes.

You will study cleaning, priming, forming fillets at wall-floor junctions, crack treatment, falls to drains, and surface profile requirements for reliable membrane adhesion.
Cleaning and decontaminating substratesSelecting and applying suitable primersForming cementitious fillets at junctionsTreating cracks, holes and surface defectsChecking falls, flatness and surface profileLesson 7Waterproofing strategies: sheet membranes, liquid-applied membranes, cementitious waterproofing — selection criteria and compatibilityThis section compares sheet, liquid, and cementitious waterproofing systems for bathrooms. You will learn performance criteria, substrate compatibility, typical failure modes, and how to select systems that meet codes and manufacturer guidance.
Sheet membranes: types, uses, limitationsLiquid-applied membranes: key propertiesCementitious coatings for wet areasCompatibility with substrates and primersChemical resistance and service conditionsLesson 8Tile adhesive selection: cement-based thinset, flexible mortars, rapid-set adhesives — selection by substrate and tile typeThis section explains how to choose tile adhesives for bathroom walls and floors. You will compare cement-based thinset, flexible and rapid-set mortars, and match them to substrates, tile formats, porcelain density, and expected movement or moisture.
Cement-based thinset classificationsFlexible mortars for movement-prone basesRapid-set mortars: uses and limitationsAdhesive choice for porcelain and large tilesAdhesive compatibility with waterproofingLesson 9Assessing moisture-damaged masonry and block walls: cleaning stains, removing failed render, and drying strategiesYou will learn how to assess moisture-damaged masonry and block walls before waterproofing. Topics include diagnosing moisture sources, removing failed render, cleaning efflorescence and mold, and controlled drying strategies that avoid further cracking.
Identifying moisture sources and pathwaysTesting masonry moisture contentRemoving loose render and contaminated layersCleaning efflorescence, mold and stainingDrying strategies and re-rendering timingLesson 10Grouting, sealants and movement joints: grout types, joint cleaning, silicone sealants at perimeter and fixtures, and expansion joint placementYou will learn how to grout and seal tiled bathrooms, including grout types, joint cleaning, mixing and packing techniques, silicone at perimeters and fixtures, and designing movement and expansion joints to control cracking and leaks.
