Content includes sticking tests, spotting loose tiles with a mallet, checking layer joins at details, and doing flood tests in wet spots.

Topics include dry placing, balance, grout line width, tile direction, reference lines, centering on features, and handling cuts at corners, shelves, and drains for pro finish.

You will learn when to back-butter, butter-and-bed, right trowel sizes, coverage goals in wet areas, and ways to avoid empty spaces under tiles.

You will study cleaning, priming, making fillets at wall-floor joins, crack fixing, slopes to drains, and surface needs for good layer sticking.
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 part compares sheet, liquid, and cement waterproof systems for bathrooms. You will learn performance needs, base matching, common failures, and picking systems that meet rules and maker advice.
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 part explains choosing tile glues for bathroom walls and floors. You will compare cement thinset, flexible and quick-set mortars, and match to bases, tile sizes, porcelain hardness, and expected shifts or damp.

Topics include finding damp sources, removing failed plaster, cleaning white deposits and mould, and drying ways that avoid more cracks.
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, line cleaning, mixing and filling techniques, silicone at edges and fittings, and planning movement and expansion joins to stop cracks and leaks.
