Calculating required wet film thicknessNumber of coats and recoat intervalsLap details at corners and wall-floor jointsSealing around pipes, mixers and drainsCuring conditions and protection from damageLesson 3Inspection and testing: bond tests, hollow-sound detection using a mallet, waterproofing continuity checks and flood testingHere you will learn inspecting and testing waterproofing and tiles. It includes bond tests, spotting hollow tiles with a mallet, membrane continuity at details, and flood tests in wet areas.
Visual checks of membranes and detailsSimple bond and pull-off field testsHollow-sound detection with a rubber malletFlood testing shower bases and floorsDocumenting defects and repair proceduresLesson 4Tile layout and set-out: dry layout, symmetry, grout joint width, tile orientation and reference linesHere you will learn planning tile layouts in bathrooms. Topics cover dry laying, symmetry, grout widths, orientations, reference lines, centering on features, and handling cuts at corners, niches, and drains.
Reading plans and measuring the bathroomEstablishing control and reference linesDry layout to test pattern and cutsChoosing grout joint width and alignmentCentering tiles on key visual featuresLesson 5Tile fixing methods: back-buttering, butter-and-bedding for floors, wall adhesive application methods and correct trowel sizesThis part explains proper tile fixing for bathroom walls and floors. You will learn back-buttering, butter-and-bedding uses, trowel sizes, coverage in wet zones, and void-avoiding techniques.
Choosing trowel notch size and patternBack-buttering large and dense tilesButter-and-bedding for floors and fallsAchieving minimum coverage in wet zonesAvoiding voids and air pockets under tilesLesson 6Substrate preparation for waterproofing: primers, fillets at wall-floor junctions, surface profile requirementsThis part covers pre-waterproofing prep for bathroom bases. You will study cleaning, priming, fillets at wall-floor joins, crack fixes, falls to drains, and profile needs for strong 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 part compares sheet, liquid, and cementitious systems for bathrooms. You will learn performance standards, base matching, failure types, and selecting code-compliant, maker-guided systems.
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 thinset, flexible and rapid mortars, matching to bases, tile sizes, porcelain density, and 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 assessing wet-damaged stone and block walls before waterproofing. Topics include source diagnosis, failed render removal, efflorescence and mold cleaning, and drying to prevent 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 grouting and sealing tiled bathrooms, covering grout kinds, cleaning, mixing and packing, silicone at edges and fixtures, and placing movement joints to stop cracks and leaks.
