Why this method statement is used
This method statement is used to define and communicate the approved procedure for carrying out method statement: mosaic tile installation in wet areas and feature walls on site. It ensures the work is planned in advance, the correct resources and controls are in place, and all personnel understand responsibilities, sequence, quality requirements, and safety controls before work begins. It aligns site execution with the documented scope and acceptance expectations.
Who uses this method statement
This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.
When it is prepared and submitted
The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.
Who reviews or approves it
The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.
Important approval note
This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.
For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.

Scope
Overview
This method statement defines the procedures and quality controls for supply, preparation, waterproofing interface coordination, installation, grouting, finishing, protection, and handover of mosaic tile finishes in internal wet areas (e.g., showers, washrooms, spa zones) and architectural feature walls. It includes substrate acceptance, layout and pattern control, adhesive selection and application, grout consistency and installation, movement joints, QA/QC inspections, hold/witness points, and final inspection.
Inclusions
- Substrate verification (plastered masonry, cementitious render/skim, cement board, screed, concrete, approved waterproofing system interfaces).
- Layout set-out, datum control, and mock-up approval.
- Installation of mosaic tiles (ceramic/porcelain/glass mosaics on sheets or face-mounted) to walls and floors in wet areas and to vertical feature walls.
- Adhesive selection and application suited to substrate and tile type.
- Grouting (cementitious CG2 or epoxy RG as specified) and cleaning.
- Movement joints and perimeter sealing.
- Protection and cleaning until handover.
Exclusions
- Structural works, backing wall construction, primary screeds, and MEP rough-ins.
