Ceramic Tiling CONQUAS Guide

Singapore's Ceramic Tiling (Third Edition) is a Building and Construction Authority (BCA) Good Industry Practices guide in the CONQUAS Enhancement Series. BCA says the guide shares good practices for achieving quality ceramic tiling, with practical illustrations of tile types, quality checks and installation methods; the third edition adds practices, photographs and tables for clearer reference (BCA Ceramic Tiling, accessed 2 September 2026).

Materials and tiling as a system

The guide treats a tiling finish as a coordinated system rather than a tile selected in isolation. The relevant components include the substrate, adhesive, tile or stone, grout and movement joints, and their compatibility affects the finished result (BCA Ceramic Tiling guide, accessed 2 September 2026). Its scope includes ceramic, natural-stone and mosaic wall and floor tiling in the conditions described by the guide, as well as terrazzo, natural-stone and agglomerated-stone tile or slab flooring. The specific application, environment and material manufacturer's instructions remain important to the project decision.

Design and preparation

The Ceramic Tiling guide organises good practice across design, delivery, handling and storage, preparatory works, installation, protection, common feedback and maintenance. Design and preparation are not administrative preliminaries: the guide's material references cover tile selection, adhesives, grout joints, movement joints and waterproofing, while its inspection material includes checking the substrate before screed or tile work begins (BCA Ceramic Tiling guide, accessed 2 September 2026). A sound installation therefore depends on substrate condition, material compatibility, curing and the sequence of work, not only on the appearance of the completed surface.

Installation and quality checks

The guide uses practical quality checks and inspection-and-test-plan concepts to help project teams identify defects during the work. Examples in BCA's associated ceramic-tiling inspection material include checking that the substrate is flat, solid, clean and free of foreign material; ensuring screed is level without cavities; following the adhesive manufacturer's instructions; fitting tiles true to level; maintaining uniform joint widths; and observing a hold point before grouting (BCA Ceramic Tiling inspection guide, accessed 2 September 2026). These checks support workmanship quality and records during construction; they do not mean that one visual checklist resolves every structural, waterproofing or safety question.

Protection, feedback and maintenance

Protection and maintenance form part of the guide's quality lifecycle. BCA's natural-stone installation quick guide, which complements the tiling guidance, sequences surface preparation, screed or render, adhesive application, stone laying, grouting and protection, including restricting access to completed work while finishes set (BCA Natural Stones Installation quick guide, accessed 2 September 2026). The Ceramic Tiling guide's common-feedback and maintenance sections help teams address workmanship issues and care after installation rather than treating handover as the end of quality responsibility.

Relationship to CONQUAS and statutory requirements

The Ceramic Tiling guide sits within BCA's construction-quality and CONQUAS good-practice resources. It helps practitioners and contractors improve workmanship, but it is not itself a blanket replacement for project specifications, applicable Singapore Standards, Building Control requirements, professional advice or the terms of a contract (BCA CONQUAS, accessed 2 September 2026). A guide recommendation should therefore be interpreted in the context of the relevant tiling system, project conditions and current requirements.
