*Field Tests / Site Quality Checks (QA & Workmanship Control) for adhesive*

Field tests are on-site quality assurance checks, used to verify correct mixing, application, bonding behaviour, and workmanship, using simple tools or portable equipment.

*Common Field Tests & Checks*
• Mixing / Workability Check
• Adhesive forms a homogeneous, lump-free paste
• Water dosage strictly as per manufacturer
• Visual & Slump Check
• Adhesive should hold trowel ridges
• No excessive sagging or slumping
• Coverage Check
• Random tile lifting to verify ≥85–95% coverage
• Back-buttering confirmation for large tiles
• Tapping Test (Acoustic Test – NDT)
• Rubber mallet / coin tap to detect hollow sound
• Identifies voids, air entrapment, or debonding

*Additional Pull-Out / NDT Type Field Tests (Recommended)*

• Manual Pull-Off / Break Test (Semi-Destructive)
• Tile is pulled or levered after partial curing
• Failure mode observed:
• Adhesive cohesive failure (good)
• Adhesive–tile debonding (poor)
• Adhesive–substrate debonding (poor)
• Portable Pull-Off Adhesion Test (Where Available)
• Using portable pull-off testers (similar to concrete coating tests)
• Provides indicative adhesion values (not BIS certification values)
• Useful for dispute resolution / failure investigation
• Core-Cut / Edge Exposure Check (Localized)
• Small localized removal to inspect:
• Adhesive thickness
• Ridge collapse
• Air voids
• Moisture Measurement (Substrate Check)
• Moisture meter / plastic sheet test
• Prevents bonding failure due to excess moisture
