This code provides comprehensive guidelines for the preparation, laying, curing, grinding, and polishing of in-situ terrazzo floor finishes. It specifies material requirements, including marble chips, cement, pigments, and dividing strips, to ensure durable and aesthetically pleasing floors without shrinkage cracks.
Code of practice for laying in-situ terrazzo floor finish
Quick Reference Values
maximum panel area2.0 sq.m (to prevent shrinkage cracks)
maximum panel dimension1.2 m or 2.0 m depending on layout
minimum glass strip thickness1.5 mm
minimum brass aluminum strip thickness2.0 mm
curing time before grinding5 to 7 days
under layer thickness20 mm to 25 mm
Practical Notes
Always use dividing strips (glass, aluminum, or brass) to create panels not exceeding 2 square meters to control shrinkage cracking.
Ensure proper bond between the base concrete, the under-layer, and the terrazzo topping by cleaning and applying a cement slurry before laying.
Do not begin the grinding process before 5 to 7 days of curing, otherwise, marble chips may dislodge from the cement matrix.
