### Permanent or equivalent temporary lighting shall be operating during finishing and inspection so that aggregate distribution, grinding uniformity, residual pinholes, scratch patterns, and strip alignment can be evaluated under realistic conditions.
−### The floor shall be inspected under the lighting in which it will be viewed in service, because terrazzo is frequently accepted under raking construction lighting that either conceals or exaggerates surface defects. {note}

### The matrix manufacturer's minimum thickness for the selected aggregate gradation governs.
### Cementitious system thicknesses are dictated by the system definition and the available slab recess.
−### There must be sufficient matrix depth above the slab to embed and lock the largest aggregate; placing too thin for the aggregate size leaves chips that loosen and pop out during grinding and service. {note}

## Spare material shall be stored by the Owner in the conditioned environment the manufacturer recommends.
## Because terrazzo is repaired by grinding out and re-pouring a patch with matching matrix and aggregate, attic stock of the original materials allows a future repair to be blended into the floor; a later-purchased replacement aggregate from a different batch will not match the surrounding field. {note}
