## Spare material shall be from the same lots as the installed tile and shall be stored by the Owner in a dry, protected location.
## Attic stock allows the Owner to repair damaged areas with tile from the same shade and caliber lot as the original installation, which is essential because later-purchased replacement tile will be from a different lot and will not match in shade or dimension. {note}
