B. Prepare written report, endorsed by Installer, listing conditions detrimental to performance of
stone flooring.
C. Proceed with installation only after unsatisfactory conditions have been corrected.
3.2 PREPARATION
A. Vacuum concrete substrates to remove dirt, dust, debris, and loose particles.
B. Remove substances from concrete substrates that could impair mortar bond, including curing
and sealing compounds, form oil, and laitance.
C. Where indicated, prepare substrates to receive waterproofing by applying a reinforced mortar
bed that complies with ANSI A108.1A and is sloped 1/4 inch per foot toward drains.
D. Before setting stone, clean dirty or stained stone surfaces by removing soil, stains, and foreign
materials. Clean stone by thoroughly scrubbing with fiber brushes and then drenching with
clear water. Use only mild cleaning compounds that contain no caustic or harsh materials or
abrasives.
3.3 INSTALLATION, GENERAL

to match shop-cut edges.
1. Use power saws with diamond blades to cut stone.
B. Set stone to comply with requirements indicated.
C. Scribe and field cut stone as necessary to fit at obstructions. Produce neat joints of size
specified or indicated.
D. Provide control and expansion joints of widths and at locations indicated. Keep control and
expansion joints free of mortar, grout, and other rigid materials.
3.4 INSTALLATION TOLERANCES
A. Variation in Line: For positions shown in plan for edges of flooring, ramps, steps, changes in
