- 01
Separate concrete, masonry, coated surfaces, metal, glass-adjacent areas, joints, sealants, and landscaping. Mark grease, gum, organic growth, traffic film, mineral deposits, and previous damage so each bidder can connect the proposed method and production rate to the actual condition.
- 02
Use a representative section to confirm pressure, flow, temperature, chemistry, dwell time, agitation, rinse, and final appearance. Record any color change, coating weakness, joint leakage, overspray, or staining that the agreed method cannot safely remove.
- 03
Identify drains and low points before production begins. Protect doors, intakes, outlets, cameras, signs, landscaping, vehicles, and neighboring finishes; then establish pedestrian controls, traffic separation, and the agreed recovery or diversion measures for each work zone.
- 04
Clean in manageable sections and inspect edges, joints, spot-treated areas, and adjacent property while controls remain in place. Resolve touch-ups, remove residue, document accepted exceptions, and reopen the area only after access routes meet the written completion standard.
