Jobsite preparation for concrete polishing

Confirm how much floor will be available at one time and how long each section will remain accessible. Remove stored materials and debris from released areas, and coordinate access so other trades do not interrupt active polishing work.

Our construction-sequencing guide explains how polishing fits around partitions, finishes and fixtures.

In occupied buildings, agree on work-area separation, occupant notices and permitted working hours with the facility team.

Craftsman reviews the concrete before proceeding with the specified finish. Confirm contamination removal, repair allowances and how conditions revealed during grinding will be addressed.

Where ACI 310.1-20 applies, unsatisfactory conditions must be corrected or an authorized remediation plan approved in writing before work begins. Starting work in an area is construed as acceptance of its surface conditions.

Our slab-acceptance guide covers that review. Additional preparation and repairs need an agreed scope, cost and schedule before execution.

The building enclosure must protect the polishing work from rain, wind and other adverse weather.

Where incorporated into the project, ACI 310.1-20 requires:

• A slab temperature of at least 50°F before work begins, with provisions to maintain that minimum.
• Ambient and surface temperatures that meet the instructions for each product used.
• A building shell sufficiently complete to protect the work from damaging weather.

A room-air reading does not establish the slab temperature. Meeting the ACI minimum also does not replace the application requirements for the selected densifier, dye, stain guard or repair material.

Our ACI specification guide explains when these provisions apply and how project-specific requirements take precedence.

Coordinate HVAC startup and intended operating conditions with joint filling. Our joint-filling schedule guide addresses that timing.

Before mobilization, Craftsman confirms the service requirements for the equipment and products planned for the work. The project scope should identify who provides each service and when it will be available.

ACI 310.1-20 requires suitable water, power, lighting and ventilation before work begins. Its lighting minimum is 40 foot-candles measured at the slab surface. That is a work-readiness requirement, not a substitute for the lighting and criteria used to approve the finished appearance.

Electrical capacity and connections need to match the actual equipment. Ventilation must address the selected products and tasks.

Craftsman collects polishing slurry and washwater for disposal through approved methods. We never discharge it into storm drains. Confirm the collection area and disposal arrangements before work starts; our slurry collection and disposal guide explains the process.

We also coordinate and install the agreed floor protection. Establish who maintains it after our crew leaves and how later trades will access the area. Our construction-protection guide covers those arrangements.

Release the floor for traffic and cleaning according to the installed treatment and project requirements. Our return-to-service guide distinguishes those milestones.
