Job-day checklist
Customer: [name] · Address: [ ]
System: [ ] · Area: [__ sq ft]
Date: [ ]
Crew lead: [ ]
1. Before job day
Moisture first: ASTM F1869 (calcium chloride) runs 60–72 hours and calls for three tests in the first 1,000 sq ft and one more per additional 1,000; ASTM F2170 (in-slab RH probes) can be read after 24 hours. The plastic sheet test (ASTM D4263) only shows that moisture is present. Compare results with the coating maker's limits, for example 3 lb and 75% RH.
- Moisture test done: method [ ], result [ ], maker's limit [ ]
- Data sheets read for every product: temperature limits, mix ratio, recoat window, cure times
- Safety data sheet (SDS) for every product in the truck
- Products, kits and flake on hand; quantities checked against the coverage and flake calculators
- Forecast checked for install and cure days: [low / high °F]
- Customer reminded to clear the floor; power confirmed: [120 V / 240 V]
2. Arrival and setup
Dust control is required, not optional: for walk-behind floor grinders, OSHA's silica rule calls for a water system or the maker's dust collection system with a filter of 99% or better efficiency and a filter-cleaning mechanism, plus a HEPA vacuum between passes indoors.
- Walked the floor with the customer; existing cracks, stains and damage noted
- "Before" photos taken
- Walls, doors and fixtures protected; termination edges masked
- Grinder connected to the HEPA dust extractor; HEPA vacuum on site
- PPE as the SDS requires: respirators, gloves, eye protection
3. Prep and profile
Check the profile against the chips: prepared concrete is graded from CSP 1 to CSP 10 against ICRI's replica chips. The target comes from the coating's data sheet.
- Field and edges ground; tooling and grit used: [ ]
- Profile checked with CSP chips: target [CSP __], reached [CSP __]
- Oil spots, old sealers and coatings removed
- Floor vacuumed clean, edges and corners included
4. Repairs
- Cracks opened and filled: [__ linear ft]
- Spalls and holes patched: [ ]
- Control joints [filled / left open]; isolation and expansion joints left open
- Repairs scraped flush and cured as their data sheet requires
5. Conditions log
Measure the slab, not just the air. Many data sheets require the floor to be at least 5°F above the dew point. Log a reading before every coat.
| When | Time | Air °F | Slab °F | RH % | Dew point °F | Slab − dew point | Initials |
|---|---|---|---|---|---|---|---|
| Before primer | |||||||
| Before base coat | |||||||
| Before topcoat | |||||||
| Second visit |
6. Mix and batch log
Check your spread rate as you go: area covered ÷ gallons used gives the actual square feet per gallon; compare it with the target on the scope of work. Mix full kits at the data sheet's ratio.
| Coat | Product | Lot, part A | Lot, part B | Mix ratio | Time mixed | Kits | Area covered | Sq ft per gal |
|---|---|---|---|---|---|---|---|---|
| Primer | ||||||||
| Base coat | ||||||||
| Topcoat | ||||||||
7. Application
- Primer applied at [__ mils / sq ft per gal]
- Base coat applied at [ ]; back-rolled before it turned sticky
- Broadcast: [full / partial]; flake used: [__ lb]
- Recoat window kept: minimum [ ], maximum [ ] (from the data sheet)
- Loose flake scraped and vacuumed before the topcoat
- Topcoat applied at [ ]; wet film gauge readings: [ ]
8. Cure and return to service
Give dates and times, from the data sheet, for the temperature on site. For example, a standard-cure epoxy at 72°F might allow light foot traffic after about 10 hours and heavy traffic after 2 days, with full cure after 5 days; colder slabs take longer.
- Light foot traffic from: [date, time]
- Vehicles from: [date, time]
- Full cure: [date]
- Times given to the customer in writing
9. Photos
- Before
- Ground surface next to a CSP chip
- Repairs
- Each coat, and the broadcast
- Readings and product labels with lot numbers
- Finished floor, wide and close-up
10. Walkthrough and close-out
- Floor walked with the customer; punch list done
- Care instructions and warranty handed over
- Final payment collected
- Waste and leftover product handled as the SDS and local rules require
- Review requested
- Job file saved: photos, readings, batch log, signed scope
