What does this vehicular traffic coating rough-in checklist cover?

14 items across 5 sections, covering materials and conditions, substrate condition, crack and joint detailing, drains and terminations, and more. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The coating foreman walking the deck ahead of the primer crew, or the GC's superintendent releasing each pour or bay for coating.

When in the schedule should this walk happen?

After the concrete has cured and been shotblasted, before priming, while cracks and terminations are still open and can still be routed and detailed.

Why do these items ask for a photo?

10 of the 14 items call for photo evidence, 15 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a vehicular traffic coating rough-in inspection?

Coating applied over a deck that hadn't reached the moisture level the primer needs, so the base coat blisters off within weeks. Moving cracks skimmed over with base coat instead of being routed and pre-detailed, and they telegraph straight back through the wear course. Drains and the termination reglet left undetailed because the crew wanted to keep the spray running, leaving the edge open to water behind the membrane.

Can I use this checklist in RTI?

Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

Vehicular traffic coating rough-in inspection checklist

Vehicular traffic coating rough-in is the last time the work is fully visible. Once the cover inspection passes and the walls, ceilings and slabs close, every defect left behind becomes a demolition bill. This checklist walks the rough-in in the order the work goes in, with the photo each item needs before it gets buried. Work is commonly verified against manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Materials and conditions

Primer, base, top coat and aggregate labels match the system
Kit labels, lot numbers and aggregate bags on the deck read against the approved submittal; no substitute primer or mixed product lines.
Deck surface temperature above the dew point at priming
Surface temperature and dew point read on the deck itself, spread at least the primer's stated minimum; a deck warming in the sun noted, since it can outgas into the primer.

Substrate condition

Concrete cured and moisture within the primer's range
Cure age confirmed and a moisture reading taken on the actual deck, not assumed from the pour date, against the primer's stated limit.
Surface profile from shotblasting verified
Deck shotblasted to an even open profile across the bay, laitance and curing compound gone, no polished or missed strips.
Deck clean, dry and oil-free at time of priming
No standing water, dust, tire rubber or oil staining; slab surface dry to the touch across the area about to be coated.
Blasted deck checked for bugholes, pop-outs and spalls
Voids and spalls the shotblast exposed filled with a patch the maker allows, cured and ground flush with the profiled deck.
No photo
Deck water-walked for ponding before coating
Deck walked after rain or a light hose-down; birdbaths marked for the slope correction the drawings or maker allow, since the coating will not fix ponding.

Crack and joint detailing

Cracks routed and pre-treated
Working cracks chased out and filled or detailed per the system, static cracks pre-striped, before any field coat goes down.
Joints and cove details ready
Control and expansion joints treated per the detail, cove at walls and curbs formed, sealant joints not yet buried under coating.
Construction joints between pours detailed like working cracks
Where the deck was placed in more than one pour, the cold joints are routed, filled and reinforced per the system rather than coated through as flat field.
No photo

Drains and terminations

Drains detailed and dammed for tie-in
Membrane tie-in at each drain bowl detailed so the coating turns into the drain, clamping ring accessible, no coating bridging the throat.
Terminations at reglets, curbs and columns set
Reglet cut or termination bar located at the specified height, base of columns and curbs prepped for the upturn.

Release for priming

Detailed cracks and joints logged on a bay plan
Each routed crack, construction joint and control joint marked on a plan of the bay, so the final and punch walks can find them under the wear course.
No photo
Bay closed to vehicles and trades for the coating window
Barricades and entry closures agreed with the super, and no carts, lifts or trades scheduled across the bay while the coats are going down.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Coating applied over a deck that hadn't reached the moisture level the primer needs, so the base coat blisters off within weeks.
Moving cracks skimmed over with base coat instead of being routed and pre-detailed, and they telegraph straight back through the wear course.
Drains and the termination reglet left undetailed because the crew wanted to keep the spray running, leaving the edge open to water behind the membrane.
