Prep a warehouse slab for a new coating by running a 30/40 metal-bond grind across the whole floor with a 600-800 mm planetary grinder, then a 60/80 pass to bring the profile to CSP 2-3. Use three trapezoid discs per head, such as the triple-round-segment disc, and keep a HEPA dust collector on every machine. Plan 150-250 sqm per day per crew of two. Stop when the whole slab has a uniform matte gray texture, no trowel marks, and no glossy patches. Coat within 48 h. Most warehouse coating failures come from under-prep, not from the coating itself.
A warehouse slab is not a garage. Walk the floor before you quote and measure what is actually there.
| Condition | What it means | Extra tooling needed |
|---|---|---|
| Power-troweled finish | Dense, smooth, needs 30/40 | Standard trapezoid |
| Old epoxy peeling | Strip first | PCD trapezoid |
| Laitance dusting | Weak top layer | 30/40, maybe 20/30 |
| Oil soaked zones | Will not bond | Cut out and patch |
| Joints spalled | Profile around joints | Edge grinder |
| Grooved / shake-on hardener | Need aggressive grind | 20/30 metal bond |
Warehouse work is a fleet problem. One 800 mm grinder covers 200 sqm/day; a 10,000 sqm warehouse takes 50 machine-days. Plan accordingly.
You are not polishing - you are profiling. Stop when the profile is even.
If the slab needs a mechanical profile for grip (anti-slip warehouse coating), add a light bush-hammer plate pass after 60/80 to create a 1-2 mm texture.
Do not hand the floor to the coating crew until these checks pass:
150-250 sqm per 8-hour shift per machine at 30/40. At 60/80, 250-350 sqm/day.
Yes, with a dust-shrouded grinder and sound barriers. Plan for delivery trucks and forklift traffic - cordon off the work zone.
No. Densifier is for polished concrete, not coated floors. Adding it weakens the coating bond.
Within 24-48 h. Longer and the open pores re-carbonate. If more than 72 h, give a light 60/80 touch-up before coating.
Warehouse coating prep is a production job: fleet, grit sequence, dust control, and QC. Run 30/40 then 60/80, hit CSP 2-3, vacuum twice, and coat within 48 h. JOY TECH supplies matched trapezoid disc sets for every major warehouse grinder brand, so your crew never waits on tooling.
