Purpose
Quick-reference for living with the densified (uncoated) concrete floor. The main slab is finished with a DIY lithium-silicate densifier instead of a polyaspartic coating — see the decision record and Floor Densifier Application for product and application.
The whole point of this choice was to remove the floor-protection burden. There are no pads to cut, no casters to swap, no annual pad inspections. This page is short on purpose.
The good news: almost nothing to protect
A densifier penetrates into the concrete and reacts with it — there is no surface film to scratch, chip, burn, or bond to. That eliminates everything the old coating-protection plan required:
| Old coating requirement | With densified concrete |
|---|---|
| UHMW-PE caster cups under stationary equipment | Not needed — nothing bonds to bare densified concrete |
| Polyurethane caster swaps on rolling equipment | Not needed — factory casters are fine on concrete |
| Engineered sandwich pads under jack stands | Not needed — see point-load note below |
| Hot-work blankets/steel plate to protect the floor | Not needed — inorganic concrete shrugs off slag (still follow fire-safety practice) |
| Annual pad inspection + 5-year equipment shuffle | Not needed |
| Move-in caster-swap choreography | Not needed — just bring equipment in |
Point loads are about the concrete, not a coating
Jack stands and shop-press feet still concentrate load. On a properly cured slab this is rarely an issue, but if a thin stand foot is digging in or you want to spread a heavy point load, a scrap of plywood or a steel plate under the foot is all that’s required — no engineered pad stack. See Jack Stand Selection.
What densified concrete doesn’t do
A densifier reduces dust and tightens the pores; it is not an impermeable barrier. So a little ordinary care keeps the slab looking good:
- Wipe oil, brake fluid, and coolant promptly. Densified concrete absorbs far less than raw concrete, but a puddle left for days will still leave a shadow. Drip pans under known leakers; a rag and a bit of degreaser for fresh drips.
- Sweep or vacuum grit. Same as any shop floor — keeps abrasive debris from being ground in underfoot or under tires.
- Mop occasionally with water or a pH-neutral cleaner. Avoid acids (they attack concrete) and harsh degreasers used neat.
Optional: mats in the vehicle bays
Nothing needs to go on the densified slab — but if you want to protect the high-drip zones (especially under the 2-post lift), an optional sacrificial covering in the bays is reasonable. It catches oil/fluid drips and keeps the concrete clean (which also preserves the future-coating option). This is a want-to, not a must, and best decided after some real-world use.
- Solid wipe-clean vinyl (e.g., G-Floor Diamond Tread 75 mil) for parking bays — oil/chem-rated, takes rolling jacks/carts, never saturates.
- Under the lift: flat covering cut around the baseplates (they stay on bare concrete) + small replaceable absorbent pads at the drip points. Skip raised-edge containment mats under the lift — cutting around the baseplates breaks the dam.
- Avoid: carpet-top mats, nitrile mats with drain holes, interlocking tiles, and recycled/SBR rubber (oil reaches the slab or degrades the mat). Keep absorbent material small — saturated absorbent is a fire load near hot work.

Maintenance
- Re-apply densifier per the manufacturer’s interval/guidance (typically only if the surface starts dusting again after years of heavy wear) — a quick spray-and-broom refresh, no equipment to move out. See Floor Densifier Application.
- No pad/caster inspection cycle — there’s nothing to inspect.
If you ever decide you want a coating
The densifier doesn’t foreclose a future polyaspartic coating — installers grind/shot-blast to a bare profile as standard prep, which removes the densified layer. But the cheap, clean window is before the 2-post lift is anchored and before the slab is oil-stained. Coating around a bolted-down lift after a decade of fluid drips is the costly path (oil contamination is the #1 cause of coating delamination). See the decision record for the full reasoning.
