Floor Type Identification
Before any floor care work, correctly identify the floor type — the wrong product system will damage the surface and create liability.
VCT (Vinyl Composition Tile): The dominant commercial flooring in US retail, healthcare, and education. Porous; requires sealer + multiple finish coats. Industry standard is 4–6 coats of finish on new or freshly stripped VCT.
LVT (Luxury Vinyl Tile/Plank): Increasingly common in office, healthcare, and hospitality — see the scrub-and-recoat cycle planning.. Non-porous; requires NO-buff finish or specific LVT-compatible product. NEVER apply standard VCT finish to LVT — it does not bond properly and peels.
Sheet vinyl: Similar to VCT requirements. Seam areas require careful application to prevent finish build-up that cracks at seams.
Terrazzo: Natural mineral aggregate; requires dedicated crystallization or polishing service — standard floor finish does not apply.
| Floor Type | Sealer | Finish Coats | Maintenance | Never Use |
|---|---|---|---|---|
| VCT | Metal interlock sealer | 4–6 coats acrylic finish | Buff/burnish + spray buff | LVT-only products |
| LVT | No sealer required | 2–3 coats LVT-compatible finish | Damp mop; no-buff finish | Standard VCT finish (peels) |
| Sheet Vinyl | Optional sealer at seams | 3–5 coats | Buff monthly | High-solids finish near seams |
| Rubber | Rubber-specific sealer only | 1–2 coats rubber-compatible | Damp mop; no burnish | Standard wax; alkaline cleaners |
Strip-and-Recoat Procedure
Phase 1: Stripping
- Dilute stripper per manufacturer spec (typically 1:4 to 1:8 with water)
- Apply stripper to floor with mop; allow dwell time (10–20 minutes) — do not let stripper dry
- Agitate with low-speed rotary machine (175 rpm) and black or brown pad
- Pick up slurry with wet vac or mop before it dries
- Rinse floor twice with clean water — residual stripper neutralizes new finish and prevents proper adhesion
- Allow complete drying — minimum 30 minutes; test with hand palm for coolness
Phase 2: Sealing and Finishing
- Apply sealer coat (VCT); allow 20–30 minute dry time per coat
- Apply finish coats with clean finish mop, slightly overlapping at edges
- Allow 20–30 minutes dry time between coats
- Buff or burnish final coat to desired gloss level after 24-hour cure

Safety and Slip-and-Fall Risk
The NFSI (National Floor Safety Institute) estimates that 85% of worker compensation claims in the US involve slips on wet or improperly maintained floors. During floor stripping operations:
- Post wet floor signs at ALL entrances to work area before applying any liquid
- Rope off or barricade work zone
- Use non-slip mats at transition points between wet stripped areas and dry floors
- Never perform strip operations in occupied traffic areas without complete zone exclusion

Frequently Asked Questions
How many coats of finish does VCT need?
Four to six coats of acrylic finish laid over a metal interlock sealer, on new or freshly stripped VCT. That is the industry standard specification — not a premium tier, not an upsell. If a bid you are reviewing quotes two or three coats on bare VCT, it is under-specced, and the floor will show wear far sooner than the client expects.
Can I put standard VCT finish on LVT?
No. LVT is non-porous, and standard VCT finish will not bond to the surface, so it peels rather than wearing down. LVT also takes no sealer at all. Use two to three coats of a finish specifically labeled LVT-compatible or no-buff, and confirm the product before the first coat goes down — stripping failed finish off LVT is a job nobody wants twice.
Why does new finish fail right after a strip job?
Residual stripper, almost every time. Pick up the slurry before it has a chance to dry back onto the tile, rinse twice with clean water, and then let the floor dry completely. Give it thirty minutes minimum, and put your palm flat on the surface before you seal — if the tile still feels cool, moisture is coming out of it and the sealer is going down on a floor that is not ready.
How do I tell whether a floor is genuinely dry before sealing?
Use your hand. Thirty minutes is the minimum wait after the final rinse, but time alone is not the test — press your palm against the tile and feel for coolness. A cool surface means water is still evaporating out of the floor, and any sealer applied on top of that is starting the job at a disadvantage. Wait it out; the extra fifteen minutes costs far less than a re-strip.
