Floor substrate reference table
Match the chemistry and method to the substrate. The wrong cleaner doesn’t just under-clean — it damages the floor. Identify the substrate before procurement; pre-test every new product on a 1 sq ft area.
| Floor type | Daily method | Periodic / restoration | pH range | PPE | Key cautions |
|---|---|---|---|---|---|
| Sealed concrete (cured >28 d) | Auto-scrub or damp mop with neutral cleaner (pH 7–9). | Quarterly: alkaline degreaser (pH 10–11), rinse, re-seal annually. | 7–11 | Std | Avoid acids — etches cement paste and dulls densifier finish. |
| Unsealed / polished concrete | Dust-mop daily, damp-mop with neutral cleaner only. | Re-densify every 6–12 months; burnish with diamond pads. | 7–9 | Std | No bleach, no acid. Standing water dulls polish — squeegee dry. |
| Epoxy / urethane coating | Neutral cleaner, autoscrubber with red/white pad. | Inspect for delamination quarterly; spot-recoat where worn. | 6–10 | Std | Solvents (acetone, MEK) attack the coating. Pre-test any degreaser. |
| VCT — vinyl composition tile | Neutral cleaner (pH 7–9), mop or autoscrub. | Strip with alkaline stripper, 4–5 coats finish, burnish weekly. | 7–9 daily / 12–13 strip | Std (Resp + chem gloves for strip) | Never use solvents — softens tile. Standing water lifts tile from mastic. |
| LVT / LVP (luxury vinyl) | Neutral cleaner, microfiber flat mop. | Manufacturer-approved no-wax cleaner; do not strip. | 7–8 | Std | No alkaline strippers. Many LVT warranties void by solvent or bleach use. |
| Ceramic / porcelain tile | Neutral cleaner; alkaline for greasy areas. | Acid grout cleaner (citric/sulfamic) quarterly for restrooms. | 5–11 | Std + chem gloves (acid step) | Acid can etch unsealed grout — pre-wet grout before applying. |
| Quarry tile (kitchens) | Daily alkaline degreaser (pH 10–11), deck-scrubber. | Weekly: hot alkaline + acid de-scale on alternating weeks. | 10–12 daily / 1–3 descale | Slip-resistant boots, chem gloves, face shield (descale) | Floor drains must be uncovered. Rinse to neutral pH before re-opening. |
| Natural stone — marble / limestone / travertine | pH-neutral stone cleaner only, microfiber. | Re-seal with impregnator every 12–18 months; hone if etched. | 7 (strictly neutral) | Std | Acids, bleach, vinegar, citric all etch. No quat residue — dulls finish. |
| Natural stone — granite | pH-neutral cleaner, soft-bristle. | Annual penetrating sealer; check with water-bead test. | 6–9 | Std | Tolerates more than marble but still avoid strong acids long-term. |
| Terrazzo (cementitious) | Neutral cleaner daily. | Diamond-polish every 2–4 years; restorative crystallization annually. | 7–10 | Std | Treat as marble — no acid. Old terrazzo with epoxy matrix tolerates more. |
| Hardwood — finished | Manufacturer-approved wood floor cleaner, well-wrung mop. | Recoat (screen + finish) every 3–7 years; never wet-mop. | 6–8 | Std | Standing water swells planks. No quat, no oil soap on poly finish. |
| Hardwood — oil-finished | Specialty oil-soap or pH-neutral wood cleaner. | Re-oil high-traffic zones annually. | 6–8 | Std | Avoid water-based polyurethane cleaners — clouds the oil finish. |
| Rubber sport / mat flooring | Neutral cleaner, soft-bristle or microfiber. | Deep-clean monthly; spot-treat per manufacturer. | 7–9 | Std | No solvents, no petroleum-based cleaners — degrades rubber. |
| Carpet — commercial loop | Vacuum daily; spot-clean with neutral spotter. | Hot-water extraction every 6–12 months; encapsulation interim. | 6–9 (cleaner) / 4–5 (rinse) | Std | Over-wetting + slow dry = mildew. Acid rinse neutralizes alkaline residue. |
| Resinous self-leveling (MMA / urethane) | Neutral cleaner, soft-bristle. | Inspect joints / coving monthly; spot-recoat as needed. | 6–10 | Std + chem gloves for any aggressive step | Avoid strong oxidizers. Pre-test all cleaners on a 1 sq ft section. |
| Anti-static / ESD flooring | Manufacturer-specified ESD cleaner only. | Verify surface resistance quarterly per ANSI/ESD STM 7.1. | 6–8 (verify with mfr) | Std | Wax, quats, and many finishes destroy static-dissipative properties. |
| Painted / sealed wood (gym, stage) | Damp-mop with neutral cleaner; well-wrung. | Recoat finish per usage (typically annual for gyms). | 6–8 | Std | No standing water, no oil soap. Use approved gym floor cleaner only. |
| Slip-resistant safety flooring (Altro etc.) | Daily deck-scrub with neutral/mild alkaline cleaner. | Weekly: deep-scrub with alkaline degreaser, rinse to neutral. | 7–11 | Slip-resistant boots, chem gloves (weekly) | Aggregate traps soil — mopping alone won’t clean. Deck brush is required. |
pH reference scale — common cleaning chemistries
| pH | Category | Examples |
|---|---|---|
| 0–2 | Strong acid | Toilet bowl cleaner, descaler (HCl/sulfamic) |
| 3–4 | Weak acid | Citric/lactic descaler, some restroom cleaners |
| 5–6 | Mildly acidic | Carpet rinse, some glass cleaners |
| 7 | Neutral | Neutral floor cleaner, stone cleaner |
| 8–9 | Mildly alkaline | Daily all-purpose, dishwash detergent |
| 10–11 | Alkaline degreaser | Heavy-duty degreaser, oven cleaner |
| 12–13 | Strong alkali | Floor stripper, drain cleaner, caustic |
| 14 | Extreme alkali | Industrial degreaser, lye |
Finish & sealer quick-reference
VCT finish: Apply 4–5 coats with a clean rayon or microfiber applicator. Burnish weekly with a high-speed (1500–2500 RPM) machine and the manufacturer-matched pad. Strip and recoat every 12–18 months in heavy traffic.
Concrete densifier: Lithium or sodium silicate. Re-densify every 6–12 months in areas showing dust-up. Burnish with diamond pads (50/100/200/400 grit progression) for polished concrete.
Stone impregnator: Penetrating sealer (siloxane / fluoropolymer). Re-apply every 12–18 months. Verify with water-bead test: water should bead for at least 30 seconds.
Wood floor: Recoat (screen & coat) every 3–7 years before wear reaches stain layer. Full sand-and-refinish only when stain or substrate is compromised.
Resinous floor: Topcoat life 5–10 years depending on traffic. Annual inspection of coving, joints, and high-wear paths.

Common failure modes
| Failure mode | Why it matters |
|---|---|
| Wet-mopping LVT and laminate | Water wicks under planks at seams. Use well-wrung microfiber, no standing water. |
| Acid grout cleaner on unsealed marble | Etches in seconds. Always identify the substrate before applying any acid. |
| Quat disinfectant on polished concrete or stone | Quat residue builds up, dulls polish, attracts soil. Use neutral cleaner, separate disinfectant step on sealed surfaces only where required. |
| Skipping the rinse after stripping VCT | Residual alkaline stripper prevents finish from bonding. Two rinses with clean water before recoat. |
| Same mop for restroom and kitchen | Cross-contamination plus chemical incompatibility. Color-code mop heads by zone. |
| Bleach on natural rubber or linoleum | Oxidizes the surface, causes yellowing and breakdown. Neutral cleaner for both. |
