100+ Free Floor Care Technician Practice Questions

The IICRC FCT has no prior credential prerequisite — it is an introductory IICRC certification. Candidates must complete an IICRC-approved Floor Care Technician course (typically two days: classroom instruction plus hands-on training with stripping, finish application, and burnishing). After course completion, candidates have a 45-day online window to take the exam at the $80 fee. Certification is maintained through annual renewal and IICRC continuing education credits (CECs).

VCT (vinyl composition tile) is the primary candidate for traditional strip-and-refinish with acrylic floor finish. Sheet vinyl with a urethane-protected wear layer and most LVT/LVP are not stripped and refinished — they are maintained with neutral cleaners and not coated. Linoleum can accept compatible polymer finishes but requires neutral-only cleaning and special low-alkaline strippers — never high-alkaline strippers (which dissolve linoleum's natural binders). Wood floors are not stripped with chemical floor stripper; they are screened (lightly abraded) and recoated with polyurethane every 3-5 years. Laminate is never wet-stripped or coated. Terrazzo and polished concrete are diamond-honed and polished, not stripped.

Floor strippers are highly alkaline (pH 10-14) and leave alkaline residue on the floor even after rinsing. If finish is applied to a still-alkaline surface, the bond between finish and floor will be compromised — the finish will lift, peel, powder, or fail prematurely. Neutralizing with a mildly acidic solution (such as a dilute citric acid neutralizer or a product labeled as a floor neutralizer) restores the floor's pH to approximately 7 (neutral). After neutralizing, rinse with clean water and verify pH with test strips before applying sealer or finish.

After a strip, apply 1-2 coats of floor sealer first on porous substrates such as new or freshly stripped VCT, then apply 4-6 thin coats of floor finish. Each coat should dry 20-45 minutes (varies by finish, temperature, and humidity) before the next coat. The first coat establishes a base; later coats build film thickness for durability and gloss. After the final coat, allow 24-72 hours of cure before high-traffic use or burnishing — early burnishing can damage uncured film. For interim maintenance, apply 1-2 recoats (spray-buff or mop-on) every 1-3 months to maintain gloss and protect the base coats.

A floor sealer is a base coat applied to porous substrates such as freshly stripped or new VCT. It seals the pores, bonds to the substrate, and provides a uniform surface for finish to adhere to. Sealers may be acrylic or solvent-based. A floor finish (sometimes called wax, though most modern finishes are acrylic or styrene-acrylic polymer rather than true wax) is the durable, glossable top coat applied over the sealer. Finish provides gloss, slip resistance per ASTM standards, scuff resistance, and is the layer that burnishes. The general sequence: substrate → sealer (1-2 coats) → finish (4-6 coats) → burnishing once cured.

A UHS (Ultra High Speed) burnisher operates at 1,000-3,000 RPM, with most production machines in the 1,500-2,500 RPM range. Electric UHS burnishers typically run 1,500-2,000 RPM and require a power cord. Propane UHS burnishers run 2,000-3,000 RPM, are untethered (best for large open areas like big-box retail and warehouses), and require carbon monoxide (CO) monitoring and dust-control filtration on the machine because propane combustion exhaust and burnishing dust must be managed. UHS burnishing restores high gloss by frictional heat that softens and re-flows the top of the polymer floor finish — it does not add finish, only restores it. Burnishing requires a fully cured finish and a clean, dust-mopped floor.

Terrazzo and polished concrete are mineral floors — they are not coated with polymer finish. They are mechanically polished using progressively finer diamond abrasive pads (typical sequence: 50, 100, 200, 400, 800, 1,500, and 3,000 grit). For polished concrete, a lithium silicate (or sodium silicate) densifier is applied between coarse and fine honing steps — it penetrates the concrete and reacts with calcium hydroxide to form additional calcium silicate hydrate, hardening the surface for higher polish levels. Routine maintenance is daily dust mop and damp mop with a neutral cleaner; never apply acrylic floor finish to polished concrete or terrazzo — it dulls the natural gloss and is not how these floors are designed to be maintained.
