Commercial Floors: Know What Yours Is Before Anyone Strips, Finishes or Burnishes It

By Chris, Owner

When a lease turns over or a cleaning vendor changes, the floor program usually gets set by whoever bids on it, based on how the floor looks. A glossy floor gets quoted for finish and burnishing. A dull one gets quoted for a strip. The quote rarely says what the floor is.

That works on vinyl composition tile, which is built to carry a finish that wears, gets stripped and gets replaced. It is not what the manufacturers describe for a polished concrete lobby, a marble entry or a porcelain corridor. On urethane-coated vinyl plank in a medical suite, finish is usually an option the manufacturer leaves to the owner, and taking it has consequences.

Two decisions deserve the most care. One is putting the wrong chemistry or abrasion on a floor whose surface is the material itself or its factory coating, which does damage a new coat of finish will not fix. The other is starting a finish program on a floor that never needed one, which commits the floor to a strip cycle and, on some products, moves the warranty. At the far end, one LVT maker, Interface, says wax damages its LVT and that it is "not aware of any methods to reverse this damage." Both decisions are avoidable if the floor is identified first, and the cheapest place to establish what it is tends to be the building's records.

Removable film, factory wear surface, or the material itself

Green Seal's floor-care standard, GS-40, defines floor finish as a product that leaves "a protective wax, polymer, or resin coating that is designed to be periodically removed (stripped) and reapplied." In effect it is a sacrificial layer: traffic wears the finish instead of the floor, and the finish is renewed.

Commercial hard floors are maintained in one of three ways:

• A removable film. The floor carries finish, and the program renews it. VCT is the standard case: Tarkett's VCT guide calls the factory finish temporary and says "Additional coats of floor finish must be applied after installation."
• A factory or installer wear surface. The manufacturer builds in the surface, usually a urethane layer on resilient flooring or the resin itself on epoxy and urethane floors, and says it needs no finish.
• The floor material itself. Ground-and-polished concrete, natural stone, porcelain, and terrazzo without a removable coating. Maintenance is care of the material.

Which model applies is a fact about the specific product and what has been applied to it since. Category name and shine don't settle it. Some solid vinyl tile and some rubber are designed as finish floors, and terrazzo, stone and acrylic-sealed concrete can all carry a strippable coating.

A first coat of finish turns the finish into the wear layer

Applying finish to a floor in the second or third group moves it into the first, and the manufacturers who address this are specific about what follows. Patcraft's resilient maintenance guidelines say "Applying finishes will change the original product and the finish becomes the wear layer." Milliken says "Use of a finish will require the finish to become part of the regular maintenance routine." Mannington calls finish on its floors "entirely optional," and says that once it is applied, "the warranty as well as other performance characteristics fall on the manufacturer of the floor finish (polish)."

The Marble Institute of America's care guide (now the Natural Stone Institute) notes that a topical sealer often shifts the maintenance program from caring for the stone to maintaining the sealer, stripping and reapplying it, and that it can build up into a layer less durable than the stone.

None of this makes finish wrong on those floors; several makers permit it. It makes the first coat a decision the next vendor inherits: a strip cycle that did not exist before, and on some products a different party answering for how the floor performs.

Where a floor's identity is written down

The paperwork that identifies a floor rarely follows the building. The Resilient Floor Covering Institute's maintenance guide notes that "O&M manuals or project close-out documents often do not reach the end user." The records need to answer two questions: what was installed, and what has been added since.

Where to look:

• Specifications and maintenance data. Projects specified to common practice, federal guide specifications for example, require the contractor to submit the manufacturer's maintenance data at closeout. A specifier's note in the federal resilient flooring guide specification treats wax versus no-wax as a project choice: "Pre-waxed flooring and flooring that does not require wax need not be waxed after installation if properly protected."
• Product data sheets, which the AIA's standard general conditions turn over at completion as a record of the work. A resilient data sheet names its ASTM specification (F1066 for vinyl composition tile, F1700 for solid vinyl tile and plank) and usually the factory finish: an Armstrong VCT sheet says "polish required before traffic," an Armstrong LVT sheet lists a urethane finish.
• Attic stock. RFCI treats spare material as part of long-term maintenance; ask whether any was left and where.
• A terrazzo system letter. NTMA's restoration guide specification calls for a "letter clearly identifying the terrazzo system (Epoxy, Cement, etc)."
• The owner's asbestos records. OSHA requires building owners to keep records of asbestos-containing material and transfer them to successive owners (29 CFR 1910.1001(j)(3)). For an older resilient floor, ask for these first.

What can be observed without risk is limited. Resilient flooring comes as tile, plank or roll, and heat-welded seams mark a sheet installation. Divider strips identify terrazzo, but cement and epoxy systems both use them, so the strips do not tell you which binder you have.

Past that, testing becomes the risk. The Marble Institute of America's legacy guide documented an acid test for identifying stone, and attached its own warning that the test itself may etch the stone, and that it may not work at all if the stone has been sealed or coated. Water beading on concrete is no better guide: W. R. Meadows treats beading as a sign that a penetrating sealer is still working, so a slab that beads water is not necessarily a coated one.

The terrazzo and natural stone associations tell owners to learn which system or stone they have and point them to a professional (NTMA to an NTMA terrazzo contractor, NSI to a stone specialist), but neither publishes a method for identifying it.

One material name, several maintenance programs

Vinyl tile, plank and sheet

On urethane-coated LVT and sheet, most makers say finish is optional. In AHF's words: "Polish is not required for Armstrong Flooring LVT or Sheet, however it will not negatively impact the performance of the floor." And some solid vinyl tile is designed to carry floor finish; Tarkett's SVT guide, for example, prescribes finish, stripping and burnishing.

On burnishing, Milliken says: "LVT should NEVER be burnished. If a gloss finish is desired, use an appropriate commercial grade finish." AHF tells owners not to dry buff or burnish the unpolished surface. The exception is deliberate: Tarkett's iQ homogeneous tile and sheet line is designed to be dry buffed with no finish at all.

Rubber

Roppe says "None of our rubber flooring products require a floor finish," yet Tarkett's Johnsonite Arcade rubber sheet is meant to receive finish before it goes into service. Roppe also specifies a cleaner pH of 6.5 to 8.0 at time of use and says chemistry designed for hard-surface floors or floors with finishes should not be used on rubber. Its warranty language says incorrect chemistry "can and will cause damage to the product that is not covered by the product warranty." Rubber in a gym or fitness area follows the same brand-specific rule.

Terrazzo

NTMA describes three binders: Portland cement, polyacrylate-modified cement, and, most common today, epoxy resin. The coating system matters as much. NTMA's Sealer Reference Guide separates removable sealers ("commonly referred to as floor finishes"), polyurethane or epoxy coatings that cannot be chemically stripped, and densified floors. Only the first is a strip-and-reseal floor. For routine cleaning, NTMA calls for neutral-pH cleaners and tells owners not to use "purely surface waxes," citing slippery surfaces.

Natural stone

The Natural Stone Institute divides stone into calcareous (marble, limestone, travertine, onyx), whose calcium carbonate "is sensitive to acidic solutions," and siliceous (granite, slate, quartzite, sandstone), which is generally more resistant, though NSI still advises against acidic cleaners on it. The MIA guide calls for neutral (pH 7) cleaners. An etch is damage no cleaner removes; NSI directs etched areas to a professional stone restorer.

Concrete

"Concrete" covers four different floors. ACI defines polished concrete by sequential mechanical abrasion of the concrete itself. The concrete polishing industry's own definitions also recognize burnished floors whose gloss can come partly from "waxes or resins." Acrylic-sealed decorative concrete is a removable-film floor: the ASCC Decorative Concrete Council's sealer guide describes a "sacrificial coating" of finish or wax over the sealer, and expects the sealer itself to wear and eventually need reapplication. Epoxy and urethane resinous floors are their own wear surface. Shine alone doesn't say which one you have, whether the floor is a lobby or a dealership showroom.

On polished concrete, Prosoco and Ameripolish tell owners not to apply floor wax or polish. Prosoco's maintenance manual for its systems says never to use acidic or alkaline cleaners and warns that acids etch concrete; W. R. Meadows excludes strippers, waxes and acidic materials from cleaners for its system. Prosoco also says its protective treatments can be reapplied without stripping away the old coat. Because a polished floor's gloss comes from abrading the concrete itself, etching or scratching is corrected by abrading it again, which is restoration work.

On resinous floors, Sherwin-Williams says cleaning and sanitizing chemicals need to be checked for compatibility with the floor before use.

Porcelain and ceramic tile

Florida Tile says porcelain typically needs no sealer, wax or surface coating, and that such coatings can work against maintenance and reduce slip resistance. The Tile Council of North America warns that acid cleaning of cement grout is not recommended by grout manufacturers and can end in regrouting, and Daltile strongly cautions against acid-based or solvent-based chemicals on fully polished porcelain, which "may damage the tile."

Vinyl and asphalt flooring installed no later than 1980

OSHA requires asphalt and vinyl flooring installed no later than 1980 to be treated as asbestos-containing (29 CFR 1910.1001(j)(2)) unless the building owner or employer demonstrates otherwise through a determination by an industrial hygienist (1910.1001(j)(8)(iii)). A determination that rules it out has to cover the associated mastic and backing as well as the flooring. Appearance and estimated age do not settle it. Building owners must determine where asbestos-containing material is in the building, keep those records, and tell the employers of anyone doing housekeeping in those areas (1910.1001(j)(3)). For routine care, OSHA's 1999 interpretation says stripping or buffing this flooring "usually comes under the scope of the General Industry Asbestos Standard." In New Jersey, federal OSHA standards apply to private-sector employers; the state's PEOSH program covers state and local government workers.

Under 29 CFR 1910.1001(k)(7):

"Sanding of asbestos-containing floor material is prohibited."

"Stripping of finishes shall be conducted using low abrasion pads at speeds lower than 300 rpm and wet methods."

"Burnishing or dry buffing may be performed only on asbestos-containing flooring which has sufficient finish so that the pad cannot contact the asbestos-containing material."

The construction standard carries parallel limits (29 CFR 1926.1101(l)(3)). Stripping is restricted, not banned. On these floors the finish is doing two jobs: it is the wear layer, and it is what keeps a burnishing pad off the tile.

Four things to settle in writing before a program is quoted

Before approving or re-scoping a floor care program, it helps to have these on paper:

1. What the floor is. Product or system name; for terrazzo, binder and coating; for concrete, which of the four kinds; for resilient flooring, whether it was installed no later than 1980 and what the owner's records say.
2. Whether it should carry finish at all. If it already does, whether that was the manufacturer's design or a later choice, and who answers for performance now.
3. The manufacturer's maintenance guide, kept with the scope. RFCI puts it in one line: "To maintain manufacturers' warranties, follow manufacturers' recommendations."
4. A test area for anything still uncertain, out of traffic, before a new chemistry or pad touches the main floor.

Most of the program follows from the first item. Our floor care page asks for "the square footage and the floor type by form or phone"; if the records give you the product or system name, include it. You can request a written quote here.
