Topcoats are a high priority for disclosure and hazard avoidance through green chemistry solutions. Given the widespread presence of topcoats and nanomaterials in resilient and wood flooring and ceramic tiles, it is not possible for consumers to avoid them at this time. The federal agency is concerned that, “such release of the nanosize material is potentially harmful to the occupants, particularly children who typically experience greater exposure to substances deposited at floor level.” The National Institute for Standards and Technology (NIST) has raised concern that “substantial” amounts of nanomaterials in topcoats may be released via repeated mechanical forces such as walking on, mopping, and polishing floors. However, some products include nanomaterials in topcoats, and these may be a concern for residents as well. The primary health concern stemming from these coatings is for workers who would be exposed to the coating while it was wet in the factory. While some ingredients in topcoats (polyurethane or epoxy-based resin hardened with aluminum oxide and exposure to ultraviolet light) may have hazards throughout their life cycle, we have not considered their hazard contribution to the ranking of the flooring material itself because the topcoat is so prevalent across product types. Many flooring materials are manufactured with a protective topcoat, a standard practice in the industry. Refer to the Flooring Installation Hazard Spectrum for guidance.

The spectrum excludes adhesives which may be required to install the products. The Flooring Products spectrum encompasses a wide variety of flooring options, including resilient, ceramic tile, wood, and carpet.
