# Roll Coating: Building Code Definition > How the IFC 2009 define roll coating, where the wording differs, and which chapters depend on the term. - Canonical: https://harth.build/resources/glossary/roll-coating/ - Last updated: 2026-09-07 - Data source: Definitions quoted from the 2009 International Codes as transcribed in this site's building-codes collection, with the source chapter linked for each quotation. Usage counts are computed over the chapters hosted here, one copy per code. The [ICC code library](https://codes.iccsafe.org/codes) publishes the current model text and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) show which edition a jurisdiction has adopted; those sources control. ## Key facts | Fact | Value | | --- | --- | | Defined in | IFC 2009 (2009 editions transcribed in this corpus) | | Primary source | IFC 2009 Flammable Finishes (model text, not a jurisdiction's adopted text) | | Chapters using the term | 2 (counted across the codes hosted here) | | Wording identical across codes | Single code (compare before citing one code's wording under another) | ## Direct answer Roll coating is a defined term in the International Fire Code (IFC) 2009, in Flammable Finishes. The code's own words are: “The process of coating, spreading and impregnating fabrics, paper or other materials as they are passed directly through a tank or trough containing flammable or combustible liquids, or over the surface of a roller revolving partially submerged in a flammable or combustible liquid.” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 2 chapters of this corpus, most often in Definitions (IFC 2009), Flammable Finishes (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. *Content and cited inputs reviewed by [Scott Barrington](https://nz.linkedin.com/in/barrington), Harth founder and architectural technology specialist · Published 2026-09-07 · Updated 2026-09-07.* ## What does this term mean? **Roll Coating** — IFC 2009, Flammable Finishes: > The process of coating, spreading and impregnating fabrics, paper or other materials as they are passed directly through a tank or trough containing flammable or combustible liquids, or over the surface of a roller revolving partially submerged in a flammable or combustible liquid. ![Labeled code-term definition diagram: Roll Coating: Building Code Definition](https://efwwel0vyt9vy5so.public.blob.vercel-storage.com/images/glossary/roll-coating/diagram-1344.webp) *How the IFC 2009 define roll coating, where the wording differs, and which chapters depend on the term.* ## What must be verified before using this guidance? **Roll Coating** is defined once in this corpus, in the [Flammable Finishes](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/flammable-finishes.md) chapter of the International Fire Code (IFC) 2009: > The process of coating, spreading and impregnating fabrics, paper or other materials as they are passed directly through a tank or trough containing flammable or combustible liquids, or over the surface of a roller revolving partially submerged in a flammable or combustible liquid. ## Where roll coating is used in the code The term appears in 2 chapters of the 2009 I-Codes hosted here. The chapters that lean on it hardest are the ones to read next. | Chapter | Code | Mentions | | --- | --- | --- | | [Definitions](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/definitions.md) | IFC 2009 | 1 | | [Flammable Finishes](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/flammable-finishes.md) | IFC 2009 | 1 | ## The terms roll coating is built out of The definition above leans on 3 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what roll coating covers: - **[Combustible Liquids](https://harth.build/resources/glossary/combustible-liquids.md)** — IMC 2009: Any liquids having a flash point at or above 100°F (38°C), and that are divided into the following classifications: - **[Combustible Liquid](https://harth.build/resources/glossary/combustible-liquid.md)** — IBC 2009: A liquid having a closed cup flash point at or above 100°F (38°C). - **[Liquid](https://harth.build/resources/glossary/liquid.md)** — IBC 2009: A material that has a melting point that is equal to or less than 68°F (20°C) and a boiling point that is greater than 68°F (20°C) at 14.7 pounds per square inch absolute (psia) (101 kPa). ## Roll Coating: what to open, and in what order Every row is a document this term depends on.

The International Fire Code (IFC) 2009 defines it in Flammable Finishes as: “The process of coating, spreading and impregnating fabrics, paper or other materials as they are passed directly through a tank or trough containing flammable or combustible liquids, or over the surface of a roller revolving partially submerged in a flammable or combustible liquid.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally. ### Which parts of the code depend on roll coating? In this corpus the term is used across 2 chapters, led by Definitions in the IFC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own. ### What is roll coating and how is it performed? In the 2009 I-Codes hosted here it is a defined term rather than a description. The IFC 2009 states, in Flammable Finishes: “The process of coating, spreading and impregnating fabrics, paper or other materials as they are passed directly through a tank or trough containing flammable or combustible liquids, or over the surface of a roller revolving partially submerged in a flammable or combustible liquid.” It is defined in IFC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fglossary%2Froll-coating%2F - View this page in a browser: https://harth.build/resources/glossary/roll-coating/ - All resources for agents: https://harth.build/llms.txt
