How to Use This Concrete Coating Resource
The National Concrete Coating Authority functions as a structured reference directory for the concrete coating service sector across the United States. This page describes how the site's content is organized, what falls within and outside its scope, how to locate specific topics, and what standards govern factual claims published here. Professionals, property owners, and researchers navigating the concrete coating landscape will find this reference structure relevant to qualification screening, product classification, and regulatory orientation.
How information is organized
Content on this site is divided into three functional layers: reference material describing the concrete coating service sector, classification frameworks for coating types and application contexts, and a Concrete Coating Listings directory of service providers organized by geography and specialization.
Reference material covers the regulatory and standards environment governing concrete coating work. Named governing bodies include the Occupational Safety and Health Administration (OSHA) — which sets exposure limits and ventilation requirements under 29 C.F.R. Part 1910 for industrial coating environments — and ASTM International, whose standards such as ASTM D4541 (tensile adhesion testing) and ASTM D7234 (pull-off strength of coatings) define performance benchmarks used in commercial and industrial specifications. The International Concrete Repair Institute (ICRI) publishes surface preparation guidelines, including ICRI 310.2R, which classifies Concrete Surface Profile (CSP) levels from CSP 1 through CSP 10.
Classification within the directory separates concrete coating work into four primary categories:
- Decorative coatings — epoxy, polyurea, and polyaspartic systems applied in residential and commercial settings for aesthetic and light-duty protective purposes
- Industrial protective coatings — high-build systems specified for chemical resistance, heavy traffic, or containment environments, governed by specifications such as SSPC-SP 13/NACE 6 for surface preparation
- Waterproofing and sealers — penetrating or film-forming systems applied to below-grade or exterior flatwork
- Structural rehabilitation coatings — overlays and bonding agents used in repair scopes governed by ACI 546 (Concrete Repair Guide)
Each category carries distinct surface preparation requirements, cure schedules, and inspection criteria. Decorative residential systems and industrial containment coatings, for example, diverge sharply in film thickness tolerance — residential polyaspartic systems typically run 20–40 mils dry film thickness (DFT), while secondary containment epoxy linings may require 125 mils DFT or greater under facility-specific engineering specifications.
Limitations and scope
This site covers concrete coating as a defined service sector — not concrete construction, structural repair engineering, or general masonry. The directory purpose and scope page details these boundaries explicitly.
Geographic scope is national within the United States. Listings and regulatory references reflect US-based licensing frameworks, including state contractor licensing boards such as the California Contractors State License Board (CSLB), which classifies coating work under the C-33 (Painting and Decorating) and D-16 (Fire Protection) classifications depending on application type. Licensing requirements differ across all 50 states; no single federal licensing standard exists for concrete coating contractors.
Content does not constitute legal advice, engineering specifications, or product endorsement. No warranty is implied regarding contractor performance, product efficacy, or compliance outcomes. Permitting requirements for coating projects — which may arise under local building codes when work affects occupied spaces, containment integrity, or VOC emission thresholds regulated by EPA National Emission Standards — are noted as reference frames, not as project-specific guidance.
How to find specific topics
The site's primary navigation runs through the Concrete Coating Listings for service provider location and through the reference section for standards, classification, and regulatory orientation.
To locate a contractor by coating type or region, use the listings directory filtered by state and application category. To locate regulatory standards relevant to a specific project context — such as OSHA ventilation requirements for solvent-borne coatings or EPA Method 24 VOC testing protocols — consult the reference section organized by regulatory body and coating system type.

How content is verified
Every quantified claim, regulatory citation, and standards reference published on this site traces to a named public source. Specific figures — film thickness ranges, CSP classification scales, regulatory citation numbers — are drawn from documents published by ASTM International, ACI (American Concrete Institute), ICRI, OSHA, and EPA. No statistics are fabricated or attributed to unnamed industry averages.
Primary reference authorities used across this site include:
- ASTM International — coating performance test methods including ASTM D4541 and ASTM D7234, surface profile standards, and chemical resistance protocols
- American Concrete Institute (ACI) — ACI 308 (external curing), ACI 546 (concrete repair), and related committee documents available at concrete.org
- ICRI (International Concrete Repair Institute) — surface preparation guidelines and CSP classification scales
- OSHA (29 C.F.R. Part 1910 and Part 1926) — worker safety standards applicable to coating application environments, including respiratory protection and confined space protocols
- EPA — VOC regulations and National Emission Standards for Hazardous Air Pollutants (NESHAPs) relevant to architectural and industrial coating products
Where a named standard has been revised, the most recent edition cited is identified by publication year or revision number inline. Where content reflects a regulatory requirement that varies by jurisdiction, that variability is stated explicitly rather than resolved to a single rule. Listings data is submitted by contractors and is not independently audited for licensure status; readers are directed to verify active licensing through the relevant state contractor licensing board prior to engagement.
