California CSLB Epoxy Flooring and Decorative Concrete Coating Contractor D-42 / C-61 Attorney Fee Petition Mechanics: Tyler Odyssey Civil Complaint Date as Primary Welch Anchor, CSLB License Check (D-42 / C-61) as Secondary Anchor (THE ONLY D-42 Epoxy Flooring Page in This Series — DISTINCT FROM D-6 Concrete Related Services and D-5 Flooring and Floor Covering — ONLY Page With ASTM C1583 Standard Test Method for Tensile Strength of Concrete Surfaces Advisory [THE ONLY PAGE in the Fee-Petition-Mechanics Series With an ASTM C1583 Advisory — PURE KETCHUM] and SSPC-SP 13 / NACE No. 6 Surface Preparation of Concrete Advisory [THE ONLY PAGE in the Fee-Petition-Mechanics Series With an SSPC-SP 13 / NACE No. 6 Advisory — PURE KETCHUM]; CDPH Food Facility Permit Health & Safety Code § 114149 as Second Institutional Anchor; Epoxy Delamination CDPH Permit Suspension Restaurant Closure / Moisture Vapor Blistering Warehouse Floor Teardown / Solvent Ignition Fire Three-Track Harm; Bus. & Prof. Code § 7031(b) Disgorgement), CLRA § 1780 Mandatory Attorney Fees

Statutory Framework: Bus. & Prof. Code § 7028, D-42 / C-61 Epoxy Flooring and Decorative Concrete Coating, ASTM C1583 Advisory, SSPC-SP 13 Advisory, CDPH Floor Inspection Advisory, § 7031(b) Disgorgement, and CLRA § 1780 Mandatory Attorney Fees

California Business and Professions Code § 7028 prohibits unlicensed contracting. The CSLB D-42 (Epoxy Flooring and Decorative Concrete Coating) limited specialty designation under C-61 authorizes: application of 100% solids, solvent-based, or water-based epoxy coating systems to existing hardened concrete slab surfaces; application of polyurethane topcoat sealers over epoxy base coats; application of decorative concrete overlays including microtoppings, skim coats, and stampable overlays over existing slabs; polished concrete grinding and densifier application for commercial floor polishing; application of moisture-mitigation primer systems (epoxy MV or polyurethane moisture-mitigation primer) on slabs with elevated MVER; and crack repair with epoxy injection or flexible polyurethane sealant prior to coating application. D-42 does not cover: placement of new concrete slabs (requires D-6 or C-8); installation of ceramic or quarry tile over concrete substrate (requires D-37 or C-54); installation of resilient LVT or hardwood flooring over concrete substrate (requires D-5); structural concrete repair or carbon fiber strengthening (requires C-8 or C-61/D-6); or plumbing trench cutting and repair in concrete slabs (requires C-36).

ASTM C1583 Standard Test Method for Tensile Strength of Concrete Surfaces and the Bond Strength or Tensile Strength of Concrete Repair and Overlay Materials by Direct Tension — Pull-Off Method (published by ASTM International) is a private technical standard — NOT a California statute, NOT California administrative code, NOT a federal regulation creating mandatory civil attorney fees. ASTM C1583 specifies: minimum concrete surface tensile strength required before epoxy coating application — general industrial: 200 psi; commercial kitchen: 250 psi; high-traffic industrial: 300 psi; pull-off test procedure: portable adhesion tester (PAT) with minimum 40-mm diameter steel dolly, bonded to the concrete surface using two-part epoxy adhesive cured for minimum 24 hours, core cut around the perimeter of the dolly to release the test area from the surrounding substrate, load applied perpendicular to the surface at a rate of 15–25 psi/second until failure; failure mode classification: Type A — cohesive failure within the concrete substrate (acceptable — confirms concrete is stronger than the adhesive bond); Type B — adhesive failure at the coating/concrete interface (unacceptable — indicates surface contamination, laitance, or inadequate preparation); minimum three test locations per 500 square feet of planned coating area; ASTM C1583 pull-off testing is a private ASTM International test procedure — not a California statutory requirement as a standalone standard. PURE KETCHUM: ASTM C1583 is a private ASTM International standard — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism for persons harmed by unlicensed California D-42/C-61 epoxy flooring contractors.

SSPC-SP 13 / NACE No. 6 Surface Preparation of Concrete (published jointly by SSPC — Society for Protective Coatings — and NACE International, now merged as AMPP — Association for Materials Protection and Performance) is a private joint technical standard — NOT a California statute, NOT California administrative code, NOT a federal regulation. SSPC-SP 13 / NACE No. 6 specifies: concrete surface preparation requirements for protective coating application; Method 1 (dry abrasive blasting): achieves minimum Concrete Surface Profile CSP-3 per ICRI 310.2R; Method 2 (water jetting at high or ultra-high pressure): achieves minimum CSP-3; Method 3 (mechanical preparation — scarification, diamond grinding, or shotblasting): achieves minimum CSP-3; oil, grease, and form-release agent removal required before any mechanical preparation method; moisture vapor emission rate (MVER) testing required per ASTM F1869 (calcium chloride method) or ASTM F2170 (in-situ relative humidity probe): most standard epoxy systems require MVER ≤ 3 lbs/1,000 sq ft/24 hrs; elevated MVER requires moisture-mitigation primer system before topcoat application; CSP (Concrete Surface Profile) scale from CSP-1 (smooth, lightly etched) to CSP-9 (heavily scarified); minimum CSP-3 (equivalent to medium sandblast) is required for standard epoxy systems to achieve adequate mechanical adhesion; without CSP-3 profile, the epoxy coating relies on chemical adhesion alone, which is insufficient for commercial and industrial traffic loads. PURE KETCHUM: SSPC-SP 13 / NACE No. 6 is a private joint standard published by SSPC and NACE International (AMPP) — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism; surface preparation deficiencies generating coating failures and CDPH violations are recoverable as CLRA actual damages.

Primary Welch Anchor: Tyler Odyssey Civil Complaint Filing Date

The Tyler Odyssey civil complaint filing date is the primary Welch temporal anchor for D-42 epoxy flooring matters. The attorney files after confirming CSLB C-61/D-42 license status, retaining a NACE-certified coatings inspector to perform ASTM C1583 pull-off tests and document SSPC-SP 13 surface profile deficiency, obtaining CDPH food facility permit records under H&S Code § 114149, and serving the CLRA § 1782 demand. The CSLB D-42/C-61 License Check date is the secondary Welch anchor. Ketchum v. Moses 24 Cal.4th 1122 (2001); PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000).

Secondary Anchor: CSLB License Check (D-42 / C-61 Epoxy Flooring and Decorative Concrete Coating) — THE ONLY D-42 Specialty Anchor in the Fee-Petition-Mechanics Series

The CSLB License Check must confirm the C-61/D-42 Epoxy Flooring and Decorative Concrete Coating limited specialty designation — distinct from D-6 (Concrete Related Services, which covers structural slab placement), D-5 (Flooring and Floor Covering, which covers resilient and wood flooring over substrate), and D-37 (Specialty Tile and Stone, which covers ceramic and stone tile installation). Three scenarios generate § 7028 liability: (a) no CSLB license at all; (b) expired, suspended, or revoked C-61/D-42 license; (c) a general handyman or maintenance contractor who applies epoxy coating to a garage or commercial floor without holding the D-42 limited specialty. This page is THE ONLY D-42 Epoxy Flooring specialty anchor in the fee-petition-mechanics series.

Billing Gap 1 — CSLB D-42/C-61 License Check, ASTM C1583 Pull-Off Test Documentation, SSPC-SP 13 Surface Profile and MVER Test Data Review, CDPH Permit Records, and § 1782 Demand (5.25 hrs/yr = $1,575–$2,625)

The first billing gap covers pre-complaint advisory for D-42 epoxy flooring matters.

• Searching CSLB License Check for C-61/D-42 designation and establishing the secondary Welch anchor: confirming D-42 limited specialty presence or absence; evaluating D-6 distinction (structural slab vs. surface coating) and D-5 distinction (resilient flooring over substrate vs. chemical coating on concrete); confirming license status, bond, and workers compensation insurance.
• Retaining NACE-certified coatings inspector for ASTM C1583 pull-off test and failure mode analysis: CIP Level II or III inspector performs PAT pull-off tests per ASTM C1583 — minimum three test locations per 500 sq ft of delaminated area; documents failure mode as Type B (adhesive failure — surface contamination) versus Type A (cohesive failure — acceptable); records load at failure and compares to 250 psi commercial kitchen minimum; photographs delaminated zones with measurement scale.
• Reviewing SSPC-SP 13 surface profile and MVER test records — second private standard advisory: inspector performs ICRI 310.2R comparator chip assessment of concrete surface profile — documents CSP-1 smooth grind versus required CSP-3 minimum; performs ASTM F1869 calcium chloride MVER test on delaminated and adjacent areas — documents MVER measurement against 3-lb system maximum; reviews unlicensed contractor's project file for absence of surface profile records, MVER test results, and degreasing documentation.
• Obtaining CDPH food facility permit records under H&S Code § 114149 — second institutional anchor: CDPH environmental health department inspection reports; violation notices identifying delaminated floor and standing water conditions; permit suspension order and reinstatement requirements; closure dates and re-opening date for lost revenue calculation.
• Serving CLRA § 1782 demand incorporating ASTM C1583 and SSPC-SP 13 advisory analysis: demand specifies D-42 unlicensed contracting, identifies three harm tracks, demands disgorgement under § 7031(b), and specifies CLRA § 1780 mandatory attorney fees.

Billing Gap 2 — Active Litigation: NACE Coatings Inspector Expert, CDPH Permit Suspension Revenue Analysis, Warehouse Floor Teardown Cost Quantification, Fire Cause and Origin Expert, and Three-Track Damage Computation (4.00 hrs/yr = $1,200–$2,000)

The second billing gap covers expert coordination across the three D-42 harm tracks.

• NACE coatings inspector expert opinion for Track 1 CDPH permit suspension: CIP inspector provides written expert opinion that the unlicensed D-42 contractor's failure to perform ASTM C1583 pull-off testing and failure to remove oil contamination per SSPC-SP 13 caused the Type B adhesive failure and subsequent delamination; quantifies cost of properly prepared and applied commercial kitchen epoxy system as replacement damages; documents 21 days of CDPH closure, daily revenue figure from prior period revenue, and total lost revenue of $67,000.
• Moisture vapor and surface profile analysis for Track 2 warehouse floor blistering: inspector provides expert opinion on CSP-1 vs. CSP-3 deficiency; ASTM F1869 MVER documentation; quantifies total teardown cost — delaminated coating removal (diamond-cup grinder and scraper), shotblasting to CSP-3, MVER retest confirmation, moisture-mitigation primer application, full epoxy system re-application across 4,800 sq ft; contractor provides bid for complete redo as damages evidence; total $48,000 replacement cost analysis.
• Fire cause and origin expert for Track 3 solvent ignition: licensed fire investigator (NFPA 921-trained) documents cause and origin — solvent vapor accumulation from VOC 340 g/L solvent-based epoxy primer in enclosed below-grade garage; identification of spark-producing angle grinder as ignition source; Cal/OSHA 8 CCR § 5415 flammable liquids violations as contributing factors; quantifies $95,000 structure and vehicle damage from fire damage assessment records and insurance adjuster report.
• Settlement valuation incorporating all three harm tracks and CLRA § 1780 mandatory attorney fees: D-42 three-track settlement demand integrates CDPH permit suspension lost revenue, warehouse blistering teardown cost, and solvent fire property damage with CLRA mandatory attorney fees.
