+category: Architectural / Finishes
+toc_depth: 3
+description: >
+ When to use: thin-film to medium-build two-component epoxy floor coatings (100% solids, solvent-borne, or waterborne) applied by roller or squeegee over prepared concrete slabs for protection and appearance in commercial, institutional, and light-to-medium duty industrial spaces — back-of-house corridors, mechanical and electrical rooms, storage and warehouse floors, school gymnasiums and corridors, light-duty institutional kitchens, light manufacturing, and pedestrian parking decks; dry film thicknesses from roughly 3 mil (waterborne sealer) to 30 mil (high-build or broadcast decorative systems); single-coat sealers, two-coat base/topcoat systems, vinyl-chip and color-quartz broadcast systems, and aliphatic polyurethane or polyaspartic topcoats over epoxy.
+ Not intended for: full resinous floor toppings — self-leveling slurries, sand/quartz mortar beds, cementitious urethane, MMA, and wearing surfaces exceeding 30 mil (see [[sync/resinous-flooring]]); thin-film coatings on walls, masonry, structural steel, and secondary containment (see [[sync/high-performance-coatings]]); polished, ground, or chemically sealed bare concrete without an applied resin film (see [[sync/polished-concrete]]); resilient sheet/tile/LVT/VCT/rubber/linoleum, terrazzo, ceramic and porcelain tile, carpet, vehicular traffic-bearing deck waterproofing membranes; and concrete slab design, placement, curing, and under-slab vapor retarder (see [[sync/cast-in-place-concrete]]).

+
+# Scope {toc}
+
+## This standard covers two-component epoxy floor coating systems applied as a thin-film to medium-build finish over prepared cast-in-place concrete slabs for traffic protection, chemical and abrasion resistance, and appearance. {note}
+
+## It addresses 100% solids, solvent-borne, and waterborne (water-reducible) epoxy chemistries applied by roller or squeegee, in single-coat sealer, two-coat base/topcoat, and broadcast decorative (vinyl-chip or color-quartz) configurations, at dry film thicknesses from approximately 3 mil to 30 mil. {note}
+
+## Surface preparation, concrete moisture acceptance, surface profile, slip-resistance finishing, and aliphatic topcoats applied over the epoxy base are within scope. {note}
+
+### This standard fills the practical middle ground between two sibling standards: [[sync/resinous-flooring]] covers the full spectrum of fluid-applied chemistries — self-leveling slurries, broadcast mortar beds, cementitious urethane, MMA, and heavy-duty wearing surfaces exceeding 30 mil — and is the governing standard for heavy industrial, food, and pharmaceutical environments; [[sync/high-performance-coatings]] covers the same epoxy and polyurethane chemistries applied to vertical, wall, structural-steel, and secondary-containment substrates; and [[sync/polished-concrete]] covers bare concrete surfaces that are mechanically polished, ground, or chemically densified without an applied resin film. {note}
+
+## The following are outside the scope of this standard and are governed elsewhere. {note}
+
+### Outside this standard: {note}
+- Full resinous floor toppings — self-leveling slurries, sand/quartz mortar beds, cementitious urethane, MMA, and broadcast wearing surfaces exceeding 30 mil: see [[sync/resinous-flooring]].
+- Thin-film protective coatings on concrete walls, masonry, structural steel, and secondary containment: see [[sync/high-performance-coatings]].
+- Polished, ground, or chemically densified bare concrete with no applied resin film: see [[sync/polished-concrete]].
+- Resilient sheet, tile, LVT, VCT, rubber, and linoleum floor coverings: outside this standard.
+- Cementitious and epoxy-matrix terrazzo: outside this standard.
+- Ceramic and porcelain tile: outside this standard.
+- Vehicular traffic-bearing deck waterproofing membranes on parking structures: outside this standard.
+- Carpet and textile floor coverings: outside this standard.
+- Concrete slab design, placement, curing, and the under-slab vapor retarder: see [[sync/cast-in-place-concrete]].
+
+## System Selection {toc}
+
+### The system type, total dry film thickness, decorative treatment, topcoat chemistry, and slip-resistance finish shall be selected to suit the service, traffic, chemical exposure, and appearance requirements of each area.
+
+### The system selection shall be coordinated with the room finish schedule.
+
+### Resin solids content and system type, total dry film thickness, and decorative treatment shall be as selected below.
+
+```datasheet
+label: Resin solids content / system type
+type: radio
+options:
+ - 100% solids (highest durability, zero VOC, ≥ 8 mil DFT)
+ - Solvent-borne (good penetration, VOC-regulated)
+ - Waterborne / water-reducible (low VOC, light-duty, 3-6 mil DFT)
+default: 100% solids (highest durability, zero VOC, ≥ 8 mil DFT)
+```

+type: radio
+options:
+ - Solid color (base + topcoat only)
+ - Vinyl chip / color flake broadcast
+ - Color-quartz broadcast
+ - Metallic epoxy
+default: Solid color (base + topcoat only)
+```
+
+### Topcoat chemistry shall be selected for the area's UV exposure and color-stability requirements; epoxy topcoats shall be used only in interior, UV-free back-of-house spaces.
+
+```datasheet
+label: Topcoat chemistry
+type: radio
+options:
+ - Aliphatic polyurethane (best UV and chemical resistance)
+ - Polyaspartic (fast cure, UV stable)
+ - Epoxy topcoat (interior / back-of-house only — yellows under UV)
+default: Aliphatic polyurethane (best UV and chemical resistance)
+```
+
+### The slip-resistance finish shall be selected for each area and shall meet the coefficient-of-friction requirements of the Slip Resistance section.
+
+```datasheet
+label: Slip-resistance treatment
+type: radio
+options:
+ - Smooth / gloss (dry pedestrian areas only)
+ - Aluminum-oxide grit broadcast into final coat
+ - Polymer-bead grip additive in final coat
+ - Fine silica sand broadcast
+default: Smooth / gloss (dry pedestrian areas only)
+```
+
+### Primer, body coat, and topcoat shall be products of a single manufacturer's compatible system; components from different manufacturers shall not be combined.
+
+### A single-manufacturer system requirement preserves both intercoat compatibility and the manufacturer's system warranty; mixing a primer from one source with a topcoat from another voids both and invites substitution RFIs from the flooring contractor. {note}

+```
+
+# Quality Assurance {toc}
+
+## The applicator shall be trained or certified by the coating system manufacturer and shall have completed projects of comparable scope and system type.
+
+## A single manufacturer shall furnish the primer, body coat, topcoat, and aggregates as a warranted system.
+
+## Mockup {toc}
+
+### The Contractor shall prepare a job-site mockup of each system, including surface preparation, on an area of the actual slab of not less than 100 sf (9.3 m²) before beginning general application.
+
+### The mockup shall include the full sequence — surface profile, primer, body coat, broadcast (if any), and topcoat — at the specified DFT and finish.
+
+### The approved mockup shall establish the standard of acceptable surface profile, appearance, color, gloss, and slip resistance for the work and shall be maintained for comparison through completion.
+
+### The mockup may remain as part of the finished work if it is indistinguishable from surrounding application and is accepted by the Architect. {note}
+
+## Pre-Installation Conference {toc}
+
+### A pre-installation conference shall be held before surface preparation to review substrate condition, moisture test results, curing compound removal, surface profile target, environmental limits, and the application and recoat schedule.
+
+### The conference is the point at which the flooring contractor, general contractor, and manufacturer's representative reconcile the concrete's actual condition against the system's requirements; most epoxy floor failures trace to a substrate condition that was knowable and ignored at this stage. {note}
+
+# Environmental and Service Conditions {toc}
+
+## Concrete Substrate Condition {toc}
+
+### The concrete substrate shall have a minimum compressive strength of 3000 psi (20.7 MPa) and a minimum surface tensile strength of 150 psi (1.0 MPa) before coating application.
+
+### A surface tensile strength of at least 150 psi is the floor beneath the 200 psi coating pull-off requirement: the coating cannot adhere more strongly than the concrete it is bonded to, so weak, laitance-bearing, or friable surface concrete must be removed during preparation. {note}
+
+### The substrate shall be sound, fully cured, and free of laitance, dust, oil, grease, curing compound, sealers, and other bond-inhibiting contaminants before coating.
+
+### Voids, cracks, spalls, and surface defects shall be patched with a compatible repair material and cured before coating application.
+
+### Epoxy floor coatings are a finish, not a substrate repair medium; thin-film coatings bridge but do not fill defects and will telegraph cracks, voids, and unevenness into the finished surface. {note}
+
+## Concrete Moisture {toc}
+
+### Concrete moisture shall be tested and shall meet the limits below before coating; the test method and acceptance limit depend on the selected primer.
+
+### Standard epoxy primers shall not be applied where the moisture vapor emission rate exceeds 3 lb/1000 sf/24 hr (ASTM F1869) or the in-situ relative humidity exceeds 75% (ASTM F2170).
+
+### Moisture-tolerant primers may be used where the MVER is up to 5-8 lb/1000 sf/24 hr or the in-situ RH is up to 80-85%, in accordance with the primer manufacturer's published limits.
+
+### A moisture-tolerant or moisture-mitigating primer shall be specified for on-grade and below-grade slabs and for slabs less than 6 months old.
+
+### Osmotic blistering and delamination from unmitigated slab moisture are the single most common field failure of epoxy floor coatings; moisture testing is not optional and slab age alone is never a substitute for a test result. {note}

+
+## Application Environment {toc}
+
+### Substrate and ambient air temperature shall be maintained between 50 °F and 90 °F (10 °C and 32 °C) during application and through the manufacturer's stated cure period.
+
+### Substrate temperature shall be at least 5 °F (3 °C) above the dew point at the time of each coat.
+
+### Coating shall not be applied when rain, condensation, or surface dampness is present or imminent.
+
+### Application below 50 °F or within 5 °F of the dew point causes amine blush and adhesion failure; these lower limits are hard stops, not guidelines. {note}
+
+### The Contractor shall document ambient and substrate temperature, dew point, and relative humidity before each coat.

+
+# Performance Requirements {toc}
+
+## The installed coating system shall meet the following performance requirements for the selected duty class. {note}
+
+## Adhesion {toc}
+
+### Field pull-off adhesion (ASTM D4541) shall be a minimum of 200 psi (1.4 MPa) at 7-day cure, with no failure at the coating-to-concrete interface below that value.
+
+### Where the substrate fails cohesively in the concrete below 200 psi, the result documents the substrate's tensile limit rather than a coating defect. {note}
+
+### A cohesive substrate failure shall be reported as such in the test record.

+
+## Abrasion Resistance {toc}
+
+### Abrasion resistance (ASTM D4060, Taber CS-17 wheel, 1000 g load) shall not exceed 70 mg loss per 1000 cycles for standard-duty coatings and 35 mg loss per 1000 cycles for heavy-duty coatings.

+
+## Slip Resistance {toc}
+
+### Smooth, high-gloss epoxy floors become hazardous when wet or contaminated; pairing a finish selection with an explicit COF requirement is the mechanism that enforces accountability for slip resistance. {note}
+
+### Every finish specification shall be paired with a coefficient-of-friction requirement.
+
+### Wet or grease-prone areas shall receive a non-skid additive or aggregate broadcast into the final coat.
+
+### The dry static coefficient of friction (ASTM D2047, James Machine) shall be a minimum of 0.5 for pedestrian floor areas.
+
+### The wet dynamic coefficient of friction (ANSI A326.3) shall be a minimum of 0.42 for level interior areas subject to wet or intermittently wet conditions.
+
+### Kitchens, restrooms, wash-down areas, and loading and receiving areas shall receive a non-skid aggregate or polymer grip additive broadcast into the final coat.
+
+```datasheet

+
+## Gloss {toc}
+
+### Specular gloss (ASTM D523, 60° geometry) shall meet the level selected for each area, coordinated with the reflected ceiling plan light-reflectance values and the maintenance and safety program.
+
+```datasheet

+default: Semi-gloss (35-70 GU)
+```
+
+## Surface Burning and VOC {toc}
+
+### Where the coating is installed in egress corridors and exit-access paths, its surface burning characteristics (ASTM E84) shall yield a flame spread index of not more than 75 and a smoke developed index of not more than 450.
+
+### The coating system VOC content shall not exceed the limit of the applicable regional air district (for example, the CARB Architectural Coatings Rule floor-coating limit of 100 g/L); 100% solids systems are effectively 0 g/L and exempt.
+
+### Confirm the governing VOC authority early — SCAQMD, OTC states, and CARB differ — because a solvent-borne system that is compliant in one jurisdiction may be prohibited in another and forces a chemistry change late in the project. {note}
+
+```datasheet

+```
+
+# Materials {toc}
+
+## Primer {toc}
+
+### The primer shall be a two-component epoxy compatible with the body coat and selected for the substrate's tested moisture condition per the Concrete Moisture section.
+
+### Where the slab moisture exceeds the standard-primer limits, a moisture-tolerant or moisture-mitigating primer matched to the tested MVER or RH shall be furnished.
+
+## Body Coat {toc}
+
+### The body coat shall be a two-component epoxy of the selected solids content, applied at the wet film thickness required to achieve the specified dry film thickness.
+
+### Dry film thickness, not wet film thickness, shall govern acceptance; the Contractor shall account for solids content when establishing the application rate.
+
+### A 50%-solids product applied at 10 mil WFT yields only 5 mil DFT, so specifying and measuring by DFT prevents a thin, under-built film that passes a wet-mil gauge but fails in service. {note}
+
+```datasheet

+min: 40
+max: 100
+step: 5
+default: 100
+```
+
+## Topcoat {toc}
+
+### The topcoat shall be an aliphatic polyurethane or polyaspartic where the floor receives any UV exposure, exterior light, or requires long-term color stability.
+
+### An epoxy topcoat shall be used only in interior, UV-free back-of-house spaces.
+
+### Standard epoxy yellows and chalks rapidly under UV; any space where exterior light reaches the floor — even reflected daylight near a window or overhead door — requires an aliphatic polyurethane or polyaspartic topcoat to hold color and gloss. {note}
+
+## Broadcast Aggregates and Additives {toc}
+
+### Decorative vinyl chips or color flakes, graded silica or color quartz, slip-resistant aluminum-oxide grit, and polymer grip additives shall be the manufacturer's matched components for the selected system.
+
+### Anti-static or ESD systems shall use a conductive primer and a dissipative topcoat achieving a measured surface resistance of 10⁶ to 10⁹ Ω; heavy-duty ESD flooring is outside this standard and is governed by [[sync/resinous-flooring]].
+
+```datasheet
+label: ESD surface resistance target (light-duty dissipative)

+options:
+ - "Not applicable (no ESD requirement)"
+ - "10⁶ to 10⁹ Ω (dissipative)"
+default: "Not applicable (no ESD requirement)"
+```
+
+# Surface Preparation {toc}
+
+## Mechanical Profiling {toc}
+
+### Surface preparation shall produce a concrete surface profile (CSP) per ICRI 310.2R verified against a CSP profile comparator; the work shall not be specified by description alone.
+
+### Specifying preparation as "remove laitance" or "shot blast clean" without a CSP target is ambiguous and unenforceable; the comparator gives the inspector an objective acceptance reference. {note}
+
+### Thin-film sealers below 6 mil DFT shall be prepared to a minimum CSP 2 by diamond grinding or light shot blasting.
+
+### Standard and high-build coatings at 6 mil DFT and above shall be prepared to CSP 3 by shot blasting.
+
+### Acid etching shall not be used as the sole surface preparation method, and shall not be used at all for 100% solids systems.
+
+### Acid etching produces at best a CSP 1 profile, is inadequate for any coating above 6 mil, and is prohibited by most 100% solids manufacturers; shot blasting or diamond grinding is required for an enforceable bond. {note}
+
+```datasheet
+label: Concrete surface profile (ICRI 310.2R)
+type: radio
+options:
+ - CSP 2 (diamond grinding / light shot blast — thin-film < 6 mil)

+type: radio
+options:
+ - Shot blasting (preferred for large areas)
+ - Diamond grinding
+default: Shot blasting (preferred for large areas)
+```
+
+## Curing Compound and Contaminant Removal {toc}
+
+### The Contractor shall confirm the type of any membrane-forming curing compound used on the slab and shall mechanically remove it as part of the surface preparation scope.
+
+### Membrane-forming curing compounds — sodium silicate, acrylic, or wax — contaminate the epoxy bond and shall be removed before profiling.
+
+### Chemical stripping alone shall not be relied upon where mechanical removal is required by the coating manufacturer.
+
+### A curing compound left in place is invisible after profiling but defeats adhesion across the whole floor; the removal scope must be confirmed against the slab's actual curing record, not assumed. {note}
+
+## Crack and Joint Treatment {toc}
+
+### Cracks, control joints not intended to remain visible, and surface defects shall be repaired with a compatible epoxy or polymer repair material and cured before coating.
+
+### Moving joints and isolation joints shall be honored through the coating and shall not be rigidly filled where movement is expected.
+
+# Application {toc}
+
+## Sequence and Thickness {toc}
+
+### Each coat shall be applied at the manufacturer's specified rate to achieve the cumulative dry film thickness selected in the System Selection section, verified by wet-film gauge during application and dry-film measurement after cure.
+
+### Broadcast systems shall be broadcast to rejection into the wet base coat, allowed to cure, scraped or vacuumed, and sealed with the grout and topcoat as the manufacturer directs.
+
+## Recoat Window {toc}
+
+### Each subsequent coat shall be applied within the manufacturer's maximum recoat (overcoat) window; where the window is exceeded, the prior coat shall be mechanically abraded before the next coat is applied.
+
+### Most 100% solids epoxies allow topcoating at 8-16 hours at 65 °F, with a maximum recoat window of roughly 24-48 hours; beyond that window intercoat adhesion drops sharply and the surface must be abraded to restore bond. {note}

+
+## Layout and Extents {toc}
+
+### Coating limits, color and finish changes, control-joint treatment, and transitions to adjacent flooring shall be installed at the locations and extents indicated. [[drawing: floor finish plan]]
+
+### Transitions to tile, polished concrete, or resilient flooring shall be detailed for the elevation difference created by the coating build and installed at the detailed transition. [[drawing: floor transition details]]
+
+### Epoxy coatings add 8 to 30 mil to the slab surface; at transitions the elevation step and threshold detail must be coordinated with [[sync/polished-concrete]] and [[sync/resinous-flooring]] so the finished floors meet flush or with an intended, accessible transition. {note}
+
+# Testing {toc}
+
+## Field pull-off adhesion (ASTM D4541) shall be performed at the frequency indicated, with a minimum of one test per area and one per 5000 sf, and shall meet the adhesion requirement.
+
+## Dry film thickness shall be verified after cure at representative locations in each area and shall meet the specified DFT.
+
+## Slip resistance shall be verified on the installed finish where a COF/DCOF requirement applies, by the method specified for that area.
+
+## Areas failing any acceptance test shall be repaired or recoated per the manufacturer's instructions and retested.
