Commercial & Industrial Epoxy Flooring
Epoxy is the most widely specified flooring system in commercial and industrial construction — and the most commonly misspecified. The wrong system thickness, the wrong aggregate, or a missed moisture test can mean a floor that fails in 18 months instead of lasting 20 years. DTI specifies and installs epoxy flooring systems based on your facility's actual conditions — traffic class, chemical exposure, substrate quality, and compliance requirements — before any work is priced.
Completed Projects
Nissan Dealership
Automotive dealership service areas face heavy vehicle traffic, oil and fluid exposure, and the need for a clean, professional finish that holds up under daily use. DTI installed a broadcast epoxy system in the service bay with a chemical-resistant polyurethane topcoat and anti-slip aggregate in high-traffic zones. The floor handles daily vehicle movement and fluid spills while maintaining a finished appearance appropriate for a customer-facing facility.
Travis Air Force Base
High-traffic service areas at Travis AFB required flooring upgrades to withstand constant vehicle movement, fuel and chemical exposure, and round-the-clock operational use. DTI installed a broadcast epoxy system with a chemical-resistant topcoat within a tight installation window that minimized disruption to base operations.
Epoxy System Types
Not all epoxy flooring is the same. The right system depends on what the floor needs to do.
Most common commercial & industrial system
A base coat is applied, decorative flake or quartz aggregate is broadcast into the wet epoxy, and a clear polyurethane or polyaspartic topcoat seals the surface. The aggregate layer adds texture, slip resistance, and thickness.
Seamless, high-gloss surface
A high-build liquid epoxy that flows to a smooth, flat finish. Applied at thicknesses from 1/8" to 1/4" depending on specification. Produces a seamless, high-gloss surface with no aggregate texture.
Heaviest-duty system available
Mixed with graded sand or aggregate to create a thick, impact-resistant surface. Applied at 1/4" to 1/2" thickness. Handles the heaviest forklift loads, dropped equipment, and severe chemical exposure.
10–20 mils dry film thickness
A surface-applied epoxy coating providing basic protection and a clean finish for substrates in good condition that don't require a heavy system.
Static-control upgrade
Standard epoxy systems can be upgraded with a conductive primer and ESD topcoat for environments requiring static control. See our ESD Flooring page for full specifications.
Chemical Resistance
Epoxy systems vary significantly in their chemical resistance. The base epoxy layer provides general resistance — the topcoat determines the system's actual chemical performance. DTI specifies topcoats by your facility's specific chemical inventory:
General chemical resistance, UV stable, good abrasion resistance. Standard specification for most commercial and industrial applications.
Fast cure (return to service in 4–6 hours), excellent UV resistance, high abrasion resistance. Used when schedule is critical or outdoor/UV exposure is a factor.
High-performance chemical resistance for environments with aggressive acids, solvents, or caustics. Standard specification for chemical processing and some food/beverage environments.
If you have a specific chemical exposure requirement, DTI can provide a chemical resistance chart for the proposed system before installation begins.
Surface Preparation
Epoxy bond strength is determined almost entirely by surface preparation. A properly prepared concrete surface has a profile equivalent to medium-grit sandpaper — open pores, no contamination, correct moisture content.
Moisture Testing Standards
- • ASTM F2170 — relative humidity in-slab testing
- • ASTM F1869 — calcium chloride surface emission test
