Tinley Park Epoxy Flooring installs ESD flooring in Tinley Park, IL, serving surrounding cities including Country Club Hills, Mokena, Matteson, Midlothian and Hazel Crest. With more than 20 years of floor coating experience, we approach static-control floors as engineered systems, because a floor that looks right but tests out of range does nothing to protect sensitive electronics.
An ESD floor is a coating built to carry static charge away from people and equipment in a controlled way, through a conductive primer, grounding points and a static-control topcoat. It protects circuit boards, components and devices from electrostatic discharge that can damage them without anyone noticing at the moment it happens.
The south suburbs have a strong base of electrical and light manufacturing, along with labs, clinics and data rooms where static is a concern. Each of those spaces has its own target range, and our written proposal names the system, the target resistance and how the floor will be tested at completion.
How ESD Flooring Works
Conductive and Static-Dissipative Ranges
ANSI/ESD STM7.1 classes static-control floors by their electrical resistance, tested at 10 volts. A conductive floor measures below 1.0 x 10^6 ohms, while a static-dissipative floor measures from 1.0 x 10^6 up to below 1.0 x 10^9 ohms.
Conductive floors drain charge quickly and are used where explosive materials or very sensitive devices demand it. Dissipative floors drain charge more slowly and suit most electronics assembly, repair and testing areas, which is why they are the most common choice.
The Floor as Part of a System
ANSI/ESD S20.20 asks that floors in electronics handling areas measure below 1.0 x 10^9 ohms, and it evaluates the person, footwear and floor together. The standard’s goal is that a person wearing approved, grounded footwear cannot generate more than 100 volts while walking.
That means the floor alone is not the whole answer. Conductive footwear or heel straps, grounded workstations and a cleaning program all play a part, and we coordinate the floor with whatever static-control program the facility already follows.
Grounding Points and Conductive Primers
A static-control floor carries charge through a conductive primer layer, often with a copper tape grid, to grounding points tied to the building’s ground. The topcoat is formulated with conductive materials so charge moves from the surface down into that grid.
We plan the grounding layout before installation and mark each connection point. A floor with too few grounds, or with a broken path at a seam, can test well in one area and poorly in another.
Where ESD Floors Are Used
Electronics Assembly and Repair
Circuit board assembly, component handling and electronic repair areas are the classic use for ESD flooring. Workers moving between benches and storage generate charge with every step, and the floor gives that charge a controlled path to ground.
Labs, Clean Rooms and Medical Spaces
Laboratories and some medical areas use static-control floors to protect instruments and sensitive equipment. These spaces also need floors that clean easily and resist chemicals, which a static-control epoxy can provide.
Server Rooms and Data Closets
Server rooms, network closets and control rooms benefit from static-control flooring where equipment is serviced regularly. A dissipative floor reduces the risk of discharge when technicians handle boards and drives.
Many of these rooms are small spaces inside larger buildings, such as a repair bench area in a warehouse or a network room in an office. We can install a static-control floor in just that zone and transition it cleanly to the surrounding floor, so the whole building does not have to be coated to protect one room.
Installing an ESD Epoxy Floor
Surface Preparation and Old Coatings
The slab is diamond ground or shot blasted to a measured profile, and old coatings, adhesives and sealers are removed completely. Dust is captured at the machine, which matters even more in facilities with sensitive equipment nearby.
Cracks and spalls are mapped and repaired before the conductive layers go down. A crack that opens later can break the conductive path, so repair quality affects electrical performance as well as appearance.
Moisture Testing
Moisture rising through a slab can affect both adhesion and resistance readings. We test with a calcium chloride kit under ASTM F1869 or relative humidity probes under ASTM F2170, and use a moisture-mitigation primer where the result calls for one, all recorded in the scope before the price is final.
Cure Conditions and Product Compliance
Static-control coatings need the right slab temperature and dew point spread to cure properly, and we schedule the coats around those readings. Products are chosen within the Illinois VOC limits for floor and industrial maintenance coatings set in 35 Ill. Adm. Code Part 223.
Cold or humid conditions during cure can leave amine blush on the surface, a film that also interferes with conductivity. Controlling the room’s temperature and humidity during installation protects both the bond and the electrical readings, so we plan HVAC settings with the facility before the first coat.
Licensing and Facility Requirements
Illinois has no state flooring license, so we confirm each village’s contractor license, bond and insurance rules before booking. Many facilities also have their own safety orientation, access rules and documentation needs, and we work those into the schedule from the start.
Testing, Records and Care
Resistance Testing at Completion
When the floor has cured, we test resistance at points across the floor with a calibrated meter and record the readings against the target range. Readings outside the range are investigated and corrected before the job is handed over.
Documentation for Quality Programs
Facilities with static-control or quality programs need a record of the floor as installed. We provide the readings, the product data and the grounding layout so the floor can be audited and retested later.
We also explain what the coating warranty covers and what it excludes before the contract is signed. Moisture from below, impact damage and contamination from incompatible cleaners are the usual exclusions, and knowing them helps a facility protect both the floor and its readings.
Cleaning and Maintenance
Waxes, floor finishes and some cleaners leave an insulating film that pushes resistance out of range over time. We provide cleaning instructions for the specific product installed, and we recommend periodic testing as part of the facility’s own static-control checks.
Scheduling Around Operations
Electronics and lab spaces often cannot shut down for long. We phase the work by area and use overnight and weekend windows where needed, and the schedule is agreed in writing before work begins.
