Sikafloor ESD is Sika’s electrostatic control epoxy coating family, anchored by two topcoats that split the ANSI/ESD S20.20 resistance classes between them. Sikafloor-270 ESD is the conductive option, a novolac epoxy reading 2.5×10⁴ to 1.0×10⁶ Ω per ANSI/ESD S7.1 and ASTM F-150. Sikafloor-200 ESD is the static dissipative option, 1.0×10⁶ to 1.0×10⁹ Ω. Both apply at 15 to 18 mils, hold their electrical values through the full coating thickness, and read consistently regardless of relative humidity. Craftsman Concrete Floors installs the complete Sikafloor ESD line nationwide as an authorized Sika installer, with resistance verification per S7.1 recorded and delivered on every project.
The demand for this page arrives fragmented. Specs and purchase orders write the products as Sikafloor 270 ESD, Sika 270 ESD, or a legacy number from before Sika absorbed MBCC’s flooring business on May 2, 2023, and some still say Sika anti static epoxy when they mean the dissipative class (anti-static proper describes a higher 10¹⁰ to 10¹² Ω band that no product in this family occupies). Whatever name the document carries, the current US family is the one on this page, and every value here traces to the Sika product and system data sheets linked below.

The Sikafloor ESD Family
Buyers arrive at the Sika ESD coating line holding a product number from a spec, and the number decides the resistance class before anything else does. The family splits cleanly between Sikafloor-270 ESD on the conductive band and Sikafloor-200 ESD on the static dissipative band, each anchoring its own published system build-up. Which class a facility’s S20.20 program actually needs is a separate question. Our conductive vs dissipative page answers it.
Sikafloor-270 ESD, the Conductive Topcoat
Sikafloor-270 ESD is a two-component chemical-resistant novolac epoxy that reads 2.5×10⁴ to 1.0×10⁶ Ω per ANSI/ESD S7.1 and ASTM F-150, with body voltage generation under 30V in ESD-compliant footwear. It qualifies to ANSI/ESD S20.20-2014 tested per STM97.1 and carries its conductivity through the entire coating thickness rather than through a humidity-dependent surface layer. Sika’s data sheet lists it for electronics manufacturing, military and aerospace work, and hazardous dust or explosion environments, where the conductive band is the program requirement. Application runs 15 to 18 mils.
Sikafloor-200 ESD, the Static Dissipative Topcoat
The static dissipative half of the family is Sikafloor-200 ESD, a four-component epoxy holding 1.0×10⁶ to 1.0×10⁹ Ω per ANSI S7.1 and ASTM F150, with body voltage under 15V per ANSI/ESD STM97.2. Its August 2023 data sheet qualifies it against ANSI/ESD S20.20-2021. The operational difference from 270 is the primer: 200 ESD imparts static dissipative readings as a stand-alone topcoat over a standard Sika epoxy primer such as Sikafloor-161, 160, 165 FS, or 1620, so a dissipative install carries one less electrical layer to verify. Sika lists it for the same electronics, data processing, and cleanroom environments as 270, minus the novolac chemical-resistance angle.
Seam-Welded ESD Vinyl Sheet
Sheet-format ESD vinyl flooring seam-welds into larger panels, cutting the joint count well below tile. Fewer seams means fewer ground-path breaks, though the welded joints still exist and still need conductive upkeep over the floor’s life. Resilient-flooring contractors install ESD vinyl, not Craftsman. It serves the same modular use cases as VCT with better plane continuity, and it remains a seamed system next to a poured floor’s unbroken conductive surface.
Documented System Build-Ups
Each topcoat anchors a published Sika system. The dissipative Sikafloor ESD system runs 24 to 30 mils: Sikafloor-161 primer at 8 to 10 mils under a 200 ESD topcoat at 16 to 20 mils. The conductive, chemical-resistant Sikafloor ESD CR E system runs 26 to 33 mils and adds the electrical layer 270 depends on. That stack is Sikafloor-161, then Sikafloor-222W conductive primer at 4 to 6 mils, then the 270 topcoat. Substrate preparation is identical for both, shot blast to ICRI CSP 3-6 over concrete testing at least 3,625 psi at 28 days, with moisture verified per ASTM F2170 before any resin goes down.

Where Sikafloor ESD Installs Go Wrong
An ESD floor that fails resistance testing usually failed before the topcoat was mixed. On the Sikafloor line the failure points are documented in the product data sheets themselves — the wrong conductive primer, an unverified ground plane, over-applied topcoat, and testing scheduled before electrical properties develop. Each has a TDS-stated control. This is the checklist Craftsman crews run, and the reason a spec’d Sikafloor system still needs an installer who has read the data sheet.
The 222W Primer Requirement
The Sikafloor-270 ESD data sheet names one acceptable conductive primer, Sikafloor-222W, and states outright not to use Sikafloor-220W with it. The two products sit one digit apart on a purchase order. They do different electrical jobs. Before the 270 topcoat is applied, the primed surface must test below 5.0×10³ Ω per ANSI/ESD S7.1 and ASTM F-150; that reading is the acceptance test for the ground plane itself. Skip it, and a resistance failure stays invisible until the finished floor is tested after cure, when the fix means grinding off a new topcoat.
Grounding Points and Thickness Control
Both data sheets call for a minimum of one grounding point per 1,000 square feet, typically adhesive copper tape placed on the isolation primer beneath the conductive layer and tied to building steel or a verified electrical ground. Ground continuity is what turns a resistive coating into a charge path. Thickness cuts the other way. The topcoats apply at 15 to 18 mils, and both data sheets state the product loses its ESD properties if applied beyond the recommended thickness, which makes a heavy-handed squeegee pass a genuine electrical defect rather than wasted material.
Cure Windows and Final Verification
Foot traffic at 12 to 16 hours and full cure at 5 to 7 days are the mechanical milestones; full electrical properties on Sikafloor-270 ESD arrive within 10 days of application at 73°F. Final resistance verification per ANSI/ESD S7.1 is scheduled against that electrical timeline, not the walk-on date, and the readings go into the closeout package with the primed-surface values recorded earlier. Craftsman installs the line as an authorized Sika installer with in-house W-2 crews. Our installation-process page walks the sequence from substrate testing to documentation.

Frequently Asked Questions
Sikafloor ESD is Sika’s electrostatic control epoxy coating family, anchored by the conductive Sikafloor-270 ESD at 2.5×10⁴ to 1.0×10⁶ Ω and the static dissipative Sikafloor-200 ESD at 1.0×10⁶ to 1.0×10⁹ Ω, both measured per ANSI/ESD S7.1 and ASTM F-150. Each topcoat anchors a published system build-up, and both hold their electrical values through the full coating thickness without depending on humidity. Craftsman Concrete Floors installs the line nationwide as an authorized Sika installer.
The resistance class. Sikafloor-270 ESD is conductive at 2.5×10⁴ to 1.0×10⁶ Ω, a novolac epoxy specified where hazardous atmospheres or defense requirements call for the conductive band, and it qualifies to ANSI/ESD S20.20-2014 tested per STM97.1. Sikafloor-200 ESD is static dissipative at 1.0×10⁶ to 1.0×10⁹ Ω per its S20.20-2021 data sheet and covers most electronics and cleanroom programs. Which band a facility’s program requires is the question our conductive vs dissipative page answers.
Sikafloor-222W ESD conductive primer, applied at 4 to 6 mils, and the data sheet states not to use Sikafloor-220W in its place. The primed surface must test below 5.0×10³ Ω per ANSI/ESD S7.1 and ASTM F-150 before the topcoat is applied, which makes that reading the acceptance test for the ground plane. Sikafloor-200 ESD differs; it reaches its dissipative range as a stand-alone topcoat over a standard primer such as Sikafloor-161.
24 to 30 mils for the dissipative Sikafloor ESD system and 26 to 33 mils for the conductive Sikafloor ESD CR E system, with the topcoats themselves applied at 15 to 18 mils. Thickness has an upper bound as well as a lower one; both product data sheets state the coating loses its ESD properties if applied beyond the recommended range. Craftsman crews check wet-film thickness during the pour for that reason.
Under 30V on Sikafloor-270 ESD and under 15V on Sikafloor-200 ESD with ESD-compliant footwear, measured per ANSI/ESD STM97.2. Those are the data-sheet values; the ANSI/ESD S20.20 program threshold they sit inside is 100V. Footwear matters as much as the coating, since STM97.2 measures the person, footwear, and floor together as one walking system.
Within 10 days of application at 73°F for Sikafloor-270 ESD, per its data sheet. Foot traffic is possible at 12 to 16 hours and full mechanical cure takes 5 to 7 days on both topcoats, so final resistance verification per ANSI/ESD S7.1 is scheduled against the electrical timeline rather than the walk-on date. A floor tested too early can read out of band on Monday and in band a week later.
Sika’s data sheets list electronics manufacturing, data processing facilities, military and aerospace work, hazardous dust or explosion environments, and pharmaceutical cleanrooms. Craftsman Concrete Floors installs the Sikafloor ESD line anywhere in the United States; in-house W-2 crews mobilize nationwide, and we have installed industrial flooring since 1999.
