How to Get Appropriate Spread Rates in ESD Floors

February 4, 2019

Dur-A-Gard ESD, an electrostatic dissipative resinous floor system, provides a static dissipative surface of 106-109 Ω/Square that protects against electrostatic discharge when properly installed.

Since an ESD resinous floor is basically an electrical system that consists of a conductive primer layer, grounding strips, and resistive body/top coats, the thickness of the applied coatings is critical as it directly impacts the resistivity of the cured floor.

The best practice to achieve the necessary spread rates is to always mark out the application area by mix size planned, use the recommended v-notched squeegee, and verify the spread rate using a mil gauge. The resistivity of the completed ESD floor should be evaluated after the floor has cured at least 24 hours.
