This sequence supports early planning. It does not replace the current Technical Data Sheet, approved method statement or project-specific technical review.
- 01
Inspect and prepare the substrate
Mechanically prepared concrete (minimum 28 days old, moisture content below 5%)
- 02
Prepare the material as specified
Two pre-weighed parts, mix ratio 4:1 (A:B) by weight; mix mechanically for at least 2–3 minutes; pot life up to 25 minutes at 28 °C
- 03
Apply with the correct tools
Recommended methods: Steel trowel, Notched rake, Squeegee and roller, Spike roller immediately after trowelling. Confirm coat count and thickness for the project.
- 04
Protect through the required cure
Full cure approximately 7 days; minimise heavy traffic for 72 hours after application

Every layer has a job—from prepared substrate to service surface.
This diagram explains a typical system position, not a fixed specification. Primer, body coat, finish, thickness and detailing must be confirmed for the project.
Position in the system Finish
Rayson StaticGuard CX90 serves as the finish. Confirm the complete build-up against the substrate, exposure and project requirements.

Choose something else when
- Applying above the stated film thickness reduces conductivity — thickness control is critical
- Measured resistance readings are affected by ESD clothing, ambient conditions, measurement equipment, floor cleaning and test personnel
- Minimum substrate temperature 5 °C; curing between +10 °C and +35 °C; concrete moisture content maximum 5%
- Requires planned earthing points and post-installation resistance verification
- Areas with no earthing provision — conductivity is useless without a ground path
- Exterior UV-exposed surfaces
- Thick-build applications beyond the stated film thickness — conductivity drops
- Substrates with moisture above 5%

What to know before specifying Rayson StaticGuard CX90.
Is StaticGuard CX90 conductive or dissipative?
Its average electrostatic behaviour is in the 10⁴–10⁶ ohm range, which sits in conductive ESD territory. The reading achieved on site also depends on installation, earthing, cleaning and how the measurement is taken — always verify against your facility standard.
Why must the film thickness not be exceeded?
Conductivity depends on the conductive network through the coating. Applying thicker than specified increases resistance and can push the floor out of its target range.
How is the floor earthed?
Grounding points are installed as part of the system, connected to the building earth by the electrical contractor. Agree the earthing layout with the facility engineer before installation.
How do we prove the floor meets its ESD target?
With documented resistance testing after full cure, using the measurement method your facility standard specifies. Rayson recommends retesting on a scheduled basis thereafter.
What cleaning products can be used?
Use cleaners that do not leave insulating films — waxes and polymer polishes can raise surface resistance and defeat the static control.
When can production equipment move back in?
Keep heavy traffic off for at least 72 hours and allow around 7 days for full cure before resistance verification. Confirm programme timings with our technical team.
