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
Smooth concrete (minimum 28 days old, moisture content below 5%)
- 02
Prepare the material as specified
One pre-weighed component; stir well for 2 minutes with a mixing paddle before use
- 03
Apply with the correct tools
Recommended methods: Short-bristled brush, Roller. Confirm coat count and thickness for the project.
- 04
Protect through the required cure
Surface dry approximately 1 hour at 28 °C
Coating system cutaway
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 Primer
Rayson PrimeBond W10 serves as the primer. Confirm the complete build-up against the substrate, exposure and project requirements.

What to know before specifying Rayson PrimeBond W10.
Is PrimeBond W10 suitable for occupied buildings?
Yes — it is water-based, low VOC and low odour, which is exactly the situation it is designed for. Normal housekeeping around wet coatings still applies.
Does it need mixing with a hardener?
No. It is a single-component product supplied ready to use; just stir thoroughly for about two minutes before application.
How do I build an anti-slip finish from this primer?
Broadcast a fine aggregate into the wet primer, sweep off the excess once dry, then seal with UraForce WB52 topcoat. The aggregate grade sets the texture — our technical team can advise on the right grade for your cleaning regime.
How porous can the substrate be?
Coverage varies from roughly 5 to 10 m² per litre with porosity; very absorbent screeds may need a second priming coat to achieve a full seal.
Can it go straight over a power-floated slab?
The slab still needs mechanical preparation to remove laitance and open the surface — priming is not a substitute for preparation.
