- 01
Inspect and prepare the substrate
New and existing 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 30 minutes at 30 °C
- 03
Apply with the correct tools
Recommended methods: Roller, Brush, Airless spray. Confirm coat count and thickness for the project.
- 04
Protect through the required cure
Final cure 7 days

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 Body coat
Rayson FloorGuard R50 serves as the body coat. Confirm the complete build-up against the substrate, exposure and project requirements.

Choose something else when
- Minimum substrate temperature 5 °C; mix and cure between +10 °C and +35 °C
- Substrate moisture content must not exceed 5%
- Prepared substrate must reach at least 1.5 N/mm² pull-off strength
- Mixed material must be used within its pot life; cures faster in hot weather and in large batches
- Requires a Rayson epoxy primer — not a self-priming system
- Not for exterior UV-exposed surfaces — epoxy yellows and chalks outdoors
- Exterior UV-exposed surfaces — epoxy coatings yellow and chalk outdoors
- Use without a Rayson epoxy primer
- Substrates with standing water or moisture content above 5%
- Hot aggressive washdown or thermal-shock areas — specify a PurScreed PU-cement screed

What to know before specifying Rayson FloorGuard R50.
What finish does FloorGuard R50 give?
Applied plain it cures to a smooth gloss; broadcast with graded aggregate between coats it builds a slip-resistant texture for ramps and wet areas. Both are the same coating, finished differently.
How is FloorGuard R50 applied and at what coverage?
It is roller-, brush- or spray-applied over a Rayson epoxy primer, normally in 2 coats at 0.3–0.5 kg/m² per coat. Actual coverage varies with the substrate condition and porosity.
Does FloorGuard R50 need a primer?
Yes. It is applied over a Rayson epoxy primer such as PrimeBond E20 — one to two primer coats depending on substrate absorbency — which seals the surface and provides the adhesion the system relies on.
Can it be used in car parks and food production areas?
Yes — as a sealing coat over a broadcast system it suits multi-storey and underground car park decks, and wet process areas in the food and beverage industry. For hot, aggressive washdown, consider a PurScreed PU-cement screed instead.
Is it suitable for outdoor use?
No. Like all epoxies it yellows and chalks under UV, so it is an interior product. For UV-exposed decks, finish with a Rayson UraForce polyurethane topcoat.
