DISBON DisboFLOOR 460 2K-EP Primer 25kg

DISBON DisboFLOOR 460 2K-EP-Primer 25 kg – transparent, for concrete and cement screed

DisboFLOOR 460 is a transparent, solvent-free 2K epoxy resin (total solid) for priming and scratch-filling mineral floor surfaces prior to floor coatings. It cures well even at 10 °C, is permanently resistant to moisture, and is suitable for the Disbon parking garage system OS 8. One 25 kg container is sufficient as a primer for approx. 60–125 m².

With DisboADD 946 quartz sand mixture, DisboFLOOR 460 also becomes a binder for coves and for reprofiling damaged areas. (Former name: DisboXID 460)

Advantages

• Good curing even at 10 °C
• Permanently moisture-resistant
• Tested against moisture from behind for over 250 days
• Low-viscosity (approx. 700 mPas) – penetrates well into the substrate
• Complies with DIN EN 1504-2 and DIN V 18026 (Surface protection systems for concrete)
• Curing adjustable with DisboADD 903 accelerator

Areas of application

• Primer for epoxy and PU floor coatings
• Scratch filling for leveling rough surfaces
• Disbon parking garage system OS 8
• Coves and reprofiling of damaged areas

Note: Not suitable as a top sealer.

Determine exact consumption values by applying a test area on-site.

Application

1. Checking the substrate

Concrete or cement screed: level, load-bearing, firm, and free of dust, oil, and grease. Average bond strength at least 1.5 N/mm², residual moisture max. 4 CM-%.

2. Preparing the substrate

Prepare mechanically, e.g., by shot blasting or diamond grinding. Open pores and voids to create a finely roughened surface.

3. Mixing

Add component B to component A and mix thoroughly with a slow-speed stirrer (max. 400 rpm). Transfer to a clean container and mix again thoroughly.

4. Priming

Pour the material onto the surface, distribute pore-filling with a rubber squeegee, and roll over with a medium-pile roller in a cross-coat pattern. Apply two coats to highly absorbent substrates.

5. Recoating

Recoat the primer within 24 hours or lightly broadcast with sand while fresh (grain next to grain) – e.g., using our Quartz sand fire-dried. Do not broadcast for coatings under 1 mm.

Application conditions: Material, air, and substrate temperature 10–30 °C, rel. humidity max. 80%, substrate at least 3 °C above the dew point.

Suitable coating: DISBON DisboFLOOR 475 SL. Alternatively, pre-filled: DISBON DisboFLOOR 461.
