Material Base / Vehicle

Water-thinnable, 2-component solid epoxy resin.

Packaging/Package Size

  • Standard:
    5 kg, 10 kg plastic combi packaging,
    40 kg plastic container (Base: 24 kg plastic hobbock, Hardener: 16 kg plastic bucket)
  • ColorExpress:
    10 kg plastic combi packaging

Colours

  • Standard:
    5 kg packaging: Pebble Grey (Kieselgrau)
    10 kg packaging: Pebble Grey (Kieselgrau), Concrete Grey (Betongrau), Off-White (Altweiss)
    and White (Weiss)
    40 kg packaging: Pebble Grey (Kieselgrau), Concrete Grey (Betongrau)
    Special tints are available on request.
  • ColorExpress :
    Can be tinted to more than 21,000 colour shades via the ColorExpress station on site. 
    The FloorColor plus colour collection allows exclusive colour design.
    Depending on the tint, Base 1, Base 2 or Base 3 can be mixed via the ColorExpress station.

    Discolouration and chalking effects may occur with weathering and UV light exposure. 
    The pigmentation in, e.g. coffee, red wine or leaves (organic dyestuffs) and various chemicals, e.g. disinfectants, acids, etc., may cause discolouration. Scratch-marks may appear on the surface due to continued rubbing/mechanical stress. The functional capability of the coating will not be affected by these changes.
    Slightly pigment abrasion may occur on the surface in case of intensive or dark shades; a special surface treatment/care or the application of a transparent sealer may be necessary.

Suitable Substrates

All types of mineral substrates (e.g. concrete, cement, anhydrite and magnesite screeds, renders/plasters) and hard asphalt screeds in the interiors. On wall surfaces also suitable for use on Capaver Glass Fabrics, Capadecor AkkordVlies-Z (glass fleece) and filler Caparol-Akkordspachtel KF.
The substrates must be sound, dimensionally stable and free from brittle particles, dust, oils, fats/greases, rubber abrasion/skid marks and all materials that may prevent good adhesion.
Check cementitious, synthetic resin improved flow mortars for compatibility by a trial coating, if necessary.
The adhesive tensile strength of substrates must be 1.5 N/mm2 on an average, with a minimum single value of 1.0 N/mm2.
Substrates must have achieved their equilibrium humidity.
Concrete and cement-based composition-floor (screed): max. 5 % by weight
Anhydrite screed: max. 1 % by weight
Magnesite screed: 2 – 4 % by weight
Xylolithe (Magnesium Oxychloride) screed: 4 – 8 % by weight

Hard asphalt screeds have to correspond at least to hardness class IC 15 and should not warp on the given temperature and mechanical load conditions.

Substrate Preparation

Prepare the substrate by suitable means, e.g. grit blasting (shot peening) or milling, fulfilling the above mentioned requirements. The additives of hard asphalt screeds should be visible after preparation for at least 75%. Always remove existing 1-component paint coatings and loose 2-component coatings.

Vitreous surfaces and surfaces of rigid existing 2-component coatings must be cleaned and roughened (flattened) by sanding or blasting or should be primed with Disbon 481 EP-Uniprimer.
Repair spallings and defects with Disbocret® PCC or Disboxid EP mortars and fillers, filling them flush with the surface.
Level surface roughness on mineral substrates with a scratch-filler application of Disbopox 453 Verlaufschicht (self-levelling flow coat) according to Technical Information, if necessary.

Preparation of Material

Stir up the base material, then add the hardener and stir intensively with a low-speed electric agitator (max. 400 rpm). Continue stirring until a homogeneous, streak-free colour shade is achieved. Pour the mixture in another clean container and stir again very thoroughly. Do not thin the material for intermediate and finishing coats.

Mixing Ratio

Base material : hardener = 3 : 2 parts by weight

Method of Application

The material may be applied with a paint brush, roller (textured polyamide roller, e.g. Rotanyl roller 8 mm, pile height 11 mm, manufacturer: Rotaplast) or suitable spraying equipment.
(Airless, min. 50 bar, nozzle size 0.015 – 0,017 inch, spray angle of 45°, treat with a roller when applied.)

Surface Coating System

Priming Coat
Prime new, unused mineral substrates and hard asphalt flooring/screed with Disbopox 447 E.MI Wasserepoxid, diluted with approx. 5–10% of tap (potable) water. 
Prime used and highly absorbent substrates with Disbopox 443 EP-Imprägnierung. Apply the priming coat very intensively with a sealant brush.

Coating
Apply intermediate and finishing coats of undiluted material. A third work step may be necessary on high-contrast substrates and very intensive colours (e.g. when using ColorExpress Base 3).

Surface Design
Strew/scatter Disboxid 948 Color-Chips on the freshly applied coating. Allow to dry, then apply Disbopur 458 PU-AquaSiegel for smooth top coat or add/mix 3 % by weight of Disbon 947 SlideStop for non-skid surfaces.

Workability

At 20 °C and 60% relative humidity, approx. 90 minutes. Higher temperatures shorten and lower temperatures extend the pot life.

Please Note: The end of pot life (workability) is not easily noticeable. Application after the approx.
90 minutes at 20 °C may cause gloss level variations and colour changes and will lead to diminished stability/strength and poor adhesion. Avoid excessively thick applied layers in one process (more consumption). Provide for proper ventilation during drying and hardening.

Application Conditions

Material, Ambient Air and Substrate Temperature:
Min. 10 °C and max. 30 °C during application and drying.
Relative humidity must not exceed 80%. Substrate temperature should always be min. 3 °C above the dew point temperature.

Waiting Time

The waiting time between work steps (coats) should be at least 16 and max. 48 hours at 20 °C. After longer breaks, the surface of the preceding coating must be roughened/sanded.

Higher temperatures shorten and lower temperatures extend the waiting time.

Drying/Drying Time

At 20 °C and 60% relative humidity, walkable after approx. 1 day. Ready for stress/mechanical loads after approx. 3 days and completely hardened after approx. 7 days.
The drying time is correspondingly longer at low temperatures. During the hardening process (approx. 24 hours at 20 °C) the coating should be protected from moisture, otherwise surface faults and diminished adhesion may occur.

Tool Cleaning

Immediately after use or during longer breaks with water or warm soapy water.
