Material Base / Vehicle

Liquid two-component epoxy resin with fine additives. Total solid as per "Deutsche Bauchemie".

Packaging/Package Size

15 kg tin combi-packaging, 25 kg container (base: 16.7 kg hobbock, hardener: 8.3 kg tin bucket)

Colours

Stone-grey (Steingrau), Pebble-grey (Kieselgrau). Individual colours on request.

Exclusive colour-designing possible with FloorColor colour collection. Discolouration and chalking effects may occur with weathering and UV light exposure. The organic dyestuffs/colourants in, e.g. coffee, red wine or leaves and various chemicals, e.g. disinfectants, acids, etc., may cause discolouration.

Colour deviations may occur with the use of individual/special colours. The filler may influence the colour effect, particularly if bright-toned product or material in intensive colours are used. Scratch marks may appear on the surface due to continued rubbing/sliding. Proper functioning of the coating will not be affected by these changes.

Suitable Substrates

Concrete and cement-based composition floor (cement screed).

The substrate must be sound, dimensionally stable, solid, dry, clean, and free from loose/brittle particles, dust, oils, fats/greases, rubber abrasion (skid marks) or other substances that may prevent good adhesion.
 
The pull-off (adhesive/tensile bond) strength of substrates must be 1.5 N/mm2 on an average, with a minimum individual value of 1.0 N/mm2.

Substrates must have achieved their equilibrium humidity: 
Concrete and cement-based composition floor (screed): max. 4 % by weight (CM method)
Test method for the mentioned values as per DAfStb, Maintenance Guideline part 3.

Rising damp/moisture must be avoided. If a risk of moisture from the ground is expected, then a pore-free priming coat of Disboxid E.MI Primer or Disboxid 462 EP-Siegel Neu (New) has to be applied.
In such a case the pull-off (adhesive/tensile bond) strength of substrates must be 2.0 N/mm2 on an average, with a minimum individual value of 1.5 N/mm2.
For all other substrates or proceedings a special technical advice by Disbon is required.

Substrate Preparation

Prepare the existing cement-based substrate very thoroughly by shot-blasting with solid shot/grit (shot peening), avoiding dust due to simultaneous suction-cleaning. 
The degree of removing layers of lower adherence is depending on pressure, type and amount of shot-blasting medium.
Grinding is only permissible for small (border) areas, except for the preparation using diamond grinding technique to remove layers of lower adherence.
In Germany: Follow BEB-Arbeitsblatt KH-0/U and BEB-Arbeitsblatt KH3, as well as Table 2.5 of the Guideline "Richtline Schutz und Instandsetzung von Betonbauteilen, Teil 2 des "Deutschen Ausschuß für Stahlbeton" / Protection & Repair of concrete elements, part 2 of "German Committeee for reinforced concrete".
Thoroughly clean existing, rigid/stiff 2-component coatings and roughen/flatten them by grinding or blasting to remove all remaining substances, care products and the like from the surface to be coated.
Repair spallings and defects with Disbocret® PCC or Disboxid EP mortars, filling them flush with the surface.
All material with silicone content cannot be used in the surrounding area (ambiance) before and during work, in order to avoid defects in the surface.

Preparation of Material

Add the hardener to the base material and stir intensively with a suitable low-speed electric paddle mixer (agitator; max. 400 rpm), until a homogeneous, streak-free colour shade is achieved. Pour the mixture into another clean container and continue stirring. Stir mixed material occasionally, during longer breaks.

Mixing Ratio

Base material : hardener = 2 : 1 parts by weight.

Method of Application

Apply the material with a smoothing trowel (steel float) and solvent-resistant texturing roller.

Surface Coating System

Priming Coat
Prime mineral substrates with Disboxid 420 E.MI Primer, filling all pores. Apply the primer with a smooth hard-rubber wiper (squeegee) working in back-pull technique, then treat the surface crosswise by roller.
Consumption:
Disboxid 420 E.MI Primer approx. 300 - 400 g/m2

Scratch-Filler (if necessary)
Level rough, porous substrates after priming with an additional coat of scratch-filler.
Consumption:
Disboxid 420 E.MI Primer approx. 660 g/m2 per mm of coating thickness
Disboxid 942 Mischquarz approx. 1 kg/m2 per mm of coating thickness.

Alternatively the following products can be used for priming and scratch-filler application, as per requirement:
Disboxid 460 EP-Ground
Disboxid 461 EP-Filler
Disboxid 462 EP-Siegel Neu (New)
For further details see the corresponding Technical Information.
Please note: If Disboxid 420 E.MI Primer is used for priming/scratch-filler application, then the surface must be recoated within 24 hours. Intermediate grinding is obligatory for longer waiting times. For all other priming materials follow the waiting times given in the corresponding Technical Information. 
Primed or filled surfaces can be tinted to match the following coatings in shade, in order to enhance the opacity of bright-coloured product and poorly hiding individual colours. A system coating as per AgBB test criteria is not possible, if Disboxid 460 EP-Ground and Disboxid 461 EP-Filler are used.

Application as Conductive Coating:

Laying the earthing connections
Allow the priming/scratch-filler coating to harden, then stick self-adhesive copper strips Disbon 973 (length: approx. 50 cm) circulating the wall area (see figure) in a distance of max. 20 m. A minimum of two earth connections is required. For this purpose use the Disboxid 975 Leitset (conductive set) with necessary contact points.
Surfaces that are separated by joints must be separately grounded. A maximum distance of ≤ 20 m between copper strips has to be respected in case of large, seamless surfaces.
Clean the surface of applied copper strips with a cloth, wetted with thinner Disboxid 419 Verdünner. The copper strips must always be connected by an expert for electrical supply with the earthing/grounding of the building after having finished the application of coatings.Layout for earthing connections:

2. Braided wire made of copper, 4 mm2 for connection to the earthing/grounding (ring line)

Conductive intermediate coating:
Roller-apply a conductive coating of Disboxid 471 AS-Grund or Disboxid 5022 WHG-Leitschicht on the priming coat. Allow the intermediate (conductive) coat to harden, then, before applying the finishing coat, check for sufficient conductivity. Resistance to earth must not exceed 5 x 104 ohm. Distance between measuring electrode and ground connection should be between 8 to 10 meters. Additional earthing connections must be installed, if the resistance is higher.
Consumption:
Disboxid 471 AS-Grund approx. 100 g/m2
Disboxid 5022 WHG-Leitschicht approx. 120 g/m2

Note: Ensure sufficient ventilation during drying and curing phases. On principle only one following coat is applicable. For repairs or reworks a conductive intermediate coat of Disboxid 471 AS-Grund or Disboxid 5022 WHG-Leitschicht (including earthing) is always required.


Coating (R10)
Apply a thin coat of Disboxid 467 E.MI Hartkornschicht with stainless steel smoothing trowel on the primer/scratch-filler coating or use Disboxid 471 AS-Grund or Disboxid 5022 WHG-Leitschicht for conductive coating system, then draw sharply over the surface. 
After that, treat the surface cross-wise with a coarse Moltopren roller (pore diameter approx. 2 mm). Therefore the freshly coated surface is walkable with special hobnailed boots. During application the roller should be rolled from time to time on a neutral substrate to become dry and should be replaced for the work on large surfaces after approx. 100 m2 of usage.
Consumption:
Disboxid 467 E.MI Hartkornschicht approx. 600 g/m2

Coating (R11)
Blow approx. 80 g/m2 of SiC (Silicon Carbide) 0.5 - 1.0 mm to the coating before the surface is rolled cross-wise (to obtain anti-slip class R11) and apply as described above.
Consumption:
Disboxid 467 E.MI Hartkornschicht approx. 600 g/m2
SiC (Silicon Carbide) 0.5-1.0 mm approx. 80 g/m2

Workability

At 20 °C and 60 % relative humidity (RH), approx. 40 minutes.
Higher temperatures shorten and lower temperatures extend the pot life.

Note: Due to the short pot life the material must be applied speedily, to avoid visible lapping.

Application Conditions

Temperature of Material, Ambient Air and Substrate:
Temperature must remain at a min. of 10 °C, max. 30 °C. 
Relative humidity must not exceed 80 %. The substrate temperature should always be min. 3 °C above the dew point temperature.

Waiting Time

Waiting time between Disboxid 420 E.MI Primer and the subsequently applied coating: min. 12 hours, max. 24 hours. Waiting time between Disboxid 471 AS-Grund and top coating: min. 16 hours, max.
2 days. Higher temperatures shorten and lower temperatures extend these time periods.

Drying/Drying Time

At 20 °C and 60% relative humidity, walkable after approx. 1 day. Completely hardened after approx.
7 days. Lower temperatures extend the drying time. During the hardening process (approx. 24 hours at 20 °C), the applied coating has to be protected against moisture to avoid surface faults and loss of adhesion.
