Material Base / Vehicle
Aqueous 2-component polyurethane dispersion.Packaging/Package Size
4 kg plastic combi-packaging (also ColorExpress)Colours
Pebble Grey, Stone Grey, Light Grey.
Special tints available on request.
Exclusive colour designing is possible by the use of FloorColor collection. May be tinted via ColorExpress machine system in numerous colours. Mix base 1, 2 or 3 according to the shade. 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/sliding. The functional capability of the coating will not be affected by these changes.

Suitable Substrates
Sound, adherent, rigid to viscous-rigid polyurethane and epoxy coatings.The substrates must be dry, sound, dimensionally stable, solid, free from all materials that may prevent good adhesion, e.g. loose/brittle materials, dust, oils, fats/greases or abraded rubber (skid marks).
Substrate Preparation
Prepare the substrate by suitable means, e.g. thorough sweeping and removing dust with a vacuum cleaner, in order to fulfil the above mentioned requirements.
Grind existing coatings thoroughly unto stress whitening. Seal new two-component coatings on the following day. For longer waiting periods the coating must be slightly roughened with fine-grained scouring pad. At lower temperatures the waiting time may be accordingly longer. Water-thinnable reaction resin systems require adequate time for drying.
Preparation of Material
Add the hardener to the base material and stir intensively with a low-speed electrical paddle (agitator; max. 400 rpm) until a homogenous shade without streaks is achieved. Pour the mixture into another container and continue stirring.Mixing Ratio
Base material: Hardener = 85 : 15 parts by weight.Method of Application
Apply by brush or with a textured polyamide roller, e.g. Rotanyl roller 8 mm, pile height 11 mm, manufacturer: Rotaplast.
Always work wet on wet to achieve an uniform aspect.
Surface Design
Scatter/strew Disboxid 948 Color-Chips speedily into the freshly applied coating. Allow to dry and seal smooth with Disbopur 458 PU-AquaSiegel or seal for anti-skid treatment by adding 2 top 3% by weight of Disbon 947 Slidestop.
Surface Coating System
Smooth surface
Apply a uniform cross-coat of material in a thin layer. Seal connected surfaces in one application without interruption to avoid visible lapping. Different-coloured substrates may require a second coat to achieve sufficient opacity. A third work step may be required for highly intensive colours (e.g. tinted with ColorExpress base 3) or different highcontrast colours.
Anti-skid treatment/slip-resistant surface
Add 2% by weight of Disbon 947 Slidestop to the material, mix thoroughly and seal as described above (Smooth surface). For longer breaks the material should be stirred in between.
Consumption
| Smooth surface | |
| Disbopur 459 PU-AquaColor | approx. 100-150 g/m ✱ per coat |
| Anti-skid treatment/Slip-resistant surface | |
| Disbopur 459 PU-AquaColor Disbon 947 SlideStop Fine | approx. 100 g/m2 approx. 2-3 g/m2 |
✱ Two coats are necessary for roughtextured substrates, to achieve a porousfree surface. Exact values are determined by trial application on site.
Workability
At 20 °C and 60% relative humidity approx. 45 minutes.Higher temperatures shorten and lower temperatures extend the pot life.
| The end of pot life is not noticeable. Application after the recommended 45 minutes leads to variations in gloss level and shade, lower strength and diminished adhesion to the substrate. Apply uniformly to avoid different gloss levels and traces, visible in the sidelight (especially for deeper shades). Do not apply in an excessively high layer thickness (increased consumption > 200 g/m2) to avoid the forming of bubbles in the film. Provide for sufficient ventilation (air supply/ deaeration) during drying and hardening. |
Application Conditions
Material, atmospheric, and substrate temperature
must be min. 10 °C and max. 25 °C during application and hardening.
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 the individual work steps should be at least 16 hrs. and max. 24 hours at 20 °C.Drying/Drying Time
At 20 °C and 60% relative humidity, walkable after approx. 16 hours. Ready for mechanical loads after approx. 3 days and completely hardened after approx. 7 days.Tool Cleaning
Immediately after use and during longer breaks with water or warm soapy water.German Certificates

CE Labelling
EN 13813
CE labelling is based on EN 13813 "Screed mortars, screed compounds and screeds – screed mortars and screed compounds – Properties and Requirements" defining the requirements for screed mortars being used for floor constructions in the interiors. The standard also include synthetic resin coatings and sealing.
Products matching the above mentioned standards are to be labelled with the CE mark. Additional engineer standards are effective for the use in Germany in structural safety relevant areas. Conformity is documented by the Ü sign (Überwachung = supervision) on the container. Established by documented evidence of conformity 2+ with controls and tests on the part of the manufacturer and notified bodys.
