Suitable surfaces:
- Concrete
- Calcium sulphate screeds (CA, CAF)
- Poured tarmac screeds (AS)
- Magnesia screeds (MA)
- Cement screed (CT)
Specified consumption quantities are calculated values without additions for surface roughness and absorption, level compensation and remaining material in the container. We recommend always adding an imputed safety surcharge of 10 % onto the calculated consumption quantities. Higher temperatures shorten the application time. Lower temperatures increase the application and curing time. Material consumption also increases at low temperatures. The adhesion of individual layers to each other can be severely impaired due to the effects of moisture and contamination between the individual steps. Coating works require a surface temperature of min. 3 °C above the dew point temperature. If there is a longer waiting period between the individual steps or if already treated surfaces are to be recoated with liquid synthetic resins after a longer period of time, the old surface must be cleaned well and thoroughly sanded. Afterwards, a full, non-porous new coating must be applied. Ensure good ventilation during the drying and rehardening phase.
Avoid excessive layer thicknesses (additional material consumption) in the individual steps. This leads to cracks developing and possibly spalling and extend the waiting time between individual steps.
Clean all equipment with suitable solvents immediately after use.
Slight differences in colour are unavoidable due to different production methods and variations in raw materials. The same production method must be used for delimited area sections (same batch number of the delivery bundle).
Surface protection systems must be protected from moisture (e.g. rain, dew) for approx. 4-6 hours after application. Moisture causes whitening and/or tackiness of the surface and may cause the curing process to fail. Discoloured and/or tacky surfaces must be removed by e.g. sanding or abrasive blasting and reworked. Abrasive wear and tear can scratch the surface. Especially visible on dark shades. The functionality is not affected by this. Regular maintenance of the surface with suitable cleaning and care products is recommended to conserve the surface quality and finish for a long time.
The technical data sheets for the named products must be observed before work starts.

The usage instructions are recommendations based on the tests we have conducted and our experience; carry out your own tests before each application. Due to the large number of applications as well as the storage and usage conditions, we do not assume any liability for a specific application result.

We ensure the consistent quality of our products. We reserve the right to make technical changes and further develop products. Please observe the technical data sheet!
Cured product residues can be disposed of in accordance with waste code AVV 15 01 06.
Used for sealing cement-bound floor surfaces, magnesia screeds, calcium sulphate screeds and well sealed poured tarmac screeds, e.g. in warehouses, garages, workshops, cellars and internal rooms etc.
The surfaces to be treated must be dry with ≤ 5 % residual moisture (CM method), firm, load-bearing and non-slip. Free from loose and adhesion-reducing substances, e.g. dust, grease, rubber abrasion etc.
The B component is added to the A component. It must be ensured that all of the hardener flows out of its container. The material is thoroughly mixed with an appropriate stirrer to a homogeneous consistency. The mixing time is three minutes. Do not process the mixed material straight from the container it was supplied in. Put the compound into a clean mixing bucket and carefully stir again.
Primer:
- Thin CERAfix 108 with 8 % to max. 10 % water
- Apply the material in one step (cross coat) with a coating and sealing roller (approx. 6 mm pile height)
Compensating compound/scratch coat:
- Mix CERAfix 108 with quartz sand (grit 0.1-0.35 mm) in a mixture ratio 1.0: 0.5 parts by weight
- The quartz sand is mixed into the previously homogeneously mixed resin and hardener components that have been put into a new container. It must be ensured that the liquid and solid components are mixed evenly.
- The finished mixture is applied to the primed surface in one step in a layer thickness of max. 2 mm using the scratch coat method. Ventilate the applied compensating compound/scratch coat several times with a suitable spiked roller
- After hardening, rework any unevenness with 100 grit sandpaper without scoring and suction off
- Consumption: approx. 1.6 kg/m² per mm layer thickness
Topcoat:
- CERAfix 108 is applied on the primer or scratch coat crosswise in one to two steps with a coating and sealing roller (approx. 6 mm pile height) in a rolling process
- Consumption: approx. 300-350 g/m² per step
