Do not mix more CERAfix 201 than can be used within the processing time. Not suitable as a top surface without additional coverings or top surfaces. Refer to the primer table before use. From a layer thickness of 20 mm, CERAfix 103 epoxy primer must be applied; then dust with TEGAfix 430 quartz sand.
Higher temperatures and low relative humidity accelerate the film formation time; lower temperatures and higher relative humidity extend the film formation time.
Not suitable as a top surface without additional coverings or top surfaces!
Be sure to add water in the appropriate quantities!
If too much water is added, this will result in signs of separation, which are associated with low-strength layers and increased shrinkage. These low-strength layers must be removed with tools!
- The substrate quality is essential for effective floor filling. Absorbent substrates negatively affect the flow characteristics of the filler, so the substrate must be carefully prepared, cleaned and primed!
- To reliably prevent pore formation, carefully brush CERAfix 101 into the substrate and allow to dry completely. Use a spiked roller to deaerate the CERAfix 201 layer while it is still liquid!
- If water is removed too quickly, e.g. by room heating, strongly absorbent substrates, draughts, solar radiation etc., there is a risk of cracking!
- The installation location must be ventilated, however, draughts and direct sunlight must be avoided during processing and during the hardening process. The indoor and floor temperature must be at least 5°C during application and for one week thereafter! Dehumidifiers must not be used in the first three days!
- Sulphite leaching adhesive or water-soluble floor covering adhesives must be completely removed!
- Mechanically remove as much as possible of the old, water-resistant floor covering adhesives. Small amounts of dispersion-based water-resistant floor covering adhesives (area percentage < 20 %/m², evenly distributed) can remain on the substrate. Clean the substrate and then prime it with CERAfix 103 or CERAfix 203, sprinkle with plenty of TEGAfix 430 quartz sand and vacuum after curing! Do not exceed the maximum layer thicknesses of 10 mm!
- Not suitable for use on poured tarmac screeds!
- To assess whether it is ready for covering, a moisture measurement must be carried out using the CM device (see table with limit values in the TDS).
- Contact between the cement-based mortar and the magnesite screed leads to the destruction of the magnesite screed by "magnesia expansion" chemical reaction. Backwards moisture load from the substrate must be prevented using appropriate means. Magnesite substrates must be mechanically roughened and primed pore-tight with CERAfix 103 or CERAfix 203 epoxy resin. Spread plenty of fresh TEGAfix 430 quartz sand over the fresh epoxy resin layer.
- After approx. 12 hours*, further laying work can be performed. Do not exceed the maximum layer thicknesses of 10 mm!
- When using a mixing pump, for example PFT G4 or G5 or equivalent, the mixing pump and hoses must be flushed out in the event that work is interrupted!
- If using a PFT G4 mixing pump, the water flow meter must be set to approx. 370-420 l/h using the standard PFT G4 mixing shaft, the D6-3 rotor and the Twister D6-3 stator. The flow rate with this configuration is approximately 20 l/min. For larger layer thicknesses/areas, it is recommended to use the pump unit, D8-1.5 rotor and D8-1.5 stator. The water flow meter must then be set to approx. 800-850 l/hour. The flow rate is then approximately 35 l/min. The PFT consistency test socket can be used to check and set the correct water supply based on the flow spread. This must not exceed 61 cm on prepared substrate and should be checked continuously during processing! If the spreading dimensions are exceeded, too much water has been added. Consequently, signs of separation may appear that can lead to insufficient strength development and increased shrinkage with sunken layers.
- Preliminary work, such as filling transitions and levelling out ruptured areas and unevenness, is performed using CERAfix 202 permanent repair mortar!
- Edge, field, building and movement joints must be observed. These must be retained or incorporated at the prescribed location and sealed off by suitable means, e.g. CERAfix 208 edge strips! Dummy joints must be carved out once the CERAfix 201 has hardened up to a third of the applied layer thicknesses!
- Only use clean tools and clean water!
- The technical data sheets of the products used must be observed!
- Protect surfaces that do not require treatment against exposure to CERAfix 201!
Currently applicable regulations must be observed! For example:
- DIN 18157
- DIN 18534
- DIN 18560
- DIN EN 13813
- DIN 1055
- TKB information sheets from Industrieverband Klebstoffe e. V. (Industry Association of Adhesives)
