  • Release of corrosive substances: CT

  • Compressive strength: C25

  • Tensile bending strength: F4
Notice
  • Not suitable as a top surface without additional coverings or top surfaces!

  • Be sure to add water in the appropriate quantities! Adding more water results in reduced strength and increased shrinkage. Such low-strength layers have a reduced load capacity, we therefore recommend removing them!

  • Do not add water or fresh joint mortar to CERAfix 202 that has already started to harden to make it processable again. Loss of strength may result!

  • The properties of the substrate are essential when it comes to ensuring the successful application of the product; the substrate therefore must be carefully prepared, cleaned and primed!

  • If water is removed too quickly by e.g. room heating, strongly absorbent substrates, draughts, solar radiation etc. there is a risk of cracking!

  • Ventilation of the installation location is necessary, however, draughts during processing and during the hardening process must be avoided as well as direct sunlight. The internal and floor temperature must be at least 5 °C during processing and for one week thereafter! Dehumidifiers must not be used in the first 3 days!

  • Sulphite leaching adhesive or water-soluble floor covering adhesives must be completely removed!

  • Largely remove old, water-resistant floor covering adhesives with tools. 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 full reaction! Do not exceed a maximum single layer thicknesses of 20 mm!

  • Not suitable for use on poured tarmac screeds!

  • In the case of calcium sulphate screeds, the CM moisture content without underfloor heating must not exceed 0.5 % and with underfloor heating 0.3 % at the time of levelling with CERAfix 202. Thoroughly prime with CERAfix 103 or CERAfix 203 and sprinkle plenty of TEGAfix 430 quartz sand! After reaction has occurred (approx. 16 hours), sweep off and vacuum up the excess quartz sand. Then use CERAfix 202 to smooth up to a maximum layer thickness of 20 mm. Subsequent moisture ingress must be prevented.

  • Contact between the cement-based mortar and the magnesite screed causes destruction of the magnesite screed by chemical reaction "magnesia expansion". Backwards moisture load from the substrate must be excluded by appropriate means. Magnesite substrates must be mechanically roughened and primed with epoxy resin CERAfix 103 or CERAfix 203. Spread plenty of fresh 0.5-1.0 mm grit quartz sand across the fresh epoxy resin layer. After approx. 16 hours* waiting time, further laying work can take place. Do not exceed a maximum single layer thicknesses of 20 mm!

  • Edge, field, building and movement joints must be observed. These must be carried over or integrated at the specified location and suppressed with suitable means, e.g. edge strips! Dummy joints must be carved out once the CERAfix 202 has hardened up to a third of the applied layer thickness!

  • Only use clean tools and clean water!

  • To assess how mature the covering is, perform a moisture measurement using the CM unit.

  • The technical data sheets of the products used must be observed!

  • Protect surfaces that do not require treatment from exposure to CERAfix 202!

  • Current applicable regulations must be observed!
