Impermeable to water


Protects the surface from moisture



Equalises vapour-pressure


Due to the fleece on the back, the air ducts remain on the bottom; these ducts have a vapour-equalising effect and thus discharge the enclosed moisture



Easy to apply


The specified layer thickness of the film ensures that a sufficient sealing layer is achieved



Bridges cracks


Improved bridging of cracks compared to, for example, when using slurry-type seal coatings



Highly elastic


Increased flexibility compared to, for example, when using slurry-type seal coatings



  • Traffic loads up to 3.5 kN/m² spot loads up to 2.0 kN/m²

  • Resistant to micro-organisms

  • UV stable
Notice

CERAfix 315 is a special design. We therefore recommend a contractual and written agreement.


  • Before applying CERAfix 315, spread a contact layer with CERAfix 300/301 on existing supporting tile surfaces and allow to harden!

  • CERAfix 315 is not suitable for high dynamic loads such as with industrial traffic!

  • CERAfix 300/301/SMP Sprint can be used to seal suitable edge and gutter elements. The substrate must then be prepared in a suitable manner, e.g.: Direct contact with metals such as copper, zinc and aluminium must be prevented by using a pore-tight primer with CERAfix 103/203 and TEGAfix quartz sand. A pore-tight primer is produced in two stages with CERAfix 203 or CERAfix 103. The first stage involves liberal application to the substrate cleaned with acetone (check compatibility) and careful coating. Once this layer has begun to react such that it can no longer be spread through (about 3-6 hours*), another epoxy resin layer is applied and scattered with TEGAfix 430 quartz sand. Consumption approx. 800 g/m². A connection to the surface seal is then formed over the cured blinding layer, e.g. using CERAfix 316 sealing tape with CERAfix 300/301/SMP Sprint.

  • To decouple wood substrates, we recommend decoupling panels CERAfix 206.

  • Edge, field, building and movement joints must be carried over or integrated at the specified locations and suppressed by suitable means, e.g. edge insulating strips! Dummy joints must be friction-locked or secured against height offset and formed as a movement joint in the surface covering.

  • CERAfix 315 must not be adhered or worked over with solvent-containing products!

  • On cool, damp surfaces and in rooms with high humidity and/or low temperatures, an extended drying time of the structure is to be expected. In such cases, the product will take longer to reach a load-bearing state, including resistance to water.

  • Protect the CERAfix 315 construction from the effects of water and freezing in the installed state until complete drying; this will take longer in unfavourable weather conditions compared to normal conditions*.

  • The relevant applicable technical information sheets of the indicated products must be observed!


Current applicable regulations must be observed! For example:

  • DIN 18352

  • DIN 1055
