General notes
- All characteristics mentioned in this data sheet are based on a temperature of +23 °C without draught and a relative humidity rate of 50%.
- Higher temperatures and lower humidity rates accelerate, lower temperatures and higher humidity rates delay the setting process.
- Comply with the national standards and/or guidelines, for ex. leaflets of ZDB (Central Association of German Construction Industry); if not issued and if necessary, request technical advice.
- For installation of natural or artificial stone slabs, follow the supplier’s recommendations. If in doubt, carry out preliminary tests.
- Do not use a material that has already stiffened.
Special notes
- Ensure that the drainage mortar is sufficiently efficient. For improving the horizontal drainage performance, we recommend installing a drainage mat, for ex. Gutjahr Aquadrain EK, on the dry waterproofing layer (for ex. the 2-comp. reactive waterproofing slurry weber.tec Superflex D 2 or the 2-comp. waterproofing compound weber.xerm 844).
- When using weber.xerm 869 on a bitumen membrane, a drainage mat (for ex. Gutjahr Aquadrain EK) or separating underlay, the minimum dry layer thickness of weber.xerm 869 is 5 cm.
- Always apply weber.xerm 869 in earth-moist consistency in order to achieve optimal drainage.
