21. Is Mortex compatible with underfloor heating?
Yes, with a traditional heating, i.e. with a screed above it. Regarding the application, the heating should be turned off four days before the application and put back into service (by steps of 2 to 3 °C every 48 hours above the support temperature) once the Mortex is completely dry (minimum 7 days).
23. Why can I not apply high thicknesses of Mortex?
Mortex has been studied and designed to be a micro-mortar applied in layers from 1 to 1.5 mm with a maximum thickness of 3 mm per system. The application process must be followed in order to ensure the technical nature of Mortex. An extra thickness with an unsuitable drying time can cause microcracks in Mortex. In deco, everything is allowed!
24. What is the lifetime of Mortex once applied?
Projects done with Mortex 20 years ago still give satisfaction today. However, this does not constitute a warranty. It all depends on the application quality, the use made of it and its maintenance.
25. Are expansion joints needed on Mortex surfaces?
Mortex does not require any expansion joints except if there are some on the support. If they were not provided in the support in places where they are needed, then you will have to consider making them in the Mortex coating.
26. With Mortex, is it possible to get a fully homogeneous surface?
We can never get a completely homogeneous rendering with MORTEX; there will always be a “mineral” effect. However, it is possible to manage some effects according to the applicator’s experience: everything is possible!
