12. Should Mortex be protected?
Mortex behaves as a natural stone (waterproof but micro-poreous on its surface). Therefore, a protection against stains (wine, grease…) is recommended indoor: varnish, oil, etc. In all cases, we recommend tests and samples beforehand to validate the appropriate protection.
13. We are thinking about installing a dynamic floor heating, which means that the floor covering is directly placed on the circuit, without intermediate screed. Is it possible with Mortex?
For this type of floor heating, no project has been made in Mortex yet. If this type of heating accepts thin screeds, the application of Mortex might be considered. Trials need to be done!
14. Who to ask to apply Mortex?
On request, Beal can provide you with a list of recommended professionals who apply MORTEX. We always advise you to visit projects of the professional you are going to choose and to request a sample of the selected product with its protection, since it can significantly change the look and colors. This will also allow you to assess the finishings, rendering, inside corners, outside corners, etc.
16. On which surfaces can I apply Mortex?
Mineral-based surfaces such as screed, cementing, concrete, etched tiles, lightweight panels (type LuxElement, Wedi, Jackoboard…), plasterboards (not recommended in showers)… and wooden supports: medium (MDF), (not bakelized) plywood WBP,… Tests on glass and metal have also been successfully completed. The support must be healthy, stable, non-greasy and non-powdery. The junctions between the various panels and/or materials must be consolidated.
17. 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).
19. 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!
20. 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.
