1. Is a private individual able to make his own Bealstone?
Regarding the application itself, a private individual could do his own BEALSTONE on small surfaces. However, in practice, for larger areas, it is not always feasible. BEALSTONE requires indeed special and very expensive tools (rotary sander with diamond disks) that quite often only professionals possess.
3. What is the difference between a slab, a screed or stabilized soil?
Slab: (wet mix) is armed and is used to stabilize the building. The look is raw and in general unpolished. Cement load: 350 kg/m³
Screed: (Wet mix) is lower in cement, 250 kg/m³, no aggregates but only sand and cement.
Stabilized soil: (dry mix) is even poorer in cement, is rather used, for instance, for paved floors, because it crumbles. Forbidden for MORTEX.
5. 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.
6. 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!
7. 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.
9. 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.
10. 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).
