31. Where can I find the products of the Mortex range?

You will find a list of all our dealers on the following link: Our points of sale.

32. MX05 – Is it possible to use other products than those in the MORTEX® coating range?

We can never guarantee products foreign to our brand for the simple and good reason that we do not control their manufacturing process.

Incompatibilities may arise directly during mixing, during application and long after application.

33. 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.

34. MX06 – Construction of a swimming pool with a MORTEX®-coating?

Yes, but only via experienced installor who strictly adhere to the POOL application systems.

Please contact our technical department.

35. 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.

36. MX07 – How to avoid stains on a varnished MORTEX® coating?

For a varnish to be efficient, it must be applied according to the rules of art and the prescriptions of the technical data sheets available on .
Damage on a scratched varnished substrate can be equivalent to that of an unprotected substrate.

Stains in these areas may be difficult or even impossible to remove.
The technical data sheet of each product (available on must scrupulously observed be during application.

In order to obtain efficient results, it is necessary to :
– to apply the protection on a clean and dust-free surface and wait until it completly dries.,
– apply the varnishes with suitable brushes and rollers and regularly cross each pass, lightening the pressure put on the tool crescendo.
– on a structured and/or open-pored support, tapping with an “ad hoc” brush is imperative to make the varnish penetrate to the bottom of the cavities formed by the pores. If this work is not carried out in this way, water and grease will penetrate into these cavities, will be picked up by capillary action and will reveal a stain that is difficult or even impossible to remove even under the chosen protection.

37. 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!

38. 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.

39. MX08 – How do I remove stains from a MORTEX® varnish coating?

If there are stains on a MORTEX® varnish coating, they are most probably due to the penetration of dirt through openings in the varnish (scratches, impacts) or to a deficient application of varnish that does not comply with the application protocol of the technical data sheet.

To repair and attempt to clean these stains, there is, a priori, no other solution than to sand the surface with a diamond tool to remove the varnish.

In fact, before the sanding operation, one could try to clean the stains by means of capillary action thanks to the application of several layers of absorbent paper (see in this FAQ the capillary cleaning technique).

If this work proves to be inefficient, it will be necessary to sand the part of the MORTEX® coating until the stain completely disappears, in order to apply a new MORTEX® coating, smoothing perfectly the surface of the coating, so as not to repeat the same problem.  The MORTEX COLOR F2 coating can, in some cases, make smoothing easier.

After the MORTEX® coating has dried (see technical data sheet available on, apply the varnish according to the technical installation instructions.

Attention: if you are in a waterproofing technique for a shower, you will have to reapply the missing parts to the system of the two coats of MORTEX COLOR 2N coating.
