11. 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).

12. 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.

13. 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!

14. 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!

15. 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.

16. Is Mortex slippery?

Everything depends on how the applicator tightened the grain. A well tightened and very smooth Mortex, if it is wet, will be more slippery than a “rough” Mortex (you can use a sponge float to bring out the grain).

17. How to clean limescale on my Mortex?

To remove lime stains from your Mortex, you can use white alcohol vinegar diluted with lukewarm water that you spray on the surface and leave on for a few minutes before scrubbing with a soft sponge. Consult our complete maintenance sheet on

18. I have some Mortex and Bealcryl over, can I keep them for another project?

If products are kept in good storage conditions, you can reuse them for another project. This is why Beal sells neutral, untinted products.

19. How much does Mortex cost?

Usually, from 6 m², a professional asks between €110 and €145 per m² including VAT (i.e. €90 to €120 per m² excluding VAT) (application and products). It depends on the surface area to cover, the support type, the final destination of the application (pool, floor, shower, furniture,…) and the desired finished look. For products only, count between €30 and €50 per m² including VAT (i.e. €25 to €42 per m² excluding VAT). For surface areas smaller than 6 m², consult an applicator.

20. What type of seal should I use between Mortex and other materials?

A MS Polymer flexible seal because it leaves no grease marks on Mortex, unlike silicone.
