The intense effort made in R&D has allowed us to develop continuous flooring with greater RESISTANCE.

Both the base, the intermediate layers and those of finishing and sealing are studied to achieve the best results in the most important performance variables:

  • Water resistance and Chemicals and therefore resistance to the stains
  • resistance to scratching and abrasion
  • resistance to compression
  • cracking
  • Adherence


Resiststone EX It has a high resistance to water even before varnishing. This is very important because it is the main difference with traditional microcements, which are very hydrophilic. So it will not be stained if there is any fault in the varnish (a scratch, a pore...) as the rest of the microcements do.

Resiststone EX it is the best option in terms of chemical and water resistance indoors (shower plates, washbasins, bathrooms).Resistone microcement washbasin cabinet

Compressive strength, or surface hardness, measures the coating's ability to resist high pressure/sqcm while avoiding impact from falls, stilettos, chairs, or other objects.

Resistone EX exhibits impressive surface hardness. Even though the lower layers must have some flexibility to avoid cracking. So you have to be careful with the legs of heavy furniture since, although they do not seem dangerous, they have a lot of weight on a small surface. It is a matter of weight/surface ratio.

EX Ground Laboratory Tests

Surface Hardness UNE-EN 13892-6: 184N/mm2

Flexion Resistance UNE-EN 13892-2:2003: 16,6 MPa

Impact Resistance UNE-EN ISO 6272:2012:

– 1500mm Fall: NO CRACKS

– Diameter of the mark produced at 1500mm: 8,8 mm


Scratch resistance refers to deep damage from a sharp object. It is measured visually.

Abrasion resistance refers to measures of the effect of repeated microdamage. It is measured by measuring the dust that is removed from the material when it is brushed with sandpaper. This mainly depends on the varnish.

The result of our varnish according to the Abrasion Tables is (CS 17/ 1000U/1000g) 19mg.


Modern microcements do not crack unless there are movements in the surface on which they are applied, concrete, tiles... Then the elasticity of the different layers comes into play to prevent movements from being translated into the coating as cracks.

There are different base layer systems. The highest performance is achieved with EPlastic.

EP-Elastic lab tests:

  • Tensile strength 15N/mm2
  • Elongation at break 110% at RT


Adhesion is a key requirement, mainly in exterior projects (Exteriors and Pools). Since they are susceptible to vapor pressure coming from under the coating when there is humidity and heat shock.

Pull-out test in wet cement shows failure in concrete.


It is more resistant than a wooden floor and has less contribution to fire than a laminate floor, but of course the tiles work much better with this parameter.

For this kind of product classification is Class B-S1, DO (EN 13501-1).

B– Building materials having a very moderate fire contribution.

S1– Very Limited amount of smoke developed.

DO– No flaming droplets or debris.

It easily withstands the heat of a hot frying pan and even covers a fireplace.
