The intense effort in research and product development has allowed us to achieve greater resistance in continuous pavements.
The base, the intermediate, finish layers and sealing are studied to achieve the best results in the important performance variables that a microtopping should be good at:
- Water and chemical resistance and therefore stain resistance
- Scratch and abrassion resistance
- Compression resistance
- Cracking bridging capabilities
Resistone EX has a high water resistance even before varnishing it. This is very important because it is a difference with traditional microcements, wich are very hidrophilic, it does not rely on the varnish to avoid water penetration. So it will not be stained if there is any little fail in the varnish (a scratch, a pore… will not) as other microcements does.
Resistone EX is the best option for special water & chemical resistance indoors (showerplates, basins, baths).
The compression resistance or surface hardness, measures the coating capacity to resist high pressure/sqcm avoiding the impact of spike heels, chairs or objects falls.
Resistone EX shows an impressive surface hardness. Although the layers beneath have to have some flexibility to avoid crackings, so care has to be taken with legs of heavy furniture have enough surface and are not agressive shapes. It is a matter of weight/surface.
EX Ground Laboratory Testing
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 CRACKINGS
– Diameter of the mark produced at 1500mm: 8,8mm
Scratch resistance refers to deep damage produced with a sharp object. It is measured visually.
Abrassion resistance refers to measures the effect of micro damage produced repetidely. It is measured weighting the dust that is taken away from the material when brushed with a sandpaper. This mainly depends of varnish.
The result of our varnish is Taber Abraser ( CS 17/ 1000U/1000g ) 19mg.
Modern microcements does not crack unless there are movements in the substrate over which they are applied, weather concrete, tiles… Then comes in to play the elasticity of the different layers to avoid that that movements translate to the coating as a fissure.
We have diferent base coats systems. The highest performance is achieved with EPlastic
EP- Elastic Laboratory Testing:
- Tensile Strength 15N/mm2
- Elongation at break 110% at RT
Adhesión is a key requirement mainly in exterior projects (Floors and Pools) which are susceptible of suffering vapour pressures From beneath the coating, when there is moisture and sun hits.
Resistone EPHumid Primer
Pull-off test on wet concrete shows failure in concrete.
FIRE & HEAT RESISTANCE
It is more resistant than a Wood Parket, it has less contribution to fire than a laminated floor, but of course tiles perform much better about this parameter.
For this kind of products 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.
There is no problem when puting a hot pan over it or if installed on a fireplace.
