At one of the most authoritative European testing laboratories, have been tested the thermohygrometric behavior, the impact resistance and the bonding strength of the spideREX K8 System ennobled by finishes from different manufacturers.
The test wall, transferred to the hygrothermal chamber, has been subjected to 80 heat/rain cycles and then to 5 freeze/thaw cycles, representative of the state of the wall after 25 years. Different types of finishes has been tested with this method.
At the end of the test, the wall showed no sign of swelling, peeling and/or degradation. Test passed.
The impact resistance must be defined according to the deformations generated by a rigid and non-deformable body, thrown against the wall with an energy of 3J and 10J.
The portion of the wall where the colored coatings have been applied, has been evaluated to be a “class I” while the area without finishing, a “class II”.
The binding force has been measured on the wall portion with various types of colored coatings. The different finishes showed the same behavior, that is they did not come off the support (RXM plaster) and did not show any defect.
