For the waterproofing of the metal inclined roofs in this project, ALCHIMICA’s exposed metal roof system based on the HYPERDESMO® SYSTEM was used. In this project, weathering steadily had damaged the large units of the metal roof sheets and especially the cut edges causing the removal of the protective coatings and revealing the bare metal core to further corrosion.

For this system, MICROSEALER-50, the low viscosity polyurethane based primer, was used for the priming of the substrate and then for the protection of the metallic roof joints and cut edges, HYPERSEAL®-EXPERT-150 used for sealing the inner angles and/or GEOTEXTILE-50 used for better future cracks protection. For the main membrane, HYPERDESMO 850 was chosen, due to its thixotropic properties, as it is ideal where rheology is very important. Finally, a top coat of HYPERDESMO®-ADY 500 was used for color stability and UV protection.
