ArexA PU-T

Transparent sealing of balcony and terrace floors

The transparent sealing is essential for open and exposed areas.

Balconies and terraces, patios and pavements belong without doubt to the most intensively used parts of a building. They are permanently exposed to the elements and constant temperature variations. Especially when these areas are covered with ceramic tiles, cracks in mortar joints occur oftenly through which water can ingress and cause harm. PAN-TECH offers you a transparent sealing system with unique transparent coating technology: the transparent, liquid polyurethane-sealing system ArexA-PU-T. There are two models: shiny and matt-finished.
