Watec® 3E

The reinforced thin-layer drainage


The reinforced thin layer drainage with triple effect
for ceramic tiles and plaques laid floating.

Watec®3E reliably and permanently drains, ventilates and uncouples outdoor ceramic coverings, providing secure protection from frost damage and efflorescence caused by accumulated water in cavities in the thin-bed mortar. This avoids cracks in and delamination of the covering.
