Introduction
Staining after Tile Delamination
Type of Building: Commercial Building
Type of Façade: Small dimension mosaic tiles on backing wall
This case demonstrates one of the consequences of tile delamination. Dirt can be accumulated in the areas where tiles had delaminated. Once washed down by rain, staining occurs.
Dirt staining is very common with tiled façade, due to the presence of long lengths of tile joints. Dirt can be accumulated along these joints which can be carried down the façade by rain (rainwater runoff).
Moisture movements and/or retention will induce other problems including dirt, biological stain, corrosion, efflorescence and sealant deterioration:
