Influence of the Thin Coating Repair on the Prevention Properties for Fall-off of Tile Facing at external Walls

Part 2. Adhesion strength

Abstract

After tiled to the ground repaired with thin coating mortar, the tile tensile strength adhesion examination was evaluated in following conditions; The condition after (1)the standard care health, (2)the thermal stress repetition care of health reproducing thermal movement, and (3)a distortion flattery nature examination. As a result, it was observed that the adhesion strength with mortar tended to become a little weaker after (2) than (1), and that the adhesion strength with elastic adhesive tended to become stronger after (2) than (1). Also, at the part, where the float sound was not checked, the adhesion strength with elastic adhesive after (3) retain more than 70% in respect of lamp irradiation and more than 80% in respect of lamp non-irradiation. It was showed that elastic adhesive had the outstanding exfoliation tightness.
