Abstract
This study was made to prevent tile facing on external walls from delaination. A adhesive strength test and a deformational performance test were conducted while varying the type of the base and the mode of base conditioning. As a result of the adhesive strength test, it was found that the concrete base provided higher bond strength than the mortar base regardless of the mode of conditioning and thus ensured satisfactory bond condition. The defor- mational performance test found that the tile facing applied to chipped concrete surface recovered well from deformation but the facing on unconditioned surface performed poorly. It was thus concluded that evaluating the capacity of preventing the spalling of tile facing by deformational performance test was more desirable than based on the result of a adhesive strength test.
