1．Assess the flatness of the joint

Upon completion of the jointing process, a preliminary evaluation should be conducted to ascertain the smoothness of the surface and the quality of the joint. A well-executed joint will present as a level line; any observed irregularities may indicate insufficient adhesive application or issues with the pressure exerted during the jointing process.

2．Examine for the presence of black edges

The occurrence of black edges along the joint is typically indicative of inadequate cleaning or suboptimal quality of the sewing rod. Moreover, excessive force applied during the pressing of the seam can result in scratching, which is particularly discernible on lighter-colored tiles.

3．Verify the curing of the adhesive

It is essential that the sealant is fully cured and hardened after the application. If the sealant remains pliable during the inspection phase, it signifies a quality issue that necessitates removal and reapplication to prevent subsequent detachment.

4．Inspect the corners of inside and outside

The ceramic tile corner of inside and outside is a critical area that poses a higher level of construction difficulty, demanding a superior skill set from the installer. Should the joint appear unnatural or rough, immediate adjustments and rework are required.

5．Check for signs of collapse or detachment

The occurrence of seam collapse or detachment is usually attributed to an excessively narrow gluing angle, inadequate seam cleaning, excessive moisture in the gap affecting adhesion, or the quality of the sealant itself.

6．Evaluate the aesthetic qualities of the seam gloss texture

The color and luster of the sealant should remain consistent pre- and post-construction. Should the sealant appear dull during the acceptance phase, the temporary addition of auxiliary catalysts may be considered to maintain performance, although this may mask underlying inferior quality.

✅ Ensure no detail is overlooked during the acceptance procedure

If all criteria are met, congratulations are in order for a successful completion.
