Operation steps
1. Adjust the position of the L-shaped needle, leaving a seam allowance of ≥1.5mm. Using it in conjunction with a cross-stitch will yield better results
2. Insert the L-shaped needle along the gap, rotate it 90 degrees to secure the needle to the bottom of the brick, and then press down the handle to level it
3. Within 3-5 hours of application, before the tile adhesive has fully cured, rotate the tile 90 degrees in the reverse direction to remove it
4. Achieving a leveled surface results in a smooth and aesthetically pleasing tile surface
