Step-by-Step Repair Guide

Step 1: Prepare the Surface

Make sure the ceramic pieces are clean and dry. Use acetone to remove any dirt or grease.

Step 2: Choose the Right Adhesive

Step 3: Apply the Adhesive

Using a paintbrush, apply a thin layer of adhesive to the crack. Ensure that the adhesive seeps into the crack for better bonding.
