Before applying the topcoat, it is crucial to verify that the stone-effect paint has completely dried, as this is a key factor in the success of the stone-effect paint application.

2. For stone paint application requirements, the viscosity can be adjusted with clean water. It should be tested incrementally from less to more, under the supervision of an experienced master.

3. Prior to each initial spraying, conduct a spraying test on a sample board. Adjust if necessary and confirm that the color tone and spray width are correct before proceeding to the formal spraying.

4. Due to uneven color distribution at the spray joint location, it is advisable to coat the next section as soon as the first one is finished.

5. During construction, windows and doors, as well as non-construction areas, are shielded and protected. Prevent upward construction sequences to avoid color contamination. Instruct scaffolding dismantling or other construction personnel to prevent damage to walls and to refrain from stepping on them.
