Final answer:
To properly repair a damaged tire, apply a liberal coat of chemical cement in a circular pattern. This ensures even distribution and adhesion for the repair material.
Step-by-step explanation:
To apply a liberal coat of chemical cement to the cleaned surface of the damaged tire, you should use a circular pattern. This method ensures that the cement is spread evenly across the entire surface, providing a strong and uniform adhesion for the patch or repair material that will be applied over it. It is important to follow the specific product instructions for both application and drying times to ensure a successful tire repair.
