Which of the following is NOT a reason to use plastic cement?

Choosing not to use plastic cement for repairing brick walls is justified because plastic cement is specifically designed for materials like asphalt and roofing shingles where its properties can provide effective sealing and bonding.

Plastic cement is a type of material that excels in applications requiring flexibility and durability against weather exposure, making it suitable for sealing around pipes and adhering shingles where moisture resistance and adhesive strength are critical. In contrast, brick walls require more structural integrity and are often repaired with materials that can bond more effectively with masonry, such as mortar or specialized brick repair compounds.

Using plastic cement on brick walls may not provide the necessary support and bonding quality needed for a long-lasting repair, emphasizing why this option is not recommended for that particular application.
