Which of the following methods can be used to strip paint from metal surfaces?

Stripping paint from metal surfaces can be effectively accomplished by utilizing multiple methods, and each option presented serves as a viable technique within this context.

Sanding involves the use of abrasive materials to physically scrub away the paint layers. This method is particularly useful for smaller areas where precision is required and can ensure that the surface is smooth and ready for refinishing after paint removal.

Blasting, specifically sandblasting or media blasting, employs pressurized air to propel abrasive materials against the surface. This is a highly effective technique for removing paint quickly over larger areas and can also help in preparing the surface for new paint by creating a rough texture, which enhances paint adhesion.

Chemical stripping utilizes solvents or specialized products to dissolve the paint, allowing it to be wiped away without the need for abrasive techniques. This method is beneficial for intricate designs or components where mechanical methods might cause damage or be impractical.

Thus, the comprehensive nature of the answer indicates that each method plays a unique role in paint removal, making them all applicable techniques for stripping paint from metal surfaces. This versatility provides professionals with options tailored to different tasks and materials, ensuring effective paint removal in various situations.
