What is the purpose of using a wax and grease remover during surface preparation?

The purpose of using a wax and grease remover during surface preparation is primarily to float dirt and contaminants for easier removal. Before applying any paint or finish, it's crucial to ensure that the surface is clean and free from impurities, such as grease, wax, oil, and dirt. These contaminants can interfere with adhesion, leading to problems like peeling, bubbling, or uneven finishes.

By using a wax and grease remover, the contaminants are effectively lifted off the surface, allowing for a cleaner substrate. This not only prepares the surface for painting but also enhances the overall quality and durability of the finish. Proper surface preparation is critical in any painting process to achieve optimal results.
