Paint adhesion is a basic but crucial concept in painting and coating work. It refers to how well paint sticks to a surface. Think of it like glue - good adhesion means the paint creates a strong bond and won't peel or flake off easily. Professional painters need to understand adhesion because it affects the quality and durability of their work. This involves knowing how to prepare surfaces properly, choose the right paint for different materials, and test if the paint will stick well. Poor adhesion can lead to paint failure and costly repairs, while good adhesion ensures a long-lasting paint job.
