Application methods refer to the various techniques used to apply products or substances to surfaces or areas. Common methods include spraying, brushing, rolling, and dipping. Each method has its advantages and is chosen based on the type of product, the surface being treated, and the desired outcome. In agriculture, application methods are crucial for distributing fertilizers and pesticides effectively. Techniques such as drone spraying and broadcast spreading ensure even coverage over large areas. In construction, methods like roller application and spray application are used for paints and coatings, impacting the finish and durability of surfaces.
