Spray coatings are protective layers applied to surfaces using a spray method. This technique allows for even coverage and can be used on various materials, including metal, wood, and plastic. Spray coatings can enhance durability, provide weather resistance, and improve the appearance of objects. These coatings come in different types, such as paint, varnish, and sealants, each serving specific purposes. They are commonly used in industries like automotive, construction, and manufacturing. The application process typically involves using a spray gun or aerosol can, making it a quick and efficient way to coat large areas.
