Liquid coatings are protective layers applied to surfaces in a liquid form, which then dry or cure to form a solid finish. These coatings can be made from various materials, including paints, varnishes, and sealants, and are used to enhance appearance, protect against corrosion, and provide durability. Commonly used in industries such as automotive, construction, and manufacturing, liquid coatings can be applied using methods like spraying, brushing, or rolling. They come in a wide range of colors and finishes, allowing for customization while serving functional purposes like waterproofing and UV protection.
