Whitewash Whitewash Whitewash, or calcimine, kalsomine, calsomine, or lime paint is a type of paint made from slaked lime (calcium hydroxide, Ca(OH)) and chalk calcium carbonate, (CaCO), sometimes known as "whiting". Various other additives are sometimes used. Whitewash cures through a reaction with carbon dioxide in the atmosphere to form calcium carbonate in the form of calcite, a reaction known as carbonation. It is usually applied to exteriors; however, it has been traditionally used in interiors of food preparation areas, particularly rural dairies, because of its mildly antibacterial properties. Whitewash can be tinted for decorative use and is sometimes painted inside
Automotive paint 85% of lacquer paint can evaporate into the air, polluting the atmosphere. Enamel paint is better for the environment and replaced lacquer paint in the late 20th century. Water-based acrylic polyurethane enamels are now almost universally used as the basecoat with a clearcoat. High-pressure water spray jets are directed to the body. Without proper pretreatment, premature failure of the finish system can almost be guaranteed. A phosphate coat is necessary to protect the body against corrosion effects and prepares the surface for the E-Coat. The body is dipped into the Electro-Coat Paint Operation (ELPO/E-Coat), then a high voltage is applied.
