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
Luminous paint Luminous paint Luminous paint or luminescent paint is paint that exhibits luminescence. In other words, it gives off visible light through fluorescence, phosphorescence, or radioluminescence. There are three types of luminous paints.. Fluorescent paints offer a wide range of pigments and chroma which also 'glow' when exposed to the long-wave "ultraviolet" frequencies (UV). These UV frequencies are found in sunlight and some artificial lights, but they—and their glowing-paint applications—are popularly known as black light and 'black-light effects', respectively. In fluorescence the visible light component—sometimes known as "white light"—tends to be reflected and perceived normally, as colour; while the UV component
