Pronunciation: [lˈa͡ɪmwɒʃ] (IPA) 
Limewash is a type of paint made of slaked lime and water, typically used to cover brick or other masonry. The word is spelled with a silent "e" at the end, which is not pronounced. In IPA phonetic transcription, the word is spelled /ˈlaɪmwɒʃ/, with the stress on the first syllable.

Limewash is a type of paint or coating made from a mixture of lime, water, and other natural ingredients. It is commonly used to cover and protect the surface of masonry, plaster, or other porous materials such as brick, stone, or adobe. Limewash has been used for centuries and is known for its durability and unique appearance.
The process of creating limewash involves slaking quicklime (calcium oxide) with water, thus creating a compound known as slaked lime (calcium hydroxide). This slaked lime is then mixed with water to form a milky liquid that can be applied to surfaces with a brush, roller, or sprayer. As the limewash dries, the water evaporates, and the lime gradually reacts with carbon dioxide from the air, which causes a chemical reaction known as carbonation. This reaction turns the limewash into a solid, protective layer with a distinct, matte appearance.
Limewash offers several advantages over other types of paint or coatings. It allows the treated surface to breathe, permitting the passage of moisture and preventing trapped moisture from causing damage. It also provides natural insulation and acts as a natural fungicide, inhibiting the growth of mold or mildew. Additionally, limewash is environmentally friendly as it is made from natural materials and does not contain harmful chemicals.
Due to its timeless and classical aesthetic appeal, limewash is often used in historical restoration projects or to create an aged appearance on new construction. It can be used both indoors and outdoors to enhance the beauty and longevity of a wide range of architectural surfaces.
The word "limewash" originated from the combination of two words: "lime" and "wash".
- "Lime" comes from the Old English word "līm" and the Middle English word "lim". It can be traced back to the Proto-Germanic word "*leimaz", meaning "sticky substance" or "birdlime". The term evolved through different Germanic languages, with related words like German "Leim" and Dutch "lijm", which all refer to adhesive substances.
- "Wash" has its roots in Old English as well, derived from the word "wæscan" or "wacsan". It evolved from the Proto-Germanic word "*watskan", which means "to wash" or "to wet". The word has similar equivalents in other Germanic languages, such as German "waschen" and Dutch "wassen".
