Lime paint

Lime paint is a mineral paint, commonly used as exterior or interior wall paint. Made of slaked lime (calcium hydroxide) Sticks best on porous backgrounds such as plaster, cement or clay. Lime paint is rougher than chalk paint and is not uniform in color. Also called lime wash or white wash. White wash can give an aged look to wooden furniture. It doesn’t naturally stick very well to wood, unless the wood is roughened and porous. A binder such as cooked linseed oil or casein can help adhesion as well. ‘Lime paint is also highly alkaline and therefore naturally resistant to fungus and mold growth, making it ideal for bathrooms, kitchens, and children’s rooms’ (source: unearthed paints).
