It is extremely challenging to duplicate the composition and appearance of historic paints using modern materials. Now contemporary painters can recreate that classical look, including the attractive, subtle unevenness of colour, the irregularity of surface texture, the depth provided by a glaze topcoat, and the directional lines of application, with historic recreated Milk Paint from The Original Milk Paint Co. Milk Paint is a traditional, long-lasting paint made from milk casein, clay, earth pigments and lime. It is a natural, non-toxic product that bonds with hard porous surfaces by way of a naturally forming resin, called calcium caseinate. It is predominantly used on sanded wood and cob walls, without the need for a primer or sealer.
