Recipe: Lime-Casein Wash

Lime-casein is most suitable for wall painting. In contrast to borax-casein or ammonium carbonate-casein, lime-casein is largely weatherproof. Small additions of casein to lime colors enhance their weatherability and abrasion resistance. There is only one disadvantage: Lime-casein needs to be used up the same day! When working with lime-casein, you must use pigments that are fast to lime/lime-stable. Casein is suitable for the following surfaces: paper, woodchip, glass fiber fabric, gypsum cardboard, gypsum plaster, lime plaster, lime-cement plaster.

Processing

Dilute 1 liter of 4% lime-casein-solution with approximately 4 liters of water (the mixing ratio should always be 1:4). Add the water bit by bit and in small portions and stir constantly.
