Casein is a protein extracted from milk that acts as a natural binder for glues, paints, coatings and whitewash. Casein creates better adherence and increases elasticity. Casein is easy to use and is well adapted for painting on wood surfaces. It can also be mixed with pigments to make gouaches. DILUTION: 10g casein + 100g water + 2g alkali (lime, ammonia, sodium carbonate) Refrigerate for a few days to allow the mixture to swell. The alkali allows the casein to dilute in water. | Keep mixture refrigerated.
