Alum Salt - sel d'alun
Alum salt (also known as potash alum) is made form hydrated double potassium aluminum sulfate. It is used as a wood finish and adheres well to plant based pigments like walnut stain, sandalwood and mahogany. It also can be used as a fixer for pigments and lime paint. This product helps to balance the absorption of a surface which creates a more even finish. Alum Salt also can serve as a light protective layer. The product can also be used to clean and disinfect wood surfaces before applying natural paints.

Apply to a dry and clean surface with a brush taking care to coat the whole surface evenly. Allow at least 24 hours to dry. A second coat is recommended to be applied once the first coat is dry.
