Siccative can be added to linseed oil paint to accelerate the oxidation (drying). In general, you should avoid adding extra siccative as it accelerates the aging of the paint and can make the paint film brittle. The content of siccative in our linseed oil paint is adapted for painting outdoors. So do not add any extra desiccant outdoors. When painting indoors, we recommend that you add max 10 ml. per liter of paint. SÄKERHETSDATABLAD
