Accelerate the hardening of your dough with our White Coutrai Siccative. This additive increases the oxygen uptake of your oil to give you total control over setting speeds. Pale i n colour and lead-free, it does not alter light colours and increases the uniformity of the paint. Use it sparingly at a rate of two to three drops per colour stroke to avoid drying out too quickly and cracking the paint. Like turpentine and mineral spirits in combination with oil, this additive can be used to make your own medium. Show more
