What Consistency Should the Paint be for Painting Glazes?
Glazing is about putting down thin layers of paint, so the paint should be fluid (thin) or you need to ensure that you spread it thinly when you paint. You can buy glazing mediums for both oil paint and acrylic. (If you add too much water to acrylic paint you run the risk of the paint losing its adhesive qualities; see this Acrylic Painting FAQ.) A common ‘recipe’ among oil painters is to mix 50:50 turpentine and oil. Some bought oil painting mediums (such as Liquin) will help speed up the drying time of oil paint.
