Superb craft and painting mediums with a Polyvinyl Acetate (PVA) base. They dry almost transparent to a completely flexible finish, so they can be mixed with any colour or pigment without loss of brilliance when dry. Especially effective with a range of paints. Ideal for modelling, mixing, glazing or as a strong adhesive on porous material. As an economy measure, PVA mediums can be diluted to form a lightweight adhesive and they form a transparent glaze when dry so small objects can be secured. They also render difficult surfaces suitable for painting and strengthen card and paper in model making. They are a good adhesive for Quickprint and mixed with sand, make a realistic cement.
