Glazing

Glazing is a technique where a thin layer or layers of translucent medium is applied over a base layer of paint. Because the top layers are not opaque, the layers beneath are still visible, creating a rich quality of color. This same technique can also be used to alter the texture of the wall, allowing for even greater visual interest. Materials and tools vary depending on the glazing method employed and number of layers desired, but the end result is nevertheless striking.

A glaze is used to change the color texture of a surface. When the emphasis is on color, a glaze refers to a layer of paint that is thinned with a medium that makes it appear transparent. In terms of altering the texture, glazing is often applied over satin and eggshell enameled decorative and ornamental plaster architecture to create a smooth, antique appearance.

The process of glazing begins with a thorough cleaning, drying, and uniform sealing of the surface. The surface is then lightly sanded to minimize imperfections and brush marks in order to improve the final appearance.

Then the glazing liquid is mixed thoroughly with a small amount of pigment. Either oil-based or water-based materials are used for glazing. The glazing liquid is then applied to the surface. It is important that the entire portion of a surface must be covered at one time. Kerosene or linseed oils are used to extend the working time of oil-based glazes. Glycerin is used to thin water-based glazes for increased working time.

After the application is made, it is partially wiped off to achieve the desired effect of antiquity.
