GESSO (White)
GOLDEN Gesso is a flexible, ready-to-use ground that prepares the surface of a substrate to accept paints and provides tooth to promote paint adhesion.

GOLDEN Gesso is a flexible liquid ground that seals, protects, and gives "tooth" to substrates, which promotes paint adhesion. It is formulated to accept a wide variety of media on many commonly used painting surfaces. It comes ready-to-use, but can be mixed with water for thinner applications. When applied in thin layers, GOLDEN Gesso will conform to a variety of textured surfaces.

GOLDEN Gesso can be brush, roller, trowel or spray-applied. Dilution of the Gesso is only necessary for spray application, but may be desired for brush or roller applications as well. When diluting with water, we recommend a maximum dilution of 25%. Any mixture within this range offers little risk of cracking or other adverse effects. Stir before use.

Generally, canvas coated with GOLDEN Gesso may be rolled up without cracking. Cracking may occur if a canvas is overly flexed or stretched, especially at colder temperatures.

Multiple Coats
Although one coat of Gesso will provide good adhesion, it may sometimes leave pinholes or uncovered areas. It is recommended to apply at least two coats of Gesso to any surface, but especially when painting on canvas or linen. The first coat will penetrate the support and reduce the likelihood of paint de-lamination. The second coat bonds with the first layer and begins to even out the surface. Subsequent layers of Gesso will produce an even smoother surface. For spray-application, you may have to apply more than 2 coats to achieve a film similar to a brush application.

Spray Application Dilutions
The degree to which the GOLDEN Gesso needs thinning depends on what type of spray equipment is being used. No dilution of the Gesso may be required when using equipment with relatively large orifices and substantial pressure. Thin Gesso for spraying by blending with GOLDEN Airbrush Medium, which reduces viscosity, improves flow and tip-dry, and promotes leveling. Start with a mixture of 1 part Airbrush Medium to 1 part Gesso and test spray quality. Additional reduction with the Airbrush Medium may be required, especially with smaller nozzle equipment and lower air pressures.

While sanding GOLDEN Gesso is possible, the heat generated in the process will "gum up" the sandpaper rather quickly. Wet sanding will give very good results while reducing dust production.

Use With Oil Paints
Oil Paints can be applied directly over acrylic Gesso. There is adequate adhesion due to the porosity of the acrylic. To control the penetration of linseed oil into canvas, apply at least three coats of Gesso.
