Pastel Ground is an acrylic preparation for pastels on canvas and other supports. It creates toothy surface similar to papers used with pastel and chalk. For an even rougher texture Fine or Coarse Pumice Gel can be added. Acrylic Ground for Pastel can also be tinted with acrylic colours.
Pastel Ground can be used as a toothy, gritty ground for many different media, including:
Dry Media | Water-based Media | Oil-based Media |
Soft Pastels | Water-Soluble Pastels | Oil Pastels |
Graphite Pencils | coloured Pencils | Oil Sticks |
coloured Chalks | Pastel Pencils | Paint Sticks |
Charcoal | Wax Crayons | Ink Sticks |
Powdered Charcoal | Watercolour Pencils | Pigment Sticks |
| Acrylic Paints | Oil Paints |
GOLDEN Pastel Ground is a 100% acrylic medium designed to prepare surfaces for the application of pastels, charcoal and other art media where a coarse tooth is desired. It contains finely ground sand (silica) in a pure acrylic emulsion.
Pastel Ground can be applied to paper, canvas, wood or any primed support. This allows almost limitless applications for media typically confined to standard papers.
Due to the weight of the solids in Ground for Pastels, it is produced very thick, and does not come ready to brush-apply. Thin 20-40% with water to desired consistency.
Apply with brush, paint-roller, spray equipment, squeegee or palette knife.
Mix up only as much as is needed for one day"s work, as the solids will settle rapidly and be extremely difficult to mix back into suspension.
For best surface adhesion, apply GOLDEN Pastel Ground over GOLDEN Gesso. It may also be applied over other GOLDEN acrylic mediums, gels, and paints for multi-media work.
Note: When used in conjunction with oil-based media, prepare support (canvas, linen, masonite, etc.) with GAC 100 to block the oil from penetrating into the support, which can weaken or rot natural fibers. See GAC Specialty Acrylic Polymer Medium Information Sheet.
Like GOLDEN Matte Medium, Pastel Ground can be used as a transparent gesso. Both can be applied directly to substrates. The "toothy" quality helps media to adhere, yet allows the underlying layers to remain visible.
Note: both products dry with a whitish translucency, and multiple applications respectively increase visibility. Test all applications prior to use.
The textural quality of Pastel Ground is similar to other GOLDEN Gels including the Pumice Gels. The grit size lies somewhere between GOLDEN Fine and Coarse Pumice Gels.
Pastel Ground can be blended with GOLDEN Acrylic Paints to achieve coloured grounds. However, add minimal amounts of colour since all additions of paint to Ground will decrease the tooth.
GOLDEN High Flow Acrylics and Fluid Acrylics blend easily into the ground without thickening the product. High Load Acrylics have the highest pigment load and therefore provide the most colour in the least amount of paint.
Unless transparency is desired, select paints that are inherently opaque, such as the Pyrroles or earth colours. This will allow lower additions as well. Airbrushing thin layers of colour after the ground has dried will give the strongest saturation of colour to the ground without affecting the gritty surface.
Adding GOLDEN Fine Pumice Gel will lower the tooth; GOLDEN Coarse Pumice Gel will increase the tooth. Experiment for varied techniques. For unusual effects, also experiment with additions of GOLDEN Micaceous Iron Oxide, Black Mica Flake, Coarse Alumina Gel and other products.
