Video: Golden Artist Colours - Gessoes & Grounds
Golden Sandable Hard Gesso is formulated with 100% acrylic dispersion polymer and can be sanded to provide surfaces that are smoother and more even than those created using regular gesso. It contains high levels of titanium dioxide, calcium carbonate, and other inert solids to produce an easily sanded surface.
Only use on inflexible substrates such as hardboard, wood or metal panels. Potential for cracking may occur if used on highly absorbent surfaces, like canvas, even when adhered to a rigid surface beforehand. Apply in multiple thin layers, gradually building up to the desired thickness. Single thick layers could crack upon drying.
When sanding, follow these general guidelines:
Brushing: This product may be diluted with up to 20% water for ease of brush application.
Spraying: Dilute Sandable Hard Gesso with Golden Airbrush Medium. Begin at a 2:1 ratio (Gesso:Medium) and test spray quality, as various spray equipment may require additional thinning. Further reduce viscosity by adding up to 20% water.
Acrylic Painting: To reduce yellowing caused by Support Induced Discoloration (S.I.D.) when painting on supports that contain water soluble impurities, such as canvas and wood panels, first apply two coats of Gloss Medium and allow to dry thoroughly. Then apply the desired number of coats of Sandable Hard Gesso.
Oil Painting: Apply oil paints to 2 or more coats of Sandable Hard Gesso.To protect natural substrates from linseed oil acids, apply 2-3 coats of GAC 100 or Gloss directly on the raw canvas first. Allow the acrylic products sufficient time to cure before applying oil paints in order to maximise mechanical adhesion
Please note: This product is designed for rigid substrates only and is NOT to be used on flexible materials, as cracking may occur.
