Product Description
GOLDEN Gesso is a flexible, ready-to-use acrylic dispersion ground that prepares a substrate or surface to accept paints by providing “tooth” to promote paint adhesion.
Key Features
- Semi-opaque waterborne acrylic dispersion ground
- Available in Black and White
- Suitable for acrylic and oil paints (and many other media)
- Dries Satin to Matte in sheen
- Water clean-up
Application
- Stir before use; some settling is expected
- Ready to use; can be thinned with water up to 25%
- Appropriate on canvas, panel and various acrylic-receptive surfaces
- Can be brush, trowel, or spray-applied (rolling may produce foam)
- Allow 1 -3 hours between applications, depending upon environment
- Can be mixed with GOLDEN Acrylics to produce range of colored grounds
- Gesso can be modified with most GOLDEN Gels & Mediums to increase flexibility, lower tooth and absorbency
- Thin applications are recommended, thick single-applications may crack
- Thin applications can conform to a variety of textures without cracking
- For indoor use only
- Always test before your application for best results
Storage
Store in a cool/dry location at temperatures above 50° F, ideally between 60° F & 90° F. Avoid repeated freezing and thawing as well as exposure to temperatures exceeding 120° F for extended periods.
Clean up
Clean your skin and equipment immediately after use with soap and warm water. Consult with local authorities for methods of disposal or see information on Cleaning Your Acrylic Waste Water Made Easy!!
Handling and Transportation
Gesso may be susceptible to cracking if a canvas is overly flexed or stretched, especially at colder temperatures. For more information about handling and transporting paintings, please refer to Handling and Transportation of Acrylic Paintings and Rolling Acrylic Paintings for Shipping or Storage
Technical Information
- Resin:
- Methylmethacrylate/butylacrylate copolymer dispersion polymer
- Vehicle:
- Water
- Pigment Identification:
- PW6 (White Gesso); PBk7 & PBk11 (Black Gesso)
- Lightfastness:
- Lightfastness rated I (per ASTM D 5098)
- Permanency:
- Excellent
- Opacity:
- Semi-Opaque
- Viscosity:
- 3,000 - 4,000 cPs (as measured on a Brookfield RV viscometer)
- pH:
- 8.4 - 9.0 (slightly alkaline)
- Gloss:
- White: 5.0 - 10.0; Black: 1.5 - 5.0 (using a 75° Glossmeter)
- Flexibility:
- ASTM D522, Test Method B-Cylindrical Mandrel Test at 70°F, 6 mil thick film passes at 1/4" diameter mandrel. Adequate flexibility to withstand loose rolling and re-stretching at room temperature. Paint films become more brittle below 50°F, and should not be bent, stretched or flexed under such conditions. Withstands expansion and contraction caused by changes in temperature and humidity.
- Drying/Curing Time:
- A 10 mil wet film will dry to touch within 2 hours when the temperature is above 65°F and humidity is below 70%. Thicker films cure much more slowly. Lower temperatures and/or higher humidity slow the drying process considerably.
