About this product:

• GOLDEN GAC 900 is a liquid acrylic medium that is blended with artist acrylics to create fabric paints intended to be applied to fabrics, textiles, and garments that need to hold up to repeated laundering cycles;
  
• This heat-set fabric painting medium offers a very soft hand and laundering stability;
  
• Mix with High Flow Acrylics to produce "tie-dye" effects, or blend with GOLDEN Heavy Body, Matte or Fluid Acrylics for brush or screen application.

How to use:

• GAC 900 is designed to be blended with standard artist acrylic paints, such as GOLDEN Heavy Body Acrylics. Start at a 1:1 mixing ratio of paint to GAC 900, and adjust as needed to modify the consistency for the type of paint application you intend to do. The amount of GAC 900 may also be increased to improve softness of hand (such as when working on delicate fabrics).
  
• Apply the paints as desired and allow the paint to dry well before heat-setting. Air dry time can vary between 1 and 4 hours for most applications, but longer times are usually preferred when practical, then heat-set the garment.
  
• Heat-setting is necessary to fuse the GAC 900 into the fabric and improve the “hand” or softness of the laundered garment. Properly heatset the painted areas by following the temperature and duration recommendations. The temperature setting and heating duration impact how well the paints will remain in the garment during repeated wash/dry cycles. ALWAYS TEST TO BE SURE THE DESIRED TEMPERATURE AND DURATION DO NOT RUIN THE FABRIC OR THE PAINTED SECTIONS.
  
• The time needed to heat-set GAC 900 depends on the temperature and duration. Higher temperatures set faster, but some fabrics may require lower heat.
  
• Heat-setting releases low levels of formaldehyde. Ensure proper ventilation - use a vented dryer, or when using an iron or heat press, work near a fan with fresh air.
  
• Clothes irons, dryers, and heat presses can be used, but the temperature may need adjustment depending on the fabric and acrylic products.
