GOLDEN High Flow Acrylics (HFAs) are professional artist grade acrylic paints. HFAs may be used whenever a thin paint is required. This Product Information Sheet provides some general suggestions and starting points for specific applications, but each artist will develop their own methods and processes as needed
- General Thinning Instructions: Avoid thinning with water more than 20% by volume when using in pens and airbrushes, or when doing applications on non-absorbent surfaces. Use Airbrush Transparent Extender for high levels of thinning/extending.
- Blends with other GOLDEN Products:
NOTE: HFAs contain retarders which alter the drying times of a mixture; thicker paint layers may remain tacky for long periods of time.
GOLDEN HFAs are compatible with most GOLDEN Artist Colors’ paints and mediums. They can be added to GOLDEN Heavy Body Acrylics or GOLDEN Fluid Acrylics to thin the paint without a loss of pigment or film strength. Extend HFAs with GOLDEN Airbrush Transparent Extender as needed. Adding high levels of water are acceptable when doing color stains on absorbent surfaces but additional layers of acrylic medium applied afterword may be required for long term durability.
- Use as colorant/tint: As with any GOLDEN paint, HFAs may be used to add color to gels, mediums and pastes. They blend readily with thinner mediums, such as GOLDEN Acrylic Glazing Liquid, or GOLDEN Polymer Medium (Gloss).
Paint Sensitivity Timelines: The HFAs may require additional time to dry before applying other paints or mediums over them, especially if those materials contain retarders. Allow for HFAs to dry sufficiently to avoid sensitivity issues. In most applications the waiting period is several minutes.
Isolation Coats and Varnishing: Allow 12-24 hours for the HFA layers to dry before applying isolation coats or varnish layers. Some colors, such as the Fluorescent Colors, can take longer to fully cure than others. Test the process to identify the amount of time to wait for drying or which mediums can be more problematic than others.
