1. Introduction
The GOLDEN Retarder is an acrylic fluid medium additive designed to extend the open (drying) time of acrylic paints. This allows artists more time for blending, wet-in-wet techniques, and reduces the tendency for paint to skin over on the palette. It is suitable for professional artists and enthusiasts seeking greater control over their acrylic painting process.

2. Safety Information
Always read the product label for specific safety instructions before use. While GOLDEN Retarder is generally safe for art applications, observe the following precautions:
- Keep out of reach of children.
- Avoid ingestion. If swallowed, seek medical attention immediately.
- Use in a well-ventilated area.
- Avoid prolonged skin contact. Wash hands thoroughly after use.
- Store in a cool, dry place, away from direct sunlight and extreme temperatures.
3. Setup and Preparation
Before using the GOLDEN Retarder, ensure your workspace is clean and organized. Prepare your acrylic paints and palette as usual.
- Shake Bottle: Gently shake the GOLDEN Retarder bottle before each use to ensure consistent product composition.
- Prepare Paints: Dispense your desired acrylic paints onto a clean palette.
- Ventilation: Ensure adequate ventilation in your working area.
4. Operating Instructions
The GOLDEN Retarder is designed to be mixed directly with acrylic paints to extend their working time. The amount used will depend on the desired effect and environmental conditions.
4.1. Mixing with Acrylic Paints
- Start Small: Begin by adding a very small amount of Retarder to your acrylic paint. A few drops are often sufficient for a small puddle of paint.
- Mix Thoroughly: Use a palette knife or brush to thoroughly mix the Retarder into the paint until it is evenly incorporated.
- Test: Test the paint on a scrap surface to assess the extended drying time. Adjust the amount of Retarder as needed.
- Recommended Ratio: Do not exceed a 1:1 ratio of Retarder to paint. Using too much Retarder can compromise the paint film's integrity, adhesion, and drying properties.
4.2. Application Techniques
- Wet-in-Wet Blending: The extended open time facilitates seamless blending of colors directly on the canvas, allowing for smooth transitions and gradients.
- Palette Management: Mixing Retarder into paints on your palette helps prevent premature drying and skinning, reducing paint waste and allowing longer working sessions.
- Rejuvenating Paint: A small amount can be used to re-work paint that has started to dry on the palette or in the tube, making it pliable again.

5. Maintenance
Proper storage and handling will ensure the longevity and effectiveness of your GOLDEN Retarder.
- Storage: Store the bottle upright in a cool, dry environment, away from direct sunlight and freezing temperatures. Ensure the cap is tightly sealed after each use.
- Cleaning: Clean any spills immediately with water. Tools used with Retarder can be cleaned with soap and water before the product dries.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Paint not drying or remaining tacky | Too much Retarder added to paint. | Reduce the amount of Retarder in future mixes. For existing work, allow significantly more drying time in a well-ventilated area. |
| Retarder leaking from bottle | Cap not securely closed or bottle stored improperly (e.g., on its side). | Ensure the cap is tightly sealed after each use. Store the bottle upright. |
| Paint film appears weak or brittle | Excessive use of Retarder, exceeding recommended ratios. | Adhere to the recommended maximum 1:1 ratio of Retarder to paint. For best results, use sparingly. |
