Hobby paint medium/additive VALLEJO 70.597 17 ml, plastic bottle, colour: Black/White

VALLEJO 70.597 is a 17 ml hobby paint medium/additive supplied in a plastic dispenser bottle and available in black and white. Designed for use with acrylic hobby paints, this medium modifies drying behavior and paint handling without altering colour consistency. It is intended to be mixed in small amounts with Model Color and similar acrylics to extend working time, enable wet-on-wet techniques and reduce skin formation on the palette while preserving the original finish and opacity control.

Advantages

This retarder medium delays drying time of acrylic hobby paints while maintaining their consistency and pigment characteristics. It is supplied in a compact plastic bottle with an applicator tip for precise dosing, allowing painters to add only a few drops where needed. The product supports controlled blending, smoother gradients and extended open time for fine-detail work on models and miniatures without significantly changing the paint’s optical properties.

Suitable for

• Model making and scale miniatures
• Miniature and figure painting (wargaming, display pieces)
• Fine-detail craft projects requiring wet blending or glazing
• Palette management to reduce skin formation and prolong open time

Key specifications

• Volume: 17 ml
• Form: liquid retarder medium for acrylic paints
• Container: plastic dispenser bottle with precision tip

• Compatibility: formulated for use with acrylic hobby paints such as Model Color

How to use

Add a few drops of the retarder medium to paint on the palette and mix thoroughly before application, or dip the brush lightly into the medium and pick up paint from the palette. Use sparingly — small amounts are sufficient to extend working time without thinning the paint excessively. Test mixtures on a scrap surface to determine the optimal ratio for the desired wetness and blending behaviour. Clean tools with water after use.

Usage recommendations

For best results, use the retarder with a limited number of drops per mix to avoid over-retarding; perform tests to find the appropriate balance for glazing, wet-on-wet blending or reducing skin formation on the palette. Store the bottle capped in a cool, dry place and shake gently before use if separation occurs.
