Hobby paint medium/additive VALLEJO 70.523 – 17 ml plastic bottle, multicolour

VALLEJO 70.523 is a 17 ml hobby paint medium/additive in a plastic dispenser bottle designed to modify the behaviour of acrylic paints for miniature and model painting. The formula improves flow, reduces surface tension and increases working time for blending, glazing and fine-detail techniques. It can be mixed in small amounts with acrylics to produce controlled translucency, smoother brushstrokes and more even washes. The supplied dispenser allows precise dosing for use in narrow areas and delicate work.

Advantages

This Vallejo medium enhances paint flow and leveling without significantly altering colour or opacity when used in recommended proportions. It supports gradual blending and glazing by extending open time and aiding even distribution of pigment on plastic, resin and metal model surfaces. The small, plastic dispenser bottle provides accurate application and easy storage for repeated hobby sessions.

Suitable for

• Miniature and figure painting where controlled translucency is required
• Model kits and scale models for smoother brushwork and washes
• Glazing, layering and blending techniques on acrylics
• Fine-detail work and touch-ups in tight areas

Key specifications

• Volume: 17 ml
• Form: liquid additive/medium
• Container: small plastic dispenser bottle for precise dosing
• Compatibility: designed for use with water-based acrylic model paints
• Function: improves flow, extends working time, aids glazing and washes

How to use

Add small amounts of the medium to acrylic paint and mix thoroughly on a palette before application. Start with low ratios and increase gradually to achieve the desired flow and translucency; excessive addition may reduce pigment strength. Apply with brush or airbrush according to the technique—washes, glazes or fine-detail strokes—and allow adequate drying time between layers. Clean tools with water immediately after use.

Usage recommendations

Use sparingly at first: a few drops per small paint quantity are usually sufficient. Test mixtures on a scrap surface to verify translucency and drying behavior. Store the bottle tightly closed and away from extreme temperatures. For reserving unpainted areas, consider using a dedicated liquid mask product that forms a removable film and can be lifted after drying.
