VALLEJO Chipping Medium hobby paint medium/additive 35 ml plastic bottle

VALLEJO Chipping Medium is a 35 ml hobby paint medium supplied in a plastic bottle and formulated to produce realistic paint chipping and wear effects on scale models and dioramas. Applied between paint layers, this additive creates a weakly adherent intermediate film that allows controlled removal of the topcoat with water and a brush or toothpick, revealing the underlying base color and simulating natural surface aging on plastic and metal model parts.

Advantages

The medium provides predictable and repeatable chipping results when used as an interlayer between primers, base colors, and topcoats. It is supplied in a convenient 35 ml plastic bottle that is easy to handle during model preparation. The formula is compatible with common hobby paints and enables fine control over chip size and placement by varying application thickness and removal technique. It does not require heat or solvents to create chips; gentle rubbing with water is sufficient to expose the base layer where desired.

Suitable for

• Creating realistic paint chips on scale plastic models (vehicles, aircraft, figures)
• Simulating wear and rusted or worn paint on metal model parts
• Adding weathering details on dioramas and miniatures
• Controlled restoration or modification of painted surfaces for hobby projects

Key specifications

• Volume: 35 ml
• Packaging: Plastic bottle with screw cap for controlled dispensing
• Type: Chipping medium / paint additive for interlayer application
• Compatibility: Designed for use with standard hobby paints on plastic and metal surfaces
• Application method: Brush application between paint layers; removable with water and mechanical action

How to use

Apply a thin, even coat of the chipping medium over a fully cured base layer and allow it to dry according to ambient conditions. Once the medium is dry, apply the topcoat paint and let it dry partially or fully depending on the desired chipping behavior. To create chips, moisten the topcoat with water and gently rub with a stiff brush, cotton swab, or toothpick until the underlying base color appears. Varying the thickness of the medium, the drying time of the topcoat, and the removal technique will produce different chip sizes and patterns.

Usage recommendations

For best results, test the product on a scrap piece painted with the same primer, base color, and topcoat to set the preferred application thickness and removal method. Avoid using aggressive solvents or excessive mechanical force to prevent damage to delicate parts. Store the bottle upright in a cool, dry place and ensure caps are closed tightly to prevent drying out.
