Primer VALLEJO VA73643 60 L — ready-mixed coloring primer for plastic

VALLEJO VA73643 60 L is a ready-mixed coloring primer formulated specifically for plastic surfaces. Supplied in a 60 L volume, this primer evens out substrate appearance and provides a uniform base layer that improves adhesion of subsequent paint systems. It is intended for use on plastic model parts, prototypes and various plastic components encountered in hobby, modeling and professional finishing tasks.

Advantages

This coloring primer is ready to use and does not require mixing, which reduces preparation time and ensures consistent coverage across larger batches of plastic parts. Its formulation promotes good adhesion to common plastics used in model making and prototyping while creating an even surface that reduces the visibility of seams and minor imperfections. The primer provides a stable base layer suitable for a wide range of topcoat paints and finishing techniques.

Suitable for

• Plastic model kits and scale models
• Prototypes and 3D-printed plastic parts
• Plastic components in hobby and small-scale professional projects
• Surface preparation before airbrushing or brush painting

Key specifications

• Formulation: ready-mixed coloring primer for plastics
• Volume: 60 L container
• Primary function: even out substrate appearance and improve paint adhesion
• Compatibility: designed for use on common plastic materials used in models and prototypes
• Finish: matt base suitable for subsequent paint layers

How to use

Ensure plastic surfaces are clean, dry and free of oils, dust and release agents before application. Apply the primer at recommended ambient conditions and follow safe ventilation practices. Use an appropriate spraying method or application tool for the product volume and part geometry; apply thin, even coats and allow adequate flash-off time between layers to prevent runs. After the primer is fully dry, proceed with sanding or surface adjustment if needed, then apply the chosen topcoat.

Usage recommendations

For best results on plastic, degrease parts with a suitable cleaner and perform a light abrasion where needed to enhance mechanical keying. Test the primer on a small sample piece before full-scale application to confirm compatibility with the specific plastic type and intended topcoat paints.
