Primer base paint VALLEJO 70.604 0.017 L — ready-mixed primer for metal, plastic, PVC

VALLEJO 70.604 is a ready-mixed base primer in a 0.017 L bottle formulated to prepare surfaces such as metal, plastic and PVC before painting. The primer creates a uniform, adherent base layer that preserves fine model details while improving the adhesion of subsequent paints and finishes. Its fast-drying formula forms a homogenous, strong film within hours and is supplied in a compact pack suitable for model making, small repairs and targeted surface preparation tasks.

Advantages

This ready-mixed primer provides consistent coverage and retains the smallest sculpted or cast details on models and miniatures. It is compatible with common modelling substrates including resin, PVC, brass, white metal and wood, and may be applied directly from the bottle or thinned for airbrush use. The product dries quickly to a durable, even film that improves paint adhesion and reduces the need for multiple corrective coats.

Suitable for

• Preparing metal surfaces prior to acrylic or enamel painting
• Priming plastic and PVC model kits and miniatures
• Small repair jobs and spot priming on dioramas or scale models
• Use as a base layer before detailed hand-painting or airbrushing

Key specifications

• Form: ready-mixed liquid primer
• Volume: 0.017 L
• Compatible substrates: metal, plastic, PVC, resin, brass, white metal, wood
• Application methods: brush or airbrush (may be thinned)
• Drying: fast-drying to a homogenous film within hours

How to use

Ensure the surface is clean, dry and free of dust, grease or mold release agents before application. Apply the primer in thin, even coats to avoid obscuring fine details; allow each layer to dry before applying the next. For airbrush application dilute with a suitable thinner such as Vallejo Airbrush Thinner or Flow Improver and follow recommended compressor settings of approximately 15–20 PSI (0.5–1 kg). For brush application apply light, controlled strokes and avoid heavy loading of the brush.

Usage recommendations

For consistent airbrush performance clean the tool after use with an appropriate airbrush cleaner and maintain recommended compressor pressures. Apply several thin coats rather than one heavy coat to preserve surface detail. When thinning, use the manufacturer’s recommended thinners and test on a spare piece to confirm flow and coverage before working on the final model.
