Primer spray Army Painter GM3005P, base primer for miniatures and models, ready-mixed 0.3 L

Army Painter GM3005P is a ready-mixed base primer spray formulated for use on miniatures, scale models and terrain pieces. Supplied in a 0.3 L aerosol can, this primer creates an even matt base layer that improves paint adhesion and coverage on common modelling substrates such as MDF, polystyrene and XPS foam. The water-based formulation is non-corrosive and low-odor, allowing hobbyists to prime components for both acrylic and enamel painting without damaging delicate materials.

Advantages

This primer provides uniform surface coverage and a matt finish that enhances subsequent paint application and shading. Its ready-mixed spray format saves time compared with brush-on primers and reduces the risk of clogging fine model details. The water-based composition is non-toxic and non-corrosive to common modelling materials, and the formulation promotes reliable adhesion for basecoat layers, improving final paint durability and appearance.

Suitable for

• Priming miniatures and figurines before acrylic or enamel painting
• Preparing scale model kits and assembled sub-assemblies
• Priming terrain elements made from MDF, polystyrene or XPS foam
• Applying a uniform basecoat to multiple small parts and sprues

How to use

Shake the can thoroughly before use to ensure even dispersion of pigments. Work in a well-ventilated area and keep a consistent spray distance of approximately 20–30 cm from the model surface. Apply thin, even coats using smooth sweeping passes to avoid pooling and loss of detail; allow each coat to dry before applying additional layers. Test-spray on a scrap piece to confirm coverage and color match before spraying finished models.

Usage recommendations

For best results, clean and remove dust from surfaces prior to priming. Mask areas that should remain unprimed. When priming fine details, use light passes and allow adequate drying time between coats. Store the can upright in a cool, dry place and follow local disposal regulations for aerosol products.
