Tamiya Surface Primer L Grey (87042) – 180 ml Spray

Prime your models with Tamiya 87042 Surface Primer Grey spray

A good primer for scale models is what separates an “okay” paint job from a really clean finish: better adhesion, even colour and sharp details that stay crisp.

Tamiya 87042 Surface Primer Grey is a grey spray primer (180 ml) designed for scale modelling. It works especially well on plastic (ABS/styrene) and also on metal parts, leaving a smooth, uniform base ready for paint. Its light grey tone is very useful when you are applying darker colours or want to spot small imperfections before painting.

Main features

• Improves paint adhesion and helps prevent paint from chipping or lifting.
• Thin, even coat that preserves the detail of the model.
• Suitable for plastic and metal, ideal for kits and photo-etched parts.
• Allows wet sanding to perfect the surface before painting.

When to choose grey primer

• When you are going to paint dark colours (black, greens, navy blues, intense camouflages).
• When you want an all-purpose base to check seams, filler work and panel lines.

How to apply Tamiya 87042 Surface Primer Grey (step by step)

1. Prepare the part: remove dust and grease; tidy up joints if necessary.
2. Shake the can well and spray in light coats with smooth passes.
3. Let it dry and, if needed, correct with gentle sanding.
4. Paint over it with your usual colours and finish with a varnish if you want maximum durability.

Tip: always spray in a well-ventilated area and use light passes. It is better to apply 2–3 thin coats than one heavy coat so as not to obscure the detail.
