Primer Vallejo Acrylic-Polyurethane Yellow 73604 – acrylic-polyurethane primer, yellow shade

Primer Vallejo Acrylic-Polyurethane Yellow 73604 is an acrylic-polyurethane primer in a yellow shade from VALLEJO designed to create a stable, even base for subsequent paint layers. Intended for use on plastic, resin, metal and other common modeling materials, this primer improves paint adhesion and enhances color consistency for both acrylic and enamel topcoats. The formulation balances quick drying with durable film formation, providing a workable surface for detailed scale models and miniatures.

Advantages

This acrylic-polyurethane primer offers reliable adhesion to a variety of hobby surfaces and forms a uniform, even yellow undercoat that helps subsequent colors read accurately. The product dries to a consistent finish that reduces surface imperfections and supports fine-detail painting. Its compatibility with both acrylic and enamel paints makes it a versatile choice for different hobby workflows. The primer is formulated to produce a durable film that withstands handling during assembly and painting stages.

Suitable for

• Scale models and miniatures requiring a coloured undercoat
• Plastic, resin and metal surfaces used in modeling and hobby projects
• Preparatory priming before acrylic or enamel topcoats
• Projects where even coverage and color control are important

How to use

Ensure the surface is clean, dry and free of grease or release agents prior to application. Shake the container thoroughly to homogenize the pigment and binder. Apply the primer in thin, even coats by brush, airbrush or spray, allowing adequate drying time between coats to avoid runs or pooling. For best results on models and miniatures, apply multiple light passes rather than a single heavy coat to preserve fine details. Once fully dry, the surface can be sanded lightly if necessary and is ready for subsequent acrylic or enamel painting.

Usage recommendations

Work in a well-ventilated area and use appropriate personal protection when spraying or applying multiple coats. Test compatibility with specific paints and materials on a small area before full application. Store the primer in a cool, dry place away from direct heat sources and tightly close the container after use to maintain product quality.
