What is a spray primer and why is it essential?

A spray primer, also known as an undercoat, is the absolute foundation for preparing a model for painting. It's a special type of paint applied as the first layer directly onto plastic, resin, or metal surfaces. Its primary purpose is to create an ideal surface for subsequent layers of acrylic or enamel paints to adhere to. Thanks to the primer, the main coat of paint adheres much better to the model, preventing it from chipping or rubbing off. This is the key to a durable and professional finish.

Additionally, a primer unifies the color of the entire model. Whether you are assembling a model from parts of different colors, applying a primer gives the entire piece a single, consistent color. This not only makes painting easier but also helps to reveal any imperfections, such as scratches, seam lines from gluing, or uneven surfaces, which can be corrected before applying the final color.

How to choose and apply a model spray primer?

Choosing the right primer depends on the effect you want to achieve. The most popular choice is a gray primer, which provides a neutral base for most colors. A white primer is perfect for bright and vibrant colors (like yellows and reds), as it enhances their saturation. Conversely, a black primer is ideal for dark shades or as a base for the pre-shading technique, which helps create effects of shadow and depth.

Our selection includes spray primers from leading model-making chemical manufacturers, guaranteeing excellent quality and a fine pigment that won't obscure details. Application is simple – just shake the can well and apply the paint in short, smooth strokes from a distance of about 20-30 cm to achieve a thin, even coat.
