Using this specific product

Vallejo Surface Primer is listed here as the Acrylic-polyurethane primer version for model miniature. For using this product, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Acrylic-polyurethane primer; related versions can use different timing.
  • For model miniature, pay particular attention to the exact variant, preparation and environmental conditions.
  • At manufacturer-stated conditions; temperature, humidity and film thickness can change drying time.

How to check readiness

Check the real material or treated area at the slowest location before the next step. Confirm the surface is dry and ready before continuing. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Allow approximately 12 hours before masking. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

The first visible change is not always the manufacturer’s final-use milestone.
