Get a True Flat with Tamiya 81021 Acrylic X-21

The Tamiya 81021 Acrylic X-21 Flat Base is crafted for modellers who want a low-sheen finish. This 23ml bottle contains a water-soluble flat base compatible with styrol resins, Styrofoam, wood, and most conventional modelling plastics.

Techniques for Smooth Flat Coats

Use X-21 mixed into other Tamiya acrylics for even mattification whether brushing or airbrushing. When airbrushing, thin with recommended Tamiya thinners like 81020, 81030, 81040, 81520, or 87077 to get a consistent spray pattern.

Materials and Typical Applications

This flat base suits a variety of projects from scale kits to dioramas, helping reduce gloss without altering colour tone significantly. Its water-acrylic composition also makes handling and cleanup easier for workshop use.
