Tamiya Acrylic Mini X-21 Flat Base

Tamiya Flat Base is an additive agent designed to turn Tamiya Gloss Bottle Paint colours into a flat finish.  Simply mix a 1:1 ratio (NEVER MORE) into a paint well palette for brush painting or an empty bottle for airbrushing. Mix well and add thinner if needed.

This agent is not a flat clear coat. It’s an agent best used for converting Tamiya Gloss Colours into a flat sheen. Mixing a ratio greater than 1:1 will yield in a milky washed-out finish.

• Small and conveniently sized 10ml bottle
• Dimensions: 44mm height x 35mm diameter

• Keep out of reach of children.
• Follow all instructions on the bottle before use.

Always use proper ventilation and personal protective equipment when painting.

About Tamiya X/XF Series Water-soluble Acrylic Paints

Tamiya Mini Acrylic (X / XF) paints are high-quality water-soluble acrylic resins in convenient 10ml mini bottles. They offer excellent flow, coverage, and blending, making them ideal for both brush painting and airbrushing on plastic models.

Key features:

• X-Series: Glossy finish — perfect for bright colors, interiors, and polished effects
• XF-Series: Flat / Matte finish — ideal for realistic military, aircraft, and weathering applications
• Easy to thin with Tamiya X-20A Acrylic Thinner (or compatible acrylic thinners)
• Water cleanup while wet; safe for most common model plastics (styrene, ABS, etc.)
• Milder solvents compared to lacquers

These acrylics are the beginner-friendly, easier-cleanup counterpart to Tamiya’s tougher Mini LP Lacquer series (similar to Mr. Hobby H-series vs. C-series). Great for all types of scale modeling — mecha, aircraft, military vehicles, cars, figures, and more.
