Micro Coat Flat

Micro Coat Flat: the matte finish that withstands the test of time and the real handling of the modeller

When a model passes through many hands —whether on display, in competition, or simply on the workbench— the finish ends up being the first affected. Micro Coat Flat (ref. CH64003) solves that problem with a formulation of water-based acrylic resin that not only provides a high-quality matte finish but also maintains its appearance intact after being handled time and time again.

What is Micro Coat Flat and what is it for?

Micro Coat Flat is a matte finishing varnish from the MICRO line, designed for both static models and figures and dioramas. Its main function is twofold:

• To protect the underlying paint layer from wear, handling, and the passage of time.
• To prepare the model's surface to receive decals with maximum realism, eliminating the silvering effect and promoting perfect adhesion.

The resin used is the same as that employed across the entire MICRO range: acrylic, water-soluble, transparent when dry, flexible, and with notable adhesion to both paint and directly to plastic.

Main features

• Durable matte finish: retains its appearance even after continuous handling, without the surface becoming shiny due to contact.
• Water-based acrylic base: easy to clean, low toxicity, and compatible with common modelling workflows.
• Flexible resin: does not crack or chip over time, ensuring long-term protection.
• High adhesion: adheres firmly to paints of different bases and to plastic surfaces.
• Mixable: can be combined with other finishes from the MICRO range to achieve intermediate levels of gloss, or diluted with water in small amounts to adjust viscosity.
• Durability: according to the manufacturer, it can remain in optimal conditions for at least 20 years under ordinary conditions.

Applications in modelling

Micro Coat Flat fits perfectly into various stages of the construction and finishing process:

1. Pre-decal layer: applied before decals, it seals the paint and creates a homogeneous surface that prevents the silvering effect. It is the recommended step to ensure that decals are integrated naturally.
2. Final protective layer: once the decals and filters or washes are applied, a coat of Micro Coat Flat unifies the finish and protects all previous work.
3. Figures and dioramas: in miniatures and miniature scenes, the matte finish is the most common to avoid unwanted reflections that betray the scale. Micro Coat Flat performs excellently here.

Application tips

• Apply in thin layers. One or two coats are usually sufficient; very thick layers can generate slight cloudiness.
• Shake the bottle well before use to homogenise the resin.
• It can be applied with a soft-haired flat brush or with an airbrush, slightly diluted with distilled water.
• Allow to dry completely between coats and before applying decals or pigments.
• If you are looking for an intermediate finish between matte and satin, mix Micro Coat Flat with Micro Coat Satin from the same range until you achieve the desired level of gloss.

Compatibility

Micro Coat Flat is compatible with acrylic-based paints such as those from Vallejo, Tamiya, Ammo, or Kaleido, as well as with cured enamels. On unprimed plastic surfaces, it also offers good adhesion, although it is always advisable to apply a primer coat first to ensure the durability of the finish.

Frequently asked questions

Can I use Micro Coat Flat directly on unpainted plastic?

Yes, the acrylic resin of Micro Coat Flat adheres to plastic. However, for long-lasting work or models that will be frequently handled, we recommend applying a primer coat first to maximise adhesion and durability of the finish.

Is it necessary to use Micro Coat Flat before applying decals?

It is not strictly mandatory, but it is highly recommended. A sealed and homogeneous surface —which can be achieved with Micro Coat Flat or a prior satin varnish— prevents the silvering effect around the decals and facilitates their positioning. It is the most common method among the most demanding modellers.

Can I mix Micro Coat Flat with other finishes from the MICRO range?

Yes. The manufacturer expressly states that MICRO finishes are mixable with each other. If you want a result between matte and satin, combine Micro Coat Flat with Micro Coat Satin in the proportion that suits your preference.

What should I use to clean the brush or airbrush after using Micro Coat Flat?

Being a water-based acrylic formulation, cleaning is straightforward with water, especially while the product is still fresh. Once dry, it may require water with a few drops of soap or a specific cleaner for acrylics.

How many coats do I need to apply?

In most cases, one or two thin coats are sufficient. Applying layers that are too thick or in very humid environments can generate slight cloudiness. The optimal approach is to work in thin layers and allow them to dry well between applications.

Is it suitable for airbrush application?

Yes. You can dilute it slightly with distilled water to adjust the viscosity to your airbrush flow. Work with low pressure and at a medium distance to achieve an even layer without accumulations.

Micro Coat Flat (CH64003) is a water-based matte acrylic varnish designed for scale models, static kits, figures, and dioramas. Its flexible and durable acrylic resin bonds firmly to paint and plastic surfaces, providing long-lasting matte protection even under frequent handling. It is the ideal choice for sealing surfaces before applying decals, eliminating silvering and ensuring a flawless, realistic finish. Compatible with Vallejo, Tamiya, and Ammo acrylic paints, and mixable with other Micro Coat finishes to achieve custom sheen levels. A trusted reference in scale modelling finishing products.
