Tamiya Mark Fit: the ally for decals to conform as if they were paint

Getting a decal to adhere completely to the contours of a model, without wrinkles, raised edges, and without that "floating sticker" appearance, is one of the classic challenges of static modelling. Tamiya Mark Fit (TA87102) is the softening liquid specifically designed for this purpose: it softens the decal emulsion so that it moulds to the surface as if it were part of it.

Main features

• Water-based decal softener formulated by Tamiya for use on static models, figures, and dioramas.
• Facilitates adaptation to curved and rounded surfaces — hoods, fuselages, figure bases — where decals tend to wrinkle.
• Improves adhesion on matte or satin finishes, where decals typically encounter more difficulties.
• Helps eliminate micro-bubbles of air and allows the decal to settle properly on areas with relief or irregular texture.
• 40 ml bottle with an integrated brush in the cap, allowing for direct and controlled application without the need for additional tools.

Application method

1. Apply a layer of Mark Fit over the area of the model where you will place the decal.
2. Place the wet decal over that area using the usual technique.
3. Apply a second layer of Mark Fit over the already positioned decal.
4. With a soft cloth or a cotton swab, gently press to remove excess liquid and adjust the decal to the surface.
5. Allow to dry completely before applying a finishing varnish.

Usage tips

For surfaces with pronounced curvature, apply the product in two or three thin layers instead of one thick layer. If the decal shows wrinkles as it dries, a gentle reapplication with the brush usually resolves the issue without the need to remove it. On matte or satin finishes, combining Mark Fit with a prior layer of glossy varnish beneath the decal significantly improves the final result and prevents the "silvering" effect (whitish halos around the decal).

Ideal for…

Modellers working with static models of vehicles, aircraft, boats, or figures who need to place decals accurately on complex surfaces. It is also very useful in the decoration of miniatures and dioramas where the quality of the final finish is crucial.

Frequently asked questions

What is the difference between Mark Fit and Mark Softer from Tamiya?

Tamiya markets several versions of its decal liquid. Mark Fit is the standard formula, suitable for most surfaces and decals. Mark Softer has a more aggressive action and is recommended for particularly rigid decals or surfaces with very pronounced reliefs. For general use, Mark Fit is the safest starting option.

Can Mark Fit be used on any type of paint?

Yes, it is compatible with common finishes in modelling: acrylics, enamels, and lacquers from brands like Tamiya, Vallejo, Kaleido, or Ammo, as long as the paint layer is properly cured. It is recommended to apply it over a layer of glossy varnish for better results, especially on matte surfaces.

Does the liquid damage the decal if applied excessively?

An excess of product can soften the decal too much and hinder its handling. The ideal is to apply moderate layers and allow each to act before repeating the operation. With careful application, the risk of damaging the decal is minimal.

How long does it take to dry?

Drying time varies depending on temperature and humidity, but under normal conditions, the decal settles in 15-30 minutes. Before applying the finishing varnish, it is advisable to wait at least an hour to ensure that the adhesion process is complete.

Does the 40 ml bottle include a brush?

Yes, the bottle cap incorporates an integrated brush, allowing the product to be applied directly without the need for a separate brush. It is one of the practical details that make this format a convenient solution for the workbench.
