Sepia Filth Wash 18ml

Sepia Filth Wash (AK19305) is a water-based acrylic wash from the Master Acrylic Wash range by AK Interactive, specifically formulated for inking, pin washing and shading on scale models, wargame miniatures and figures. Its Sepia Filth tone adds warm depth to recesses, crevices and details without hardening colours excessively, making it ideal for bright colour schemes and realistic results without excessive contrast. Particularly effective over flesh tones, skulls, skeletons and bone surfaces, giving them an aged appearance with a warm, natural touch. Available through Feroca, official distributor of AK Interactive in Spain.

Technical specifications

What it is used for

Sepia Filth Wash is designed to add depth, shadow and contrast in areas that are difficult to reach with a conventional brush, without hardening the overall colour scheme. Its fluid viscosity allows the product to flow naturally into the lowest parts of the surface, doing the work in a controlled and effortless way. It is particularly effective in the following contexts:

• Shading flesh tones on historical and fantasy figures, accentuating wrinkles, eyes and muscles with a warm, natural touch
• Ageing skulls, skeletons and bone surfaces to give them a worn, time-worn appearance without looking dirty
• General shading of wargame miniatures with bright colour schemes where realistic depth is sought without excessive contrast
• Pin washing on panels, joints and bolts of scale models where a warm, subtle shadow tone is required
• Inking leather, wood, rope and organic texture details on historical miniatures and diorama figures
• Dioramas and fantasy settings where the warm sepia tone enhances aged materials, desert environments and earth-toned surfaces

How to use it

1. Shake the bottle well: before use, shake the bottle for 30–60 seconds to homogenise the pigment with the acrylic medium.
2. Apply with a fine brush: load a fine or medium-tipped brush and deposit the wash directly onto the area to be treated (recesses, crevices, joints). For general shading, spread it over the entire piece with a soft flat brush.
3. Let it flow and work: gravity and surface tension carry the product into the details. If excess remains on flat areas, remove it with a clean, slightly damp brush before it dries.
4. Drying time: allow to dry completely at room temperature (approximately 20–30 minutes depending on the amount applied and ambient conditions).
5. Cleaning: clean the brush with running water immediately after use. If the product has dried on the brush, use an acrylic brush cleaner.

Tips and tricks

Control the amount of product

Overloading the brush can cause unwanted stains on flat areas and make corrections difficult. Work with small amounts and build up the effect progressively, especially when applying the wash over large surfaces with few details.

Combine with other tones for advanced effects

Sepia Filth works particularly well in combination with darker or neutral washes in transition areas. Apply a darker tone first in the deepest parts and use Sepia Filth in the intermediate areas to simulate the reflection of a warm ambient light, very common in desert, historical or fantasy settings.

Temperature and humidity matter

In very humid or cold environments the drying time increases. In very dry or hot environments the wash may dry before it has had time to flow correctly into the details. Work in ventilated spaces at a moderate temperature and, if necessary, add a few drops of distilled water to adjust the fluidity without altering the formulation.
