Quick Answer
Salt streaks weathering uses salt or salt-paste to create white, crystalline streaks that mimic salt deposits on ship hulls and superstructures. Apply a dark wash or pigment, then add salt for texture, and seal with a matte varnish. For best results, use products like Mr. Weathering Color to control the effect.
Salt streaks are one of the most distinctive signs of a ship that has spent time at sea. They form where seawater evaporates, leaving white lines running down from fittings, hatches, and scuppers. Recreating them on a model adds instant realism, but many builders struggle to make them look natural rather than like splattered paint.
This guide walks you through a reliable salt-streak technique that works on both plastic and resin ship models. You will learn how to layer weathering products, control the intensity, and avoid the most common mistakes. By the end, you will have a ship that looks like it just returned from a long voyage.
Why Salt Streaks Matter for Ship Realism
On a real ship, salt streaks appear as white or light gray lines that follow gravity. They are most visible on dark hulls and superstructures, especially after a storm or in cold climates. Adding them to a model helps tell the story of a vessel that works hard, not a clean display piece.
The key to realistic salt streaks is subtlety. They should vary in length, width, and intensity. Some streaks will be crisp, others will fade out. A good technique uses multiple layers and allows you to build up the effect gradually.
- Study reference photos of real ships to see where salt accumulates: below railings, around scuppers, and under overhangs.
Materials You Will Need
For this technique, you need a base coat (usually a matte or satin finish), a dark wash or panel liner, a white or light gray pigment or paint, and a matte varnish to seal everything. A fine brush and a small container for mixing are also essential.
Mr. Weathering Color WC01 - Multi Black is a versatile dark color that works well for creating the initial grime and shadowing around the areas where salt will appear. It can be used on its own or mixed with other colors to adjust the brightness, giving you control over the contrast.
For the white salt streaks, you can use white pigment or a light gray acrylic paint. Some modelers use fine table salt or sea salt as a texture, but you can also create streaks purely with paint. The choice depends on how much physical texture you want.
- Use a matte varnish before applying the salt streaks so the paint adheres well and does not bead up.
Preparing the Surface
Before you start, make sure your model is clean and free of dust. If you have applied decals, seal them with a gloss coat first, then apply a matte coat for the weathering. A matte surface gives the wash and pigments something to grip.
Mask off areas that should stay clean, like windows or polished metal. You can use low-tack tape or liquid mask. This step is often skipped, but it saves you from having to clean up later.
- Check that the base coat is fully cured before starting the weathering process.
Applying the Dark Wash and Shadowing
Start by applying a dark wash to the areas where salt streaks will appear. This creates a shadow behind the white streaks, making them pop. Use a fine brush to draw thin lines downward from edges, hatches, and other details.
Mr. Weathering Color WC01 - Multi Black is ideal for this step because it is oil-based and can be adjusted. You can mix it with a thinner or other colors to create a lighter gray for subtle shadowing. Work in small sections and blend the edges with a dry brush or sponge.
Let the wash dry completely before moving on. This can take several hours, depending on the product and the thickness of the application.
- Do not apply the wash too thickly, or it will look like a solid black line instead of a shadow.
Creating the Salt Streaks
Now it is time to add the white salt streaks. You have two options: use a fine brush to paint thin lines, or use a salt-paste technique. For the paste, mix white pigment or light gray paint with a little water or acrylic medium to make a thick paste. Apply it with a brush, then use a toothpick to create streaks.
For a more realistic effect, vary the opacity. Some streaks should be solid, while others should be semi-transparent. You can achieve this by thinning the paste or by dabbing with a sponge. Work from the top down, letting gravity guide the direction.
If you make a mistake, you can remove the paint with a damp brush or cotton swab before it dries. If it dries, you can scrape it off with a hobby knife, but be careful not to damage the base coat.
- Use a reference photo to get the direction and length of streaks right.
Sealing and Protecting the Effect
Once you are happy with the salt streaks, let them dry completely, then seal them with a matte varnish. This protects the weathering from handling and future coats. Use a spray varnish for an even finish, or brush on a thin coat if you prefer.
The varnish will also unify the look, blending the streaks with the base coat. If you want a glossy finish in some areas, you can apply a gloss coat selectively, but a matte finish is usually best for a weathered ship.
- Test the varnish on a scrap piece first to ensure it does not react with the paint underneath.
Step-by-Step Salt Streaks Process
- Apply the dark wash: Use a fine brush to apply Mr. Weathering Color WC01 - Multi Black or a similar dark wash to areas where salt will accumulate. Create thin, downward lines from edges and details. Checkpoint: Ensure the wash is not too thick; blend edges for a soft shadow.
- Let it dry completely: Wait for the wash to dry thoroughly. This can take a few hours. Do not rush, as the salt streaks will not adhere properly if the wash is still wet. Common mistake: applying salt streaks too soon; the paint will mix and create a muddy look.
- Create the salt streaks: Mix white pigment or light gray paint with a little water or medium to make a paste. Apply it with a brush, using a toothpick to create natural streaks. Vary the opacity for realism. Checkpoint: Work from top to bottom, and use reference photos for direction.
- Seal with matte varnish: Once the streaks are dry, spray or brush on a matte varnish to protect the weathering and unify the finish. Common mistake: skipping the varnish; the streaks will rub off easily.
