Water-Soluble Patina is a partially water-soluble decorative patina designed to create realistic effects of aging, grime, rust, moisture, soot, wear, and tonal variations on miniatures, models, scenery, props, and other non-porous surfaces. Its formula provides an ultra-matte, natural finish and is designed so that the pigments settle organically into crevices, textures, and reliefs, achieving more believable results than those of conventional paint. Additionally, it is a non-toxic acrylic product with no harsh fumes.

It is important to shake the product well before each use, as some components may separate and settle at the bottom of the container during storage. If it has been left to stand for a long time, you can use metal balls to mix it thoroughly. Using a wet palette is not recommended. It can be applied directly or diluted slightly with water if necessary. Clean brushes and tools with water or alcohol immediately after use and prevent the product from drying on them.

It can also be used with an airbrush to achieve smoother transitions, weathering effects, and large-scale aging effects. Depending on the pressure used in the compressor, it may be necessary to slightly dilute the product for use in the airbrush. In that case, add a few drops of water and stir until well diluted. Clean the airbrush as usual after use.

Apply to clean, dry, grease-free surfaces such as plastic, resin, or metal. Not recommended for porous or absorbent surfaces such as untreated wood or paper. The intensity of the effect will depend on the amount applied, the number of coats, and the technique used. To remove and activate the product, use cotton swabs, a brush, or a sponge dampened with water to remove excess and activate the product, thereby achieving finishes ranging from soft and subtle to more intense, irregular, and personalized effects.

Since it is partially water-soluble, the finish may be altered if it gets wet or is handled with wet hands; therefore, it is recommended to seal the final result with a matte varnish to preserve it and maintain its natural appearance.
