Paint Medium VALLEJO Ammo Terraform Premium Textures – River Sand (texture medium for modeling)

VALLEJO Ammo Terraform Premium Textures – River Sand is a ready-to-use texture medium designed for scale modeling and diorama groundwork. Formulated to reproduce the look and feel of river sand, this medium delivers a fine granular surface that blends with terrain features such as banks, riverbeds and shorelines. It is supplied in a paste-like consistency that can be applied directly from the container, and once dry it accepts washes and paints to achieve wet, dry or mixed sand effects.

Advantages

This texture medium provides an authentic granular texture without the need to mix in real sand or additives. Its consistent formulation ensures even application and predictable drying, while remaining workable long enough to shape and blend with other scenic materials. The product is compatible with standard hobby paints and weathering products, and it can be thinned or sculpted mechanically to create gradients, slopes and embedded details.

Suitable for

• Groundwork on dioramas representing rivers, streams and shorelines
• Base detailing for scale models that require realistic beach or riverbank surfaces
• Scenic texture for wargaming boards, display bases and terrain pieces

Key specifications

• Ready-to-use texture medium with fine granular composition
• Paste-like consistency suitable for brushing or applying with a spatula
• Dries to a matt, paintable surface compatible with acrylic paints and washes
• Adheres to typical modeling substrates such as plastic, resin, wood and foam

How to use

Apply the River Sand texture medium directly from the container using a brush, palette knife or spatula to the prepared surface. Spread and shape the material to form banks, channels or flat areas; work while the medium is still wet to blend edges or embed small details. Allow the texture to dry fully before applying paints or washes—drying time depends on layer thickness and ambient conditions. Once cured, paint and weather the surface to achieve desired wet or dry sand effects.

Usage recommendations

For best results, prepare the base with a primer or PVA glue to improve adhesion on non-porous surfaces. Apply in thin layers for faster drying and to build up depth gradually. Test paint compatibility on a small area before full application. Clean tools with water before the medium dries.
