AK Interactive Terrains - Concrete (250mL) (#AK-8014) is a high-quality, non-toxic acrylic texture paste designed to mimic realistic concrete surfaces for dioramas, scale modelling, and miniature basing. 
It features a spongy, porous texture that dries to a completely matte, light gray finish, perfectly replicating the look of concrete buildings, walls, and airport runways without requiring a base coat of paint.
Entirely non-toxic and safe for indoor crafting.
Works flawlessly in both thin and thick layers. It can be spread easily with a spatula or palette knife.
