I am impressed with this product. I have been using it to provide texture when basing my miniatures. The product can be used as is straight out of the jar or can be thinned by two methods: water or acrylic thinner. I found when applied in a thin layer it dries within a hour, keep in mind the drying time will depend on the layer thickness. Even when thinned, the product maintains its texture to look like dirt when dried. The product works well with other terrain products such as static grass. Those concerned about oder, I found the product has a light smell of dirt which disappears as the product dries.
