250 ml is about a cup and the contents of the jar, undiluted would have covered a square foot of base if i hadn't gone half snow. it spreads easily with a spatula, can be diluted and takes a full day to dry into a very good semblance of a muddy track. i sealed the remainder tightly and it is still usable a month later

Makes for some great rich mud effect. This is definitely the product to use if you're doing a diorama that needs a nice mud base to work from. It also bonds extremely well with grass tufts and static grass to help add to the detail of your terrain.
