Undercoat is a word used to describe a layer of paint or a substance that is applied to a surface before the final layer of paint or substance is applied. It helps provide a smooth and even surface for the final layer to adhere to. For example, when painting a wall, you would apply an undercoat first to help the paint stick better and look nicer. It can also refer to the layer of fur or hair underneath the outer layer on an animal.
