A method of making a multi-layer coating on a substrate is provided and involves applying a mirror coating to a substrate then spraying a silicate topcoat onto the mirror coating. Applying the mirror coating can involve applying a reflective material to the substrate to form a reflective layer and applying an oxide layer to the reflective layer to form the mirror coating. The oxide layer can be made of one or more oxide layers, and each of the one or more oxide layers can include aluminum oxide, silicon oxide, or a combination thereof. The multi-layer coating provides increased IR emittance and decreased solar absorptance relative to conventional thermal control coatings.
