Abstract
A method of applying a protective coating to a concrete or concrete-related substrate. The substrate is heated, and then electrostatically-charged coating powder is deposited onto the substrate with the coating powder coalescing into a coherent layer. Then the substrate and the coating are cooled to form the protective layer. The moisture content of the concrete or concrete-related material is sufficiently low so that bubbles or separation does not occur, and sufficiently high so that the electrostatically-charged particles will adhere to the substrate.
