A system for forming a coating on a substrate is provided. The system includes a first mix having a cement, a filler, a defoamer, a cement retarder, a dispersing agent, or any combination thereof. The system additionally includes a second mix having a fatty acid derivative, a synthetic resin, one or more organosilicon compounds, a pigment, a thickener, or any combination thereof. A coating composition is formed by mixing the first and second mix together. Lastly, the system includes a spraying apparatus that applies a wet film to the substrate wherein the cured coating does not yield to wet-rubs and does not stain (effloresce) with cold distilled water.
