The invention discloses crashproof water-resistant stone-like coating and a processing method. The concrete wall surface is coated with the crashproof water-resistant stone-like coating uniformly, the crashproof water-resistant stone-like coating is internally provided with a glass fiber cloth, the four edges of the glass fiber cloth are embedded on the concrete wall, and the crashproof water-resistant stone-like coating is prepared from natural colored sand, acrylic resin, lignocellulose, a defoaming agent, a water repellent, a coalescing agent, an emulsion, a thickening agent, waterproof putty and the balance water. The processing method comprises the steps of concrete wall leveling, glass fiber laying, stone-like coating painting and natural colored sand, acrylic resin, lignocellulose, defoaming agent, water repellent, coalescing agent, emulsion, thickening agent, waterproof putty and water mixing for obtaining the mixed liquid for painting. The stone-like coating is internally provided with the glass fiber cloth, the four edges of the glass fiber cloth are embedded on the concrete wall, and the glass fiber cloth is arranged in the crashproof water-resistant stone-like coating, so that the overall continuity of the coating surface is enhanced, and the surface strength is improved.
