The invention discloses an LED lampshade coating. The coating is composed of a resin, silica, titanium dioxide, aluminium oxide, fluorescent powder, calcium carbonate, barium sulfate, and ethylene bis stearamide, and comprises, by mass part, 200-500 of the resin, 5-30 of silica, 3-50 of titanium dioxide, 2-20 of aluminium oxide, 100-450 of fluorescent powder, 3-25 of calcium carbonate, 8-40 of barium sulfate, and 10-80 ethylene bis stearamide, wherein each component is powder more than 300 mesh. The invention also discloses a coating method of the LED lampshade coating. According to the invention, after an LED lamp is coated, light emitted from the lampshade has advantages of uniform light scattering, a large emitting angle, and high transmittance.
