This paint is a high-grade acrylic spray paint that contains luminescent pigments that absorb and store light particles, then emit glowing-light in darkness. The intensity and length of the glow period depends on the thickness of paint layer applied. It is recommended to apply multiple layers over a well-primed white surface. The glowing effect will be strongest immediately after charging the painted surface with a strong light source and then exposing the painting to complete darkness.Details:Luminescent orange400 mLGlow in the dark acrylic paintLimited resistance to weathering, light and UV influencesSuitable for multiple surfacesFor indoor and outdoor applicationsMay need longer drying time depending on substrateWARNING: Extremely flammable liquid and vapor.
