Fluorescent Spray Paint
Fluorescent spray paint exists to make the thing that must be seen visible. What separates it from ordinary paint is that it absorbs part of the light falling on it and returns it at a shorter wavelength: brightness rises by up to 400% and the surface glows under ultraviolet light. This page lists six fluorescent colours in 400 ml cans.

Why a white ground makes the difference
Fluorescent pigment does not hide; it lets some of the colour underneath through. Sprayed on a dark ground it has no light to send back and the colour reads dull.
A white ground sends the light back through the pigment a second time. That is why the manufacturer specifies white for the best result: on dark surfaces, lay white primer or white paint first, then the fluorescent coat.
Where it is used
On site: excavation lines, pipe routes and level marks. In the warehouse: walkways and rack numbers. In the plant: emergency equipment and warning lines.
On the display side: stage, window and event work, where glowing under black light is the whole reason for choosing the product.
Frequently Asked Questions
Does fluorescent paint glow in the dark?
Not on its own. Fluorescent pigment returns ultraviolet or visible light the instant it falls on it; when the light stops, so does the glow. Paint that glows by itself in the dark is phosphorescent (neon/glow type) and is a different product.
How long does it last outdoors?
Fluorescent pigments fade under UV over time; that is the chemistry of the paint, not a mark of quality. For permanent outdoor marking, overcoat it with clear varnish or renew it on a schedule.
Which colours are available?
Six: red, yellow, orange, green, blue and pink, all in 400 ml cans.
Is it suitable for floor marking?
For visibility, yes, but aerosol paint wears under foot and vehicle traffic. Use floor paint for a permanent line; fluorescent aerosol is the right product for temporary marking, levels and routes.
