Kronalux® Luminous spray 758

What are fluorescent colors used for?

It is not always possible or practical to have sufficient light sources available at all times. In such cases, it is a good idea to use a fluorescent paint to draw attention to specific areas. Obvious examples are building sites and similar temporary or permanent obstacles such as steps or stairs. A luminous paint can therefore be used to mark something that should remain conspicuously visible at dusk or in the dark, even in the event of a power failure. This also includes directional markings, for example of escape routes: If the electrics fail as a result of a fire, directional arrows marked with luminous paint reliably show the safe way out of a building. It also makes sense to use luminous paint to signal the location of fire extinguishers, fire alarms and other emergency equipment in an eye-catching way. Of course, you can also simply mark a light switch with luminous paint so that it can be found immediately even in the dark. Road and sidewalk markings as well as safety-related pictograms are also good examples of the use of luminous paint.

Fluorescent paint for decorative designs

A completely different area of application is perhaps less relevant to safety, but all the more attractive: you can also work creatively and decoratively with fluorescent paint. For example, a radiant starry sky on the bedroom ceiling is guaranteed to make your eyes light up, night after night. You can also paint with fluorescent paints. Simply create a “good ghost” in the children's room that appears in the dark. These are just two ideas for the effective use of fluorescent paints in the home. Even artists appreciate the great effect of luminous pigments, which make their works appear very different at day and night.

What is a fluorescent paint?

There are many different terms for fluorescent paint, but they all basically mean the same thing. They are called afterglow paint or night glow paint because they continue to glow after dark, i.e. at night. In English, they are therefore also known as “glow-in-the-dark paints”. In common parlance, they are also known as phosphorescent paint, neon paint, fluorescent paint, luminescent paint, self-luminous paint or black light paint. However, the latter is rather misleading because no additional light source, such as black light, is required for a fluorescent paint to glow. We explain how a luminous paint works in the following section, in which we also introduce you to our practical Kronalux® luminous spray.

How does Kronalux® luminous spray work?

Our colorless special paint 758 Kronalux® luminous spray contains light-storing pigments that release the stored light again when daylight or artificial light fades, making the color glow in the dark in an unmistakable yellowish-greenish tone. This works reliably without any additional light. As already mentioned, no extra light source or black light is required.

Our Kronalux® illuminating spray is available in a practical 400 ml spray can. This quantity is sufficient for approx. one square meter. It is transparent and it only takes a few sprays to create a striking eye-catcher that is visible at all times. You can find more information on application in the next section.

How is the luminous paint applied?

The application of Kronalux® luminous spray is very simple. As with all paints, the surface should be clean, dry and free of grease and dust. It is important that the surface to be marked is primed white beforehand, as this greatly improves the luminosity to be achieved. Our Multigrundspray 715, for example, is suitable as a primer. Once the primer has dried, we recommend applying three coats of our luminous spray for the optimum luminous effect and then sealing with Kronen® preservative spray to protect against abrasion and weathering. This is particularly useful outdoors!

Higher layer thickness - higher luminosity

Please note: The luminosity of our Kronalux® luminous spray increases with the layer thickness applied. In short: the more luminous paint is applied to the surface, the more intense the luminous effect. The afterglow effect is strongest in the first 90 minutes after nightfall. After that, the areas marked with the phosphorescent afterglow paint are still clearly visible for up to 12 hours.

Coverage

One can (400 ml) of our special paint for photoluminescent safety markings (DIN ISO 16069:2019-04) is sufficient for an area of around 1 m2. The paint is dust-dry after around 10 minutes and touch-dry after 30 minutes. The complete drying time of the luminous paint is 24 hours.

Surface preparation

The surface must be clean, dry and free of dust and grease before the luminous paint is applied. For full luminosity, the substrate must be primed white.

Coating structure

Before applying the fluorescent paint, priming with Multigrundspray 714 white is necessary. After drying, apply 3 coats of Kronalux® fluorescent spray. The thicker the coat, the better the luminosity of the fluorescent paint. To protect the fluorescent paint from abrasion and weathering, apply 1 - 2 x Kronen® Conservation Paint - Spray 609.

Special instructions

Corrosion protection is required for iron in damp or outdoor areas before applying the fluorescent paint to prevent rust formation.

Fluorescent paint is a coating that emits more visible light than is incident from the outside. Fluorescent paints are colored with luminous pigments so that they can emit light when excited by ultraviolet or visible light. This property makes fluorescent paint ideal for safety markings and signage.
