Product Overview
Darknite Glow Oil-Based Glow in the Dark Paint is a premium photoluminescent coating formulated with high-performance strontium aluminate pigments. Designed for decorative, safety and industrial applications, the paint absorbs ambient light and emits a bright green or aqua blue glow in darkness for many hours after charging.
The durable alkyd resin formulation provides excellent adhesion to properly prepared surfaces and is suitable for both interior and selected exterior applications when protected with a suitable UV-resistant clear coat.

Surface Preparation
Proper surface preparation is essential for maximum adhesion and glow performance.
Concrete
- Remove dust and loose particles.
- Allow new concrete to cure completely.
- Repair cracks and defects.
- Prime using a white oil-based primer.
Wood
- Sand smooth.
- Remove dust.
- Prime with a white oil-based primer.
Metal
- Remove rust, oil and grease.
- Apply a suitable anti-corrosion primer followed by a white undercoat if required.
Previously Painted Surfaces
- Remove loose or peeling paint.
- Sand glossy finishes.
- Ensure compatibility with the existing coating.
Primer Recommendation
Maximum glow performance is achieved over a clean white reflective primer.
| Surface | Recommended Primer |
|---|---|
| Concrete | White Oil-Based Primer |
| Timber | White Oil-Based Primer |
| Metal | White Anti-Corrosion Primer |
| Existing Paint | White Compatible Undercoat |
A white primer reflects more light back through the glow layer, significantly increasing brightness and glow duration.
Application Instructions
- Stir thoroughly before use.
- Apply only to clean, dry surfaces.
- Apply evenly using brush, roller or spray equipment.
- Avoid application during rain or excessive humidity.
- Do not apply below 10°C.
- Ensure adequate ventilation.
Application Methods
