Reflective Glass Beads (1 LB Bag) for Road Marking — Marktiva
Marktiva’s Reflective Glass Beads are uniform in size and clarity, with a round shape and airport-level quality. These beads are larger than standard glass beads, providing maximum retroreflectivity and strong performance in wet conditions. They have a refractive index of 1.5+ and are designed to boost nighttime visibility by reflecting light from headlights or other light sources. Applying these beads on top of paint or epoxy can extend the life of markings and enhance durability in harsh environments.
Liquitex Professional Effects Medium, Glass Beads — 237 ml
Liquitex Effects Medium combines a transparent polymer gel with regular-sized glass beads to create dramatic reflective effects. It works well mixed with transparent or translucent colors or applied directly over dried paint. This medium serves as a versatile surface for painting over with color, enabling artists to introduce shimmering, textured accents that catch light from different angles.
Reflective Glass Powder (25 LB Bag) Type 1 Highway Beads — Marktiva
Marktiva’s Reflective Glass Powder is made of tiny glass beads designed for road and curb markings, parking lots, and airport surfaces. It can be applied to water-based paints, oil-based paints, alkyd coatings, epoxies, and other coatings to create reflective markings. The powder form enables bulk application for large-scale projects, with benefits in visibility and safety across traffic and pedestrian areas.
Liquitex Effects Glass Beads Medium, 8 oz Jar
This Liquitex medium is designed to provide a textured glaze with embedded glass beads. The 8 oz jar offers a practical amount for mixed-media art, murals, or craft projects requiring visible sparkle and reflective detail. The product emphasis is on enabling artists to add glass bead texture to their work while preserving paint adhesion and flexibility.
Amy Howard Atelier Glass Beads Gel Medium — 8 oz
Amy Howard’s Atelier Glass Beads is a decorative, water-based acrylic gel medium that dries clear and contains a high concentration of XL size glass beads. It’s designed for furniture, stencils, and decorative projects, producing a textured, bead-filled surface. The medium can be tinted with mica powders or pigments to customize color while maintaining the bead texture’s visibility and depth.
Buying Guide: Key Considerations For Glass Bead Additives
- Application environment: For outdoor or traffic-related projects, choose products with high retroreflectivity and UV/weather resistance, such as airport-grade or high-visibility beads.
- Bead size and density: Larger beads offer more pronounced texture and light reflection, while finer powders create subtle, even coverage for art or signage.
- Compatibility: Ensure the additive works with your base paint or coating (water-based, oil-based, epoxy, or alkyd). Some products are designed specifically for acrylics or gels.
- Finish and appearance: Decide between clear gels, tinted mediums, or powder formulations based on your desired final look—glossy, matte, or pearlescent.
- Durability and safety: For road paints or signage, prioritize durable, weather-resistant formulations and check for any safety data related to dust or fumes during application.
- Application method: Some products require mixing with paints, while others are applied as topcoats or through pouring methods. Follow manufacturer guidelines to ensure proper adhesion and curing.
- Ease of cleanup: Water-based options tend to be easier to clean while minimizing solvent exposure; consider workspace ventilation and protective equipment.
Across projects, these glass bead additives provide a spectrum of options—from industrial-grade reflective beads for safety-critical surfaces to artistic gels that add tactile texture and light-catching shimmer. Selecting the right additive depends on the substrate, desired visual effect, and environmental conditions.
