Resist Aggregate (Armorstone)

RESIST Aggregate – Armorstone

RESIST Wear Surface Aggregate – Armorstone is a premium crushed basalt aggregate specifically selected for use within the RESIST Sand Finish Overlay System. When broadcast into freshly applied RESIST Epoxy, Armorstone creates a durable, skid-resistant wear layer that delivers superior performance in high-traffic and demanding exterior environments.

Approved by the Federal Highway Administration and specified by more than 40 Departments of Transportation, Armorstone is recognized for its exceptional durability, wear resistance, and long-term performance. Its angular particle structure creates enhanced traction while providing a professional, decorative finish that complements both commercial and industrial concrete surfaces.

As a key component of the RESIST System, Armorstone works in conjunction with RESIST Epoxy and RESIST Top Coat to produce a complete overlay solution that offers superior bond strength, impact resistance, waterproofing, and long-term protection compared to traditional concrete overlays. The aggregate broadcast helps create the textured wear surface that improves safety while contributing to the system’s proven durability in extreme conditions.

System Benefits

When used as part of the complete RESIST Sand Finish Overlay System, Armorstone contributes to:

• Enhanced skid resistance
• Improved impact and wear resistance
• Long-lasting surface protection
• Superior durability in extreme weather conditions
• Waterproof and chemical-resistant performance
• Extended service life for concrete substrates

Application Overview

After RESIST Epoxy has been applied to the prepared surface, Armorstone aggregate is broadcast into the wet epoxy at a rate sufficient to completely cover the coating. The aggregate becomes mechanically bonded within the epoxy matrix, creating a textured, slip-resistant wear surface. Once cured and excess aggregate is removed, RESIST Top Coat is applied to lock in and protect the finished system.

Contractor Pro Tips

• Broadcast aggregate immediately after epoxy placement.
• Apply enough material to achieve complete epoxy coverage.
• Ensure consistent distribution for uniform texture and appearance.
• Remove excess loose aggregate before applying the top coat.
• Follow all RESIST System installation procedures for optimal performance.
