Diamax 4″ Plastic Red Backer Pad

The Diamax 4″ Plastic Red Backer Pad is a professional-grade support accessory designed to provide a secure, stable platform for Velcro-backed polishing and grinding pads on natural and engineered stone surfaces such as granite, marble, quartz, and engineered stone. Its durable plastic construction ensures consistent contact and pressure distribution, allowing polishing and grinding pads to perform optimally and deliver smooth, even, professional-grade finishes.

Engineered for precision and reliability, this backer pad is particularly effective for flat surfaces, edges, corners, and small-radius areas where control and stability are essential. The 4″ diameter provides the ideal balance between maneuverability and support, making it suitable for detailed work while maintaining enough surface area to support effective polishing and grinding.

Equipped with a standard 5/8″‑11 threaded arbor, the red backer pad is compatible with most angle grinders, air polishers, and water-fed polishing machines, offering flexibility across various fabrication, installation, and restoration applications. Its Velcro (hook-and-loop) backing allows for quick, secure, and tool-free pad changes, improving workflow efficiency and reducing downtime in professional settings.

This backer pad is designed for both wet and dry polishing applications, making it versatile for different stone types and jobsite conditions. Wet polishing helps reduce dust, cool the pad, and extend the life of attached polishing discs, while dry polishing provides portability and convenience for on-site adjustments or smaller finishing tasks.
