Prep/Master EG Resin Insert

The EG Resin Insert is the resin cushion that velcros onto the EG Metal Adapter and carries your STI Diamond Pad through the resin polishing steps. Its real job: protect your floor. If a diamond pad wears down or gets thrown from the holder mid-run, the resin insert keeps the metal adapter from ever touching the floor — so you don’t scratch the finish you just worked to create.

Why It Matters

It’s common for contractors to skip the resin insert — and it’s a costly mistake. Without it, a worn or thrown pad lets the metal adapter contact the floor and scratch it. The resin insert is cheap insurance against scratching a nearly-finished floor. Use it on every resin diamond step.

Key Details

• 3-inch diameter resin insert
• Velcro attachment — mounts to the EG Metal Adapter
• Protects the floor from the metal adapter if a pad wears or is thrown
• For all resin diamond polishing steps

You’ll Need Both

• EG Metal Adapter — Velcro Attachment — the metal QC adapter this velcros onto
• This EG Resin Insert — the resin cushion that protects your floor

Always run them together on resin steps.

The “EG Resin Insert” and the “EG Metal Adapter – Velcro Attachment” are made to work together.

It is common for contractors to omit the resin insert from the process; however, the purpose of the resin insert is to prevent the metal velcro adapter from contacting the floor and causing scratches if a diamond pad becomes worn down or thrown from the holder.

Therefore, it is vitally important to use both the resin insert and metal adapter together for all resin diamond steps!!

How It Fits

The EG Resin Insert sits between the metal adapter and your diamond pad:

1. EG Metal Adapter — Velcro Attachment (velcro face)
2. EG Resin Insert (this part — velcros on)
3. STI Diamond Pad (your resin polishing pad)
