When polishing cement-based terrazzo, the biggest challenge is not cutting the surface — it’s controlling the scratch pattern before resin.

Recently, one of our long-term European terrazzo contractors running a Scanmaskin Combiflex (3-head system) asked for a better transition after 60# metal grinding. His goal was clear: polish consistently up to 200 grit without unnecessary resin wear.

This is a common situation in real terrazzo projects.

The Typical Problem in Cement Terrazzo

After 60# metal grinding, contractors often face:

• Visible metal scratch marks

• Uneven aggregate exposure

• Excessive resin consumption

• Inconsistent satin finish at 200 grit

Jumping directly from 60# metal to 100# resin can work — but it is rarely efficient.

⸻

The Recommended Tool Sequence

For cement terrazzo on Scanmaskin Combiflex (standard 3-head / 9-tool setup), we recommend:

Step 1 – 60# Metal (Soft Bond)

Aggressive cutting and aggregate exposure.

Step 2 – 50# Ceramic Hybrid (4 inch)

Removes metal scratches evenly and stabilizes the scratch pattern.

Step 3 – 100# Resin (4 inch)

Refines the surface and begins polishing.

Step 4 – 200# Resin (4 inch)

Delivers consistent satin finish with controlled clarity.

This sequence reduces resin wear, improves polishing consistency, and minimizes rework.

Why 50# Ceramic Hybrid Is Critical

Many contractors underestimate the importance of the hybrid stage.

On cement terrazzo:

• The surface is hard and uneven

• Aggregates create variable resistance

• Metal tools leave aggressive scratch patterns

A ceramic bond hybrid 50# bridges the gap between metal and resin.

It removes metal scratches without creating new deep marks, making the polishing stage smoother and more predictable.

For contractors polishing only up to 200 grit, this transition step significantly improves surface uniformity.

Machine Setup Matters

The Scanmaskin Combiflex uses a 3-head planetary system.

Each head takes 3 tools — meaning a balanced setup requires 9 pieces per grit.

Running fewer tools can cause:

• Uneven grinding pressure

• Tool wear imbalance

• Inconsistent surface pattern

For optimal performance, always use a full 9-piece configuration per grit.

Real-World Result

By switching to:

• 4-inch 50# ceramic hybrid

• 4-inch 100# resin

• 4-inch 200# resin

Contractors reported:

• Faster scratch removal

• Lower resin consumption

• More consistent satin terrazzo finish

• Reduced labor time

⸻

Final Recommendation for Cement Terrazzo Contractors

If you are running:

• Scanmaskin Combiflex

• Cement-based terrazzo

• Polishing up to 200 grit

The 50# ceramic hybrid transition step is not optional — it is efficiency insurance.

Choosing the correct sequence is more important than choosing the cheapest tool.
