Cutting, Polishing & Finishing for Metalwork

A better metal finish starts with choosing the right compound for the surface in front of you.

A freshly fabricated component may need cutting to reduce visible marks before polishing. Another workpiece might already be smooth & only require a brighter final finish. The compound you choose should reflect the starting surface, metal type & desired result.

Union Buffing Compounds at Industrial Shed include five polishing products for different metal finishing stages: Fastcut Grey, Tripoli Brown, SS-White, SSX Green & Multishine Blue.

The range covers initial cutting, surface refinement, stainless steel polishing & bright finishing applications. Each compound has a distinct role, so choosing by colour alone is not enough.

For fabrication workshops, metalworking businesses & maintenance teams, matching the compound to the polishing stage can help produce more consistent results while avoiding unnecessary passes.

Browse Union Buffing Compounds below to compare the five formulas & select a suitable option for your next metal finishing task.

What Are Union Buffing Compounds?

Union Buffing Compounds are polishing products used with suitable buffing wheels & powered polishing equipment to refine the surface of compatible metal workpieces.

Different compounds are intended for different stages of the polishing process.

► Cutting compounds: Used where the surface needs more substantial refinement
► Refining compounds: Help improve the surface after earlier preparation
► Finishing compounds: Used to improve the final appearance of a suitably prepared workpiece

The Industrial Shed collection contains five Union compounds covering these applications.

The correct choice depends on the workpiece material, existing surface condition, polishing wheel & desired finish.

Compound colour is a product identifier, not a universal polishing grade.

Why Choose Union Buffing Compounds?

Union's five-compound range provides different options for workshop polishing requirements.

Stage-specific selection: Choose a compound for cutting, refining or finishing rather than expecting one product to perform every task.

Stainless steel option: SS-White is listed specifically for stainless steel polishing & finishing.

Different finishing goals: The range includes products intended for initial cutting through to brighter final surface presentation.

Repeatable workshop processes: Recording the compound & wheel combination can help maintain consistency across similar components.

Clear product identification: Five named compounds make it easier to compare options & reorder the required product.

Common Applications for Union Buffing Compounds

Fabrication & Metal Finishing

Fabricated metal components may require polishing after grinding, cleaning or other surface preparation.

The compound should be selected according to the metal, existing marks & required appearance.

For suitable localised cleaning before finishing, compare Union | End Brushes.

Stainless Steel Polishing

Stainless steel components may require additional refinement to improve their surface appearance.

SS-White is the collection's specifically identified stainless steel polishing compound.

Use compatible equipment & avoid contamination from carbon-steel work where it matters.

Machinery Maintenance & Restoration

Some suitable metal parts may benefit from polishing after cleaning & inspection.

Check whether polishing could affect protective coatings, dimensions or functional surfaces.

Where grease or residue is present, browse Cleaning Chemicals & Solutions.

Repeat Workshop Production

When multiple components need a consistent finish, document the compound, buffing wheel & polishing sequence.

Union Buffing Compound Product Selection Guide

Compare the Five Compounds

Fastcut Grey – Initial Cutting

Fastcut Grey is intended for earlier-stage polishing where suitable surface marks need to be reduced before finer finishing.

It may be appropriate when a workpiece requires more substantial refinement.

Deep scratches may still require separate abrasive preparation.

Tripoli Brown – Surface Refinement

Tripoli Brown is used for cutting & polishing suitable metal surfaces.

It may help refine a prepared workpiece before moving to a finer finishing stage.

SS-White – Stainless Steel Polishing

SS-White is listed for stainless steel polishing & finishing.

It is a relevant option for suitable stainless steel workpieces that have already received the necessary preparation.

SSX Green – Fine Polishing

SSX Green is intended for finer polishing & improved surface presentation.

It may suit a later polishing stage where the metal is already appropriately prepared.

Multishine Blue – Bright Finishing

Multishine Blue is intended for applications requiring a bright, refined finish.

It is a finishing option rather than a substitute for earlier cutting or surface preparation.

How to Select the Correct Compound?

Step 1 – Identify the metal. Confirm that the compound is suitable for the workpiece material.

Step 2 – Inspect the starting surface. Determine whether the job requires cutting, refinement or final polishing.

Step 3 – Choose the polishing stage. Select the compound according to the finish required.

Step 4 – Match the buffing wheel. Use a compatible wheel & follow the equipment manufacturer's instructions.

Step 5 – Test the result. Check a suitable test area before polishing the entire workpiece.

Expert Tips for Using Union Buffing Compounds

Don't Expect a Finishing Compound to Remove Deep Scratches

If visible scratches remain after polishing, the surface may require earlier preparation or a more suitable cutting stage.

Keep Buffing Wheels Separate

Using dedicated wheels for different compounds or workpiece materials can help reduce unwanted mixing & contamination.

This is particularly important when polishing stainless steel.

Avoid Excessive Pressure

Buffing generates friction & heat.

Heavy pressure or prolonged contact may damage sensitive surfaces without improving the result.

Clean Between Polishing Stages

Remove residual compound before moving to a finer polishing stage where appropriate.

Use a cleaning method compatible with the metal.

Inspect Under Suitable Lighting

Check the finish from different angles to identify remaining marks or uneven areas.

For workshop inspection & setup, explore Site Lighting & Electrical Supplies.

Follow Safe Buffing Practices

Before use:

► Inspect the polishing wheel
► Confirm machine & wheel speed compatibility
► Secure the workpiece appropriately
► Use required guarding
► Wear suitable eye & face protection
► Keep loose clothing & hair clear of rotating equipment
► Assess ventilation & dust-control requirements
► Follow the compound's safety information
