Quick Answer

A polished finish is built step by step, and every grit stage has a job to do. For soapstone and slate, use 400-1200 grit stage resin pads dry at low speed, then finish with mineral oil or countertop wax. These soft stones don't require high mirror finish — the oiled look comes from an open, lightly honed surface, not from 3000-grit stage burnishing.

How Soapstone and Slate Behave

What matters most in this stage.

High-gloss burnishing fights the stone's nature — what buyers want is a even, sealed, slightly honed face.

Miss this step and the gloss will not come up evenly.

Pad Selection

The practical details.

Stop at 1200 — finer pads close the pores and reduce how well oil penetrates.

Crews that rush this part rarely get a mirror finish.

About Workflow

Key points for the polishing sequence.

Pair with 3-inch resin pads on a variable-speed polisher for counters.

• Buff with a soft cloth; re-oil every 1-3 months.
• Stage to 800, after that 1200, keeping the surface level.
• Wipe clean and let fully dry.
• Wet-sand or dry-burnish scratch marks out with 200-400 resin pads at low rotations per minute.
• Apply mineral oil or wax in the grain direction; let it soak 15 minutes.

This stage decides how much reflection the floor finally shows.

What Not to Use

What matters most in this stage.

• Stop acid cleaners — soapstone tolerates them, slate does not.
• Stop high-speed burnishing — it heats and stresses the stone.
• Stop coarse metal-bond pads — they cut too deep on soft stone.

Miss this step and the gloss will not come up evenly.

Care Tips

The practical details.

• Re-oil soapstone regularly to keep the dark, even look.
• Clean with mild soap and water; never abrasive powders.
• Seal slate with a stone sealing layer before oiling to reduce staining.

Crews that rush this part rarely get a mirror finish.

Frequently Asked Questions

A: For most jobs, A 800-1200 honed finish; the oil does the rest. Too fine a burnish blocks the oil.

Q: Am I able to use the same pads for soapstone and granite?

A: In short, Yes, resin pads work on both, but soapstone requires finer grit stages and lower speed — never use granite's aggressive start on soapstone.

Q: How often should I oil a soapstone countertop?

A: The practical answer is, Every 1-3 months, or when a water drop stops beading.

Q: Does polishing remove soapstone scratches?

A: For most jobs, Yes — 200-400 resin pads erase light scratch marks, then 800-1200 restores the honed face.
