Quick Answer

Polish stair treads with small 3–5 inch pads on a variable-speed grinder, working the same grit sequence as the landing, and stopping at a honed (400–800) finish on the walking surface. Grind the nosing with coarse metal, then step through resin to blend with the landing.

Key Features of Stair Polishing

• Slip safety: treads should be honed (400–800), not mirror-polished.
• Nosing: the rounded edge needs coarse metal and careful grinding.
• Small tools: hand grinders fit tread depth and riser faces.
• Blend: match the landing's final grit for a continuous look.

How to Choose the Finish by Location

Location	Finish	Grit
Tread surface	Honed, slip-resistant	400–800
Nosing / edge	Rounded, honed	100–400
Landing (if glossy)	Match landing	Up to 1500+

How to Use It

• Grind the nosing edge smooth with coarse metal, working evenly around the radius.
• Step through fenix polishing pads or standard resin pads from 100 to 800 on the tread.
• Keep the tread at a honed finish for grip; polish the nosing slightly more for detail.
• Vacuum risers and clean each tread before moving to the next.

Frequently Asked Questions

Q: Can I polish stairs with a floor machine?

A: No — use a hand-held variable-speed grinder with small pads for treads and risers.

Q: Why stop at 800 on treads?

A: Honed treads resist slips and look consistent with most commercial stair specs. High gloss on steps is a hazard.

Q: How do I match treads to a glossy landing?

A: Polish treads to 800, then blend the nosing and first few inches of the tread with the landing's higher grits.

Conclusion

Stairs need grip and matching looks. Grind the nosing, step through resin to a honed tread finish, and blend into the landing. Use fenix polishing pads on a small grinder for clean, even treads.
