Before changing to the next polishing pad, stop and read the floor.
Do not judge only from shine.
A floor can become brighter while the scratch pattern is still wrong. If the next pad starts too early, it will carry the problem forward instead of fixing it.
For final polishing tools, review our Resin Polishing Pads.
Check the scratch direction first
Scratch direction tells you what the previous tool did.
If the lines all run in the same direction as the last grinding pass, the previous step is still visible.
That matters more than surface brightness.
A floor that looks brighter but still shows directional scratches is not ready for the next polishing pad.
Compare the open floor and the edges
The open floor and the edges often tell different stories.
The main grinder gives more stable pressure in the open area.
Edges get smaller tools, hand pressure, angle changes, and less consistent contact.
If the center looks acceptable but the edge still shows deep marks, the sequence is not finished.
Look under side light before changing pads
Look across the slab, not only straight down.
Side light reveals scratch lines, edge marks, and uneven transition areas faster than overhead light.
This check should happen before moving to the next pad.
Once the sequence moves too far forward, the repair usually takes more time.
Do not move forward just because the floor is brighter
Brightness can be misleading.
A pad can make the floor reflect more light while scratches remain under the surface.
That is why the first question is not “Does it shine?”
The better question is “Did the last scratch become small enough for the next step?”
Check for residue before blaming the pad
Old coating, glue, mastic, dust, soft paste, or slurry can confuse the result.
If residue is still on the surface, the pad may load or smear.
If coating residue remains, the job may need removal or grinding before polishing continues.
For removal work, review PCD and Coating Removal.
When to step back to hybrid pads
Step back when metal scratches are still visible.
Step back when the first resin pad makes the floor brighter but not cleaner.
Step back when edges still show deeper marks than the main floor.
A hybrid pad can reduce metal scratch carry-over before resin polishing continues.
For the transition step, review Hybrid Pads.
When the next pad makes sense
Move forward only when the scratch pattern is even enough for the next pad to refine.
The floor does not need to be perfect at every step.
But each step must remove or refine the marks it is responsible for.
If the same scratch remains after the step that should have removed it, the sequence is ahead of the floor.
