The surface should be evenly matte and cleaned of sanding dust.

How to polish epoxy resin
Polishing does not fix poor sanding. It removes very fine scratches and brings gloss back without overheating the resin.
Epoxy finishing does not start with gloss. It starts with controlling scratches, heat and adhesion for the next layer.
Good finishing is repeatable: grit progression, cleaning, inspection under light and only then polishing or lacquer.
How to choose
Do not start polishing if low-grit scratches are still visible.
Use clean pads and do not mix compounds on one pad.
Work in short passes and check surface temperature by hand.
Compound and pad
Match compound aggressiveness to the last sanding grit. Too gentle a compound will not remove scratches.
After polishing
For heavy-use tables, consider lacquer or coating instead of relying only on polished resin.
How to approach it in practice
Step by step
Identify what you need to remove
Levelling a wave, removing fine scratches and preparing for lacquer are different tasks. Choose the starting grit for the actual defect.
Avoid large grit jumps
Each step must remove marks from the previous one. Moving too quickly to fine paper only smooths deep scratches.
Control heat and dust
Epoxy does not like local overheating. Clean the surface, pads and abrasives often because dust can scratch like extra abrasive.
Match the final step to the goal
For lacquer, adhesion from the TDS matters; for gloss, polishing preparation matters. It is not always the same grit.
Test on a small area
Before the whole worktop, check the effect on a hidden area or sample. It saves time when the system behaves differently than expected.
Common mistakes
Mistake 1
Skipping grits and trying to hide scratches with polishing compound.
Mistake 2
Pressing the machine so hard that epoxy softens from heat.
Mistake 3
Applying lacquer to a surface prepared for gloss rather than adhesion.
Mistake 4
Dirty pads, old abrasives and dust left on the surface.

FAQ
Can every epoxy be polished?
Most fully cured systems can, but soft or under-cured surfaces will smear and heat up.
Why do holograms remain after polishing?
Usually because of an aggressive pad, dirty foam, excessive heat or missing finishing stage.
Does polishing replace lacquer?
No. Polishing gives gloss, but not always the durability required for a worktop.
