My father worked in the construction business, so I asked the employees.
What I asked:
1. Is it possible to remove it by polishing?
2. Is it cheap to replace (is it possible to replace it)?
3. Is it only about eliminating the use of chemicals?
I ask these three questions
Divide the majorly damaged area into three parts.
1, sidewalk block
2, asphalt
3, Marble (exterior material)
But

sidewalk block
replaceable
Polishable
You can just turn it over and use it.

asphalt
There are so many different types that you have to see the site.
If a heating wire is installed
Cannot be polished, must be reapplied
If there is no heating wire, it may be possible to reapply asphalt concrete.

Hwan’s Proposal
marble
Polishing is not possible: Marble deteriorates and changes color over time after construction, but if polished, the color of the existing marble and the polished marble will be different.
Impossibility of re-construction: In the case of marble, if the stone is not the same, the color or pattern will be different and it will become mottled.
Removal using chemicals: It is possible to remove the surface color, but isn’t it difficult to completely remove it because it is a stone and has the property of absorbing? It is said
PS: I’m angry at some idiot for putting lacquer on a stone.
