Refinishing marble countertop

[allaboutcontrast]

Hi everyone

I was wanting to find someone to sand and polish my marble countertop, as it is old and has a lot of etching. I can't.

So, I am about to try this myself. If I fail, I have to get a new countertop, but if I don't try, I have to get a new countertop. Well, will really want to. So either way...

I have this:

I have watched a number of youtube videos, and I get how to do this. Start with lower grit, working my way up to finer grit. Light pressure, circular motion, not staying in one area too long.

Here's what none of the videos said, believe i or not. Wet sand or dry? The sanding in the videos appears to be dry, but I think it should be a wet sand, no? Thank you!

Just use wet sanding since that is what is recommended. This helps reduce the dust and achieve a smoother finish.
I do not recommend dry sanding as this is for polishing the stone for a cleaner and glossy look.

the comment above is right. and as you sand, a slurry will form. every few minutes, wipe it away with a clean microfiber cloth to inspect your progress. you need to see if the etching is actually gone before moving to the next grit

Wet sand... Always wet sand.
