Madame K has started a little furniture renovation project on a cabinet with a black marble top. She has given me the job of polishing up the marble
It has some fine etched rings from what is probably plant pots, plus a few small mild scratches. It's a bit hazy too
I've done a dry cloth and bicarbonate of soda clean and polish and it looks hopeful, but I think I might need to use something more
I've seen some marble polishing kits, basically very fine diamond grit pads to work through attached to a grinder but was wondering if they are any good or is there any thing else to consider doing?
It's a small top, half metre sq at most. I'm not after perfect, just tidy and ideally the etching gone or reduced
Oxalic acid?
It really hard to remove etched ring marks as you need to take off a lot of material - so unless you do the hole top you risk ending up with a surface that’s no longer flat.
we tend to take some of the roughness out with a polishing compound (t cut or autosol) and then try to disguise the damage with some colour and then wax/sealer/laquer.
I guess you'd need to grind the top flat first, as if you use something that's not abraisive enough to grind the ridges flat, you'll just be polishing the ridges...
And as you said, then polish it up with successivley finer grits until its shiney enough for you... shouldn't be too hard if its only half a square meter? No other way to do it really...
If the 'etching' is very shallow then you might not need a 'disk too rough' to start with...the finer you can get away with in the begining to remove the etching, the less polishing work with the finer grits you'll need to do to bring it back up to a shiney finish.
