how to polish marble edges?

[flapjack]

yes its me again with another question..

i have some polished white marble and want to polish some of the exposed edges around the tub etc.

I have read posts in here that mention PVA disk, sand paper etc etc. but im not really clear on which one would make the most sense for me..

I have a 4" angle grinder.. i have an orbital sander.. so do i/can i just buy variable grit sandpaper for the orbital sander or is that a waste.. do i buy some sort of grinding disks for the grinder..

can someone walk me thru the method of using either one .. all the steps etc.. are the paper/disks I need available at any big box stores?

Much appreciated.

you san use either mthod marble is soft and cand be done dry if you dont have very many. you need different grits to polish stone, higher the number more polish you will get

so what kinda of either orbital sandpaper or grinding disk do i need.. does it matter? or do i need to special order something? and where from?

Thanks

if you can get the pva disks if not use regular sand paper look in a tile and stone store they wil have everything you need

I like the PVA Disks. I just bought a multi pack, 2 of each grit, so 10 disks for $38 at Arizona Tile. Dal-tile is another resource for them.

Rob,

I'm sanding 3/4 inch marble with an orbital sander and hook/loop sanding disks made by Norton sold @ homedepot. The edges won't be mirror polished but have a matte finish which is good enough. I use 150 grit then 220.

cool thanks for the help..

i might actually chicken out and sort of frame the marble in some wood trim.. so i dont have to try to make many of the edges look good :-)

When you polish something like granite, you continue to use finer and finer grits up to about 3000 or even higher. If you did the same thing on marble, it would approach the same shine as a polished top surface...don't skip grits in between, as each grit leave scratches, and when you skip grits, it takes much longer to polish out the previous scratches (while leaving your new ones). Keep geting finer, and stop when you are happy with the result.
