How can I make the polished side of marble not slippery? I don't want to use chemicals to do this because these pieces of marble will be used as stepping stones in gardens.
WHAT I'VE ALREADY TRIED: I used an orbital sander with 60 grit sandpaper on one today, but it didn't help too much. However, the paper has already been used so I'll get more tomorrow for the belt sander and start with 40 if the hardware store has it in stock. I'm not sure if this will work, so I'd like to know if any of you know if this is a waste of time. I'd prefer this method or an alternative if it is just as easy because the marble is gorgeous, and I'd love to keep at least some of the color and patterns.
If my first idea is a waste of time, then here's my next thought. If you flip the pieces over, the back of them would be perfectly fine to use, but there's two issues. 1. You cannot really see how beautiful they are, and 2. Some of them have netting on the back that is held in place by crazy strong adhesive, which doesn't sand away easily.
I don't know what to do for issue number two unless you have a suggestion. In regard to the first one, I thought maybe using the reverse process of what I want to do to the polished side on the back side. I want to use sandpaper to begin the polishing process to bring out some of the stones' colorings but stop before the surface becomes slick. This involves starting with a low grit sandpaper and working up to a fine grit. This would be a good idea, but it will take more time - a lot more time considering how much needs to be done.
Do you know if these ideas will work, and if you don't think so, then do you have suggestions that don't involve chemicals or applying gripping tape to the marble (which would hide the pretty)?
