How to treat granite to use for stepping stones?

I have several slabs of granite that are too slick to use for stepping stones. Could I coat them with popolyurethane and dust them with sand. Any ideas would be appreciated.

    Is the under side of the granite also slick? I saw someone make a path of granite slabs and they just used them upside down since the bottoms of the slabs weren't finished.

    There is an Anti-Slip tile cleaner. It is suppose to roughen up the tile.

    Thanks. I need something to make the granite slip proof. Interesting video. I have a lot of pavers and this had some good info. Thanks again.

    To strip and roughen the surface. Marble, granite, and stone do NOT like having acidic (ie: citrus-based) cleaners used on them. Citrus or vinegar will actually cause “etching” on granite countertops. Granite countertops also don’t like it when you use something like Windex on them because it strips the “seal” off of the stone. Spray CLR, vinegar, Windex, or any citrus based cleaner. Some will roughen more than others. Experiment with a few. Rinse well. Then just seal them to slow down any more deterioration.
