Questions and Answers for Archer USA 4 in. #1500 Grit Wet Diamond Polishing Pad for Stone

A:  Grinding and polishing a soft stone surface like petrified wood is a multistep process. These pads are typically used for polishing the edges of stone countertops after they have been cut and profiled. It takes practice to build up proficiency using a series of these pads to consistently achieve a high-polish shine. For a good-sized surface area of petrified wood, you'd probably have the best luck using the full range of pads (50,100, 200, 400,800,1500,3000 grit), plus a product called "densifier" that is typically used to polish industrial concrete floors, plus a lot of patience. You would need to mount each of these pads on a rubber backer mounted in turn on a rotary polisher equipped with a separate or integrated GFCI device and either a separate or integrated water feed. The most expensive version of this, a fully integrated solution with digital speed control, is a Makita stone polisher. There are other, less-expensive ways. What you would do is polish the piece with each of the pads in turn until you get to 400, apply denisifer, and polish all the way to 3000. You should get a nice shine going on your petrified wood that way. I would advise you to practice the full procedure on scrap rocks before you try this on your favorite piece of stone.
