You need to polish then if the cuts are fairly smooth.
Try our dry resin bond diamond polishing pad set. You can find it at
www.defusco.com under diamond products>polishing pads and backers. You will also need a rigid backing pad and a variable speed grinder as these pads work up to 4,500 RPM.
You might want to get our DVD "Fabricating Stone for the Do-It-Yourselfer". It discusses how to do an edge design and how to polish it properly. If you have any questons call our office Monday - Friday at 800-289-6834.
