There is nothing worse than drying and examining an edge that you think is "done," only to reveal that there are still scratches deep in the stone. By using a pad that is designed to abrade the scratches left from a saw blade or router bit, the fabricator can eliminate this problem in one or two steps. Honing pads (electroplated or vitrified pads) are made specifically for this purpose. By having all of the diamonds exposed on their surface, these pads can quickly sand any deep scratches remaining from the cutting or shaping process. Honing pads come in a couple of different styles, depending on the manufacturer, but the purpose they serve is the same - scratch removal and conditioning of the edge before the polishing process begins. By comparison, a resin polishing pad is just that, with diamonds suspended in a plastic matrix, which gives the resin pad less aggressive capabilities. While it is true that you can hone with a coarse grit resin pad, they are not really made for this task and will wear out quickly under these circumstances.
Many fabricators make the mistake of going right to a 50-grit resin pad on a piece of stone that just came from the saw or router, and cannot understand why this 50-grit pad wears out quickly and doesn't remove all of the scratches. This is simply a matter of not using the correct pad for the task at hand. The scratch patterns that can be achieved from a 50-grit honing pad are much more aggressive than those from a 50-grit resin pad, which allows the honing pad to remove deep scratches faster and more efficiently. A simple way to illustrate this is to take a honing and resin pad of the same grit, run them side by side for the same amount of time on an edge and observe the results.
For this issue of Stone World magazine we talk to Polycor about the use of Limestone in the Louis Vuitton Foundation building. Also with limestone we spoke to Buechel Stone about the Pray Stone limestone quarry. We also put together a product roundup of some of the CNC tools and accessories available today.
For this issue of Contemporary Stone & Tile Design we focus on the current quartz trends and the use of quartz in a modern farmhouse. Also, learn about how natural stone is used to blend nature and exterior architecture!
