Chipping will occur, particularly in the igneous stone varieties, as a result of sawing operations. The exiting portion of the diamond blade used to cut granite may create some small chips. A small chamfer, called an „arris‟, of approximately 1/16”x1/16” can be used to eliminate most of these chips. The use of an arris will make the seam appear wider than its actual dimension when filled. Larger chips may be repaired with epoxy or polyester resin if the completed repair is consistent in color and texture with other general areas of the slab. AMF, Inc. does not normally use arrises when installing granite countertops as it makes the seams appear much wider. However some stones are naturally more brittle and susceptible to more chipping. These stones will be arrised at AMF’s discretion in order to create the most aesthetically pleasing installation. All seams are machined in our shop and when assembled in the field any visible chips are filled with polyester resin.
