Whether its a Corian, Granite or Quartz countertop like Silestone- they provide a quick and easy way to bond a mechanical fasteneing device to the underside of the countertop.
There are many ways to accomplish the bond using different types of glue but as a general rule, the application and preperation process are importantl keys to success whichever adhesive you choose.
I would reccomend a toughened acrylic or a fast curing epoxy that will provide impact resistance if you happen to bump the post after it is bonded to the surface. Many fabricators simply use the seaming adhesive itself and this is a great option as well.
When bonding to Natural stones like granite, be sure to remove the contamination left from the quarrying process on the back of the slab. This is best done by grinding down to the meat of the stone and then cleaning away all the dust and slurry that can be imbedded in the rough underside of the slab. If you fail to do this, any bond you do create will be extremly suseptible to failure. Even on Solid Surfaces like Corian, removing contaminants and increasing the surface area by way of abrasion (sanding) will greatly improve the ultimate bond strength. These general guidelines and can be applied in many situations if you want to increase the overall strrength of almost any bond.
