This is a 6oz aerosol can of NCF Stone glue accelerator for natural stone.
NCF Stone is designed to be used specifically with natural stone such as granite and marble, especially light-colored varieties of granite which are prone to discoloration when too much of our NCF Quick is used. It has been tested on a variety of these sensitive granite types, and they did not discolor even when completely soaked with NCF Stone. However, NCF Stone should still be applied as a light mist- if the parts are becoming visibly wet, you are applying too much.
It is recommended using NCF Stone with all granite and marble, but especially with light-colored stones that may discolor with NCF Quick.
NCF Stone comes in a 6oz aerosol can. This accelerator is active for several minutes, so you can spray several pieces at once if you are making multiple bonds.
