cnc and resin

[john b]

Need some input on when to apply resin on some granites , after what diamond is application used. Do you dry the stone off or just wipe it on. Should I wait until piece is finished then resin. Appreciate any help.

Hey John glad to see you on here. I assume your referring to donnified slabs where edges that need to be darkened? What product are you using? Tenax Ager is usually the product of choice around here. I'm not sure if you deal with Peter from Stone Friend but he gave me some Ager knock off made by some Italian company called general, I ran into some consistency issues and have abandoned it. Anyway back to the edges, I find that for most granites applying the ager after the polishing process is sufficient. Are you using the cnc for a full polish? Or are you finishing by hand? For the more porous stones applying the ager after 800g sometimes is more effective.

Hey Alex, good to hear from you.We use tenax and applied it after 400 diamond, but since we just started working on the machine i'm not sure when to use it. We are bringing stones to a complete polish, just figured someone would say use it here ---done

cnc has a different set of rules. You cannot stop the machine dry it and apply anything, so you are stuck with doing it after the fact. We stain the edges of all of our stuff on install. This is because it is not dry until it is stacked on the cart. If the edges are real bad and we don't want the customer to see it, we do it while we are loading for install.

We use lots of stuff, depends on the stone....tenax ager, aquamix stone enhancer, tenax dyes, minwax wood stain.

Some stones these days are being resined with dyed resin. In most of the cases it is necessary to use the tenax tepox dyes.

I have run across only a couple jobs in the last 5 years that I could not get a perfect match on after the fact, and this was before tepox came to market.

Warming the stone causes the dye to go in easier as it makes the fluid less viscous and expands the pores in the stone all at the same time.

It is very important to only to apply to thoroughly dried stone BEFORE any sealer is applied.
