uneven seams

[todd]

Mark, I have a countertop seam that is flush in front and in the back of the top side of the granite but there is a 3/32 rise in the middle, is there a way to grind the seam flush all the way and then polish it back to the origanal factory shine?

this can be done with the right tools and someone with lots of experience. grinding granite seams to look factory is probably one of the hardest if not THE hardest things you can do in this industry. some guys make it look easy. theres special tools required. i would not recommend it to anyone that hasnt done it well before. most guys that do it charge 500 dollar minimum for seams.

Top polishing a seam is not for the beginner. A pro would use a wet polisher and either Alpha Twisttouch Turbo pads or Diamante Italia Shinepads to work the warp out of the stone and make it look right.

Do you have polishing experience?

yes i can polish, do you have any other suggestions on how to deal with this problem this is not the first time i have run into this problem its just the first time the customer wont except it

Lippage at a seam is caused by one or both pieces of granite at the seam getting warped. Top polishing is the cure. There really is no other alternative unless you want to build up the counter height with glue or take the warped slab off and lay it flat until (and if) it flattens out.

Nope...you have to top polish this!

Cameron, you're a pro...any other feedback?

3/32 is more than the accepted amount of lippage on the seam. and from the way you described it, higher on one side only in the back, it sounds like it couldve been installed better. either way it needs to be ground and top polished. a lot of people can use 4 or 5 inch velcro pads and resurface marble and even touch up some granite spots, but grinding a seam without leaving a dip or a wavy reflection is far far beyond that. i would definitely call in a pro. i might be able to help you find someone in your area. where are you located? if you decide to try this yourself, you may end up with more headaches than you have know. i never like to discourage people, but this is not something that is done often, and theres not many people that can do it properly. its not a fun situation to be in but youl definitely learn from it.
