Seaming two pieces of granite

[MartinTravels]

The DeFuco video on glues and sealers was very helpful.  It answered all my questions about making the seam strong, flat, watertight, and as invisible as possible.  But how do you recommend cutting the edges of the two slabs to be joined?  Should they be cut once with a diamond blade, or should they be sanded and polished like a finished edge?  What about the top edges of the two slabs of granite?  Should I round/polish them a little, or should I leave them kind of rough and as close to a sharp right angle as possible?

Thanks for all the help in answering my questions,

The answer is - it depends!

When I cut slab I like a tight comb turbo blade to get as smooth a cut as possible, but if there are burrs at the top of the cut edge I hit those with a polishing pad just to smooth them out. I do not waste time polishing an edge that will not be visible, and neither should you. If you hit the sharp high spots with one of the finer polishing pads it should do the trick for you.

If you want to discuss this call me at the office during the week at 800-289-6834.

Glad to be of service,
