I will be using Silestone for splashbacks/window sills and may need to trim it.
Cutting & Trimming-
I was using a borrowed Husky 7" wet saw. The stone is 1-1/4" thick and that saw's depth of cut was 1-1/4". It was just barely enough to get through. So when I was starting out, it was getting chipping on that top edge, it was taking forever and it was hard to get a straight edge or square corners. It was all by "eye." To get a bevel, half the table tilt's and you had to hld the stone steady above the blade. No fence. It was a struggle and took a long time. Once I got to fitting the stone, it was taking forever.
HF had a sale on their 2-1/2 hp commercial 10" wet saw. Over $150 off. I broke down. Everything was a lot faster and easier. If you are trying to trim off just a slight angle with a diamond blade in thick granite, there is a lot of blade flex. That saw, besides the sliding table, you can vary the depth of cut and or use it like a chop saw. Made things possible and it was easy to square things up better.
Cleaning up the edges-
Granite and marble you put a slight 45 degree bevel on the top edges to clean them up. With ceramics and suck you can just take a carborundum rub stone for a masonry file wile carborundum) and a few swipes and you're good. Granite and marble is harder. I started out with using a sanding pad with 40 grit wet/dry (metal) belting and a diamond stone by hand. It was taking my forever. I took hours and I didn't feel like I accomplished much.
I broke down and bought a diamond turbo cup for my 4-1/2" angle grinder. Made that quick work. A pass or two at 45 degrees on each edge. A couple hours and I was done.
-- Funny how making tiles with thick stone ends up more like precision brick and block work. And I wanted to get accurate thin grout lines between, so it's been taking a while. This all would be all different if this was just thin lighter ceramic or softer stone tiles. Even with using thinner marble or granite. I used to help my partner who was a tile guy (cutting for him while he laid). I've done some tile work on my own after that. But, I'm thinking "tile work" is easy after doing this. I've learned a lot.
Granite and Marble slab starts out as 1-1/4. That is what stays as the edges of a counter. From there, for a counter, they thin out (plane) all but the edges, so what sits on the counters is 3/4" thick.
EDIT-- Notice the duct tape over foam rubber? First night I had the counter base installed, Sharon gouged her back on it, trying to cut the corner. I forgot she has a habit of that. The island counter edgebanding I have rounded "for her." That is my safety measure until the edgebanding is on there...
