1- Cutting: below steps explain how to cut granite:
- Firstly made the cutting board by attaching 1x2 pieces to a piece of OSB; this will support the granite and allow for space for the saw blade. Also ran two strips along the bottom as support.
- For large pieces, use a tile circular saw that has a water feed.
- Put tape on the tile to see marks.
- Mark the tile at 4 in off of where you want to cut to allow for the saw guide; mark a "V", it's much more accurate to align to.
- Clamp a piece of plywood as a straight-edge.
- Cut tile with the saw going pretty slow; and go real slow at the end of the cut, so you don't break the tile out.
- Lightly sand the cut edge using 220 grit to remove the sharpness, and make sure the sander is at a steep angle, so you don't scratch the polished surface.

2- Installing:
- Make sure the wood surface is totally flat, use a block plane to make sure every bump and imperfection in the plywood was planed flat. Also pay attention to where pieces of plywood come together.
- Build a small fixture to set the overhang of the granite. Granite is made of 1/2" plywood, with three pieces of tape to add a slight additional thickness for the glue.
- Dry fit the tiles first, start in the corner and work out. With large tiles, the best way to get a good corner is to do a miter and put an 18x18 in the corner.
- Apply polyurethane glue in line 1" apart.
- Install the tiles: corner is the toughest, since you need to get the overhang right on both sides.
- Once the tiles are in place, tape them together so they don't drift around as the glue foams and expands, and clamp the front across the joint to make sure everything is OK.
- Continue install the tiles.
- If needed to clamp the tiles in a back, try to put something heavy on them.
- Keep the joints really tight, basically butting the tiles next to each other. The chamber in the tiles will give a 1/16" joint, which will get filled with epoxy grout.

3- Install the Front Edges:
- Cut the pieces 1" wide with the tile saw and put a small bevel on the edges. Use polyurethane glue to attach and holding them in place with quick-grip clamps for 4 hours until the glue set.
4- Grouting:
- Grout the joints using Spectra-Lock epoxy grout. The joints are hardly noticeable, so mix 4 parts black with 1 part brown to match the stone color.
