How to Install the Seams in a Granite Counter
Granite serves as a resilient and strong surface for countertops, resisting scratching, staining and moisture damage as long as it is properly sealed and cared for. Many countertops will require two pieces of granite to be joined together to cover the whole area, and the seam between the two joining pieces can be a vulnerable spot in the tough granite fixture if not properly installed and sealed. Does this Spark an idea?
Things You'll Need
- Level
- Shims
- Masking tape
- Polyester glue
- Color additives
- Glue hardener
- Putty knife
- Razor blade
- Steel wool

1
Set the two granite pieces in place on the counter surface. Push them together until they are at most 1/16 inch apart.
-
2
Set a level on top of the two pieces to ensure that they sit at exactly the same height. If necessary, use thin wooden shims slid under one side or the other to achieve perfect level. Check level at the front, middle and back of the counter so that it is completely flat at all points. If you need shims, you'll probably need them at all three points of the counter.

3
Mask the surface of the stone around the seam with masking tape to prevent getting the seam glue on the granite pieces themselves.
-
4
Mix two-part polyester glue and coloring additives per product instructions until you achieve the color you want to use for your seam. Once you have the right color, add the glue's hardener per product instructions. The hardener will help the glue dry quickly.
-
5
Spread the glue into the seam. Many glue products come with a tube from which you can squeeze, or you can spread the glue into the joint with a putty knife. Fill in the entire seam, then run a putty knife down the length of the seam to scrape off high points. Fill in any gaps as necessary and allow the glue to dry per product instructions.
-
6
Remove the surrounding tape. Use a thin razor blade to scrape off any excess glue from around the seam.
-
7
Sand the seam with 0000-grade steel wool to add a slightly rough texture and help the seam blend with the stone.

Tips & Warnings
The two pieces of granite that meet at a seam must be cut completely smooth at the adjoining edges.
Follow glue instructions for mixing carefully, as the ratios for the two parts and the hardener will vary by product.
