granite countertop

Seams in granite countertops are glued together using two-part epoxy. A special clamping system, known as a seam puller, uses a vacuum pump to attach blocks to each half of the countertop. The two sections are then pulled together with lever operated clamps until the glue sets.

  1. I have no alternative but to replace kitchen base cabinets and want to salvage the granite countertops. What is best way to remove granite tops that are seamed together so as not to break granite.

  2. I am looking for an inexpensive way to get a granite look. I have found tiles 18 x 31 with polished edges. Can these be seamed by using the 2 part epoxy or do I have to use grout? I am trying to make it less noticeable.

    • Hi Kathleen,
      I don’t see why you couldn’t join the granite together using standard two-part epoxy glue, if you clamped it securely while it dried, though I have never tried it. You could probably add a bit of powdered universal colorant to the glue to make the seam less noticeable. Good luck with your project!

  3. what is the best way to break a seamed joint on a granite counter top with out damaging as I want to reuse countertops but reconfigure them?

  4. I want to know the specific name of the epoxy that is used to join the granite seams. We are redoing our kitchen and working with a very tight budget so we are going to do the installations ourself.

    • Hi Jamie,
      I don’t know of any solvent that dissolves cured epoxy, but I’ve heard you can heat granite with a heat gun then apply outward pressure with vacuum clamps or by driving wood shims in the joint to separate them, but I haven’t tried it myself.

  5. I had a granite countertop install that went wrong & had to be removed. The installer separated the seam by heating the seam from underneath using a propane torch, this basically melted the epoxy in the seam until it dripped like wax & any remaining epoxy was ground off before reinstallation of the granite.

  6. I am having trouble locating a place which rents seam setter/seam puller.
    I’ve checked several rental places and one recommended a tile store – no luck.

    Chicago area or Benton Harbor/Kalamazoo MI area
    Any pointers would be appreciated.

  8. want to build a small bathroom vanity for a vessel round sink .6″ hx18″x20″ will epoxy hold this together it will be wall mounted,

  9. I am having a granite countertop installed and it has to be pieced. The installer wants the seam to be in the middle of the sink opening. That seems problematic to me. Where is the best place for a seam on a long countertop?

    • Hi, Suzanne,

      Danny says, “It is very common to seam granite countertops at the sink. It is less obvious, inconspicuous and it hides the seam better because it’s simply shorter. It rarely proves problematic. That’s what I have at my house!

      Good luck!”
