Does My Granite Countertop Need to have Seams

Sep 17, 2019

For most natural stone kitchen countertops, seams where two individual stones are joined together — are often unavoidable. Sometimes it seems strange to some customers when they see the huge piece of stone their countertop will be made from. they are wondering why it can not just be cut in one piece. For smaller surfaces, like a bathroom vanity top or countertops with length within 110", a seamless countertop is usually workable, and also it looks nice without any seam. However, larger kitchen countertops present more of a challenge. Let’s go over why seams are often necessary and how good stone fabricators can minimize their appearance.

One of our clients got some trouble with the color or veinning matching for the seam as the picture:


but this job is from other factory with cheaper price, instead of our shop.

So this is what happened when you go with the "lowest price" - veinning does not match and the seam is horrible. Choose wisely. Cheap shops aren't good and good shops are not going to offer "rock bottom" pricing! 

This is the reason how the topic comes.

Why seams?

For starters, natural stone (particularly granite) is quarried with big blocks. And we cut big blocks to 2cm or 3cm slabs, normally the maximum length will be 110" for most of granite, only some granite can be 118". 

If you have a small kitchen countertop or just need a straight slab, it might be possible to cut it in one continuous piece. It really depends on the size of the countertop, the dimensions of the entryway and workplace, and also how many cutouts the stone will have. Cutouts, which you’d need for a sink or a cooktop, weaken the stone and can make the slab easy to get broken. In this case, seams may be necessary to ensure the stone doesn’t break apart.

These considerations are especially important for L-shaped countertops. These pieces almost always need to be cut in at least two pieces, which can be done in a few different ways. Sometimes the stone will be cut on either side of the corner, making two distinct rectangular pieces and a single short, straight seam. In other instances, the stone will be cut on a 45-degree angle from the corner, which creates a mitered seam. If the fabricator can get away with it, the seams may be placed in a more inconspicuous place, such as in sink cutouts, under a cabinet, or near a column.

Another factor that will impact how and where your seams are placed is the pattern and coloring of the stone itself. Stones that have fine graining and more consistent, even color are easiest to seam, especially if the stone is dark. The epoxy used to fill the seams is tinted to match the color of the stone, and since the epoxy itself usually has a yellowish tinge to it, it can be difficult to color-match on lighter slabs.

Slabs that have large swaths of color, wider ranges of color and intricate veining can be much more difficult to seam. In order to make the two pieces look as continuous as possible, we need to make sure that the color is relatively continuous from one piece to the next and that the veining and coloration continue to flow as naturally as possible. The pieces will look very distinct and somewhat sloppy and mismatched if the color changes dramatically between seams, or if the veining or patterning changes abruptly. While it’s not always easy to make a completely flawless transition, it's our work to make it look like one continuous piece of stone.

So the way to get a perfect seam, the most important is controling the color and veining match during our fabrication.
