When it comes to granite, quartz & marble countertops, seams are necessary to cover the entire space. Seams also help to maximize the strength of the stone in, particularly weak spots. Owing to the fact that seaming involves two pieces of heavy stone, it is not uncommon to receive shoddy work. Nothing can take away the beauty of your stone countertops faster than a noticeably thick line connecting the two slabs or a sudden alteration in color or pattern.
In the case that your kitchen has a large island or a long strip of counter space, it is imperative that you receive excellent craftsmanship. Maintaining a flat, smooth surface is one of the first steps in ensuring an almost invisible seam. You must make sure your cabinets are leveled. They have to be strong enough to support the pieces of stone.
Selecting certain colors and patterns is necessary to avoid an unsightly seam. Lighter stones allow the connecting line to be more visible to yourself and guests. Dark stones, particularly black stones, make the line far less noticeable. Stones with unique patterns and inconsistent designs are difficult to properly seam together because the intricate veining may not properly match up. When selecting which stone to use if covering a large space, it is best to choose one with a repetitive pattern. The consistent pattern and direction of the designs contribute to making the seam more invisible.
A key factor to hiding a seam is placement. Smaller seams are simply more difficult to notice. Seams should be placed in “hidden” spots such as, around a sink or underneath a cabinet. Another factor to consider is lighting. Seams should never be placed directly under a light. This draws more attention to the particular spot and allows details to be seen more clearly.
