Hiding Seams in Countertops

A solid countertop is rarely cut to cover cabinets that butt together in an L-shape. There are often at least two separate slabs of material used to form the countertop. If the slabs are not installed correctly, the seam between them will be visible. For concrete countertops, you can use grout to effectively hide the grout line. Seam lines in granite, stone and laminate countertops must be filled to help hide the gap between them.

Instructions

  1. Grout

    • 1

      Select a liquid grout pigment that matches the countertop. If your countertop is multicolored, match the middle color in the countertop. Mix the pigment with a light-gray seam grout in a container until it matches the intended color.

    • 2

      Smooth grout in between the seam line with a plastic scraper. Push the grout into the seam to fill the opening completely.

    • 3

      Wipe away any excess grout from the countertop with a wet sponge. The seam should become harder to see.

    Seam Sealer

    • 4

      Purchase a seam sealer compatible with your countertop (e.g., granite or Corian) and the color of your countertop.

    • 5

      Squeeze the sealer into the seam of the countertop.

    • 6

      Wipe away any excess sealer with a wet sponge. Then allow the sealant to dry in place. The seam will become harder to see.
