Laminate Countertop Seam Filler. Squeeze some seam filler onto a paper plate or a spare piece of laminate. Allow the repaired area to dry completely.
SeamFil can repair nicks fill seams and make gouges disappear with this one-part system. Each brand of laminate sealer comes in a variety of different colors. Otherwise it will harden and leave rough spots.
I was pleased at how well it did the job.
Seams can also happen in corners where two sections of countertop join in order to produce an L shape. If the seam is wider than 116 but should never be larger than 18 a second application will probably be necessary. It resists moisture detergents and other household products as effectively as the original laminate. Allow the repaired area to dry completely.
