Repair nicks, seams and gouges with ease. SeamFil bonds mechanically to the substrate of laminate. SeamFil dries hard, becomes a permanent part of the laminate surface. SeamFil resists moisture, detergents, and other household products, as effectively as the original laminate. In addition to standard joints, SeamFil works very well on cracks, chips and other imperfections where the dark substrate is visible. Properly used, SeamFil will hide defects beautifully for the life of the counter.
