How to Repair a Laminate Countertop

Updated February 21, 2017

Laminate countertops come in different finishes, such as plastic and wood. When a large scratch or dent appears from a heavy item dragged or dropped on top of the laminate, a repair is needed to restore the countertop finish. If the imperfection is left alone, the laminate may appear worn and old. Repair scratches and dents in laminate using the correct products and procedures.

Spray a kitchen cleaner on the laminate and wipe crumbs and dust from the surface with a damp cloth. Dry the laminate with a clean cloth.

Fill scratches or small dents in the laminate with a seam filler. Squeeze a light coat, approximately 1/16 inch thick, into the scratch or dent on the laminate countertop. Continue applying light coats, filling the scratch or dent to the surface of the laminate.

Wipe around and over the top of the filled scratch or dent with a damp cloth to remove excess filler. Allow the filler to dry for 24 hours.

Wipe dust from the scratched or dented area of the wood laminate with a damp rag and dry with a clean cloth.

Fill the scratch or dent with a filler made specifically for wood laminate countertops. Place a fingertip-sized amount of the wood filler onto a damp rag and wipe it into the affected area. Continue filling the area with the wood filler until it is flush with the rest of the countertop. Remove excess wood filler from the surrounding areas with a damp rag.

Pour a dime-sized amount of clear finish on a clean cloth, and wipe over the top of the filled-in areas of the wood laminate countertop. Allow the area to dry for 24 hours before working on the surface.


Match the plastic laminate seam filler and wood laminate filler as close as possible to the colour of your laminate countertops.
