Laminate flooring is known for its durability, but it can be chipped. While unsightly, chips don't require major repair. Laminate manufacturers, including DuPont, make repair kits specifically designed for chip repair. Fixing the chip as soon as you notice it will help keep your floor looking beautiful and in the best shape possible.
Determine the color of your floor by looking at a box your flooring came in. If the box is no longer available, find a leftover plank or take a clear photo of the chipped area of the floor.
Contact the store where you bought the flooring and purchase a repair kit matched to your flooring. They'll need the information from the box, or they'll need to see the sample or photo. If you don't know which store the flooring came from, call DuPont at 877-438-6824 to find a store near you that sells their flooring and repair kits. If a DuPont kit isn't available, get as close to the color as you can with a generic repair kit.
Sand around the chip with 300-grit sandpaper, smoothing out the edges and removing any loose material.
Clean the chipped area with a small amount of laminate floor cleaner on a rag or paper towels, then dry it thoroughly. Laminate floor cleaner can be found at home centers or hardware stores.
Apply the DuPont laminate floor repair putty from the kit to the chip with a putty knife, scraping it across the chip in a smooth, even motion. Keep spreading it until the surface of the repaired area is completely smooth. Wipe any excess off the floor. If you purchased a generic repair kit, you may need to mix colors to achieve a proper match. Laminate planks have several shades of color in them, so match the repair putty to the area immediately adjacent to the chip.
Allow the putty to dry according to the repair kit's instructions.
