How to repair a burn on laminate counter top

Updated February 21, 2017

Laminate countertops are a popular choice among homeowners because they are durable, easy to maintain and affordable. Unfortunately, laminate countertops are not impervious to damage, especially heat damage. Hot pots left to rest on laminate causes burn marks, as does a carelessly left cigarette or a candle that has burnt down too far. The repair method depends on the severity of the burn. Light burns are easier to remove than deeper burns, while very deep burns are irreparable. Laminate countertops, made from very thin layers of plastic heat-pressed onto kraft paper, as with any plastic, cannot withstand heat.

Wash the countertop with a mild degreasing detergent and rinse with plain water to remove dirt and debris from the burn mark and the surrounding area.

Place masking tape around the burn mark to protect the surface surrounding the damage.

Sand the burn mark with extra fine sandpaper until it is gone.

Choose a matching colour of laminate filler, which is a putty-like substance, used to repair chips, cracks, seams, holes and other damage on laminate.

Apply the laminate filler with a flexible plastic putty knife, smoothing it out and making it slightly higher than the existing surface.

Allow the filler to fully dry; drying times vary by manufacturer.

Sand the filler with extra-fine sandpaper to remove high spots and make it flush with the rest of the countertop.

Remove the masking tape and wipe up all dust with a damp rag.

Apply a coat of melamine paint with a low-nap roller to the patch to blend the colour with the existing surface, if the filler colour was not exact.

Tip

Bring a scrap piece of the laminate countertop to the store to match the colour with filler and paint. Consider replacing the entire countertop if the burn mark is large.
