How to Fix a Laminate Countertop in Under 3 Hours

Lifting stains and other eyesores off your existing laminate is a great way to revitalize your kitchen or bathroom countertops. Fortunately, one of the benefits of installing laminate countertops is they’ll be easy to clean.

A simple but effective cleaning solution you can use is to mix 1 tablespoon of baking soda with a few tablespoons of water. You want it to form a thick paste you can apply to the stained or discolored area. 

Allow it to sit on each stain for about 10 minutes, then wipe off the excess with a sponge or cloth. Laminate countertops can be damaged from hard scrubbing or brushing, so be gentle.

Scratched or chipped laminate countertops are pretty standard issues homeowners can experience. Fortunately, they’re relatively simple to repair. Homeowners have a choice: You can either buy a single tube of laminate filling solution (around $7 to $10) or a laminate or Formica repair kit (around $15 to $20). Both are available online and at home improvement stores.

The laminate repair kit will contain an application tool and around four different putties so you can mix and match the colors you need to fill. The directions on the package will explain how to do this. We recommend the kit if you have extensive designs that might look strange with an errant seal color.

If you know which brand of laminate countertop you have, it may be worth looking for a repair kit or putty/laminate paste made by the same company.

Many of us take the rigors our countertops face for granted. From knife cuts to hot objects being placed regularly on the surface, they truly do an excellent job of holding up to most stressors.

Sometimes, though, laminate can become loose, swollen, or warped in areas of high stress or use. If you put a hot pan down for too long in one place, for example, it could leave burns or even lift the material, leaving behind an unsightly bubble.

Laminate is secured to the plywood using contact cement or similar heat-sensitive adhesives. To fix this issue, carefully clean underneath the bubble to ensure no debris or air is trapped in the space. Make a small incision with your utility knife to let the air out, then use your iron to seal it back down.

The edges of laminate countertops can come undone from time to time as well. There are different tiers regarding the extent of repair you may need to do.

The first is the simplest: All you need to do is gently lift the laminate edge, then place a line of fresh laminate glue along the border. Press the laminate down to seal and let it dry. If it requires heat to activate, you may need to use your iron again.

But if the edging is seriously damaged and needs to be replaced, you’ll need to:

• Use your utility knife to score the damaged area that’s being fixed.

• Use an iron to warm up the laminate so you can remove it.

• Remove the piece of laminate.

• Put your replacement piece of laminate over the top to cover (some pieces come with glue or adhesive on the bottom already, while others may need it applied).

• Iron it on to seal.

Now that the hard work is done, consider giving your existing countertops an additional makeover. Laminate is relatively easy to paint over, which can provide a new life to your home’s kitchen or bathroom.

We recommend latex paint. One or two coats may be required, with adequate drying time in between. Assess after the first coat to see if a second is necessary. Sand down areas with scratches or dings that are noticeably deep to help create a smooth, glossy look once painted.
