The other problem is that can be a spot that attracts kitchen grime. That’s why it is important to know how to conceal them from view if you want to make the room more appealing. Without further ado, let’s have a look at different methods on how to hide the seams of laminate countertops.

How to Hide Seams in Laminate Countertops

Things You Will Need

To start this simple DIY project, you need to find the appropriate seam filler. When buying a seam filler, you need to choose one that blends in perfectly with your laminate countertop to get a flawless look.

There are a number of different brands on the market to choose from, and they all come in a wide range of colors and shades. That allows you to use seam fillers on just about any design of laminate countertops. For this project, you will also need the following tools and items:

How to Hide Seams in Laminate Countertops with Seam Filler

Step 1: Prepare the Seam

Once you have chosen the right seam filler and collected all the things needed, you’ll be all set for the first step of your project. It involves preparing the seam.

The preparation is intended to make the seams free of any dirt, dust, and crumbs, which is necessary to make the filler effective. When lodged in the seams, these particles keep the filler from adhering well. Here’s how to prepare the seams properly:

  • First, you will need to brush along (not across) the seam with a soft bristle brush. Thus, you will remove dust, dirt, and other residues.
  • Then scrape out the seam using a putty knife to dig out unwanted particles that didn’t come off.
  • After that, you need to use your brush again. Brush away the debris to move them off your laminate countertop.
  • Now you should pour some acetone on a clean cloth or rag and clean the countertop seams by wiping them down. Not only will acetone help eliminate dirt, but it will also make it easier for the putty or filler to bond.
  • You may also use laminate countertop cleaners. Aside from removing grease, grime, and food deposits, these cleaning solutions can help surfaces resist staining by creating a protective coating. Lastly, polish with a paper towel.

Step 2: Prepare the Seam Filler

After making your countertop ready, it’s time to get the seam filler prepared too. For this purpose, you’ll need a plastic bowl or plate. It’s quite easy. Just follow these easy steps:

  • Place a small amount of your putty or filler onto the container or surface that is suitable for mixing the seam filler.
  • Next, mix the filler with the color (or a few different colors) using your putty knife. The goal is to make the color consistent and ensure that it matches the laminate surface.
  • When it comes to multi-colored countertops, it’s recommended to test the colors before application. Mix and match the right ones until you get the shade that fits in with your countertop.
  • If you have marble laminate, then you’ll have to mix two colors for two-tone marble, or three colours for three tone marble. That is how you can prepare the colours for this type of countertop.

Step 3: Fill the Seams

Scoop the seam filler onto the putty knife and apply it to the seam. To do this correctly, you need to drag it across (not along) the seam. This way the filler will be caught in the proper places. Repeat this easy step till the seams in your countertop are filled altogether.


  • Be careful when filling the seams because all the sealers tend to shrink a bit as they dry.
  • Since the filler dries up very quickly, it should never be left out for more than three minutes.
  • You may also use your fingers to fill the seams while going through them, especially when working in hard-to-reach areas.
  • In order to keep the job clean and prevent the filler from smearing onto laminate, use small amounts at a time. It is the best way to go.
  • This job usually requires a few applications, so you’ll probably have to apply more than one coating to completely fill the gaps.
  • When finished, the sealer should be even with the surface of your countertop. So Before it dries, level the top thoroughly. Make sure it lines up perfectly with the top.

Step 4: Scrape the Seams

There will be excess filler after filling the countertop seams. So you will need to scrape it off the surface using the putty knife. The proper way to do this job is to scrape along the lines, i.e., toward the seams.

  • Take your putty knife and hold it flat on the laminate so that it’s level against the surface. This means it should be horizontal while you’re scraping the seams.
  • Avoid scraping across the top because the filler can easily be removed from the seams. That will bring you back to the previous step.
  • Level the filler by dragging the putty knife along (actually its edge) along the path. If you pull it vertically across the seams, the blade will ruin the nice job you’ve just completed.
  • When you stop working with your putty knife, keep it clean with acetone. This will prevent the filler from hardening, which will make it more difficult for you to fill the seams.

Step 5: Clean your Seams Again

Have you finished the leveling? Great! Now it’s time to get rid of excess filler. This means to wipe it off your laminate with a soft brush.

Once you’ve scraped and brushed away the dried seam filler, you will have to clean the surface again. Grab a rag and dampen it with acetone for the best cleaning results.

Give your countertop a good clean-up, taking special care of the area around the seams. Lastly, polish it with paper towels.
