How To Fill Gaps In Laminate Flooring

Laminate flooring is a popular choice among homeowners because it is easy to install, cost-effective and durable. However, over time, gaps may start to appear between the laminate planks due to changes in temperature, humidity, or improper installation. These gaps not only ruin the appearance of your flooring but also make it vulnerable to moisture, which can cause the planks to warp or buckle.

If you have noticed gaps in your laminate flooring, don’t worry. In this article, we will guide you through the process of filling these gaps and restoring your flooring to its original beauty.

Step-by-Step Guide to Fill Gaps in Laminate Flooring

Before you start filling the gaps, you need to gather the necessary materials. You will need:

– Laminate floor gap filler
– Clean, dry cloth
– Handheld vacuum or broom
– Painter’s tape (optional)

Now, let’s get started.

Step 1: Clean the Floor

The first step is to clean the gaps and the area around them. Use a handheld vacuum or broom to remove any dirt, dust, or debris that may have accumulated in the gaps. Make sure the floor is completely dry before you proceed to the next step.

Step 2: Choose the Right Laminate Floor Gap Filler

There are different types of laminate floor gap fillers available in the market, ranging from silicone-based to water-based. Make sure to choose a filler that matches the color and texture of your laminate flooring. Most fillers come with a color swatch that you can use to find the closest match.

Step 3: Apply the Filler

Using a clean, dry cloth, apply the filler to the gap, making sure to fill it completely. You can use your fingers to press the filler down into the gap and smooth it out. If you are filling a large gap, you can use painter’s tape to hold the edges of the boards together until the filler dries.

Step 4: Wait for the Filler to Dry

The drying time of the filler varies depending on the brand and type. Typically, it takes around 24 hours for the filler to dry completely. During this time, make sure to avoid walking over the filled gap or placing any heavy objects on it.

Step 5: Sand and Clean the Surface

After the filler has dried, use sandpaper or a sanding block to level the surface and remove any excess filler. Be careful not to sand the surrounding laminate flooring. Once you have leveled the surface, use a clean, dry cloth to wipe off any dust or debris.

Step 6: Apply a Sealant (Optional)

If you want extra protection against moisture and wear, you can apply a laminate floor sealant over the filled gap. Make sure to choose a sealant that is compatible with your floor and follow the manufacturer’s instructions.
