How to Fill Huge Gaps in Floorboards (Laminate)

Laminate flooring is a popular choice for many homeowners due to its affordability, durability, and ease of installation. However, over time, gaps may develop between the floorboards, especially if the subfloor is uneven or if the flooring material has shrunk or expanded with changes in humidity. Filling huge gaps in laminate floorboards can be a challenging task, but with the right techniques and materials, you can achieve professional-looking results. In this article, we will guide you on how to fill huge gaps in laminate floorboards.

Prepare the Area

Before filling the gaps, ensure the area is clean and clear of any debris, dust, or old adhesive. Sweep the floor to remove any dirt, dust, or other particles. If there are any old gaps or cracks in the floorboards, use a utility knife to widen them slightly to allow for better filling.

Choose the Right Filler

There are several types of fillers you can use to fill huge gaps in laminate floorboards, depending on the size and depth of the gap. Some common fillers include:

• Epoxy-based wood filler: A strong and durable filler suitable for large gaps. It comes in a putty-like consistency and can be tinted to match the color of your laminate floor.
• Acrylic-based caulk: A flexible and weather-resistant filler suitable for gaps of up to 1/2 inch (13 mm) wide. It’s easy to apply and dries quickly.
• Polyurethane-based foam sealant: A lightweight and non-shrinking filler suitable for gaps of up to 3/4 inch (19 mm) wide. It’s perfect for filling larger gaps and expands to fill small gaps.

Filling the Gaps

Once you’ve chosen the right filler, it’s time to fill the gaps. Follow these steps:

1. Cut the Filler: Cut a small amount of filler to match the size of the gap.
2. Apply the Filler: Apply the filler to the gap, using a putty knife or caulk gun, depending on the type of filler you’re using. Press the filler firmly into the gap to ensure it’s fully seated.
3. Wipe Excess Filler: Use a damp cloth or paper towel to wipe away any excess filler that has spilled outside the gap.
4. Allow to Dry: Let the filler dry according to the manufacturer’s instructions, which is usually between 15 minutes to an hour.
5. Sand the Area: Use a sanding block or sandpaper to smooth out the filled area, feathering it out towards the surrounding laminate floorboards.
6. Apply Additional Coats: Depending on the depth of the gap, you may need to apply additional coats of filler, allowing each coat to dry before applying the next.
7. Seal the Filler (Optional): If you’ve used a fillers that don’t match the color of your laminate floor, you can seal the filled area with a touch-up marker or a clear lacquer to ensure a seamless finish.

Additional Tips

• To ensure a strong bond between the filler and the laminate floor, make sure the floor is clean and free of dust, dirt, and old adhesive before filling the gap.
• For larger gaps, you may need to use multiple layers of filler, allowing each layer to dry before applying the next.
• To prevent further gaps from developing, ensure the subfloor is level and securely fastened to the walls to prevent movement and shrinkage.

Conclusion

Filling huge gaps in laminate floorboards may seem like a daunting task, but with the right techniques and materials, you can achieve a professional-looking finish. By choosing the right filler, preparing the area, filling the gaps, and applying additional coats as needed, you’ll be able to fill even the largest gaps in your laminate flooring. Remember to follow the manufacturer’s instructions and take your time to ensure a strong and lasting bond between the filler and the laminate floor.
