What if there are gaps between SPC flooring planks after installation?

Jul 30, 2025Leave a message

Hey there! As a supplier of SPC flooring, I've come across many customers who've faced a common issue: gaps between SPC flooring planks after installation. It's a bummer when you've invested time and money in a beautiful floor, and then these gaps show up. But don't worry! I'm here to break down why this happens and what you can do about it.

Why Do Gaps Appear?

1. Incorrect Installation

One of the most common reasons for gaps is improper installation. If the planks aren't locked together tightly during installation, gaps are bound to appear. Sometimes, installers might be in a hurry or not have enough experience. For example, if the click - lock system isn't engaged properly, the planks won't stay snug.

Another aspect is the underlayment. If the underlayment isn't flat or smooth, it can cause the planks to shift and create gaps. It's super important to make sure the subfloor is clean, dry, and level before laying the underlayment and then the SPC flooring.

2. Environmental Factors

SPC flooring can expand and contract with changes in temperature and humidity. If your room has extreme temperature fluctuations or high humidity levels, the planks may expand when it's humid and contract when it's dry. This constant movement can lead to gaps over time.

For instance, in a bathroom or a basement where humidity is usually higher, the chances of gaps forming are greater. And if your room has direct sunlight coming in through windows, the heat can also cause the planks to expand unevenly.

3. Quality of the Flooring

Not all SPC flooring is created equal. If you've bought low - quality SPC flooring, it may not have the proper density or stability. Cheaper planks might be more prone to warping or shrinking, which can result in gaps. When you're looking for SPC flooring, make sure to choose a reliable supplier and check the quality certifications.

How to Fix the Gaps

1. For Small Gaps

If the gaps are small, you can try using a flooring filler. There are special fillers available in the market that are designed to match the color of your SPC flooring. First, clean the gaps thoroughly to remove any dirt or debris. Then, apply the filler according to the manufacturer's instructions. Use a putty knife to smooth it out, and let it dry completely.

2. For Larger Gaps

If the gaps are large, you might need to remove and reinstall the affected planks. Start by carefully prying up the planks around the gap. Make sure not to damage the adjacent planks. Once the planks are removed, check the underlayment and the subfloor for any issues. If everything looks good, clean the planks and reinstall them, making sure to lock them together tightly.

3. Adjust the Environment

To prevent future gaps, you can try to control the temperature and humidity in your room. Use a dehumidifier in humid areas like bathrooms and basements. And if your room gets a lot of sunlight, use curtains or blinds to block the direct heat. Maintaining a stable environment will help keep your SPC flooring in good condition.

Preventing Gaps in the First Place

1. Professional Installation

Hiring a professional installer is always a good idea. They have the skills and experience to install the SPC flooring correctly. A professional will make sure the subfloor is prepped properly, the underlayment is laid evenly, and the planks are locked together tightly.

2. Choose the Right Flooring

As I mentioned earlier, the quality of the flooring matters. Invest in high - quality SPC flooring from a reputable supplier. Our SPC flooring products are made to withstand normal wear and tear and environmental changes, reducing the risk of gaps.

3. Leave Expansion Gaps

During installation, it's important to leave expansion gaps around the perimeter of the room. These gaps allow the planks to expand and contract without causing gaps in the middle of the floor. The size of the expansion gap depends on the size of the room and the type of SPC flooring, but usually, a 1/4 - inch gap is a good starting point.

Conclusion

Gaps between SPC flooring planks after installation can be a hassle, but they're not the end of the world. By understanding the reasons behind the gaps, you can take steps to fix them and prevent them from happening in the future.
