Imagine: you’re finally installing that beautiful new laminate floor. You’re excited about its sleek look, durability, and budget-friendliness. But then a question pops up: “Can I use carpet padding underneath?” It seems like a logical solution, right? After all, it’s designed to cushion things. But before you rush out to buy padding, let’s take a closer look at the implications.

This question isn’t just about aesthetics. It’s about the longevity and performance of your laminate flooring. Choosing the right subfloor and underlayment can make or break the entire project. So, let’s dive deep into the specifics to understand why using carpet padding under laminate flooring might be a good idea, but often a risky one.
The Science of Laminate Flooring
Laminate flooring isn’t actually wood. It’s a multi-layered composite, with a durable wear layer printed with wood-like patterns and textures. This layer is then bonded to a core of high-density fiberboard. The key to laminate’s success is its stability. It’s designed to stand up to daily wear and tear without warping, cracking, or buckling.
Why Carpet Padding Might Seem Like a Good Idea
The appeal of using carpet padding under laminate is simple: it promises comfort and sound insulation. It can make a room feel warmer and quieter, especially in homes with concrete subfloors. But that’s where many misconceptions arise.
The Risks of Using Carpet Padding Under Laminate
Here’s the catch: carpet padding is designed to cushion the impact of foot traffic, not to provide a stable foundation for rigid materials like laminate. Here’s why carpet padding can jeopardize your laminate flooring:

1. Moisture Issues
Carpet padding is often made from materials that readily absorb moisture. This can create a breeding ground for mold and mildew, especially in areas prone to leaks or spills.
2. Uneven Subfloor
Despite its name, carpet padding doesn’t actually “pad” the subfloor. It simply sits on top, potentially exacerbating existing unevenness. This uneven surface can lead to gaps in the laminate flooring, creating tripping hazards and compromising its look.
3. Warping and Buckling
The softness of carpet padding can cause laminate flooring to warp or buckle over time. The weight of furniture or constant foot traffic can compress the padding, creating uneven pressure on the floorboards. This can also lead to premature wear and tear on the laminate’s surface.
4. Click-Lock Systems
Laminate flooring often utilizes a click-lock system, allowing for easy installation and disassembly. This system relies on a snug fit and a smooth, hard subfloor. Carpet padding can interfere with this fit, causing instability and potential loosening of the planks.
5. Voiding Warranties
Most reputable laminate flooring manufacturers explicitly state in their warranties that using carpet padding as underlayment voids the warranty. This is because they know the potential for damage is high, and they aren’t liable for problems that arise from using an unsuitable underlayment.
What’s the Right Underlayment for Laminate Flooring?
If you’re aiming for maximum durability and longevity, choosing the right underlayment for laminate flooring is crucial. Focus on materials that are durable, moisture-resistant, and stable. Here are a few popular options:
1. Foam Underlayment
Foam underlayment offers good sound insulation and cushioning, with varying densities available for different levels of impact absorption. It’s important to choose a foam underlayment specifically designed for laminate flooring, as it’s moisture-resistant and provides a stable base.
2. Cork Underlayment
Cork underlayment is an excellent choice for its natural moisture resistance and sound insulation qualities. It’s also eco-friendly and provides a surprisingly comfortable feel underfoot.
3. Vapor Barrier
If your subfloor is prone to moisture issues, a vapor barrier should be installed underneath the underlayment. This prevents moisture from migrating upward and affecting the laminate flooring.
Expert Tips for Choosing the Right Underlayment
Consult with an experienced flooring professional or visit your local flooring store for personalized advice. They can help you choose the right underlayment based on your specific flooring needs, subfloor conditions, and budget.

Conclusion
While the idea of using carpet padding under laminate flooring may seem tempting for its added comfort and sound insulation, it often outweighs the potential risks of moisture issues, warping, and voiding warranties. Investing in the right underlayment, specifically designed for laminate flooring, ensures a stable and longer-lasting installation. Before you make your choice, educate yourself, seek advice from experts, and prioritize the long-term health and beauty of your new laminate floor.
