Can I Lay Laminate Flooring Over Carpet Padding?

Whether you're renovating your home or simply updating its flooring, understanding which surfaces laminate flooring can be installed over is crucial. Carpet padding, often found beneath carpeting, raises questions about its compatibility with laminate flooring. Here's a comprehensive guide to help you make an informed decision.

Compatibility Considerations

Generally, it's not recommended to install laminate flooring directly over carpet padding. The soft and yielding nature of carpet padding can create an unstable surface, leading to potential issues with the laminate flooring's stability and durability. The padding can compress under the weight of laminate planks, causing them to buckle or crack.

Potential Risks

Installing laminate flooring over carpet padding carries several risks, including:

Buckling and Cracking: Carpet padding provides insufficient support, leading to instability and potential damage to the laminate planks.
Moisture and Mold: Carpet padding can trap moisture, creating an environment conducive to mold growth, which can damage both the laminate flooring and the padding.
Voids and Unevenness: Carpet padding's irregular surface can create voids or unevenness beneath the laminate flooring, affecting its overall appearance and performance.

Exceptions and Alternatives

While installing laminate flooring over carpet padding is generally discouraged, there are some exceptions and alternatives to consider:

Thin Carpet Padding: If the carpet padding is very thin (less than 1/8 inch) and firmly attached to the subfloor, it may be possible to install laminate flooring over it with extra caution.
Underlayment Alternative: Instead of carpet padding, consider using a laminate flooring underlayment specifically designed for this purpose. Underlayments provide a stable and moisture-resistant base for laminate flooring.
Remove the Carpet Padding: The most recommended solution is to remove the carpet padding completely and install the laminate flooring directly on the subfloor for optimal stability and longevity.

Conclusion

To ensure a successful and long-lasting laminate flooring installation, it's important to consider the compatibility of the surface beneath it. While carpet padding generally does not provide a suitable base for laminate flooring, there may be exceptions in certain situations. However, the safest and most effective approach is to remove the carpet padding and install the laminate flooring on a properly prepared subfloor or underlayment.
