Choosing the right underlayment is key to a successful laminate or vinyl plank flooring installation. We often receive questions about whether flooring can be installed over existing carpet padding. As a rule of thumb, we do not recommend this practice. Installing laminate or vinyl plank flooring over carpet padding can result in issues and potentially harm your flooring in the long run.

To ensure a successful installation and to guarantee the durability of your flooring, it is always best to opt for an underlayment that is specifically designed for your type of flooring and subfloor. This way, you can enjoy your beautiful new flooring for years to come.

Why Can’t I Use Carpet Padding?

Generally speaking, carpet padding is too thick to be used with laminate or vinyl plank flooring.

Floating floors, such as laminate or vinyl, require proper underlayment to float. Underlayment is what allows the floor to float on top of the subfloor. It provides some cushioning to the floor and allows it to expand and contract smoothly with the changes in temperature and humidity. Choosing the right underlayment is a critical part of a successful flooring installation.

It’s a common misconception that adding extra padding will make your floor softer to walk on. While thicker padding does provide more cushioning, it can actually damage the locking system of your flooring. Think of it like placing a thick sponge under your flooring – too much padding can create instability and cause permanent damage.

It is important to also pay special attention to your warranty when installing underlayment and flooring, as not using the recommended padding can void the warranty coverage.

Choosing The Right Underlayment

Finding the perfect underlayment for your project is crucial. To determine the best option, consider your flooring type, subfloor, and personal preferences. With various underlayment choices available, we encourage you to check out our Ultimate Guide to Laminate Flooring Underlayment.

When removing carpet, it’s important to strip everything down to the subfloor. To ensure a successful installation, prepare your subfloor by thoroughly cleaning it and ensuring it’s level. Proper preparation and the right underlayment is essential for a successful installation and will allow you to enjoy your flooring hassle free for years to come!

can I leave carpet padding , lay 1/4 osb underlayment and lvt with cork backing?

Thanks for your question, Phil. If your lvt has cork underlayment attached, you should not use an additional underlayment. As for the carpet, this will depend on if it is a low pile commercial carpet. If yes, you can install on top. If this carpet is thicker, you will want to remove before installing your vinyl flooring. However, we would suggest contacting the manufacturer of your flooring so you can be sure before installing!
