What Goes Under Wood Flooring

There are two main options for what to put under wood flooring: plywood or underlayment. Plywood is a type of engineered wood that is made from thin layers of wood that are glued together. Underlayment is a thin layer of material that is placed between the subfloor and the wood flooring. It helps to smooth out any imperfections in the subfloor and to provide a cushion for the wood flooring.

If you are installing wood flooring over a concrete subfloor, you will need to install a moisture barrier between the concrete and the wood flooring. A moisture barrier is a thin layer of material that helps to prevent moisture from rising up from the concrete and damaging the wood flooring.

The type of underlayment that you choose will depend on the type of wood flooring that you are installing. Some types of wood flooring, such as laminate flooring, require a specific type of underlayment. Other types of wood flooring, such as hardwood flooring, can be installed over a variety of different types of underlayment.

Once you have chosen the type of underlayment that you want to use, you will need to install it according to the manufacturer's instructions. Most types of underlayment are installed by rolling it out over the subfloor and then taping the seams together.

Once the underlayment is installed, you can begin installing the wood flooring. Wood flooring is typically installed by nailing or stapling it to the subfloor. The type of nail or staple that you use will depend on the type of wood flooring that you are installing.

Once the wood flooring is installed, you can finish it by applying a sealant or finish. A sealant or finish will help to protect the wood flooring from damage and will make it easier to clean.

Here is a more detailed look at the different types of underlayment that are available:

Felt underlayment is a type of underlayment that is made from felt. It is a relatively inexpensive option and it is easy to install. However, felt underlayment does not provide as much cushioning as other types of underlayment.
Cork underlayment is a type of underlayment that is made from cork. It is a more expensive option than felt underlayment, but it provides more cushioning and it is also soundproof.
Rubber underlayment is a type of underlayment that is made from rubber. It is a very durable option and it provides excellent cushioning. However, rubber underlayment is also the most expensive type of underlayment.

The type of underlayment that you choose will depend on your budget and your needs. If you are looking for an inexpensive option that is easy to install, felt underlayment is a good choice. If you are looking for a more durable option that provides more cushioning, cork or rubber underlayment is a better choice.
