For bamboo flooring, it is recommended to use an underlay with moisture barrier properties, such as a high-quality foam or cork underlayment. These materials provide stability, sound absorption, and protection against moisture, enhancing the longevity and performance of bamboo flooring.
If you are nailing down bamboo flooring
If you’re nailing down bamboo flooring instead of floating it, you’ll want an underlayment that primarily provides moisture protection and minimizes sound transmission. While foam underlayment is commonly used for floating floors due to its cushioning and sound absorption properties, it’s not typically used when nailing down flooring.
For nail-down installations of bamboo flooring, you’ll want to focus on underlayments that offer the following characteristics.
Choose an underlayment that includes a moisture barrier or vapor retarder to protect the bamboo flooring from moisture rising up from the subfloor. This is especially important if you’re installing over concrete or in areas prone to moisture.
While not as critical as with floating floors, some level of sound reduction can still be beneficial, especially in multi-story buildings or areas where noise transmission is a concern. Look for underlayments that provide moderate sound absorption properties to minimize impact noise.
Opt for an underlayment that is thin enough to not interfere with the nail-down installation process but still provides sufficient cushioning and support for the bamboo flooring. Thicker underlayments may affect the depth of the nail penetration and the stability of the flooring.
15 lb. Asphalt-Saturated Felt Paper: Asphalt-saturated felt paper is a traditional underlayment material commonly used in nail-down hardwood flooring installations. It serves as a moisture barrier, helps to reduce squeaks, and provides a smooth surface for the flooring to be nailed onto. It’s relatively inexpensive and readily available at most hardware stores.
Rosin Paper: Rosin paper, also known as builder’s paper, is another traditional underlayment option for nail-down hardwood and bamboo flooring installations. It provides a moisture barrier between the subfloor and the bamboo flooring, helping to prevent moisture-related issues such as warping or cupping. Rosin paper is lightweight, easy to install, and offers some degree of sound absorption.
Aquabar “B” Underlayment: Aquabar “B” is a premium-grade underlayment specifically designed for use under hardwood and bamboo flooring in nail-down installations. It consists of two layers of kraft paper laminated with asphalt to provide a moisture barrier. Aquabar “B” offers excellent moisture protection, sound absorption, and smoothness for the flooring to be nailed onto. It’s suitable for use over concrete and wood subfloors.
Silent Guard Cork Underlayment: Silent Guard Cork Underlayment is a high-quality underlayment option that combines the benefits of cork with added moisture protection for nail-down bamboo flooring installations.
