Installation of hardwood floor on Gypcrete

Gypcrete is a durable and versatile flooring material commonly used as an underlayer for various floorings. When it comes to installing hardwood flooring, gypcrete provides an excellent base for a natural and aesthetically pleasing surface.

Installation Process for Hardwood on Gypcrete:

  1. Prepare the Surface: Before the installation process, ensure that the gypcrete surface is clean, dry, and in good condition. Remove any debris or loose particles, and address any cracks or damage present. It is important to have a smooth and level surface for the best results.
  2. Optional Sublayer: To further enhance the installation process, a thin sublayer such as asphalt paper can be laid over the gypcrete. This sublayer can help to provide additional moisture protection and ensure a smoother surface for the hardwood installation.
  3. Floating Hardwood Installation: Floating hardwood floors are typically the preferred method for installing over gypcrete. This installation method involves interlocking the hardwood planks without attaching them directly to the gypcrete surface. The floating installation allows for expansion and contraction of the wood due to temperature and humidity changes.
  4. Moisture Barrier: A moisture barrier sealer should be applied to the gypcrete surface before installing the hardwood flooring. This helps to prevent any moisture absorption that may potentially damage the wood over time.

Benefits of Installing Hardwood Flooring on Gypcrete:

  1. Ease of Installation: One of the significant advantages of installing hardwood flooring over gypcrete is the ease and cost-effectiveness of the installation process. By utilizing the existing gypcrete layer as the base, homeowners can avoid the time-consuming and costly process of removing the material and installing a subfloor layer of plywood. This makes hardwood installation over gypcrete a more convenient choice.
  2. Radiant Heating Compatibility: Gypcrete floors can be installed over a radiant heating system, making them an excellent choice for homeowners seeking energy-efficient heating. A thin layer of gypcrete can accommodate an engineered hardwood floor, offering a comfortable and warm surface. It is essential to apply a moisture barrier sealer to the gypcrete to prevent any moisture-related issues.
  3. Soundproofing Properties: Gypcrete has soundproofing qualities that help reduce noise transmission, particularly beneficial when installing hardwood flooring. The addition of gypcrete as an underlayer can effectively dampen the noise associated with walking on hardwood, creating a quieter living environment.


  1. Alternative Flooring Options: While hardwood installation on gypcrete is a viable option, it’s important to consider alternative flooring choices based on specific needs and preferences. Cement board, for instance, can be a less labor-intensive and equally suitable option for subfloor installation.
  2. Professional Assistance: It is advisable to seek professional guidance and expertise when considering the installation of hardwood on gypcrete. Professionals will ensure the proper preparation, choice of materials, and installation techniques are employed to achieve the best outcome.
