In this article, we will explore the uses, benefits, and considerations of using tar paper as an underlayment for tile installations.
Understanding Tar Paper:
Tar paper is a moisture barrier made from a combination of bituminous material and a thick, woven fabric. It is designed to protect underlying structures from water infiltration. Tar paper is commonly used in roofing applications to prevent water from seeping through the roof and causing damage. It is an affordable and easily accessible material that offers excellent protection against water and other potential sources of moisture.
Benefits of Using Tar Paper:
- Moisture Protection: The primary benefit of using tar paper beneath tiles is its ability to provide a moisture barrier. Tiles can crack or become damaged when exposed to water or moisture over time. Tar paper helps prevent water infiltration, protecting the underlying structure and ensuring the longevity of the tiles.
- Thermal Insulation: In addition to moisture protection, tar paper can also offer a certain level of thermal insulation. This helps in regulating the temperature and energy efficiency of the building.
- Soundproofing: Another advantage of using tar paper is its ability to reduce noise transmission. It acts as a sound barrier, preventing sound waves from passing through and creating a quieter environment.
Considerations for Tile Installations:
- Type of Tiles: While tar paper is a suitable option for many tile installations, it is important to consider the specific type of tile being used. Different types of tiles have varying moisture resistance properties. Porous materials, such as natural stone tiles, may require additional waterproofing measures, including a more advanced underlayment system.
- Substrate Condition: Before applying tar paper, it is crucial to ensure that the substrate, such as the concrete or wood surface beneath the tiles, is in good condition. Any existing moisture issues or structural problems should be addressed before installing the underlayment.
- Tile Adhesive Compatibility: Tar paper is compatible with most standard tile adhesives. However, it is essential to check the manufacturer’s guidelines and recommendations for compatibility before applying the adhesive over the tar paper.
Installation Process:
- Prepare the Substrate: Ensure that the substrate is clean, dry, and free from any debris or protrusions. Repair any cracks or structural issues as necessary.
- Roll out Tar Paper: Roll out the tar paper horizontally, starting at the bottom of the installation area. Overlap the seams by 4-6 inches to create a tight and secure moisture barrier.
- Attach the Tar Paper: Secure the tar paper to the substrate using staples, nails, or adhesive, ensuring a smooth and flat surface. Pay attention to perimeter edges and corners to provide complete coverage.
- Install Tiles: Once the tar paper is in place, the tile installation process can begin. Follow the manufacturer’s instructions for the specific type of tiles being used.
Tar paper can be applied beneath tiles to provide moisture protection, thermal insulation, and soundproofing benefits. It is a cost-effective solution that helps enhance the longevity of the tiles and the overall quality of the installation. However, it is important to consider the type of tiles, substrate condition, and compatibility with tile adhesives before deciding to use tar paper as an underlayment. Following the proper installation process ensures a successful outcome and a durable, moisture-resistant tiling system.
