Imagine yourself walking into a beautifully finished room, where the gleaming hardwood floor reflects the sunlight streaming through the windows. Beneath that elegant surface, what lies hidden? Is there a trusty layer of tar paper, or is it better left out? The answer, as with many construction questions, isn’t a simple yes or no. It’s a matter of understanding the role of tar paper, the potential benefits and drawbacks, and ultimately, your specific project’s needs.

Tar paper, a traditional underlayment material, has been a staple in construction for decades. But with advancements in building technology, the use of tar paper in contemporary flooring installations is a topic of debate. This guide delves into the complex world of tar paper under hardwood floors, exploring its history, modern alternatives, and the factors that determine its appropriateness for your project.
A Brief History of Tar Paper
Tar paper’s journey in construction is linked to the desire for a moisture-resistant barrier, a crucial element in protecting wood from decay and ensuring structural integrity. Its beginnings trace back to the 19th century when, as the name suggests, it was crafted by combining tar (a black, viscous substance obtained from wood or coal) with paper. This mixture created a relatively inexpensive and readily available material that could be easily applied to various surfaces, including roofs, walls, and floors.
The use of tar paper as an underlayment for hardwood floors gained popularity throughout the 20th century. Its primary function was to act as a moisture barrier between the subfloor and the wood flooring, preventing moisture from damaging the flooring. However, the advent of synthetic building materials, such as plastic sheeting and foam underlayment, offered more efficient solutions for moisture control and soundproofing. This paved the way for a shift away from tar paper, especially in modern construction projects.
Tar Paper vs. Modern Alternatives: The Pros & Cons
The decision of whether or not to use tar paper under your hardwood floor involves weighing its advantages and disadvantages against those of modern alternatives:
Tar Paper:

Pros:
- Cost-effectiveness: Tar paper remains relatively inexpensive compared to many modern alternatives, especially for larger projects.
- Traditional choice: It has been used for decades and is trusted by some for its effectiveness in preventing moisture damage.
Cons:
- Moisture barrier limitations: While tar paper provides a degree of moisture resistance, it isn’t waterproof and can degrade over time, allowing moisture to seep through.
- Limited sound absorption: Tar paper offers minimal soundproofing properties, making it a less desirable option for spaces requiring sound insulation.
- Installation challenges: Properly installing tar paper can be difficult, requiring careful overlapping and sealing, especially around areas that might experience moisture buildup.
- Environmental concerns: The production and disposal of tar paper can have environmental impacts, contributing to greenhouse gases and landfill waste.
Modern Alternatives:
Pros:
- Enhanced moisture control: Synthetic materials like plastic sheeting and moisture-resistant membrane offer superior moisture barrier properties.
- Superior sound insulation: Foam underlayment and other engineered materials provide excellent sound dampening capabilities.
- Ease of installation: Modern underlayments are typically easier to install, often requiring less specialized labor.
- Sustainability: Some modern materials are produced from recycled materials and are recyclable themselves, reducing environmental impact.
Cons:
- Higher cost: Modern underlayment materials generally cost more than tar paper, especially for larger projects.
When Might Tar Paper be a Suitable Choice?
While modern alternatives often offer advantages, there are specific situations where tar paper may still be appropriate:
- Budget-conscious projects: If budget is a primary concern, tar paper can be a cost-effective option for simple flooring installations. However, its limitations should be carefully considered.
- Traditional construction: In historical renovations or projects aiming for a traditional aesthetic, tar paper might be used to maintain the authenticity of the building. However, modern alternatives with similar performance characteristics might be used to retain the historical feel without sacrificing functionality.
- Limited moisture concerns: If the subfloor is relatively dry and the project has minimal moisture concerns, tar paper might suffice as a basic moisture barrier.
Factors to Consider When Making Your Decision
Choosing the right underlayment for your hardwood floor involves considering various factors:
- Subfloor type: The type of subfloor (e.g., concrete, plywood) can influence the appropriate underlayment. For example, concrete subfloors may require a different type of moisture barrier than plywood subfloors.
- Climate: The climate in your location affects moisture levels and the need for an effective moisture barrier. Humid climates typically require a more robust underlayment.
- Floor traffic: The amount of foot traffic the floor will experience can impact the choice of underlayment. High-traffic areas may benefit from a thicker and more resilient underlayment.
- Noise reduction: If soundproofing is a concern, choose an underlayment with good sound absorption properties.
Modern Alternatives: A Glimpse into the Future
Modern underlayment materials offer a range of solutions for different flooring needs. Here are some popular options:
- Plastic Sheeting: Plastic sheeting provides an effective moisture barrier and is relatively inexpensive. However, it lacks sound absorption and can be prone to tearing.
- Foam Underlayment: Foam underlayment offers excellent sound absorption and provides a comfortable cushion underfoot. It comes in various thicknesses and densities, allowing you to choose the right option for your project.
- Moisture-Resistant Membrane: Moisture-resistant membrane provides a more robust moisture barrier than plastic sheeting and is particularly suitable for areas with high humidity levels.
- Sound-Dampening Underlayment: This specialized underlayment is specifically designed to reduce noise transmission between floors.
Can You Use Tar Paper Under Hardwood Floor
Conclusion
Deciding whether or not to use tar paper under your hardwood floor depends on a multitude of factors. While tar paper offers a cost-effective solution for certain projects, modern alternatives often provide superior moisture control, sound absorption, and ease of installation. The key is to evaluate your specific needs and choose the underlayment that best balances performance, budget, and environmental considerations. By considering these factors and exploring modern underlayment options, you can ensure a robust and aesthetically pleasing hardwood floor that stands the test of time.
