Before diving into the pros and cons of using tar paper under laminate flooring, it is essential to understand its purpose and characteristics. Tar paper, also known as roofing felt, is a thin, asphalt-saturated paper commonly used for waterproofing and moisture control in roofing applications. Its primary function is to prevent water from penetrating the roofing material. However, its use beneath laminate flooring raises some concerns, as we will explore in detail.

Understanding the Role of Underlayment

Before we address the specific issue of tar paper, let’s first understand the crucial role of underlayment in laminate flooring installation. Underlayment is a fundamental component of any laminate flooring project, serving several essential functions:

1. Moisture Protection

One of the primary roles of underlayment is to act as a barrier against moisture. This is critical because laminate flooring is susceptible to damage from water, which can lead to warping, swelling, and delamination. By creating a moisture-resistant layer, underlayment protects your flooring from potential sources of water intrusion, such as spills, leaks, or high humidity.

2. Sound Dampening

Laminate flooring, while durable, can be relatively noisy. Underlayment helps to mitigate this by providing sound insulation. It creates a cushioning layer that absorbs sound, reducing footfall noise and creating a quieter environment. This is especially beneficial in multi-level homes or apartments where noise transfer can be a concern.

3. Subfloor Leveling

No subfloor is perfectly smooth, and even minor imperfections can make laminate flooring feel uneven and unstable. Underlayment can help to level out minor subfloor irregularities, creating a more even surface for your flooring. This can improve the overall appearance and stability of the laminate.

4. Added Cushioning

Underlayment can contribute to greater comfort underfoot. By providing a cushioned layer, it reduces the hardness of the laminate flooring, making it feel softer and more comfortable to walk on.

Tar Paper as an Underlayment: Pros and Cons

Now, let’s focus on the specific issue of tar paper as an underlayment for laminate flooring. While tar paper is a cost-effective material and readily available, it has several drawbacks that may make it unsuitable for this application. To make an informed decision, consider these pros and cons.

Pros of Using Tar Paper

While the list of advantages is limited, here are some potential benefits of using tar paper:

• Cost-effective: Tar paper is generally an inexpensive material compared to specialized underlayment options. This can be a significant factor in budget-conscious projects.
• Moisture Resistance: Tar paper, being asphalt-saturated, provides some degree of moisture resistance, though not as effective as dedicated underlayment products.

Cons of Using Tar Paper

The drawbacks of using tar paper as an underlayment outweigh its potential advantages:

• Limited Moisture Barrier: Tar paper’s moisture resistance is not as reliable as specialized underlayments designed for laminate flooring. It may not prevent the penetration of water vapor and could compromise the structural integrity of the flooring.
• Poor Sound Insulation: Tar paper does not provide effective sound dampening. You may not experience the noise reduction benefits offered by other underlayments.
• Difficult Installation: Tar paper can be difficult to install properly, especially in large areas. It can wrinkle, tear, or create uneven surfaces, affecting the overall appearance and performance of the laminate flooring.
• Potential VOCs: Tar paper can release volatile organic compounds (VOCs) into the air, particularly during installation. While these emissions are typically low, it’s essential to ensure adequate ventilation during and after installing tar paper.
• Not Recommended by Manufacturers: Most laminate flooring manufacturers specifically advise against using tar paper as an underlayment. They often cite concerns about moisture resistance, sound dampening, and compatibility with their flooring products.

The Importance of Manufacturer Recommendations

It is crucial to consult the manufacturer’s recommendations for your specific laminate flooring product. They often provide detailed guidelines on suitable underlayment options and installation procedures. Ignoring these recommendations may void your warranty and compromise the longevity and performance of your flooring.

For instance, the manufacturer may recommend using an underlayment with specific moisture resistance ratings, sound reduction values, or even specific material compositions. These recommendations are based on rigorous testing and ensure compatibility and optimal performance with their flooring products.

Alternative Underlayment Options for Laminate Flooring

If you choose not to use tar paper, there are numerous underlayment options specifically designed for laminate flooring, each offering unique benefits. Consider the following:

1. Foam Underlayment

Foam underlayment is a popular choice for laminate flooring. It is typically made of polyethylene foam with a moisture-resistant layer. It offers excellent sound reduction capabilities, cushioning, and a smoother surface for the laminate. These underlayments are also relatively easy to install and come in different thicknesses to address various subfloor conditions.

2. Cork Underlayment

Cork underlayment is another excellent option, known for its durability, moisture resistance, and sound insulation properties. Cork is a natural material that provides a unique warmth underfoot, improving overall comfort. It also offers good resilience and can effectively minimize footfall noise.

3. Rubber Underlayment

Rubber underlayment is particularly beneficial for reducing noise and providing a resilient cushioning layer. It is excellent in applications where impact noise is a concern, such as multi-story homes or apartments. Rubber underlayment is also relatively durable and resistant to moisture.

4. Composite Underlayment

Composite underlayment combines different materials, such as foam, rubber, and moisture-resistant barriers, to provide a multi-functional solution. These products offer excellent moisture protection, noise reduction, and cushioning, making them a comprehensive underlayment option.

Choosing the Right Underlayment for Your Needs

The best underlayment for your laminate flooring project depends on several factors, including:

• Subfloor Condition: If your subfloor is uneven or requires leveling, consider an underlayment with a thicker construction.
• Noise Reduction Requirements: If sound reduction is a top priority, opt for an underlayment with high sound reduction values.
• Moisture Protection Needs: If your project involves a high risk of moisture intrusion, select an underlayment with robust moisture resistance properties.
• Budget: Underlayments vary in price, so choose a product that fits your budget while meeting your functional requirements.

Installation Tips for Underlayment

Once you have chosen an appropriate underlayment for your laminate flooring, proper installation is essential for optimal performance. Here are some general tips:

• Clean Subfloor: Before laying down underlayment, ensure your subfloor is clean, dry, and free of debris. Any dirt or roughness can affect the smoothness and adhesion of the underlayment.
• Overlap Seams: When overlapping seams, ensure they are at least 4 inches to prevent moisture penetration. This allows for a more effective moisture barrier.
• Secure Edges: Secure the edges of the underlayment with staples or tape to ensure a snug fit and minimize movement. This prevents the underlayment from bunching up or lifting during installation.
• Follow Manufacturer Instructions: Always follow the specific installation instructions provided by the underlayment manufacturer. This will ensure correct installation practices and optimal performance.
