Overview of Dekorman Underlayment Products
Dekorman offers a range of underlayment solutions tailored for different flooring types and subfloor conditions. Two primary products are highlighted in the source material: Dekorman Unibase and Dekorman Laminate Flooring White Foam Underlayment. These products differ in thickness, coverage, and installation methods, and they are designed to meet the unique demands of modern flooring systems.
Dekorman Unibase
Dekorman Unibase is an 8mm thick underlayment designed for use in moisture-prone areas such as basements. It is composed of closed-cell IXPE foam, which provides a waterproof and vapor-resistant barrier. This product is free from VOCs, making it an environmentally safe option for indoor use.

The coverage is 100 square feet per roll, and the product has a density of 800 kg/m³, ensuring long-lasting durability.
Dekorman Laminate Flooring White Foam Underlayment
This product is a 2mm thick foam underlayment suitable for vinyl plank, bamboo, floating laminate, and engineered wood flooring. It provides cushioning and sound absorption, with an IIC rating of 68 and an STC rating of 65. The underlayment is constructed from closed-cell foam, which offers protection against moisture, mold, and mildew. It also includes self-adhesive tape for ease of installation and covers up to 300 square feet, depending on the package selected.
Both underlayment options are engineered to provide comfort, sound insulation, and environmental protection, making them suitable for a wide range of flooring projects. However, their application methods and compatibility with different flooring types vary, and these differences must be considered during the installation process.
Installation Procedures for Dekorman Underlayment
Proper installation is critical for the performance and longevity of any underlayment. While each product has its own set of instructions, general best practices and manufacturer-specific guidelines should be followed to ensure a successful installation.
Preparing the Subfloor
Before laying the underlayment, the subfloor must be prepared according to the manufacturer’s specifications. The subfloor should be clean, dry, and free of debris. For concrete subfloors, a moisture test should be conducted to determine if a vapor barrier is necessary. If the subfloor is uneven or has minor imperfections, the underlayment can help to level the surface, but any major irregularities should be addressed with a leveling compound before installation.
For Dekorman Unibase, the underlayment is designed to smooth out minor subfloor imperfections through its dimpled surface and poly-shim technology. However, for significant unevenness, additional leveling may be required. The underlayment should be unrolled across the entire floor area, ensuring that the seams are overlapped and sealed with the provided sealing tape. The manufacturer recommends that the underlayment be cut to fit the room dimensions and that any rips or perforations in the vapor barrier be repaired before proceeding with flooring installation.
For the Dekorman Laminate Flooring White Foam Underlayment, the installation process is similar but with a few key differences. This product is designed for use with self-adhesive tape, which is included with the underlayment. The underlayment should be laid from wall to wall, with seams aligned and secured using the adhesive tape. It is important to ensure that the underlayment lies flat and that there are no gaps between pieces. If the underlayment is difficult to lay flat, additional adhesive may be required to secure it in place.
Laying the Underlayment
Both products require careful attention to the direction in which the underlayment is laid. For Dekorman Unibase, the manufacturer recommends that the seams run perpendicular to the flooring seams to ensure optimal performance. This helps to prevent any potential issues with expansion or contraction of the flooring materials.
For the Dekorman Laminate Flooring White Foam Underlayment, the same principle applies. The underlayment should be laid in a direction that complements the natural expansion and contraction of the flooring material. In some cases, the underlayment may be used in conjunction with flooring that already has an attached pad, but it is important to follow the manufacturer’s guidelines to avoid over-adding layers, which can affect the performance and durability of the flooring.
Sealing and Final Checks
After the underlayment is laid, it should be inspected for any gaps, rips, or perforations in the vapor barrier. These should be sealed using the provided sealing tape or additional adhesive if necessary. The underlayment should also be tested for flatness, and any areas that are not lying flush with the subfloor should be adjusted. Once the underlayment is properly installed, the flooring can be laid on top according to the manufacturer’s instructions.
Key Features and Performance Metrics
Dekorman underlayment products are engineered with a variety of features that enhance their performance and usability in different environments.
Moisture and Mold Resistance
Both underlayment options are designed with closed-cell foam structures that provide resistance to moisture, mold, and mildew. This is particularly important for subfloors that are prone to moisture issues, such as concrete or basement floors. The vapor barrier in both products prevents the buildup of moisture beneath the flooring, which can lead to warping, buckling, or other damage over time.
Sound Insulation
Sound insulation is a key consideration for flooring installed in multi-level homes or apartments. Dekorman underlayment products offer sound absorption and insulation through their foam construction. The Dekorman Laminate Flooring White Foam Underlayment has an IIC rating of 68 and an STC rating of 65, making it effective for reducing impact and airborne noise transmission. The Unibase product also provides sound insulation through its poly-shim technology and thick IXPE foam, though specific ratings are not provided in the source material.
Comfort and Durability
The thickness and density of the underlayment play a role in the overall comfort and durability of the flooring system. Dekorman Unibase, at 8mm thick and with a density of 800 kg/m³, provides a higher level of cushioning and support compared to the 2mm thick Laminate Flooring White Foam Underlayment. This makes it particularly suitable for areas where comfort and durability are priorities, such as living rooms, bedrooms, or high-traffic areas.
Compatibility with Flooring Types
Dekorman underlayment products are compatible with a variety of flooring types, including vinyl plank, laminate, engineered hardwood, and carpet. The Unibase product is specifically designed for use with vinyl plank, laminate, and engineered hardwood flooring, and it can also be used with carpet in certain applications. The Laminate Flooring White Foam Underlayment is suitable for vinyl plank, bamboo, floating laminate, and engineered wood flooring.
Considerations for Optimal Performance
When selecting and installing Dekorman underlayment, several factors should be considered to ensure optimal performance and longevity.
Subfloor Condition
The condition of the subfloor is one of the most important factors in determining the success of the underlayment installation. Any major imperfections or irregularities in the subfloor should be addressed before laying the underlayment. For concrete subfloors, a moisture test should be conducted, and a vapor barrier should be used if necessary. In cases where the subfloor is rough or uneven, a leveling compound may be required to bring it up to specifications.
Environmental Conditions
Environmental factors such as humidity and temperature can affect the performance of the underlayment and the flooring system. It is important to install the underlayment in a dry, stable environment to prevent issues such as warping, buckling, or mold growth. The underlayment should also be allowed to acclimate to the room conditions before installation.
Manufacturer Recommendations
Following the manufacturer’s recommendations is essential for achieving the best results with Dekorman underlayment. This includes using the correct installation methods, sealing the seams, and ensuring that the underlayment is properly secured. It is also important to avoid using multiple layers of underlayment unless specifically recommended by the manufacturer, as this can affect the performance and durability of the flooring system.
Conclusion
Dekorman underlayment products offer a range of features and benefits that make them suitable for a variety of flooring applications. From moisture resistance and sound insulation to durability and comfort, these products are designed to enhance the performance and longevity of modern flooring systems.
