Overview of Eternabond RoofSeal
Eternabond RoofSeal is a cold-applied, fiberglass-reinforced adhesive tape that creates a permanent waterproof seal on a wide range of roofing materials. It is designed to expand and contract with the roof surface in response to temperature and environmental changes, maintaining its integrity over time. The tape is available in various widths and lengths, with 4" x 50' and 6" x 50' being the most common sizes for residential and light commercial applications.
One of the key advantages of Eternabond RoofSeal is its ease of installation. It requires minimal surface preparation and can be applied directly over existing sealant, provided it is clean and free of debris. The adhesive backing forms a molecular bond with the surface, creating a durable, flexible seal that resists UV exposure, weathering, and mechanical stress.
Eternabond RoofSeal is suitable for sealing seams, vents, skylights, HVAC units, gutters, and other roof features. It is particularly well-suited for use on rubber roofs (EPDM and TPO), metal roofs, and composite roofing materials. Once applied, it forms a waterproof barrier that prevents water infiltration, reducing the risk of leaks, mold, and structural damage.
Tools and Materials Required for Installation
Before beginning the installation of Eternabond RoofSeal, it is important to gather the necessary tools and materials. A well-prepared toolkit ensures a smooth and efficient installation process and helps to avoid common mistakes that can compromise the effectiveness of the seal.
The essential tools and materials for Eternabond RoofSeal installation include:
- Eternabond RoofSeal Tape: Available in various widths and lengths, choose the appropriate size based on the dimensions of the area to be sealed.
- Cleaning Supplies: A dry rag, a damp rag, and acetone or an Eternabond-approved cleaning solution for surface preparation.
- Stainless Steel Roller (2" Width): Used to activate the adhesive and press the tape into place, ensuring strong adhesion and eliminating air pockets.
- Utility Knife or Sharp Scissors: For cutting the tape to the desired size and shape. Avoid using box cutters unless absolutely necessary, as they pose a risk of damaging the roof surface.
- Razor Blade or Gasket Scraper: For removing old sealant if necessary.
- Additional Rags: For wiping the surface and removing excess cleaning solution or debris.
It is also recommended to have a small roller for pressing the edges and ends of the tape after installation to ensure a complete and durable seal. Having all the necessary tools on hand before starting the installation helps to streamline the process and avoid unnecessary delays.
Surface Preparation and Cleaning
Proper surface preparation is one of the most critical steps in the Eternabond RoofSeal installation process. A clean, dry, and debris-free surface ensures optimal adhesion and long-term performance of the tape. The following steps should be followed to prepare the surface:
Remove Debris and Loose Material: Use a dry rag to wipe away any loose particles, dust, or dirt from the area. This step is essential for ensuring that the tape adheres directly to the roof surface without any interference.
Wipe with a Damp Rag: After removing loose debris, use a damp rag to clean the surface of any dirt or grime. Allow the surface to dry completely before proceeding to the next step. This helps to ensure that the cleaning solution applied in the following step will work effectively.
Apply Cleaning Solution: Use a clean rag dipped in acetone or an Eternabond-approved cleaning solution to thoroughly clean the area where the tape will be applied. It is important to apply the cleaning solution using the rag rather than pouring it directly onto the surface. This prevents oversaturation and ensures that the solution is applied evenly.
Allow the Surface to Dry: After cleaning, allow the surface to dry for at least 30 minutes. This step is crucial, as any residual moisture can interfere with the adhesive bonding process and reduce the effectiveness of the seal.
Test Adhesion on Metal Surfaces: If applying Eternabond RoofSeal to a metal roof, it is recommended to perform a small test application to confirm that the tape adheres properly to the specific type of metal being used. Metal surfaces must be free of oils, coatings, and oxidation to ensure a strong bond.
It is also important to note that Eternabond RoofSeal can be applied directly over old lap sealant or RainKap, provided the existing material is clean and intact. However, if the old sealant is cracked or deteriorated, it may be necessary to remove it before applying the new tape to ensure a strong and effective bond.
Applying Eternabond RoofSeal
Once the surface has been properly cleaned and dried, the next step is to apply the Eternabond RoofSeal tape. The application process should be done carefully and methodically to ensure that the tape adheres properly and forms a watertight seal.
Peel the Release Liner: Begin by peeling back the release liner from the adhesive side of the Eternabond tape by about 10 inches. This allows the tape to be positioned without it sticking prematurely to the surface or to itself.
Position the Tape: Press the end of the tape into place at the desired location on the roof. It is important to start the application at one end and work gradually along the length of the tape. Avoid attempting to remove the entire release liner at once, as this can make it difficult to control the placement of the tape and may result in misalignment.
Apply the Tape in Sections: Work in sections of approximately 12 to 24 inches, peeling back the release liner as you go. This method helps to maintain control over the tape and ensures that it is applied evenly and without wrinkles or air pockets.
Use Firm Pressure: As the tape is applied, use firm pressure with your hand or a seam roller to press it into place. This helps to eliminate air pockets and ensures that the adhesive makes full contact with the surface. It is important to apply continuous pressure along the entire length of the tape to create a strong and durable bond.
Smooth Out Bubbles or Tents: If a bubble or "tent" forms during the application, it should be addressed immediately. Use a pin to lance the bubble and then roll the area again with the roller to allow the adhesive to reseal the pinhole. If a tent forms, cut the tent and fold the sides over one at a time, then press a small piece of Eternabond over the area and roll it firmly with the roller to ensure a secure seal.
Round the Corners: To prevent the corners of the tape from peeling up over time, it is recommended to round them slightly before pressing the tape into place. This helps to reduce stress on the edges and improves the overall durability of the seal.
Apply Continuous Pressure: After the tape has been positioned and the release liner has been fully removed, apply continuous pressure along the entire length of the tape. This step is crucial for ensuring that the adhesive is activated and that the tape adheres fully to the surface.
Finish Sealing the Edges and Ends: Finally, apply additional firm pressure around the edges and ends of the tape to ensure that the seal is complete and secure. This step helps to prevent water from seeping underneath the tape and ensures that the seal remains intact over time.
Post-Installation Care and Considerations
After the Eternabond RoofSeal has been applied and properly pressed into place, it is important to consider a few additional factors to ensure the long-term effectiveness of the seal.
Immediate Effectiveness: The seal formed by Eternabond RoofSeal is effective immediately after installation. This means that the tape can withstand exposure to water and other environmental factors without compromising the integrity of the seal. However, the adhesion will continue to strengthen over time, so it is important to avoid subjecting the tape to excessive stress or mechanical pressure immediately after installation.
Avoid Overlapping or Stacking: It is generally not recommended to overlap or stack multiple layers of Eternabond RoofSeal, as this can create an uneven surface and reduce the effectiveness of the seal. If additional reinforcement is required, it is better to apply the tape in a single, continuous layer.
Avoiding Obstruction of Roof Features: When applying Eternabond RoofSeal near roof features such as awnings, vents, or skylights, care should be taken to ensure that the tape does not interfere with the operation of these components. The tape should be applied in a way that allows for the normal movement and function of the feature without compromising the seal.
Storage and Handling of Excess Tape: If there is any excess Eternabond tape that is not used during the installation, it should be stored in a cool, dry place away from direct sunlight. The adhesive backing can degrade over time if exposed to heat or moisture, so proper storage is essential for maintaining the quality and effectiveness of the tape.
Inspection and Maintenance: While Eternabond RoofSeal is designed to be a long-lasting and durable solution, it is still important to periodically inspect the seal for signs of wear, damage, or deterioration. If any issues are identified, the affected area can be repaired by applying a small piece of new Eternabond tape over the damaged section and pressing it firmly into place with a roller.
Weather Considerations: Eternabond RoofSeal is designed to withstand a wide range of weather conditions, including UV exposure, temperature fluctuations, and moisture. However, it is still important to apply the tape in a dry environment and to avoid working on the roof during periods of high humidity or rain. This helps to ensure that the adhesive is activated properly and that the bond remains strong and effective.
Performance and Durability of Eternabond RoofSeal
Eternabond RoofSeal is engineered to provide a long-lasting, durable seal that can withstand the rigors of outdoor environments. The tape is designed to expand and contract with the roof surface in response to temperature and humidity changes, maintaining its integrity over time. This flexibility helps to prevent the tape from cracking, shrinking, or peeling, which are common issues with lower-quality sealants.
One of the key features of Eternabond RoofSeal is its ability to form a molecular bond with the surface it is applied to. This type of bond is much stronger and more durable than standard adhesive bonds, as it creates a seamless connection between the tape and the roof material. Independent laboratory testing has shown that Eternabond RoofSeal can prevent water penetration even under high-pressure conditions, making it an excellent choice for sealing and repairing roof surfaces.
In addition to its waterproof properties, Eternabond RoofSeal also offers excellent UV resistance, which helps to prevent degradation from prolonged exposure to sunlight. This is particularly important for roofs that are exposed to direct sunlight for extended periods of time, as UV radiation can cause many types of sealants to break down and lose their effectiveness.
The durability of Eternabond RoofSeal is further enhanced by its high elongation factor, which allows the tape to stretch and flex without losing its adhesive properties. This makes it well-suited for use on roofs that experience frequent expansion and contraction due to temperature changes. The tape is also resistant to mechanical stress, making it less likely to tear or break when subjected to normal wear and tear.
