Applying RV Liquid Roof Over Eternabond Seal Tape: A Step-by-Step Guide

Maintaining the integrity of your RV's roof seal is essential for both safety and comfort. This guide will explain how to apply RV Liquid Roof over an Eternabond seal tape, a common combination in RV roofing systems. Understanding the process ensures that the liquid coating provides a waterproof, airtight, and insulated seal. While the application requires some preparation, the results are well worth the effort.

What is Eternabond Seal Tape?

Eternabond seal tape is a durable, waterproof tape designed to seal and protect the edges of your RV's roof. It is often used to ensure a seamless and secure seal between metal components and rubber caps, playing a crucial role in maintaining the integrity of the roof. Eternabond seal tape is available in both 45 and 22 mil thicknesses, providing a robust solution for various weather conditions.

Why Apply RV Liquid Roof Over Eternabond Seal Tape?

Applying RV Liquid Roof over Eternabond seal tape can enhance the overall performance of your RV's roof. It offers several benefits:

Waterproof Seal: Liquid roofing offers a waterproof seal, ensuring that water does not penetrate the roof. Airtight Performance: It creates a seamless, airtight seal, which is crucial for maintaining the internal air pressure and insulation of the RV. Insulation: The coating provides excellent insulation, which can help regulate the temperature inside the RV and reduce energy consumption. Cost-Effective Solution: Despite the initial investment, the long-term benefits of liquid roofing make it a cost-effective solution compared to other options.

Steps to Apply RV Liquid Roof Over Eternabond Seal Tape

Applying RV Liquid Roof over Eternabond seal tape requires careful preparation and execution. Here are the detailed steps to follow:

Step 1: Clean and Pre-treat the Surface

Thoroughly clean the surface where you are applying the RV Liquid Roof. This includes removing any dirt, dust, or debris that could interfere with the adhesion of the coating. If necessary, use a degreaser to remove any oils or contaminants from the surface.

Step 2: Apply Contact Cement

First, apply a layer of contact cement to both the Eternabond seal tape and the surface where you are applying the liquid roof coating. Contact cement is a specialized adhesive that will help ensure the liquid roof adheres properly to the seal tape and the surface beneath.

Sub-step 2.1: Apply Contact Cement

Use a brush or roller to apply an even layer of contact cement to the Eternabond seal tape and the surface you plan to cover. Make sure you apply the cement evenly to ensure a strong bond.

Sub-step 2.2: Allow to Dry

Allow the contact cement to dry according to the manufacturer's instructions. This process typically takes about 5-10 minutes, depending on the type of cement and environmental conditions.

Step 3: Sand the Surface (Optional)

After the contact cement has dried, lightly sand the surface using a fine-grit sandpaper. This helps create a better surface for the liquid roofing to adhere to. Be careful not to sand too much, as this could remove the primer layer.

Step 4: Apply RV Liquid Roof

Once the surface is prepared, you can begin applying the RV Liquid Roof. Typically, this involves shaking the can to ensure the coating is mixed properly, then applying it using a paint roller or spray applicator.

Sub-step 4.1: Apply the Primer

Apply the primer layer on top of the contact cement. This layer is crucial for ensuring the proper adhesion of the final coating. Use a paint roller or sprayer to apply the primer evenly over the surface. Allow the primer to dry completely according to the manufacturer's instructions.

Sub-step 4.2: Apply the Liquid Roof Coating

After the primer has dried, you can apply the liquid roof coating. Apply the coating in several thin layers to ensure even coverage. Allow each layer to dry fully before applying the next, as indicated on the product label.

Step 5: Final Inspection and Finishing

Once the final layer of roof coating is dry, perform a final inspection to ensure that the seal is watertight and that there are no gaps or bubbles. If necessary, touch up any areas that need it. Allow the coating to cure fully before using your RV to ensure maximum effectiveness.

Benefits of Using RV Liquid Roof Over Eternabond Seal Tape

By following this process, you can enjoy several benefits:

Enhanced Water Resistance: The liquid roofing creates a waterproof seal, protecting your RV from water damage. Airtight and Insulated Roof: The airtight and highly insulated surface helps maintain a consistent and comfortable interior temperature. Cost-Effective Maintenance: Liquid roof coatings are generally more cost-effective in the long run compared to traditional roofing materials. Easy to Apply: The process is straightforward and can be done with basic tools, making it accessible for do-it-yourself enthusiasts. Long-term Durability: Liquid roofing can last for years with proper maintenance, providing long-term protection.

Conclusion

Applying RV Liquid Roof over Eternabond seal tape is a practical and effective solution for enhancing your RV's roof seal. By following the steps outlined in this guide, you can achieve a waterproof, airtight, and insulated roof that will protect your RV from the elements and ensure your comfort for years to come. However, it is always a good idea to consult with a professional if you are unsure about any aspect of the process or if you need assistance with the application.
