Winter is almost here, and for many of us the cold weather has arrived and looks like it’s here to stay. If your roof is not yet covered with a blanket of snow, now is the perfect time to seal up any areas where leaks may be present. Keeping moisture out of your home or RV will prevent unwanted damage, mold, and costly repairs.
There are several different versions of 4EvaSeal® waterproofing tape. Each is designed for a specific use or uses. So, how do you choose the right one for your application? Let’s review the product line and break down the materials that form each product to better understand how and where each version of 4EvaSeal® can be used.
Self-adhesive waterproof tapes bond to substrates with greater force when the substrates are clean and dry and the tapes are applied in warm temperatures. The greatest challenge with existing materials is always how to get them clean. Outdoor substrates collect dirt that can become embedded in the surfaces. The surfaces can also be dusty or chalky from UV exposure.
Reinforcing fabrics are regularly used with roofing, coating and waterproofing systems. They are necessary to properly detail certain conditions. However, they require extra labor and materials to install.
Reinforcing serves several purposes:
- It strengthens the roofing, coating or waterproofing over joints, seams, etc.
- It assures proper film thickness for liquid-applied materials.
- It assists in bridging gaps between materials.
Single-ply roof membranes are plastic or rubber roofing materials that consist of one thin layer of material. The most common types of single-ply roof membranes are EPDM rubber roof membranes, PVC roof membranes, and TPO roof membranes. These roofs can vary in thickness from 40 mils to 80 mils (1/16” +/-).
Recreational Vehicle (RV) roofs have to endure weather conditions of every other type of roof but also need to handle 70 mph winds on the highway. The roof will flex and twist as the RV is in motion and endure the occasional low hanging branch at a campground. Damage can happen and, when it does, a permanent waterproofing repair tape is often the best solution.

Part 1 of this 2-part series we discussed the importance of inspection, cleaning, and profiling.
The final step to surface preparation, and most often overlooked is environmental monitoring.
It is important to understand the environmental limitations of self-adhesive materials and to ensure that the application of these materials is performed within their limitations for a successful application.
The limitations of these products are typically found on product data sheets. Always contact the manufacturer if the product data sheet does not contain information on how temperatures and humidity can affect the application of the product intended for use.
Peel-and-Stick seal and waterproof tapes are commonly used to prevent water from intruding into structures such as homes, commercial buildings, and recreational vehicles. These tapes provide outstanding long-term and life time performance when used properly. Proper use of tapes refers to not only the service environment but also how the tapes have been applied to details of complex shapes and penetrations and, most importantly, how well the surface has been prepared for application.
