Top 5 Best RV Adhesives and Sealants to Use in 2021


Every RV owner wants to keep their vehicle in the proper condition and high performance. However, daily usage comes with exposure to harmful elements which may dent the roof, leading to leaks from rain. The costs that result from water damage are a real pain that no one wants to experience. That’s why adhesives and sealants are here to help RV owners enjoy top service from their vehicles. This article lists top-ranking products and why they are so important.

Why are RV adhesives and sealants necessary?

RV adhesives and sealants are must-have products for every owner. Their value is indispensable. If used early enough, adhesives can save the owners from substantial repair costs and lengthen their vehicle’s lifespan. Here are the top reasons why they are a great asset.

  • Sealants provide insulation from harsh external elements, hence offering structural protection to the vehicle.
  • Sealants act as insulation in the warm summer weather and cold winters, cutting down on air conditioning and energy costs inside the vehicle.
  • Sealing tiny holes could save the RV owner from huge repairing costs if the damage extends.
  • They reduce the need for regular roof maintenance.
  • Caulking around windows and trim helps in keeping external elements from accessing the vehicle.

Top five Adhesives and sealants

When shopping for high-quality RV sealant and adhesive products, it pays to look from brands that have built a name for top performance and efficacy. RV owners can trust some of the best brands for high-quality adhesives, including GE Sealants and Adhesives, DAP products, and Gorilla Touch. Dicor Products and Liquid Rubber are also some of the big names when it comes to RV sealants. Here are some of the best products.

  1. M Marine Adhesive Sealant

RV roofs suffer the worst beating from external elements and UV rays. As a result, they’re the most common parts that require frequent repair from the owners. In case of a leak, M Marine is a superior product that offers the best services. The adhesive is a product of a rigid polyurethane polymer to withstand weathering. It also doesn’t peel off or crack due to shocks and vibrations.

M Marine Adhesive Sealant is durable and extremely strong, making it suitable for boats and jet skis. However, it takes relatively long to dry up and isn’t ideal for use in extreme heat conditions (which makes it thin).

  1. Heng’s Rubber Roof Coating

This product is a favorite to many RV owners due to its quality, ease of use, and efficiency. It comes in a superior formulation that makes it an ideal solution for cracks, tears and generally boosting RV roofs’ integrity. It’s eco-friendly, flexible, and protects the roof against harsh UV rays.

The only downside is that it’s a typical acrylic formulation; hence it doesn’t last long compared to a silicone product.

  1. Flex Seal Liquid Rubber in a Can

For an RV owner looking to have a powerful sealant to use on the vehicle and round the house, this is a true multi-purpose giant. Its extra-smooth formulation makes it easy to use and also offers UV protection to the RV roofs. The product also insulates the roof from rust, corrosion, and other harmful chemicals. It’s multi-purpose and can serve different functions around the house.

The only disadvantage is that it’s thinner, hence needs at least three coats to reach its full potential. This factor could make it a bit pricey.

  1. Geocel Proflex RV Sealant

Here is an excellent value for RV owners looking to resell their vehicles after applying sealant. The product offers a nice-looking finish, can work on various types of materials and surfaces, and allows for painting after the process. It’s also highly flexible and seals leaks and cracks after a single application. The only setback is that it’s relatively expensive.

  1. Dicor EPDM Self-Leveling Sealant

This Dicor product is one of the top-sellers in the world of motorhome enthusiasts. It is ideal for covering screw heads, sealing vents, and fixing cracks in the roofs. It’s compatible with TPO, and EPDM sheeting blends perfectly with various RV roof types, easy to apply, and self-levels. The sealant adheres to different materials and surfaces. However, it comes in a small tube which may mean a significant investment to seal an RV fully.

Roof coatings are essential assets to RV owners since they have the power to lengthen the lifespan of the vehicle and cut down on major expenses. Similarly, their application is one of the most straightforward do-it-yourself tasks that doesn’t cost much. However, it’s essential to follow the proper preparation guidelines and take necessary precautions to enjoy the most out of the process.
