The best way to keep your recreational vehicle (RV) in good condition is to ensure that it is routinely maintained.
It would be nice if they were built similarly to the exteriors of waterproofed buses, but that would make RVs much more expensive. Thankfully, an RV waterproof sealant can significantly protect your trailer from the elements.
If you are in the market for the best RV sealant Dallas, TX, then you’ve come to the right place. Below, we discuss the best RV exterior sealant options in the market.

Frequently Asked Questions about RV Roof Caulking
At Coach Specialists, we often get asked about RV roof caulking. Here are our top three most popular customer queries:
Why can’t I use the regular caulk for my kitchen sink?
The problem with using just regular household caulks is that they are usually silicone-based. This type of caulk is the most common and is used chiefly for kitchens and bathrooms. Unfortunately, RV silicone caulking is terrible to use on RVs because they can’t withstand the harsh climates and environments out on the road. In addition, silicone caulks are also much harder to remove. This makes it more tedious to repair campers that use an RV silicone sealant.
Can I use the sealant through the entire RV?
Most sealants are suitable for multiple surfaces, but not all. For example, the RV caulk sealant used on roofs, windows, walls and A/C cutouts requires waterproofing.
How expensive are RV sealants?
Not all RV sealants are created equal, which means they don’t cost the same. But don’t worry, they’re not too expensive. After a quick search online, you’ll find many RV roofing caulk options at discounted prices.
However, one thing that can raise the cost of sealants is going the DIY route. Not everyone knows how to properly seal seams which means the caulk needs to be reapplied multiple times, resulting in additional purchases of RV roof caulking. You’ll most likely end up spending more money than you have to!
Our RV Sealant Top Picks
Geocel 28100V ProFlex RV
The most well-known RV sealant is the Geocel 28100V Proflex – more commonly known as just Proflex. You can find it in clear, white, black, almond or bright finishes. Proflex works great on horizontal structures such as roofs and verticals like windows. In addition, it works well in withstanding different environments and temperature changes that RVs often experience. You can buy this for around $10 to $15.

The Dicor 501LSW – 1 Lap Sealant is one of the best caulk for RV exterior, especially on roofs. Amazon has rated it a top seller among similar products. We love this product as it has a very thick consistency and will not harden immediately. Instead, it remains flexible, hence the “lap” in its name. You can typically find this product for sale at around $10 to $15.

Tremco Vulkem 116 Caulk
Tremco made our list as it is a very affordable product. It is an economical option when planning to buy multiple containers.

It’s also a very versatile product. Amazon currently lists this product on sale for $8 or less.

It can also stick to many different materials like concrete, wood, plastic, asphalt and metal. It is very flexible with no risk of freezing either. For these reasons, we consider this brand as one of the best RV sealant Dallas, TX. Sashco can be found on Amazon for around $10.

How To Properly Use an RV Roof Repair Sealant?
As mentioned above, going the DIY route is not ideal. However, If you still choose to self-seal your RV, we recommend buying containers in bulk in case there is a mishap. It would help if you also use caution when starting the process. Since many of these caulks don’t work well with certain materials, it’s best to map out where the product needs to go before starting the project. Make sure everything is cleaned and dried before application as well. Finally, only cut off small holes in the tips as some of the products can be challenging to control.
