Dicor 501LSW-1 Epdm Self-Leveling Lap Sealant
- Creates a secure, secondary seal along the roof’s edges, air vents, vent pipes and screw heads
Dicor 501LSW-1 is by far one of the Best RV Caulks for RV exteriors. This is Amazon’s best-seller in industrial sealants. It is better known as Dicor lap sealer because this putty rotates rather than hardens completely. Note that “spinning” does not mean it is liquid. In fact, it is quite a thick putty. Due to this feature, Dicor Lap Sealant is best used for RV roofing, which is the largest structure that requires waterproofing.
First of all, this RV caulk is waterproof, which means that it can prevent leakage and can stay sturdy even when rain falls on it. It also has a very strong adhesion, which makes it very sticky and capable of holding almost any material. It can hold up well on aluminum, fiberglass, wood, vinyl, and even concrete. In addition to the grip, it is also very flexible and capable of sealing cracks and holes.
This putty also offers a certain level of versatility, as it is effective in many parts of your RV. You can use it to seal your roof, vents, pipes, RV trim, screws, windows, etc. And it offers high-quality performance when used in all of these areas. Also, it doesn’t fade over time, which is often a big problem for many RV putties. Instead, this product will blend into the color of the material and ensure that you don’t end up with that terrible yellow cast that most sealers leave behind.
One of the best features of this RV putty is that it works with all types of ceilings. It is also stabilized against UV rays and treated so that it does not deteriorate or discolor after application. Another advantage for you and your RV is that the putty also comes in a reasonably priced kit of four. You can stock up and not have to worry about ordering more soon. Since it is compatible with various RV materials, it can also be used in various parts of your RV. Obviously, it is very good at sealing the ceiling, especially around the edges. Other than that, I find this one to be very good for cracks and holes in air vents, pipes, screws, RV edges, and many other sealing parts as well. It is also a very good window sealer.
Using caulk to seal the edges of your RV’s roof, vents, ventilation system, and air conditioning can help you avoid spending a lot of money on repairs. The caulk also prevents water from entering the RV and air from escaping outside. Dicor No-Sag Sealant is UV stabilized and will not discolor or fade over time. This means that it does not stain or discolor the surface on which it is applied. Caulking is ideal for use where self-leveling is not needed, such as on vertical surfaces. It is compatible with all roofing materials and offers excellent adhesion to wood, aluminum, vinyl, galvanized metal, concrete and mortar. It does not contain any harmful air pollutants and permanently seals and remains flexible for many years.
3M Marine Adhesive Sealant for RV
- USE WHAT THE PROS USE – Extremely strong adhesive sealant retains strength above or below waterline
If you’re looking for the best RV caulk, 3M Marine Fast Cure Adhesive / Sealant might be the product for you. This sealant has been designed to provide a tight seal between joints bonded to fiberglass material.

It is ideal for fastening, gluing and sealing interior parts of boats and RVs.

As you move from one location to another in your RV, the sealant stays in place and won’t crack or peel off. Maintains a strong bond even when your vehicle is vibrating or moving fast. You can apply this sealer with a manual caulking gun and it will stay usable for up to four hours.
As the name suggests, this is a 3M marine adhesive sealant, which means it is marine grade. It shows that he is really strong and tough. When you apply it to a crack, you can expect it to have a permanent bond. Another cool thing about this product is that it doesn’t take long before it sticks. For most sealers, it would take a few days for it to really adhere and solidify. This takes a maximum of 2 days to do. When it solidifies, it really bonds the material. Even during storms, earthquakes, and other weather conditions, this sealant can remain strong and maintain adhesion. The link also lasts for years, making it one of the best maintenance tools to have in your arsenal.
By providing a flexible and durable elastomeric bond, this sealant resists the vibration, swelling and shrinkage experienced by the exterior of your RV. This prevents your sealant from being damaged by UV rays, temperature fluctuations and inclement weather, as well as life on the road in general. For an excellent waterproof seal that is highly resistant to UV rays, it is difficult to find a better product. With its firm rubber seal and high durability, this sealant is a good choice for most RV exteriors, resistant to vibration, traffic, and weather. However, it costs a bit more than many other versions.
