When you use the caulk on the RV exterior, you will be able to prevent leakage, cover the cracks, and you can easily improve the structural integrity of the RV as well.

You can do all of this and more only when you use the right type of caulk on the RV exterior.

The question is, which type of caulk is perfect for the RV exterior?

We will answer that below.

What type of caulk to use on RV exterior?
You can use silicone-based caulk as well as self-leveling caulk on the RV exterior.

We will go into the details of these types of caulk below. Once you go through the types and their details, it is easy to understand how to choose the best caulk for the RV exterior.

  1. Silicone-based caulk:
    One of the best types of caulk for the RV exterior is a silicone-based caulk.

The reason is that it works perfectly with nonporous surfaces. You will not have to worry about the material. As long as the surface is nonporous, it is compatible with it.

Additionally, this caulk is mold and mildew-resistant. That is why; you won’t have to worry about any organic growth. That is why it won’t deteriorate over a while.

The excellent durability of the silicon-based caulk means that there is no need to apply it again and again.

It has limited elasticity as well. That is why, even when you’re driving the RV on an uneven surface, you won’t have to worry about cracking of the caulk.

Due to all of these reasons, silicon-based caulk is the perfect option for the RV exterior.

  1. Self-leveling caulk:
    You have to keep in mind that you are dealing with the RV exterior. That is why whichever type of caulk you apply on the RV exterior, it will be visible. If the caulk is applied haphazardly, the RV exteriors will not look good enough. The caulk will stick out like a sore thumb.

You might think that this depends on the skill of the applicant.

This is, however, not true!

A much better approach is to opt for a self-leveling caulk. Even if a beginner uses the self-leveling caulk, the caulk will settle down smoothly after a while. It means that you will not have to worry about the haphazard application.

All you need to do is to let the caulk dry. Once the caulk dries, it will settle down on its own, and as the name suggests, it will level out as well. That is why you will no longer have to worry about improper levels or improper aesthetics.

You won’t have to hire a professional to apply the caulk at proper level either. That is why; you will be able to seal the RV exterior surface whenever you want.

Such caulks often consist of polyurethane material. It is only due to the polyurethane material that they have the self-leveling property.

So, you can use the silicone-based caulk and the self-leveling caulk when it comes to the RV exterior. Our guide above can help you understand why you should go with these caulks.
