They come in either a can of liquid sealant or as tape and can be applied to the roof and will protect your roof’s surface and the paint.

How to install RV sealant

Also check if your roof needs to be primed before applying sealant. Here is a tutorial on installing sealant from DIY Outdoor Life on Youtube.

What is the difference between RV coating and sealant?

RV coating and sealant are very similar and they often get mixed up, but there are a few key differences to be aware of. According to Silver Spur RV Park, “RV roof coatings are generally used to cover the entire roof, while “sealants” are sometimes used to patch up specific cracks, leaks, or damaged areas of the roof. However, the terms coating and sealant are often used interchangeably”.
