Go on RV trips worry-free by treating your RV roof with these amazing coating and sealants that keep the moisture out and mold away.
Your RV is your home on the road, and a very important part of your home is the roof. An RV’s roof is exposed to the harshest elements on the road - be it rain, hail, snow, or even strong winds. It can be vulnerable to the forces of nature; therefore, when not maintained properly or even otherwise, the roof can be a silent killer to your RV.
A leaky RV roof means that moisture would seep into the roof and under the wooden boards. Once it gets in, it will only leave havoc in its wake on your cabinets, closets, and walls. Suffice to say, we don’t want that. That is why we bring you the 10 best RV roof coating and sealants so you can travel without worrying about living in a vehicle that is slowly disintegrating. Read on to choose your warrior!
Types of RV Roof Sealants and Coatings
Liquid coatings and sealants are akin to paint. They require surface prepping before application, and the roof will also need to be cleaned and primed beforehand. This is because liquid sealants can take a while to set in fully. The low viscosity of the liquid sealant also requires that it is left alone for a couple of weeks before you paint the surface. The best type of liquid coating and sealant is silicone-based.
If you do not want to wait a few weeks for the liquid sealant to dry and require a quick job, then sealing tape is the option for you. It requires no prior prepping and only needs to be applied to the damaged area. The tape has elasticity and adhesive that effectively bonds the area and expands and contracts in sync with the weather. Sealing tapes that are of good quality can last years before needing renewal.
