What is a caravan sealant and what are its advantages?

 A sealant is a substance, while contained in a liquid state, which hardens after being applied. This simple action allows it to penetrate small fissures, holes and crevices to be mechanically sealed. They are used as insulators in all kinds of situations.

There are many types of sealant available that differ in their chemical composition. The most common are polyurethane sealants, which are widely used in glazing tasks, silicone sealants, preferred to relieve moisture problems, and the strongest, acrylic.

Before buying a sealant, you should always take into account the place where you are going to install it to know the type that will best accommodate, because you may need a product resistant to UV rays or temperature. 

A sealer, or sealant, is nothing more than a chemical capable of penetrating cracks and fissures for the purpose of isolating them from moisture, gases, and even temperatures. This goes from liquid to solid state when applied, so they can be applied regardless of the shape of the place of application, which makes them reliable and versatile.

Here’s how to apply a caravan sealant

On newer caravans, it is not necessary to remove the old sealant before applying a new one, unless it comes off. You can simply touch up the affected areas just above the old product.

Get a caulking gun and then apply it sparingly. A thin line is usually sufficient for the purpose. Do not hesitate to ask for help!

If you don’t feel comfortable re-caulking your RV on your own or if you want to save time, call the professionals! Make an appointment with your caravan dealer for an annual inspection. Above all, don’t let water damage ruin your next camping trip!

We know that all sealants have a lifetime. Over time, they will dry out from enduring exposure to UV rays, the stirring induced by the travel will cause cracks which will eventually mean that the water will eventually seep in.

So what are the two most important factors in preventing water damage from caulk failure? Vigilance and cleanliness.

The best way to prevent water infiltration could not be simpler: inspect your RV regularly and keep it clean as a new penny! By keeping the exterior of your RV clean, you will be able to easily spot problems quickly, since the build-up of dirt on your vehicle will mask the deterioration of the sealant.

The bottom line
