How to seal the underside of an RV?
To seal the underside of an RV, you need a powerful jack to uplift the RV; you need to inspect the underside and after that use a sealant. Then, you have to let the sealant dry.

We will go into the details of all the steps below to make it easier for you to seal the underside of an RV.

  1. Use a jack to uplift the RV:
    If you truly want to seal the underside of an RV, you have no other option but to use a jack to lift the RV. The ordinary carjack is not suitable for the RV. The RV is much bulkier than the ordinary car. You will have to get a jack that is especially suitable for RV.

You need to get multiple such jacks to lift the RV.

Only when you uplift the RV can you move on to the next step.

  1. Inspect the underside:
    After that, you have to inspect the RV for any cracks or signs of wear and tear. You have to look out for signs of corrosion as well.

In case there is corrosion or oxidation, you have to first clean the surface of the RV before moving to the next step.

  1. Use a sealant:
    After that, you have to start using a sealant to seal the required spaces.

The sealant should be compatible with the surface. Only, in that case, it makes perfect sense for you to use that sealant.

The width of the applied sealant should be slightly greater than the cracks or the crevices you have to fill up. You shouldn’t apply the sealant unnecessarily.

  1. Let it dry:
    After the application of the sealant, you have to bring down the RV and remove the jacks. However, you cannot start driving around instantly. You have to let the sealant dry. If due to any reason, the sealant is exposed to water before it dries, there is a risk that it will be washed away.

To avoid this, you have to let the sealant dry for at least 24 hours. Only when you let it be for 24 hours, the sealant will settle in. Once the sealant settles in and dries well, you will be able to easily use the RV and take it with you wherever you want.

Sealing the underside of an RV is not an easy task. These 4 steps might seem simple, but the amount of effort and the tools you need to execute these 4 steps are pretty difficult. Keeping this in mind, it is also a good idea to get some professional help if you want to seal the underside of an RV.
