Here is the list of the equipment that you'll need:

  • A bucket

  • Mild soap

  • Lawn hose

  • soft and smooth brush

  • Waterproofing product

  • Ladder (a folding or step ladder is preferable)

Clean the Camper Properly

  • It is good to leave the tent in the sunshine for two to three hours to allow all the mold and mild to die naturally.

  • Before applying chemicals to them, dry brush off any leftover debris.

  • Ensure the camper is clean and clear of debris before using the waterproofing agent.

  • Put the camper in a clear space outside your house, away from trees, and near a water supply to wash it.

  • After that, expand the camper to its maximum size before cleaning it with a light soap or detergent and a smooth brush.

  • Avoid forcefully scrubbing it since doing so might harm the cloth.

  • You may have to exert a little force if the fabric is untidy, such as if it contains bird feces, mold, or fungus. But that relies on the specifics of the issue, like the material type and how filthy the camper is.

  • Ensure the chemicals you use are vinyl compatible if the camper's exterior is made of vinyl; otherwise, you risk damaging the coating and reducing its waterproofness.

Use vinyl-safe solutions to repair or wash the vinyl components of the pop-up camper's material. For example, if you use a 303 fabric guard waterproofing product, ensure it's not on the vinyl surface. This fabric protector doesn't work well with campers with a mix of canvas and vinyl elements.

  • Add the first layer of paint to the canvas on the damaged regions using the spray bottle for smaller parts.

  • Avoid coating the vinyl section, and hide such places with a cardboard sheet when spraying.

  • Alternatively, you can protect them with adhesive tape to prevent staining. If you accidentally overspray such areas, clean them off right away.

  • Since you require more material for the bigger parts, using a paintbrush will be convenient. Rub it thoroughly across the entire area after pouring it into a container.

  • After letting it dry, apply an additional layer. Seal with a seam sealant, examine for any areas still exposed by showering them with water, and repeat as necessary.
