Depending on the manufacturer, the application directions can vary. But in many cases, applying it on your camper roof isn’t hard at all.

Apply it, but make sure that you get proper ventilation in the area where you are applying it.
Prepare the surface of the roof by washing or scrubbing it. Remove loose caulking and roof coatings. Use a brush to apply the coating. Cover the depressions, protrusions and seams, too. Let the coating dry. Apply finishing coat if needed.
