I'm going to have to remove the rubber roof on my rv and replace some of the wood underneath. Can liquid EDPM be used to go over the wood roof without installing a rubber roof first?

Hi here are the instructions for wood applications

When working with any wood application you first want to seal it with the ProFlex Primer. Porous and unstable substrates will not accept the application and will result in an ineffective cure. When working with applications over existing painted wood, clean the surface with soap and water to rid it of residual oils, debris and dirt. Scrape off any flaking areas. If you have washed the roof, ensure that enough days have passed so that any water absorbed into the wood has evaporated. When working with large commercial roofing applications, inspect the joints and seams. If there are any gaps 1/16 inch or larger, you will need reinforcement or filling. Wood application are not covered by warranty as it is impossible to verify the condition of the wood i.e. rotten wood or wood that has absorbed water.
