Can 303 Protectant be used over the top of EPDM for RV once it's cured and how long should I wait after applying? We

Question

We've already applied liquid roof which has become black with mold as we live in an area with TONS of pollen.  Best advice for removing mold?  We plan to do another coat and then seal it with 303 Protectant.  We did this with a white hot tub cover 6 years ago and it has kept it white with the extreme mold conditions outside.  We want to protect this roof the same way.

Answer 1

If the mold is underneath the membrane you would need to recoat it.  Many rv owners apply an anti fungicide twice a year on their unit to avoid mold.  Thank you for your question!

Answer 2

Hi Tracey, there is a product called streakmaster i believe they also have a good mold remover.

Thank you
