Applying 303® Aerospace Protectant™ to EPDM Rubber Roofs

Clean your RV's rubber roof at least 4 times a year, even more often if you live in an area where there is a lot of pollution (that black stuff that settles on the roof).


Use 303® Aerospace Protectant™ to keep the roofing material clean, to prevent stains and to minimize the messy, though natural, oxidation. Before using 303® A. Protectant, clean the EPDM membrane thoroughly, following the manufacturer's cleaning guidelines.

Spray or mop on.  Allow to soak in for a couple minutes (EPDM, particularly when it hasn't been treated before is quite absorbent). 

Then wipe completely dry using dry cloths by hand or pushed with a mop.  Change cloths as required to make sure treated surface is completely dry. (Drying the 303®'d'suface completely makes the material extremely repellent to dirt, pollution and soiling and it makes the treatment last much longer).

Do the roof a 3 x 3 foot portion at a time.

For your safety, never walk on a wet roof.

In spite of what is claimed on the labels of "rubber roof treatment" products, EPDM rubber roofing does not need to be protected from UV and ozone and certainly not the level of  UV screening protection provided by the world's most powerful UV screening protectant, 303® Aerospace Protectant™.   Instead, the manufacturers exclusively recommend `303®' as a safe and the best way to keep the EPDM clean and looking like new and to minimize the natural oxidation which, as many RVers know, can be quite messy.

HINT:  Some RVers clean their rubber roofs regularly (as the manufacturers recommend), and after each cleaning just treat the part of the rubber roof that can be seen from the ground.  Quick, takes only a little 303® A. Protectant, lasts a long time and their RV looks great!
