I have recently been looking on the inter net for information about patch kits that are used for the repair of rubber and metal roofs. I have looked at over ten different kits from different suppliers and none of them have any primer tape activator in them. I can assure you that if you don't use a primer that your repair will only be tempery. I use to work in a research and development lab working with epdm and other single ply rubbers. I have conducted many test on using tape with primer and without primer. In every case the non primed tape failed over time. If you don't believe me go out and pull on the edge of a repair done without primer you will see that it peels up easily. The reason that most suppliers don't use primer is because primer is flammable and can't be shipped normal channels. So they simply say clean thoroughly and apply patch. There are only two companies that have solved this problem and have primer in their patch kits. One is Firestone Building Products that has a pond patch kit with primer, tape, roller, gloves and scrubber pad. The other is Rooftop which is a trade marked division of flatroofsolutions.com who has a multi surface patch kit with white rubber tape, primer , roller, gloves and scrubber pad.
