Dear Armco,
Yes, it does stick to steel (and anything else in its way). It is a flashing
membrane, not a steel protection "coating". Basically, the steel should be
cleaned and painted, then a special primer is painted on to help the bond to
either steel, masonry, wood, etc. then the membrane is attached like contact
paper but it is a membrane system with sealants, liquid membrane for
difficult areas, etc. It can not be left exposed to the sun (must be held
back 1/2" from exterior face of masonry) but it performs well under constant
water pressure.

Eric, is it designed to adhere to the steel, and thus "keep water away"? In
that case, this is a more advanced method than just painting the steel,
correct? On modern office buildings, do they still paint the steel?
