Etched
Primed
Can you share the products you used to do this? I want to protect the roof in some way also, but not quite sure what to get to do this yet. And what is etched? And why do you need Eterna bond tape?
I'm a painter by trade... Aluminum and galvanized and stainless steel are non porous... so paint does not have anything to grab onto, bare sheet metal is up in the air... some think a good metal primer will hold others don't... so to be safe I always
etch it.... Etching is a chemical reaction that gives the paint something to stick to.... there are some wipe on etches.... and some DE glossers that can work, some painters say wiping it with vinegar will
etch it.... but I like an industrial
etch that is made for that purpose, Sherwin Williams ( might have to order it for you) carries a product called DTM Prime Wash... and that is what I used....it is an acid based coating... if I was using it on aluminum I would go to an industrial paint store and get one that is 2 parts... and Sherwin Williams says their krill primer will work as an
etch... it is acrylic based... but I just wanted to make sure I had no paint failures... Then I primed the roof with Dicor.. metal primer acrylic base ... The eternabond tape is a silicone based tape to put over the seams... it alone without ever coating your whole roof would probably make it so it would never leak! but I want the cooling effect also, so I am going to put the dicor elastomeric roof coating over top of everything ( 2 coats )
