Hey guys I purchased a large printed vinyl banner (3050mm x 766mm). Due to cost reasons, I want to glue this banner to an aluminum sign and it looks like it is coated, maybe plastic or laminate. I’m located in Australia. Which glue should I use to adhere this banner to the sign? It is outdoor and I don’t want glue to damage the print either.
Neither material is absorbent and both will prevent solvent from evaporating, so a contact cement would be good for this. I don't know what's available in Australia, but 3M makes HI-Strength 90 Spray Adhesive that sticks to both kinds of materials and should hold up outside in the sun and rain. The link says it's for industrial use but a different color can of the same name is sold in the big hardware chains. Disclaimer: I haven't actually tried it myself (but it's used industrially and commercially).
