Paper glue that can withstand outdoor temps from -15 to +100 degrees F. Answered
I have an interpretive pavilion and the thing in question is out of the sun and water, however it gets full temperature range for Northern Illinois. From as low as negative 15 up to 100 degree Fahrenheit.
I have a poster to attach to poster board and then it sits against plexiglass. The glue squares that are spongy plastic didn't hold photos to plastic last year, so I am trying to have photos printed on poster and need to make it stiff by either laminating or gluing to poster board (paper).
What glue can handle such extreme temperatures during the year and hold paper to paper essentially?
