Weatherproofing Corrugated Cardboard
I have some corrugated cardboard
halloween decorations that I would like
to put out on the lawn. Last year, when
they got a little wet, they curled and
"melted" a bit. BTW, las Halloween was
constant rain. Does anyone know of a
way to waterproof the cardboard? The
surface is black colored paper.
Interrnally, it is like any other
corrugated cardboard.
