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.

Instead of using cardboard, use coroplast. Same construction as cardboard
but made of vinyl instead of paper. Getting paint to stick may be another
issue though. Art supply shops & framing places might have it.

DAGS for coroplast.
