Can Coroplast signs get wet?

Yes. Coroplast is corrugated polypropylene, a plastic that does not absorb water, so getting it wet will not damage the board or cause it to warp.

• Rain, snow, sprinklers, and humidity have no effect on the material itself.
• The printed surface stays intact through wet conditions and dries clean.
• Because it shrugs off moisture, it is the default pick for yard signs and event directional signage.

If a sign gets dirty, a quick wipe with a damp cloth is all it needs.
