I'm planning to attend some demonstration these coming days. However, winter is upon us, and there's going to be rain. And the placards are made of paper; thick paper board, but still paper, which will not withstand anything more than a light drizzle.

Now, you must be thinking: "Use a large umbrella". But the thing is, I need both hands to hold my placard. (Plus, an umbrella is rather unwieldy, and makes you a more attractive target to opponents of the demonstration.)

So, what would you recommend as a solution for keeping my demonstration placards(s) dry and visible?


  • If you suggest using a different material, note that poster longevity is generally low because the police often tears them up or confiscates them. Also, assume there is currently a set of posters that I need to work with and they're paper.
  • The location is Israel/Palestine, and the temperature is low, but markedly above zero.

You could wear rain gear to protect yourself and warm clothes underneath.

For the poster board you can try a clear acrylic spray paint or even get large sheets of thermal laminate to cover your poster board.

With the laminate you can use a simple household iron to seal it and it would be waterproof with the added benefit of being much harder to tear and destroy.

    Can you be more specific about the kind of spray paint you mean? And how that protects the paper? Anyway, lamination is an interesting idea; although I wonder how much time that would take for each poster.

    @einpoklum Any clear polyurethane or acrylic cans of spray paint. Not sure what brands you have available in your location which is why I didn't name any specifically. I would go to a local home improvement or hardware store and grab a can, bring it home, make up a sample poster and try it out in the shower. I am not sure how posters you have but laminating would probably go fairly quick.

    You could also try a corrugated plastic for your poster boards and then a clear poly or acrylic over top, that would work great too!

    More difficult to sketch posters on corrugated plastic, plus it's much more expensive, but I suppose I'll have to consider it.

  • @einpoklum, matt: spray paint in the shower? Apart from speckling the walls with paint, it would be hard avoid breathing the rebound. No reason to do even a quick test inside.

  • Cover the placard with cling film, wrapped round to the back.

  • If the film isn't wide enough, use more strips vertically to make it rain proof.
