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. |

I'd probably try some Kamp Dry. Sporting goods or camping stores will have. Might be tough to wet down corrugation's. Maybe if exposed you could put hot melt adhesive on seams. Frank |

I did exactly the same thing a few years ago. Made a really kewl flying saucer out of cardboard, complete with flashing lights, and put it outside with a couple of "aliens". Then the rains came and ruined it. Became one soggy mass of painted cardboard, slumped over the bushes. Very sad. No, there's no practical way to prevent this. Use something else or don't put it outside. (You *could* cover it in many coats of epoxy paint or fiberglass, but then you would no longer be working with just cardboard.)

You can try varnish or several other products that will slow down the process, but it still will get in the edges and that will be the end of it. -- Joseph Meehan Dia duit |

There is a plastic version - formed like corrugated, but all plastic. I would check craft stores for a more suitable surface. There is also a painting ground, for oil or acryllic, made like masonite but with a "primer" on it. Probably would only have to waterproof the edge, if anything. I can't imagine anything that would reliably coat the inside and outside of corrugated cardboard. |

Weatherproofing Corrugated Cardboard
"Joshua Putnam" wrote in message It's pretty easy to do with canning wax and a big paint brush. Melt the wax in a double-boiler and brush it onto the cardboard slowly so it soaks in while it's still molten. Commercially, corrugated is wax dipped for waterproofing for the seafood industry. Your idea should work well. |

Weatherproofing Corrugated Cardboard

It's pretty easy to do with canning wax and a big paint brush. Melt the wax in a double-boiler and brush it onto the cardboard slowly so it soaks in while it's still molten. (The thermal mass of wax in the brush will keep it hot longer -- if you brush too fast, it will solidify before it penetrates.) Take extra care on the edges to make sure it soaks into the center corrugation as well as the outer layers. Then make a second, faster pass over the edges that will block the passageways so water can run inside. Of all this suggestions given, this is the only one that has even a *chance* of working. I know, because my Halloween project was practically saturated with paint, and it did *nothing* go prevent it turning into a soggy mess. But even the wax might not do it. I guess the only sure way to do this would be to use some kind of plastic (someone suggested the cardboard-like corrugated stuff). -- Save the Planet Kill Yourself - motto of the Church of Euthanasia (http://www.churchofeuthanasia.org/) |

Getting paint to stick may be another issue though. Art supply shops & framing places might have it. DAGS for coroplast. |

Your idea should work well. I have unloaded many a Corrugated Cardboard box of vegetables that were soaking wet and covered with ice. It will hold up if done correctly. No doubts |
