Waterproofing protest signs?

[yasmina27]

Does anyone know of a way to waterproof the signs you use at protests?

We have some wonderful signs from both of the protests in Jan. and Mar. My husband today said that if it wasn't for the possibility of rain, he would like to put our "Republicans Against the War" sign in our front yard - a main back road to a major highway. (Yes, he is a republican - he hates * as much as we do and can't wait for the next march. Anyone know when it will be??)

The local repuke chairman (or whatever) lives up the street from us and our house is right across the street from a polling place. So anything we put in our yard gets alot of exposure! We love to irritate this mostly conservative community!

PS. Am going to cross-post to GD for greater exposure.

Many thanks in advance!

1. Look for a laminator in the yellow pages and call them for advice-

or go to a Sign shop and buy a few feet/yards of clear vinyl and apply it over your graphics.
That'll do it.

2. Clear plastic tape..

I have one I've been using for years. I used 3 inch wide, clear plastic packing tape to cover every inch of the sign (and the stick it's mounted on. It's totally rainproof, but I had another done the same way that I left in the back of my truck and it got destroyed when enough standing water accumulated to seep into the sign and make it run. Hydrostatic pressure is relentless.

3. This works

You can also staple clear plastic sheeting onto the sign.

4. Depends on material.

If wood, typical outdoor acrylic varnish is fine.

Cardboard can also be varnished, probably.

Test a piece other than the signs, using the same base material and written with the same inks.

Expect color change in the base material, but not an exceptional decrease in transparency.

There are waterproofing spray acrylics. I use waterproofing spray on game boards. This should be fine for signs that are carried in parades because the exposure time to adverse weather is limited.
