I think I'm going to start wheatpasting propaganda to the concrete wall protecting my own dumpster, on the back side facing my compost heap.
No one but the folk who hang out back here will see it, but also, no one but me would take it down, so it can stay up for a long time.
So, @ me with some good black and white shit I can print on some basic whatever-size-paper-Americans-use
@emsenn I'm assuming wheatpaste is an organic glue made from flour, but this is my first time encountering that particular phrase.
Just flour and water?
2 parts high-gluten flour to 3 parts water bring to a boil add another part water simmer for an hour.
Makes a fairly thick paste that's great for adhering posters for a looong time.
This has my wheels turning.
I used to make a clay out of a similar mixture with the addition of corn starch and salt when I was a kid.
I imagine it dries white, and isn't anything close to water proof but is otherwise pretty strong?
I'm looking for a mixture I can add to paper to stiffen it enough that it can stand up to children playing with it.
Right now, my best options are soy wax for some situations and PVA glue for others but I'm looking to find an alternative to PVA.
@ajroach42 Some people add both of those to their wheatpaste mixture!
I tend to add a wee bit of sugar to aid its gumminess when first applied so I can get the poster flat and stuck faster.
It's usually a thing enough layer that it's pretty clear - most posters you see put up have a layer of wheatpaste on the back and then one put over top, and that's why they peel and fade in that distinctive way - they're not waterproof, but they're definitely more water resistant than you'd expect. 1/n
@ajroach42 check the stores you would but you can probably find preprepared dry wheatpaste mix at craft stores, hardware stores, and places like my local scrap exchange.
To try it out without the labour of mixing up a batch.
@ajroach42 I imagine application technique is really going to make the difference here - brushed versus sprayed, how thin a coat or if multiple, etc.
Are you familiar with lacquering or clearcoating in general? (I'm not qualified to type a how-to, but if "no," find one, lol.)
@emsenn I've done lots of clear coating (in a spray adhesive) for book covers and CD cases and other paper products 5 - 7 years ago, before I gave much thought to the impact I was having as an individual.
Mostly I've used Aerosol sprays, which I'm obviously trying to avoid at this point.
I'll definitely look in to a tutorial.
@emsenn I think I'm going to start with printing, cutting, and then waxing the paper and see what that gives me in terms of stability, and then start experimenting with the addition of wheatpaste at various points in the process, to see what kind of a result that gets me.
@ajroach42 how do you apply the wax?
@emsenn I've tried two methods.
One is to heat it until it melts in a wide pan, and then dip the paper in to it, raise it out and let it drain. The other is to apply it with a brush.
Both work okay, but I've never tried either on printed paper.
@ajroach42 How do "let it drain" without whatever holds it above the surface leaving a significant mark?
@emsenn In that instance, I wasn't concerned about the physical appearance too much, so I had punched a hole in the top and run some twine through it. When I was done, I trimmed off the area where the twine had been.
I used the twine to drag it through the wax, and then to hang it over the tray.
@ajroach42 That is clever and outside any of the possibilities I thought of!
And it wouldn't be too hard to remelt the... chads? and scoop out the paper and reclaim most of the wax.
That sounds like a good solution. Maybe use a hot knife to do the cut so the wax reseals?
Those are good ideas that I did not attempt.
I'll try that once I have the printed paper ready. I'm going to try to make a spaceship.
@ajroach42 Here's a photo of a random scrap of paper glued down with wheatpaste; it's dry, but clearly fresh.
@emsenn neat! That's clearer than I expected.
@ajroach42 I figured it would be which is why I wanted to give you a demo :D
Now to wait for the bigger batch to cool a bit then I'll put up posters
@ajroach42 And this is what happens when I try and pull it up.
