I'm using pva glue on the base of some of my models for water effects, so mixed with a little bit of blue ink. The problem is I can't get the stuff to dry completely, a week after I applied it to the model's bases it is still a bit sticky. Is there anything i can do to get rid of the stickiness and make it dry properly?
Its not just because of the ink either, because there is a bit on my pallet that didn't get ink in it and its been there for around a month and is still sticky. I just tried brushing some water onto the model's bases to see if that would do anything, but it didn't. I'm considering putting a thin layer of blue ink on top, but that may make the bases too dark.
Any idea would be appreciated.
If its in big blobs, it wont dry, it needs to be a thin layer, thats the problem I assume.
Multiple thin layers letting each one dry completely. It'll look like crap but at least it will dry thoroughly and kinda have the same look as water effects.
Maybe its too warm? I dunno, there has to be a reason for it.
Is it old glue? Maybe you have had it sitting around too long and then when you o to use it the glue has separated. Curious, very curious.
The Great Plague meets The Devourer of The Galaxy. What does that make us?
PVA shouldn't have a shelf life as it doesn't rely on a chemical reaction to set it. Technically it should never get old.
I'm pretty sure the weather is not too hot here. Its winter so it has been around 6-20 degrees C, which is pretty mild. Even so, I put one of the seaguard in the freezer last night just to see what would happen, this morning he is still a bit sticky, maybe a tiny bit less than the others. I didn't use varnish, and the glue is pretty new, 6-7 months max.
Even if there was something I could put over the top to seal it in that would be good, because being sticky they pick up foam crap when transporting and dust/hair sticks to them.. I don't have any varnish though.
