A little something about Elmer's glue as admix.
I've spent a quite a bit of my time trying to make strong recipes.
This is not even close to my strongest recipe but it is made with Elmer's glue
This window for one of my Japanese lanterns is still wet, 3 days old. Once cured it will be snow white when dry and unbreakable in my hands. I've tested this.
It's already been scraped with a knife, filed, and brushed with a steel wire brush to expost the ags.
That is an AA battery to judge size
I have frozen and thawed this recipe and left it out in the weather for about 3 months. It's plenty waterproof, and plenty strong.Thank you Elmers!:)
