It requires moisture for the glue to work. On large Styrofoam surfaces, curing time can be long if you rely on room humidity to seep into the joint.

2017年3月10日 · Styrofoam safe paints: I don't have any specific suggestion here. You will have a hard time using a brush given the rough surface. You might need to use a cloth or something similar to work the paint into all the holes. Let it dry and repeat the process. It will get easier each time as it gets smoother.

2023年3月2日 · Put Styrofoam in acetone. It dissolves into some goo. Stick the goo in a mold and wait for it to harden. When I try it, the goo goes into the mold looking good. But after it hardens, it's full of bubbles. It isn't clear where the bubbles are coming from. The air in the Styrofoam bubbles off as the Styrofoam dissolves and shrinks to a tiny ...

This would allow you to use a slower-acting glue for the shell/thumbtack bond, as well as allow precise placing of the tack-mounted shells once they're bonded.

Though it works with most, Krazy Glue cannot bond all materials. For best results, please do not use on paper, foam, rear view mirrors, polyethylene, Teflon® or other fluorocarbons.

2016年10月27日 · I frequently make cards for my friends and family instead of purchasing them, which I very much enjoy, but the bane of my existence is gluing all the pieces together. It is always a struggle to decide which glue to use. Note: in this context, thin paper means sketching or drawing paper, construction paper and tissue paper. A synopsis of my glue ...

2024年12月8日 · I glued some ceramic cup holders that were delivered broken using Uhu epoxy glue. This glue is supposed to be good for temperatures of up to 100º C, but I wonder about the safety concerns if I use these cups to drink from them (even when excluding hot beverages).
