acrylic glue - which one??

Well, there's a store here in Denver called Plasticare and evidently they have every glue product you could ever need. Which one do I want to bond pieces of acrylic together? I'm making a sort of form for a moss wall out of acrylic I got at Home Depot. So, it doesn't have to look perfect, but is hopefully inexpensive, easy to work with, and reliable.

Weld-on number something?

Depends on the pieces you are working with.

If you are cutting panels with a band-saw or table-saw and then trying to butt join your cut edge to a flat face you really need an epoxy or something that can gap fill.

Weld-on #4 can work great if you are bonding a lap joint or are working with perfectly flat surfaces to butt together. You have to apply it a bit liberally and work fast because it will dry quickly. A syringe tip bottle is great for applying, but a brush can work too. Once it's cured the Acrylic panels will break before the joint will fail.

#3 dries too quickly and is a PITA to use.

#16 is a little thicker and doesn't dry as quickly as #3 or #4, but you still can't dawdle. It won't provide a bond stronger than the base material, but I doubt you need that either.

Honestly though, cyanoacrylate (superglue) also bonds acylic very well if you have nice flat surfaces to join. I've used it to laminate sheets of Acrylic together prior to machining (when i was out of #4).

What I don't know, however, is which is best for long term water submersion.

Weld On products are the best for acrylic. But no need to spend 10 dollars just for a moss wall. What I would do is just buy a screen sheet (like the ones for windows, doors, etc.) and just sew it shut using fishing line.

Or, if you want to go on another cheap route but still want to use acrylic... Try super glue and then back it up with silicone. It works so far for my false wall I made in my tank. I'm sure silicone + superglue can withstand a simple moss wall.

Do you have a link to a pic of the moss wall?

I'll second the Weld on products. I used IPS Weld On 16 for my last DIY acrylic project. My scores weren't the straightest. If I had done a better job on the edges I would have used Weld On 4.
