Weldon 40? Need advice for f2f sheet glueing

[Treehrtsme]

Finally got me well done 40. Got plenty of acrylic. Figured I'd go big and go home and glue to 24x24 8-in cell cast colored sheets together. After one of my last thread full of people saying they do this for a living and well down 40 is a way to go I was hoping to get some advice from those people on how to proceed, what the dilution would be helpful and if there's a particular technique to slapping a 24x24-in sheet on top of another while using glue and avoiding air bubbles or any light bleed through that may alter color?

What I learned is that weld-on 40 is very thin and will run everywhere. More importantly is use it in a very well ventilated area. I forget what chemicals are in it, but they are very bad for your health.

I've heard, I was going to run it with a respirator first go. I know they sell 3036 or 5 6 is it to actually bring down the viscosity of this so I was under the impression it'd be much thicker

Acrylic Fabrication Q & A

I am very active on a similar mega-thread elsewhere but I couldn't find an active one here on R2R. @Troylee started the Acrylic 101!!!!! thread a while back, but it doesn't look like he's very active here anymore. Maybe this thread will suck him back in, he has great advice. SHORT CUT LIST...

This helped me immensely!!

I recommend the “pins method”, always clean surfaces after sanding and prior to welding with warm soapy water, then wash soap/hard water off with RO water! — every acrylic weld I’ve done without any soapy water cleaning has snapped apart with mild to moderate force!
