Glued together some piping for an extractor fan. Roughed the edges up and everything but the glue did almost nothing. I used a ton of duct tape to secure the joins since i didnt trust the glue on its own.
In the end i broke out the old poly cement from my model making days which did the job properly.
"I made some guttering by cutting 2 PVC pipes in half along its length thinking this stuff would glue the overlapping ends together.WRONG. I used GORILLA GLUE eventually,although it expands like expanding foam it really grips anything.Messy though. This Pipe Weld stuff might only work with a pipe pushed into a smaller diameter one for a permanent join and thats it."
