Marine safe glue advice needed
#1
Afternoon all,
I am planning on making a sump for my marine tank out of Polystyrene sheet. I have cut and prepared all the pieces, but am stumped as to what glue to use at the joints. I have done some test pieces using hot glue, sealant and a non solvent based Bostic glue, but none of them seem to have the strength required. I am also weary about using any glue which will not withstand exposure to salt water or that may release toxins/ solvents into the water.
If anyone has any previous experience building tanks or sumps out of polystyrene and can offer any advice on what glues they used I'd really appreciate it. The other alternative is that I start again and make it out of glass, but it seems a bit of a waste as I've already got all the polystyrene sheet cut to shape.
In hindsight I should probably have looked into this BEFORE I purchased and cut the plastic, but hey, I always did like learning the hard way.
Stuart.
