How to repair a plastic FIMCO sprayer tank?

Justin SE IOWA · May 30, 2012

I have a 30 gallon FIMCO sprayer tank and it has a couple spots in the bottom where it has worn through from sliding around on my carry-all. Is there some kind on epoxy that will actually stick to it? Or is there a better way to fix it? Thanks in advance

I know there used to be welding kits for plastic
tanks. Sorta a soldering iron with a way to feed in
plastic resin.

If I remember right they are kinda spendy so your
best bet may be to get a new tank.

I'd go to the local parts house or farm supply and get some plastic rated epoxy and try it. There are a lot of products like that out there. If it won't work, you won't be out very much.

Take the tank off and turn it up side down. The tank is more than likely Polyethelene. It is heat weldable. Using a 30 to 35 watt pencil style soldering iron and a dimmer switch for incandescent bulbs for heat. and polyethelene strips for welding rod, (cheap frisbies work, milk jugs are too thin. Polyethelene drinking tumbler is also good.)
clean the soldering iron with steel wool to remove all solder. Use the dimmer to control the heat. it needs to just melt the poly. Practice making a full penetration weld and filling it as you go. the tip can actually go through into the tank. Billd weld as you go. It takes a little time to get the hang of it, but it is no harder than welding saheetmetal, and well worth trying. Jim
