C-Forum

I hate asking an adhesive question. I'm re-installing a seat in a poly boat that was originally installed crookedly. It looks like the manufacturer used some kind of 2 sided tape to stick it down.
I looked at available contact cements, and there is a water based one that looks like it would be easy on the plastic and the foam. I was also considering using marine Goop. I have seen in past that folks suggest weldwood in the red can, but we can’t get that product here in Canada. The seat will also be held in with two thwarts. Thoughts?

I believe the Canadian equivalent to the red Weldwood is LePage Pres-tite. The Solvent free/water based stuff doesn't work nearly as well, and isn't waterproof.

Thanks, I had looked at that one but wasn't sure about the solvents on the poly and foam.. But now that I think about it I've used that product on royalex boats to glue in knee pads.

Give Sikaflex 291 Long cure a try at $12 a tube, a Blue Water Marine Adhesive/Sealant and Bedding compound, or so the label calls it. Heven't used it on Poly but it works well on everything so far. Small risk for the dollar. Probably have to get it at Marine Chandler.

I'd be curious about this. We used Sikaflex to attach polycarbonate aviation canopies to the airplanes and it works great.

I d go with the contact cement. It may or might not stick as well as some other adhesives but it's easy to remove if at some point you want to get the saddle back out. Also, bulkhead/saddles are usually held in pretty well by thwarts.
