Coping joint- Deck-o-Seal, Soudaseal, Sikaflex,Vulkem

[gsxrken]

Which is the best polyurethane-based product out there?

Some googling seems to turn up some dissatisfaction with Deck-o-Seal, but it may just be that it is the most-widely used product and thus has the most stories.

Any favorites, or never-agains, out there? thanks

I'm in for some answers as well. I need to do this in the next month or so.

I did mine 3 years ago with Vulkem and it has held up very well, hot summers and cold winters. It's a bit on the expensive side but it's a job I don't want to do too often.

Sikaflex here.... 18 months ago. Been very satisfied with its performance so far.

I backfilled the joint with sand first and therefore used less product which saved money. Stuff was very fluid and self leveling, easy to apply, and adheres very tightly to concrete surface after setting up. Don't install on a windy day or junk will get stuck in the surface while it sets up. Does take a while to setup hard....seems like at least 24-36 hours.
