What happens if you use this below 55°F? And what happens if temps go below 32°F overnight?

pretty sure this stuff will freeze like water, so i wouldn't use it if the temp goes below freezing. I think lower temps slows down the hardening process. This stuff really works well when applied as per directions

How do you open the bottle?

You can punch a hole through the top of the nozzle or cut the tip open. Thank you for your inquiry.

I used copper green wood preservative on rotted wood hoping it would harden the wood but didn't. can i use this on top of it to harden?

Probably. I don’t know why the copper preservative would impact the Elmer’s. I’ve used Elmer’s, solvent based wood hardener, and epoxy wood hardener. First for any of them to work well the wood had to be dried out. Of the 3, the solvent based products do the best job of penetrating deeply but the hardening is somewhat limited. I find that the epoxy is probably the best compromise for penetrating and hardening but it is messy and a bit expensive. I like the Elmer’s the most for sealing and hardening the surface and the layer immediately under it.

How long after applying this Elmers 'hardener' before I can put wood filler in the crack? It's less than a third of an inch at widest part.

Depending upon drying conditions, I give it 4-6 hours minimum. If weather permits, I let it dry over night then add the wood filler.
