Reglazing an Ancient
I am reglazing a 1902 sash, using DAP 33. Does this stuff harden any? Overnight in my 60 degree shop did nothing. Do I dare prime and paint this while it is soft? Please advise. Thanks.

Been a loooooong time since I had to do any glazing.....
Not sure of the exact timeframe..but yes..it will harden up based on temp and humidity. One of the painter guys can probably give you a better idea for the prime and paint question.... Seems like oil based primer has been recommended in the past...but don't hold me to that...
Ahh I should trust myself more....see the painting section of the link...

Thanks GunGuy
That site was helpful. They recommend waiting no fewer than 7 days, and more likely 3-4 weeks to allow the glazing to "skin over". They also recommend a very narrow bedding bead under the glass, which I did not do. Guess I'll start over.

I've almost always prime the glazing a day or two after it's put on..... but it's hard to wait for any length of time when doing work for a customer. I've never had any issues with using an oil primer after 24 hrs. I prefer SWP's 66 glazing over the Dap 33, it's not as oily - keeps my fingers cleaner 
Are you just reglazing glass that's already installed? or has the glass been removed?

Glass was removed
I've been out of touch for a little while. Thanks for the advice on the product competing with DAP 33. It is what my building center had, but I am not shot in the head with it. I have put the sash in my living room with a fireplace, and it is slowly hardening. I have a storm window, so it is not a huge problem.
Thanks for all of the help. With any luck I'll never have to repeat this task.

If your removing the glass, while a small amount of glazing is recommended, I'd use a thin bead of caulk instead - it's quicker/easier and does a good job Apply the caulk, install the glass [with glazing points if needed] and then glaze. It's always best to prime the wood [and let it dry] before glazing and installing the glass.
