I have an unheated shop in New England. In the cold weather, I always do glue-ups in the house. I use Titebond III.
During the Spring and Fall, the temperature is often high enough to glue-up in the shop during the day, but then drops below the recommended temperature at night. In this situation, I haul the piece into the house for the night. I wondered if this is necessary. Using the form at titebond.com, I asked how long after glue-up the temperature is important.
I received an excellent response in just 30 minutes. I thought I would share this information, as well as give a big thumbs-up to the customer service.
Titebond III will not chemically perform at or below its stated Chalk temperature of 47° F. If you reduce the temperature of the wood, glue or room below the chalking temperature, the glue does not coalesce (form a continuous film) on drying. This is evidenced by a dried film which is whiter than normal and looks “chalky.” Where the bond is formed at all, the resultant strength of a chalked glue joint is lower than normal and will always remain weak and often times will fail.
In regards to timeframe, the temperature really needs to be maintained for a minimum of 24 hours after glue up. At temperatures closer to the 47° F, you may want to wait 36 hours to be sure the glue has dried completely.
