Minimum Temperature For Working With Glue

03/03/2013


From original questioner:

i live in a cold winter climate and work in an uninsulated garage. normal wood glue says to work with a minimum 50 degrees. Is this really necessay or is above freezing OK?

I haven't checked lately but the Titebond Extend bottle says it is good down to 40 degrees (In contrast to regular Titebond which is good down to 50).

Look @ it from a risk/reward perspective. The risk is your work falls apart in someone's house. The cost of the reward for that not happening is to stay with in the guidelines and pay to heat bill. If you are renting I would talk to the landlord and see about a cost sharing for adding insulation.

The reason for the temperature limit is 1) a chemical reaction must occur as the glue cures and 2) the glue must flow well enough to fill the nooks and cranes when the pressure is applied and any excess glue must be able to flow out of the joint.

If the wood or the adhesive itself is too cold when applied, the chemical reaction will not occur quickly enough before the moisture leaves the glue and goes into the wood. And, there is a good risk that the joint will be too thick.

Although you could heat the adhesive to keep it at 70 F, when it hits the cold wood, the adhesive will quickly cool. (Wood takes a long time to warm up, so even though the shop air may be heated an hour or so after you arrive, the wood would still be very cold from the nighttime temperatures.)
