It’s that time of year again when gluing becomes problematic. Having tried several experiments last winter I figured I’d share my experiences. And I hope others will as well.
So what can you use in the cold? I’m defining cold as between 45 degrees and below freezing.
Titebond III. It’s good down to 45 degree Fahrenheit. It’s pretty forgiving but it will chalk at around 43 degrees.
Titebond Extend-This is a longer open time version of Titebond I. It’s good down to 40 degrees and is actually quite forgiving. That is, it doesn’t chalk easily. But while it won’t chalk it will take forever to dry. In temperatures around 40-45 degrees I have seen Titebond Extend remain wet for several days.
Gorilla Glue (polyurethane)-This stuff works down to at least 40 degrees. It won’t expand as much as it does in warmer temperatures but the bond strength seems to be just as good. It will usually dry in 4-6 hours in the cold. Sometimes more.
Epoxy-When things start hitting the freezing point epoxy was the only thing I could get to work. I used 5 minute epoxy. In cold temperatures you will have plenty of open time even with 5 minute epoxy. The biggest problem I ran into with epoxy was that it basically doesn’t flow at all in the cold. I have noticed this leads to the epoxy not “wetting” the wood. That is, it doesn’t seem to sink into the wood. It will cure though, in in freezing temperatures. Epoxy is obviously the last resort because of cost and the need to mix the resin and hardener. Wear gloves when handling epoxy or you could end up with an allergy to the stuff.
Anyone else got ideas?
