Latest from the Titebond tech team:
The results from yesterday’s poll are in! We asked lead glue guru Bob Behnke (who manages our Technical Support Team) to weigh in on it. He says there’s no right answer; both approaches have their benefits and drawbacks. Here they are:
One-sided gluing is the only way to get invisible glue lines and results in less squeeze-out mess. On the other hand, you must be quick to join the parts within recommended open and assembly times (which can, themselves, be cut in half by less than 8% wood moisture content).
Two-sided gluing results in higher amounts of glue and more water in the glue, which extends working time. On the downside, gluing two sides results in thicker glue lines and a lot more squeeze out. You also use more glue than necessary. (We’d rather you put that extra glue to good use!)
There you have it!
