   Depending on temperature, for standard PVA, one hour should do it.

   For Urea Formaldehyde, you need to clamp about 5 x gel time, which can be up to 24 hours.

   Basically, for PVA, once the glue squeezeout has turned clear, wait half an hour and then remove the clamps.  As the glue is still soft at this stage, ensure that flat panels are laid flat and frames are laid down and kept square.

   Hope that this helps,

   cheers,

   An hour for Titebond II is OK, but don't put any serious stress on the joint for 12 hrs.

   Same advice. I switched to Titebond II after a few of us ran the following test: We glued short pieces of poplar to poplar, and red oak to red oak, and threw them into a bucket of water overnight. In the morning the Titebond pieces had separated but the Titebond II pieces had not. We didn't go any further to determine the ultimate moisture limitation of Titebond II.

   Not a surprise since Tightbond is not water resistant and Tightbond II is.

   A disadvantage of Tightbond II is that it won't wash out of your clothes.  So, you'll have peramanent stains in your work clothes if you use it.

   One hour min. to remove clamps but two hours should remove risks. Also, if you're gluing multiples, remember you can glue as many as will fit in your clamps at once, just don't forget to skip the glue where you don't want it, and to counter-clamp on the other side of the original clamps to counter-act the bowing effect. It is possible to over clamp, which squeezes out too much glue, go firm but don't over crank those puppies.

   good luck, Dan

   It's true that Tightbond doesn't wash out, BUT the other (one step) alternative is polyurethane and never mind the clothes, how about the skin!

   I seldom get glue on my clothes. This has not been a driving force in my life. My work clothes (e.g., every day clothes) are already stained with tears, blood, paint, etc. If I wear them to dinner they also get stained with wine and spaghetti  sauce.  The answer is to wash in hot water and use whatever detergent my wife uses. I'm not sure what it is.

   I have always used Tite-bond II and I have limited space for clamping and have only put things in clamps for as little as 15-20 minutes, and set them aside until I have all the glue-ups done , then run them through the plainer and never had any of them come apart, I have left things in clamps over night, but in depends on my time frame and where I end up at that time of day, when I glue end grain I always glue size,let me explain , put a thin coat of glue on the surface that your gluing and let dry, some water the glue down 50/50, I don't, then when your ready to put that together , put a small amount of glue on one surface and put together and clamp, I'm a professional furniture builder with over 20 years behind me ,

   If you need more help or questions answered , don't be afraid to ask, no question is to stupid ask, that's how we all learn!

   The clamp and cure times stated on the labels typically are based on 70-75 degrees and 50% relative humidity. For PVA adhesives, the times double for every 10 degree less temperature and 55 degrees is the lowest temperature at which they should be used.

   Clamp time is amount of time for the glue to cure enough that the parts will stay adhered without pressure. But, the adhesive has only developed about 25% of its ultimate strength. It takes PVA adhesives about 12-24 hours to develope 80-90% of their ultimate strength so the bond should not be subjected to any stress for that length of time.

   Thanks, my shop is about 65 degrees so I will factor the time in as you specified.  Thanks for your input..Regards,
