Glue with long open time
I did a Google search and found nothing relevant.
I am in the planning stage for a project that will require gluing up large plywood pieces into dadod and doweled joints. Because of the size of the units involved, I need to find a glue with a long open time, perhaps, 30 to 45 minutes for each assembly. Any suggestions as to the type of glue I should be looking at? I usually use Titebond (II), which I push to 10 minutes on occasion, but don't think I can keep it open long enough for this project. ____________________ Bill Waller New Eagle, PA |

Glue with long open time
How about using a 2-part epoxy like System 3? I'm using it on the new
windows I'm making and it works well. Over 1 hr of working time before setting and 24 hr cure time. Joe T |

It says 15 minutes, but I expect it is rather longer than that. I haven't tried this, but I bet if you added a small amount of water, it will also add some time without degrading it significantly. If you watch 15 minutes go by on a clock, it is an awfully long time to be doing an assemble. I once was afraid I couldn't do it because the assembly was so complicated, and it wound up taking all of 5 minutes. |

He seems to use it fairly often. I've not seen this stuff on the shelves of HD or Lowes but I believe you can purchase it online fairly easily. I also believe (possibly incorrectly) that Hide Glue will give you a long open time as well. Cheers, cc |

Glue with long open time
some glues with long open times:
recorcinol urea formaldehide epoxy polyurethane hide latex caulking they have pretty different properties. you'll have to determine which one is right for your application. |

Glue with long open time
Garrett Wade (dot com) has a wood glue with 30 minute open time, it's got "extra strength", too. I couldn't find it anywhere else, it is '202GF' as opposed to '2002GF' which is found at Lee Valley. Never tried it tho... -- Alex - "newbie_neander" woodworker cravdraa_at-yahoo_dot-com not my site: http://www.e-sword.net/ |

I usually use Titebond (II), which I push to 10 minutes on occasion, but don't think I can keep it open long enough for this project. Unibond 800. Its a two-part urea-formaldehyde glue. All time parameters (pot time, open time, and clamp time) are somewhat a function of the mix ratio, and of temperature. I've had very good luck using it for complex glue-ups. It cleans up with warm soapy water until it cures. Full cure takes 12 hours or more, again somewhat a function of mix ratio and temperature. The powdered catalyst is available in three color grades, light, medium, and dark. Light seems a good match for hard maple, medium for red maple and red oak, dark for cherry. I have not tried matching any other wood species. I suspect you can mix different color catalyst to get an "in-between" color, but I have not tried that. Be aware of a few things. This stuff is not good for your lungs. Mix and apply in an area with good ventilation, and wear a respirator mask with organics filters. You may notice some eye irritation with long exposure. If that happens, take a break away from the work area for a few minutes. Wear gloves (nitrile seems OK). I obtained mine on the web, from VacuPress.

I expect the extended is also, though I haven't tried it. |

My local Ace Hardware carries DAP plastic resin glue.

Yes, that is the same as (or very similar to) the Unibond product. I've also seen a "precatylized" plastic resin glue. This is a powder that you mix with water. I don't know much about it. It seems that having the catalyst pre-mixed is a convenience, but the probable trade-off being that you don't get to adjust the cure times by adjusting the mix ratio. Its available on the JoeWoodworker.com / VeneerSupplies.com website. -- Art |

Glue with long open time
Peter recalled the following:
Brush hardener/catalyst on other surface (this is formic acid i.i.r.c.) Isn't formic acid what the Fire Ants inject into your skin that causes the burning/itching? Wouldn't want to get that on anything. I just bought TiteBond Extended Open Time glue. The description on the bottle says its similar to TiteBond II, only it's white instead of yellow. |
