For my current project, I have decided to switch from my usual Titebond to an archival quality glue. My (limited) understanding of glue technology is that Titebond glue is acidic.
Weldbond offers a line of PVA glues that are supposedly non-acidic. Please correct me if I’m wrong.
My confusion is that references here on SOS refer to Weldbond Universal Adhesive. When I look this up on the internet I’m offered Weldbond Multi Surface Adhesive. Are these the same, just rebranded?
Thank you Roger for your interesting question.
I seen many conversations on SOS on this subject, consequently as an amateur model builder myself I have spent money on many different wood glues. In my opinion there are 3 main stream types of glue wood base modellers can use. The question to be asked every time you want to glue something together is, how much time do I have to hold the two pieces together, with what clamps should I use.
24 hours, then I use ordinary yellow wood glue bought at Home depot, or Rona, this means 12 to 24 hours drying time. This glue holds fast, strong and is most inflexible to pull apart, although it is water soluble. Given a lot of time the components soaked in water will eventually pull apart.
2 to 5 minute, I now use the cheapest White Paper glues, Elmers School glue bought at the Dollar Store. It dries clear, can be stained, varnished, holds fast, but will not tolerate too much pressure, pulling apart. It is water soluble, cleans up well, and if necessary can be gently reworked to pulled apart after dampening with water, and lightly sand glued areas for reworking.
3 - 5 seconds, definitely Instant glue, almost any CA glue works well. The discussion on its acidity is well covered. But again it can be pulled apart, (broken at the joining surfaces with a little damage more often than not.
So answer your own question, how much time do I have when gluing parts together.
Hope this helps. Cheers Richard.
