117 - A Sticky Situation

This video is an accompaniment to my column in the April 2009 issue of Popular Woodworking Magazine. The article serves as a general review of common woodworking glues and when to use them. The video, however, focuses specifically on urea resin glues. These glues definitely have their advantages: low water content, gap-filling, long open time, and rigid glue lines just to name a few. But keep in mind the one big disadvantage: safety. These glues are pretty nasty and you might be best served considering other options. But with proper precautions (gloves, goggles, and respirator), this glue can be a nice addition to your shop. The two brands I use are DAP Weldwood, and Unibond 800.

what about contact cement for veneer? Would you recomend that?

[TheWoodWhisperer]

@Strykercom1 I'm not really a fan of contact cement for veneering simply because of its flexible properties. I prefer a nice rigid glue line.

How is this in the Cooking subsection in Howto & Style? 0.o

[TheWoodWhisperer]

@TheSimsCreedGuy Excellent question. Wish I knew. I also wish I knew why How To and Style are considered the same category. Obviously, makeup tips and woodworking have so much in common. :)

what about perl glue (water based) my dad restores antiques and that's the only glue that he is using for venering missing bits, or whole re-veneering process.

I heard that some ppl call it "animal glue" (It's stinky by the way)

[TheWoodWhisperer]

@daltoniks Hide/animal glues are an interesting thing. I don't really use them but they are pretty much the oldest adhesives known to man. Many folks still use them.

Now that's what I call a Sticky Situation.

Assuming that Unibond 800 is the same as Urac 185 (both of which are hard to impossible to get in the UK), the resin is the part that contains formaldehyde. The powder is wood dust and ammonium chloride (it has less than 1% of the active component). You can make your own custom filler - you need to go lighter than the target wood, since the resin does darken it somewhat. A precise digital scale helps with this. It's a 90:1 resin / ammonium chloride mix (by weight) for the "standard" setting time

WOW. I had no idea. This explains why my veneer projects always failed. I gave up thinking it was me when I had the wrong glue the entire time. Thanks Mark!!!
