[TheForge] Gorilla Glue

[Don Sinclaire]

Gorrilla Glue is a polyurethane glue.  Elmer's calls their version Probond.
It is waterproof, and I have used it for truck boxes, oak doors, and
furniture.  It is excellent glue if you want longer working time than with
traditional white glue, such as when making bent laminations for furniture.
As it cures, it foams and fills small gaps.  It does take a day to dry
properly.  After it is dry, you can use a knife or chisel to clean ups
anything that was extruded from the joint.  That is usually a cleaner way to
remove excess than wiping it while wet...that just spreads it around.  Any
glue that got on the face of the oak doors seemed to sand away and left no
significant stain and did not bother the subsequent oil-based stain or
polyurethane.  

Don't buy more than you can use in a year since it will go bad as it absorbs
moisture from the air.  It may go bad faster if you are in a humid area.  I
write the date on the bottle when I open it since I don't want to use
outdated glue.  For large, non-critical areas I still use white glue, since
the polyurethane glue costs about 3x as much.  I have had black hands from
using my coal forge, but at least that comes off.  Only time seems to get
rid of the glue stains on skin.  I have started wearing latex gloves when
gluing a larger project.
