Gluing and adhesives is all about basic technique for the beginner. There is not reason to get into exotic glue or techniques, start simple and build from there.
The best joining is accomplished with adhesives, in conjunction with screws, nails or other fasteners. With the exception of epoxy, too much adhesive will weaken the hold of the materials you are bonding. Rough up smooth surfaces slightly before applying adhesives so they will grip more securely. Apply a thin coat of glue, clamp securely, and allow to dry the recommended amount of time. Wipe away excess glue immediately after clamping.
When gluing up a project it’s inevitable that some of the glue will squeeze out of the joint. It’s best to wait for the glue to "gel up" before scraping it off with a sharp chisel or razor blade. Wiping up the glue before it gels can spread it over the surface of the wood and cause you a lot of sanding later.
Tips and tricks for gluing technique.
Lots of good background info on traditional glues and modern adhesives in this long thread about gluing an Ipe edge to a counter-top. Gorilla Glue were outed last year by Fine Woodworking as poor wood glues in any circumstance. Counter-tops are typically glued with epoxy resin. Epoxy resin prefers to have a sanded surface, unlike conventional wood glues which prefer freshly jointed edges.
Is clamping necessary, and if so, how much? I've got some Elmer's Pro-bond yellow carpenter's glue, and the instructions state: "join mated surfaces snugly and clamp if necessary to maintain contact". This would imply that clamping pressure is not important for gluing effectiveness.
Confused about white versus yellow glue? Or what glue is best for marine applications? Or for repairing antique furniture? Or for securing a loose fitting joint? Or for stabilizing a crack? Or for temporarily holding a part in place? Well, here's a short primer on woodworking glues that should help shed some light on these types of questions.
There are several types of woodworking glue available for different types of projects. There are glues ready to use, those that need mixed with water and others that require two components to be mixed in order to activate the adhering qualities.
