| '''Wood glues''' are [[adhesive]]s used to tightly bond pieces of [[wood]] together.

| | |
| Wood glue bonds tightly to wood, but not to itself. Therefore, [[woodworker]]s commonly use surprisingly little glue to hold large pieces of wood. Most wood glues need to be [[clamp (tool)|clamped]] while the glue dries to achieve maximum bond strength.

| ==Types of Wood Glue==
| |
| Many substances have been used as glues. The most common wood glue is [[polyvinyl acetate]] (PVA), also known as "carpenter's glue" or "Yellow glue". The white version of polyvinyl acetate is also used on wood. Traditionally, [[animal glue]]s were ubiquitous, especially [[hide glue]], which is still used in [[lutherie]] and restoration. [[Polyurethane]] glue (trade names include ''Gorilla Glue'' and ''Excel'') is becoming increasingly popular, especially where water resistance is required, although water-resistant PVAs are available .
| |
| | |
| Substances used as wood glue include:
| |
| * [[polyvinyl acetate]] (PVA), yellow & white
| |
| * [[animal glues]]
| |
| * [[Polyurethane]]
| |
| * [[Cyanoacrylate]] (''Crazy glue'' or '''Superglue''') used mainly for small repairs, especially by [[Woodturning|woodturners]];
| |
| * [[contact cement]] for [[Wood veneer|veneers]];
| |
| * [[Hot glue|hot melt]] for temporary uses;
| |
| * [[Epoxy]] mainly for exterior uses;
| |
| * other synthetic [[resin]]s including [[resorcinol]], [[urea-formaldehyde]], [[phenol formaldehyde resin]], etc.
| |
| | |
| | |
| ==Exterior Use==
| |
| Wood glues intended for exterior use vary in their suceptibility to water.
| |
| * [[PVA (exterior grade)]]
| |
| * [[Polyurethane]] - survives showers but not constant wetness
| |
| * [[Hide glue]]
| |
| * [[Cyanoacrylate]]
| |
| * [[Contact cement]]
| |
| * [[Hot glue|Hot melt]]
| |
| * [[Epoxy]] - waterproof
| |
| * [[Resorcinol]]
| |
| * [[Urea-formaldehyde]]
| |
| * [[Phenol formaldehyde resin]]
| |
| | |
| | |
| ==Trade & other names==
| |
| * [[PVA, yellow]] - carpenter's glue, yellow glue
| |
| * [[PVA, white]] - elmer's, white glue,
| |
| * [[Polyurethane]] - Deckbond, Gorilla Glue, Excel
| |
| * [[Hide glue]] - animal glue,
| |
| * [[Cyanoacrylate]] - Superglue, crazy glue
| |
| * [[Contact cement]]
| |
| * [[Hot glue|Hot melt]]
| |
| * [[Epoxy]]
| |
| * [[Resorcinol]]
| |
| * [[Urea-formaldehyde]]
| |
| * [[Phenol formaldehyde resin]]
