Glue is one of the most important materials used when assembling projects. The success of a completed project often depends on knowing which glue to use for a specific application.

There are three basic glue categories (figure A). White glue is good for woodworking and can be used for a variety of projects in the shop. Yellow glue has resins incorporated into glue to enhance the bond and provide moisture protection. Polyurethane glue bonds pieces together. It will also fill in small gaps, improving moisture protection.

Tips for Using Glue:

Yellow Glue

• When gluing two pieces together, a little squeeze-out is okay. Too much squeeze-out indicates that you have used too much glue.

  
  

• Scraping squeeze-out (figure B) can damage wood.

  
  

• Clean as you go to reduce scraping.

  
  

• Smear the glue around to ensure adequate distribution, and then clamp in place to secure.

  
  

• Use a damp sponge to clean glue away (figure C), before it has dried.

Polyurethane Glue

• Polyurethane foams up as it dries and can be difficult to remove.

  
  

• Apply a thin line of glue while holding the applicator upright.

  
  

• Squeeze-out should be avoided.

  
  

• To reduce drying time, pre-treat the surface with a small amount of water.

  
  

• Polyurethane glues use moisture to help with the bonding process.
