What is 3M Woodworking 20 Spray Adhesive?

3M Woodworking 20 Spray Adhesive is a general-purpose adhesive that is ideal for woodworking projects. It is made of high-strength bond that allows you to glue wood to wood, metal, plastic, and other materials. 3M Woodworking 20 Spray Adhesive is particularly useful for irregular surfaces, where precise glue application is difficult. Best of all, it dries clear, which makes it perfect for attaching panels that need to be seen or painted over.

How to use 3M Woodworking 20 Spray Adhesive

3M Woodworking 20 Spray Adhesive comes in a handy can that has a spray nozzle for easy application. Here is a step-by-step guide on how to use it:

  • Step 1: Prepare your workspace by ensuring that the surfaces you want to join are clean and free of debris.
  • Step 2: Shake the can thoroughly to mix the adhesive.
  • Step 3: Hold the can 8-10 inches away from the surface and apply a thin, even coat.
  • Step 4: Repeat the same process on the other surface you intend to join together.
  • Step 5: Wait for a few seconds to allow the adhesive to become tacky. You can then join the two surfaces and apply pressure for a firm hold. Be very careful when joining surfaces together since the adhesive sets fast, usually in 15-30 seconds.
  • Step 6: Leave the joined surfaces to dry completely for 1-2 hours before painting or sanding them down.
