How to Use a Polyester Adhesive

Save

Polyester adhesives are most often used to glue fiberglass. The adhesive dries quickly, is waterproof and forms a rigid bond between surfaces. Although it takes more preparation time than many other adhesives, the end result is worth the time.

Things You'll Need

  • Polyester adhesive
  • Adhesive activator
  • Application tool
  • Examine the surfaces you will be gluing together. For the polyester adhesive to work best, the surfaces should be clean and as smooth as possible.

  • Prepare your adhesive. This is done best by following the instructions on the label of the product, although most are prepared in the same fashion. Most are mixed with an "activator" to activate the adhesive.

  • Apply the polyester adhesive, using a brush or a stick. The glue should be applied until the surface is covered (or filled, if you're using the adhesive to fill a hole or dent).

  • Wait until the adhesive is completely dry before using the object. This is particularly important if the adhesive has been applied to a boat or other device that you will put into the water. The glue must be completely dry before it is waterproof.

  • Apply acetone to the glued joint if you wish to remove the bond. Acetone is found in some nail polish removers which can be found in any grocery store.

Tips & Warnings

  • Drying times vary with different polyester adhesive brands and formulas. Check the instructions and follow them carefully. You can use polyester adhesive for projects when you want to avoid the dripping and running of normal glue. The viscous quality of polyester adhesives lends them more stability.
  • As with all glues and adhesives, be careful not to get polyester adhesive onto unwanted objects. To prevent this, cover your workspace with newspaper.
