How to Heat Up Epoxy Glue

Epoxy glue is a reliable bonding agent commonly used in sealing cracks and making repairs. It works on wood, plastic, ceramic, glass and various other materials. Epoxy comes as two separate materials: One is a resin and the other is a hardener. Combining the two sets causes a chemical reaction that gives the glue its strength and durability. Epoxy often dries faster if it is heated while it cures, but the fumes are flammable so never use a flame to do this.

Popsicle stick or mixing stick
Disposable brush
Hairdryer

Instructions

- 1
  Mix the two epoxy components of resin and hardener, usually at a 1-to-1 ratio per manufacturer instructions. Place the epoxy onto an old plastic coffee can lid and stir with a mixing stick to combine the ingredients.
- 2
  Apply epoxy to the repair in accordance with your packaging instructions for best results. You will probably use a disposable brush.
- 3
  Plug in a hairdryer. Run it over the repair area as the epoxy dries to speed up the curing process. The heat shortens the drying time, and a hairdryer won't cause any fire risk with the glue.

  Inspect the glue every 30 seconds and apply the hairdryer again if necessary. Most epoxy glues are completely dry within an hour. Slow-curing epoxy can take up to 24 hours to cure.
