How to Cure Resin

Resin is used for many different purposes such as plastic molding and sealing wood. Resin can come in many different forms and colors, with each one made for specific applications. Resins are two-part liquids that require a catalyst to cure or harden. That catalyst used with resin is generally methyl ethyl ketone peroxide, which is a clear liquid. The amount of catalyst used depends on the temperature of the area in which you are working. If it's cold you will need more catalyst for the resin to cure.

Curing resin is simple to do.
  1. Pour the amount of resin you need in a small bucket.

  2. Add 1 to3 percent of the total resin in catalyst. Mix the catalyst thoroughly into the resin using a stir stick. Stir until the mixture becomes one consistent color.

  3. Apply the resin to the mold or application you are working with.

  4. Plug in a heat gun and begin to heat the resin up keeping the tip of the heat gun at least six inches from the resin. This will cause the resin to cure much faster than normal. Gradually heat the resin up so it doesn't get too hot or it will weaken the finished product and possibly discolor it.


  • The catalyst will leave a chemical burn on skin if it comes in contact with it.
