The steps to apply the rubber repair system, Belzona 2221 (MP Fluid Elastomer), are as follows: Clean the application area with Belzona 9111 (Cleaner/ Degreaser). If oil continues to form, abrade the surface with a suitable roughing tool. Apply a thin, even coat of Belzona 2911 (Elastomer QD Conditioner) or Belzona 2921 (Elastomer GP Conditioner) onto the surface with a brush. Empty the entire contents of the Base and Solidifier containers into the mixing bowl provided and mix for at least 2 minutes until the material is an even consistency and color. Apply the Belzona 2221 (MP Fluid Elastomer) to the prepared surface with a stiff bristle brush. Or the plastic applicator provided. Allow to cure.
