Instructions

  • This is a brush-on epoxy coating for EPS foam and other surfaces. 
  • Ensure the surface is clean, dry, and free of dust or grease before application. 
  • Mix 100 parts Part A with 20 parts Part B by weight, blending thoroughly until uniform. 
  • Apply with a disposable brush in thin, even coats. The thixotropic formula allows use on vertical and overhead surfaces without sagging.
  • Working time is approximately 15 minutes with 101 Fast hardener (longer with 101 Slow). 
  • Additional coats or reinforcement fabric may be applied once the previous layer becomes tack-free. 
  • It reaches handling strength in about 16 hours and cures to a hard, moisture-resistant shell that can be sanded, drilled, carved, painted, or laminated.
  • Use gloves, eye protection, and adequate ventilation during use.
