How to use fiberglass filler for repairing imperfections

  1. Ensure both the filler and supplied cream hardener is at room temperature. Mix properly from top to bottom and knead hardener tube. Use 2% hardener by weight of the filler (or 50:1 ratio). Blend them together with rapid and forceful movements. Following the right proportion of hardener is essential to get desired results.
  2. Coat one side of the fiberglass cloth properly with the mixture and put it over the hole with the mixture side on top of the prepared surface. Use a spreader to flatten and smooth around edges to eliminate air bubbles and to promote adhesion.
  3. Use gentle pressure to press the center of the cloth to create a slight dip. Let some room be for the next coat of the filler mixture. Leave it for 10-15 minutes to cure.
  4. Prepare a mixture of additional filler and hardener as required to apply to the area along the original application's contours. 
  5. For finishing the repaired surface, sand for about 15-20 minutes, after which you can featheredge repaired area to desired contour.
