How to use fiberglass filler for repairing imperfections
- 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.
- 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.
- 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.
- Prepare a mixture of additional filler and hardener as required to apply to the area along the original application's contours. For finishing the repaired surface, sand for about 15-20 minutes, after which you can featheredge repaired area to desired contour.
