Minor Fiberglass Crack & Abrasion Repair
Repairing ground out damage
If the damage is the result of a scrape or gouge, or cracks were exposed with a grinder, complete the repair as follows:
Open shallow and minor cracks with a “V”-shaped scraper, such as a sharpened can opener.
Grind out an area of many closely spaced or deep cracks with a disk grinder.
Minor cracks and scrapes that extend to the chopped strand mat layers of laminate may be repaired with WEST SYSTEM Epoxy.
Scraped out damage
After exposing the cracks using a “V” shaped scraper, complete the repair as follows:
- If cracks were exposed with a “V” shaped scraper, complete the repair as follows after preparing the damaged area as described above:
- Feather the edges with the scraper or with 100-grit sandpaper and brush the surface free of dust and loose material.
- Wet out the cracks with a 105 Resin/hardener mixture. Then fill the cracks with a 105 Resin/ 205 Hardener mixture thickened to the consistency of peanut butter with 406 Colloidal Silica Filler. Apply the mixture with the flat end of a mixing stick.
- Trowel the epoxy flush with the surface and remove excess epoxy before it begins to cure. Allow the epoxy to cure thoroughly.
- Sand the area smooth. Use 100-grit paper to remove any bumps or ridges. Finish by wet sanding with 220-grit.
Finish the area with gelcoat or paint.
Reinforce the laminate as necessary to reduce flexing.
