Cracks and Scratches
Typically located in vulnerable areas such as exposed corners and coamings, or in areas susceptible to flexing or stress.
Solution 2 - Repairing minor cracks & scratches
1. Remove loose or damaged material. Open cracks with a sharp, 'V' shaped tool, scraping down to the bottom of the crack. Dry out the damaged area if necessary. Feather the edges with a scraping tool or 100-grit sandpaper.
2. Apply enough epoxy mixture to thoroughly wet-out the damaged cavity.
3. Blend a 413 Microfibre Blend with the remaining epoxy mixture to make a thick, non-sagging mixture. Trowel the mixture into the pre-wet cavity.
4. Allow to cure about 24 hours at minimum 25°C.
5. Sand to shape before painting. Use 80-grit sandpaper to level any ridges or bumps if necessary. Wet sand fair with 220-grit paper. For high gloss finishes, continue wet sanding down to 400-grit.
Gelcoat or a two part polyurethane paint both provide the ultraviolet protection required for epoxy. Marine-grade enamels work well on interior surfaces. Follow the paint manufacturer's recommendations for final preparation and application.
