Applying Epoxy Filler Three

Scrape off as much excess as possible when using epoxy fillers. Once cured, they are very hard to sand. Fastidiousness in application will be time well spent.

These kinds of imperfections can be easily filled using a product such as Pettit EZ-Fair Its simple to mix parts A and B right on site.

For application, use either a plastic spreader or, our favorite, a modified putty knife. The putty knife ('"scraper," to some) has been customized. Its edge has been sharpened to a knife-like bevel so it deposits and removes material cleanly. And its corners have been rounded with a file to help avoid scratching and gouging. Combined with its flexibility, it makes a great tool for this kind of work.
