I just built my first laminate countertop yesterday and finished routing all the edges. Almost halfway through routing, my bit broke so I had to borrow a beveled trim router bit. This bit left a mess with the backer from the top sheet exposed on the top edge as shown in the picture. What should I use to clean up this edge, since all the laminate is on the surfaces now? Can I use a certain grit of sandpaper without damaging the laminate? Or is there a file that is fine enough? I am concerned because I will be scraping that residue off of the edge with the new laminate. It has the texture of cardboard, I think it's just the laminate backer. Thanks for any advice
This seems like a fine job for a razor scraper.
If not then a super sharp wood chisel would also work.
If using either tool you should be careful to not let the tool dig into the laminate. Make sure it's only slicing out the unwanted material.
Other thought: can you re-route it with a higher quality bit which won't leave behind such a mess?
