Polishing a Bullnose Edge on a Granite Countertop
By: Danny Lipford
I had new granite installed in my bathroom and the bullnose edge is dull. The granite installers told me it’s just the way some granite species are. Is this true? – Gary
While it’s true that granite can occasionally have a dull vein here or there, the fact that the top is polished means the edge can be just as shiny. With a bullnose edge molding, though, a little extra time and effort has to be taken to get it right.
The rounded edge on the bullnose trim makes getting a uniform finish more difficult, since the angle grinder used to polish it has to be rotated to produce an even surface. Make sure your granite installers progress slowly from coarse to very fine grit on the sanding pads in the following sequence: 50 grit, 100 grit, 200 grit, 400 grit, 800 grit, 1500 grit, 3000 grit.
If they won’t do the added work it takes to polish the granite bullnose right, have another professional stone finisher tackle the job, and deduct the cost from the installer’s invoice!
Good luck with your project,
