Install the tile. A bullnose edge should be ground down after the tile is installed and set firmly.
Mark the tile. Begin marking the edge of the tile at the 45-degree angle you'd like. Mark the edge and the top and side to note where you'd like the bullnose edge to start and stop.
Begin grinding. First use low-grit pads. Grind the travertine corner down to the 45-degree angle you've marked. Move along the entire edge and grind to the 45-degree angle all along.
Curve the edges. Use the higher-grit grinder disks to curve the angles. An 80 to 120 grit will remove the stone slowly enough to control the curve. After the curve is formed, use 240 grit to remove scratches and 400 grit to shine the stone.
Wash the stone. Using a solution of muriatic acid and water in a 1:10 ratio, wash the edge to give the bullnose the same honed look as the flat portions of the stone.
Things You Will Need
- Safety glasses
- Mask or respirator
