Marble tiles have a natural beauty that can enhance any area of the home. However, polished marble tiles, with their straight cut edges, may not always lend themselves to wall applications, as the sharp edge can be left exposed. Therefore, for applications such as bathroom shower walls or kitchen backsplashes, a bullnose tile is needed. The edge of a marble tile can be ground down and polished to approximate a bullnosed tile. Putting a polished edge on a marble tile allows polished marble to be used in wall applications and appear completely finished.

Change the blade of the wet saw to a bullnose blade. The bullnose blade will help to remove the bulk of the tile from the edge, rounding out the tile.
Place the tile on the wet saw, with the edge to be bullnosed fitted so that when the tile is pushed forward, the edge will fit into the notched groove of the bullnose blade.
Push the tile back and forth on the wet saw, with the edge of the tile to be polished pressed tightly against the side of the wet saw bullnose blade. This will remove the bulk of the edge and round over the side of the tile.
Install a polishing pad onto the end of an angle grinder. Holding the angle grinder to the edge that has been rounded, pass the grinder both along the edge lengthwise and over the top of the edge. This will even out the edge and give the marble a high sheen. Move the grinder continuously when in contact with the stone; do not allow the grinder to remain in one place or this will etch the stone.
Paint the finished edge of the marble with a shine-enhancing marble sealer using a foam paint brush. Allow the sealer to soak into the edge of the marble for several minutes, then buff the edge with a white, lint free cloth.
Tips and warnings
- Practice putting the edge on scrap pieces of marble before attempting to put the edge on a piece of marble ready for installation.
- Use a variable speed angle grinder and test it on a scrap of stone first; some marbles are softer than others and will grind down faster. For these softer stones, use a lower speed.
