A mainstay of building material for thousands of years, granite continues in popularity as a design element in the 21st century, with types of tiling options and other installations. The variety granite tile offers in different sizes for floors, walls, stair treads and entryways of buildings and homes makes this natural building material useful and practical as well as a beautiful decorating element.

Textures and Finishes
Polished finishes bring out the color and other natural elements of the different kinds of granite tile, while honing does the same with less shine. Leathering provides a textured matte surface to granite tile and works well on darker shades. Antiquing makes the tile appear old and rustic but is not advised in high-traffic areas or areas with significant exposure to heat and moisture. Brushed or flamed surfaces of granite tiles are yet other textures used as an accent in decorating.

Porosity
Absolute black is the most nonporous type of granite tile and is popular for countertops in both kitchens and baths. Because all granite is nonetheless porous, sealing it on a yearly basis assures that the tiles do not stain. Sealing also keeps the tile shining and durable.

Edging
Some types of granite tile can be identified by their edging. Bullnose (rounded edge) tiles are used for the top row on a tiled wall. Beveled edges on granite tile provide an "in view" look, as the beveling opens the tile outward at the edge. Cleft-stone edging brings out a roughened finish that a saw cut edge would not.

Specific Applications
Choosing the correct type of tile for particular uses assures satisfactory results. Polished tiles work well as indoor flooring in low-traffic areas and for vanities and countertops. The polish makes them slippery to walk on. Honed surface tiles work best in high-traffic areas both indoors and outdoors. The most outdoor versatility comes with brushed or flamed granite tiles for use on decks, sidewalks and decking, as well as in tiling a garden bench.
