 One of the best materials to use is porcelain because it is non-porous and a very high density tile. It also comes in a variety of colors and patterns to suit your individual taste.

Once the tiles are in place and grouted, wait a week and seal the grout for a long-lasting and very impressive porch. I'm Danny Lipford with tips for today's homeowner.
