I have a screened in porch that currently has increasingly gross outdoor carpeting on it. A dog, two kids, a sandbox, spilled bubble-juice, and one end that gets soggy each time it rains has made it pretty gross out there. It's now beyond the help of a steam cleaner.
I was thinking of putting tile down out there. The subfloor is pressure treated 3/4 plywood. It feels structurally stiffer than the floors in the house, seems well built. I figured I'd put down cement board over the ply, mortar those joints, and put down some one foot square tiles with some texture to them to get traction when it's wet out there. Any recommendations along the lines of do it or don't do it, adhesive type, grout type, tile type? My biggest fear would be expansion and contraction with the seasons causing cracks since the subfloor's not in a climate controlled area.
Thanks, all.
