Exterior Porcelain Floor Tile
 
I am looking into laying porcelain tile down on our covered front porch (10 x 20) and possibly the back covered porch as well (14 x 34 which will likely be enclosed later).

We live in a fairly remote area 180+ miles from Boise, Idaho and have been looking on line at: Home Depot Eliane Tile, Lowes Surface Source Tile, and Daltile - Cliff Pointe Tile

What we are after is a porcelain tile that is textured, has a high durability index / PEI rating and a COF of no less than 0.60.

Our questions are how important is:

1) tile thickness, say between 3/16 and 5/16
2) break strength, say 250 vs. 350
3) textured vs. smooth with similar PEI and COF

Porcelain on an exterior slab
 
You're in an area that freezes so porcelain is the way to go, however, I suggest not skimping on the quality of the thin set you will be using. Do not purchase the cheapest kind, due to the fact that a lot of thin sets don't have the polymers to mechanically and chemically bond to porcelain, which is vitreous, like glass.

That being said, if your concrete doesn't have a lot of moisture coming up through it from the ground, porcelain would be the only choice.

Consult the tile shops and floor covering shops. Their selections will be far greater than the big boxes and they aren't in the business of selling off goods or drops. Their expertise is far better than what you get in a box store plus their service and maybe surprisingly to most consumers, their prices are competitive. As a DIY'er, cash and carry will always dictate to the dealer that he can take a shorter mark on the sale because he has no responsibility in the installation of the product, but he's always there for advice.:thumbup:

PEI is all you need to worry about. ADA requirements require a .6 wet and dry. It's a safety requirement for slip resistance. PEI is relating to the hardness of the tile. No worries. It's porcelain in a residential setting. Breaking strength is nothing to worry about.

Stay with 5/16. You usually don't buy tile by thickness and the thickness usually isn't posted anywhere. Quality tiles will be a minimum of 5/16".

Have no idea what you are talking about...do you?
Tile isn't usually sold posting "break strength", what the heck does that mean anyway?

Here again...where on earth are you getting your information?
PEI has absolutely nothing to do with C.O.F.
The number you refer to (0.60) may have something to do with C.O.F. but has absolutely no meaning when it comes to PEI.

Excuse me Bud
 
I meant COF. It's late, dude. He doesn't have to worry about the PEI rating.

sheet it with 3/4" ply, 1/2" durock sheet taped w/ fiberglass tape, used a thinset specified for outdoors, to use porcelain tile The grout needs to be spec'd to be indoor / outdoor.... seal with bathroom style sealer.

Doesn't matter the size tile used the new textured tiles that are out are fine.

:blink::blink::blink::blink: Call me confused.

What is the surface of your porch? I would be just as concerned, if not more, with having a proper foundation.
