Porcelain tile on our porch - pics!

| We installed Porcelain tile on our outside covered porch. It is over the garage and basement area - so it had to be sealed.
Previously the owners of this house had an indoor / outdoor carpet down, with an asphalt / rubber membrane under it - it didnt work - it was rotted and loaded with carpenter ants - real fun..
So we stripped it, re-sheeted with 3/4 ply, used 1/2" durock sheet taped w/ fiberglass tape, used a thinset specified for outdoors, and used a porcelain tile. The grout was also spec'd to be indoor / outdoor.... We sealed with bathroom style sealer for heavy water...
Bummer is - there is a low spot where water sits due to the fall of the porch..... in this spot, a tile popped loose.. I broke the tile out and it was soaked underneath, and water ran under the tile next to it because of the direction of the grooves in the thinset...
So, the tile next to it is wet underneath, and if I step on it I can squeeze water out....
Question:
1.) Should I also replace that tile?
2.) Should I be concerned with this whole thing?? It was a ton of money and a ton of work!!
3.) How warm does it have to be to re-apply new thinset and another tile?
Pics below... Nice ants?
Help!!
Thanks!!

| MB,you actually did something I have only talked about over here but always wanted to try. It looks like they did pretty much what I was thinking, seam tape the joints, with fiber glass tape? thats what it looks like in the yellow rolls.They fixed the frame I am thinking. My idea was to tape/bed the plywood as well, just about anything to keep movement from happening. You have a roof under all that as well,intersting project. I was also going to install the tile with high grade construction adhesive you might try this if just one area is low. That adhesive is real heavey bodied stuff and might make up for a little dip.

| Actually we did all the work ourselves with some help from friends - this is all part of a kitchen and dinning room remodel. Yes we used fiberglass tape.... Good idea on the adhesive - we may try that on these tiles that are popping up. Incidentally today I am putting down dura rock in the kitchen and dining room. I am typing with ripped open knuckles from trimming durarock, and also with thinset all over my fingers now on my keyboard :) I am burnt out - this project is wearing me thin. One thing I am doing in the kitchen and dining room that i didnt to on the porch is to thinset both sides of the durarock for more stability. |

| We have an enclosed sun room (Florida room) which we tiled with porcelain tiles. Former owners used marine grass/carpet over concrete to hide the leaks coming from the roof and walls (long story). Needless to say, we gutted the room, and tiled the floors. Since this room isn't heated and is pretty much a screened-in patio area we used a thinset approved for outdoors. We had to use alot of bags of it too because the concrete flooring was uneven and we had to grade it away from the house in case the roof and/or walls leaked again. In the end, I think the generous amount of thinset also helped the tiles to stick better. So far so good. I would post before/after photos, but I don't know how to attach them. |

Tiles that pop up are an indication of a problem. Especially if you just put them down. I would hold off on any other tile projects until you understand what you are doing. Floor deflection, methodology of the substrate attachment and thickness, bonding cementboard to plywood and trowel notch depth are all part of the job. Failure in any one of these categories can doom the floor.
In reading over your post, you failed to do at least one of them correctly. Eventually, the tiles will loosen and the tiles themselves will begin to crack.

| mbx I am glas I came across your post. Our GC wants us to tile the floor under our covered porch. I wanted pavers & bluestone but he says it will be too much weight. My husband is hesitant since he cannot picture it in his mind. Now I can show him your pics. My only concern is what did you do on the end tiles who edges are exposed (under the railings). Is there some sort of tile with one edge finished or do you gut use some type of capping? Thanks Noreen |
