Right up your alley, Hammy. Imagine what you could do in a kitchen with this stuff. Kitchen counters will be my next project once I get the bathroom finished.

Thin set test

Did a little Kerdi application in my shower today. Also glued some scrap together. Glued a couple sets factory edge to factory edge, i.e., foam to foam. I'll pry a little on one of them tomorrow and let the other cure for a week or so. Also glued a scrap foam edge to board face. It's such a small piece it'll probably pull the vapor barrier off, but we'll see. I didn't have any Ditra-set, so I used VersaBond.

Also talked to Peter today about fasteners. He did use fasteners, but his application is a little different than mine. He used kerdi fix on the studs that were bowed outward but attached the board with fasteners to the studs which allowed the board to lay flat.

My wall was leaning in about a half inch at the top, so I had no studs that would allow the board to remain flat yet plumb. So I used Kerdi-fix totally to fasten the board to the studs with only enough screws to hold it in place while the glue set.

The fasters are exactly like the Wedi fasteners which feature flat washers. They are currently made in Germany. I'll be getting some forthwith so I can try them out.

Peter and I agree that my method will work. I've got so much Kerdi-fix on the studs that fasteners aren't needed. That board ain't coming down tile or no tile.

How many tubes of kerdi-fix are you going to use to do the shower you are working on?

Geez JB,

With all the talk of crooked studs, sounds like a mud job would just be perfect!

John,

When you cut your Kerdiboard in strips to make the bend I assume you will need to
Kerdi it again since you broke through the factory applied membrane...correct ?

I originally ordered 8 tubes of Kerdi-fix. Figured that would be plenty. Didn't know my walls were so bad. Anyway, I got about 2/3 of the walls up and the shower 90 percent built with the eight tubes. I've since ordered and received 10 more tubes. And CX is right. I wouldn't want to pay for all that glue at about $22 a pop.

Went out this morning and broke one of the foam-to-foam samples apart. Didn't take too much force. The thin set broke clean from one piece of foam. I don't understand that because you can't pry it off the other piece. The only thing I can think of is that I didn't get it burned into both pieces equally. Or possibly, one surface was somehow contaminated. I'll welcome ideas. Of course, the folks at Custom would tell us not to pry on things after only 12 hours of curing, and they'd be right.

I'll let the other two samples linger for a week or so, and the next time I mix a batch of thin set I'll glue up a couple more samples making damn sure I burn everything in.

First pic shows mortar breaking clean from one of the surfaces but adhered to the other.

Second pic: I tried to gouge the thin set in order to break it free to no avail.

Third pic: Enhanced version of the previous. By changing the gamma adjustment I brought out the gouge marks a little.

At this point I think we've proved that it is possible, though, to bond Kerdi-board to Kerdi-board foam-to-foam with thin set mortar.

Sorry, Forgot to answer Brian's question about re-Kerdiing the curved wall.

When you kerf through one side of the board to allow it to bend, and that side needs to be waterproof, you must Kerdi it, which is what I did yesterday. I first filled the kerfs so that when the mud sets up the wall will be stiffened. This is a free-standing wall with no attachment to the ceiling.

The end of the wall had quite a bit of slop until I performed this process. When I checked it this morning all but about a quarter-inch of top movement had been eliminated. I'm going to depend on tile and grout on both sides of the wall to provide the rest of the stiffness.

Remember, now, we're treading virgin territory on a lot of this stuff. I don't think anyone has done it before with Kerdi-board. Looks like it's going to work, though. I know it would be impossible to build such a wall with wood framing or even with metal studs.

P.S. If the cut side of the board doesn't need to be waterproof I think it would be enough to simply fill the open kerfs with thin set. We'll know more on that when I complete my thin set tests. The mud would have to be fully bonded to all the exposed foam surfaces.

Mud Jobs

Also forgot about Matt's comment about using mud. As you probably know, I'm a mud man from way back, and along with Davy and a few others around here I agree it's the best way to get things straight, flat, plumb and level. I started doing mud in 1973. It's a solid system.

But it's not the best . . .

Mud showers wick just like backerboard showers. Mud shower floors become cesspools just like backer board showers. The best shower is one that's straight, flat, plumb and level, and that doesn't leak into the substrate be it floor or walls. I've been doing those showers for the past six years or so. Kerdi-board is just another step in Schluter's progression into the future. I truly find it hard to say after all these years, but although mud work still has its place without doubt, it just isn't going to find its way into showers too much longer.

8 Days Later

Broke my samples made eight days ago. Still have the thin set separating from one piece pretty much, which may or may not be normal. I think I failed to burn it into one side because you can't pry it off the other piece.

The sample glued head-on to the fleece tore same off when it broke. Took some good force to do that, and I have no doubt it's possible to glue Kerdi-board together with thin set. I think you just have to be careful to burn it in.
