John, Of course I used the Kerdi screws and washers. Made patches big enough to cover 2 inches on ever side of the washer/screw combo. Unmodified thinset as required. Banded well over the required 2". Not being very clean with my kerdi install of course there was a lot of exposed thinset. So the next day I used a damp sponge and water and cleaned up the surface thinset. Noticed I got a defective ( old delaminated kerdi band) batch of kerdi band so ripped off the two pieces I made off of that band. Cleaned the thinset off and went in with a new roll of good kerdi band. I don't know how people clean the kerdi band when the thinset is wet ( still a mess). Used kerdi fix just on the outside surface of the seams like a caulk almost. I have a neo angled shower so I had to use it on the two 45 degree corners (why kerdi does'nt make a 45 degree corner I have no idea. Tested my plug the other day and it leaked or the water evaporated. I am going to say evaporated because I made a tiny kerdi tub and put water in it to test the waterproof membrane just for fun and that was all evaporated in less than a day also. Removed the plug and made sure nothing was stopping my seal. Once again I am just using the small red test plug with wing nut on top. tested it for a hour and no water drop. Commenced flood testing. stacked coins (Its a crap load of coins). It wicked higher than I would have liked but it seems it is only where there is thinset left on the membrane. I can see spots that I did not touch that look like dry membrane under water and then I can see spots where I set my water bucket on the membrane to clean the other day. You can actually see the imprint of the bottom of the bucket. I can see the drain flange but could see that before so no surpise ( yes I used kerdi fix to seal the lip around the drain also) Wicking in the sides some wicks none and some up to the top of the curb then stops. Over a 12 hour period I got a water drop of half a pennies width. Probably evaporation or the drain plug leaking a little over that time. Topped it off with about 14 oz of water and we will see what happens next. I plan on leaving the test for probably 72 hours. Also luckily the rest of the bathroom floor isnt sealed so I can crawl under and inspect for leaks. Since I did quiet a bit of scrubbing on the membrane ( nothing that messed anything up) and water has been on it before I'm not concerned with the discoloring as I know it isn't water getting under. The wicking happened even with the damp rag and water I spilled while washing away excessive thinset. Just wondering your thoughts? And Ardex here in california would be almost impossible to get.
