Schluter Kerdi shows ridges through Kerdi...

I wish I would have found this site last thursday. I have installed two walls of kerdi using hardibacker, Mapei Floor and wall tile mortar, a 1/4 x 3/16th V-notch trowel, and I can see ridges through the Kerdi all over the walls. I mixed the mortar to a milkshake consistency by adding more water, I used two trowels to embed the Kerdi in the Mortar but it just would not flatten out. I did not do the pan yet as I am afraid I need to tear it out and do it again, but I don't know what to do. I have a call in to Schluter but since its the weekend, they can't get back to me until next week. What should I do?

Welcome to the forums! I don't get to do much with the Schluter system, mainly for cost vs. clientele penny watching. SO, the tile pros will chime in here shortly, but I don't see a real problem with the surface of the kerdi. You will be setting your tile in 1/4" base, so any minor aberrations won't matter much. Normally the kerdi and ditra are patted out with a rubber or wooden float to maintain smoothness. Did you use that? Or did you just keep troweling?

Thanks for the reply. no float or mallet. I kept troweling. The only thing I am worried about is the tile falling off of the Kerdi. The seams turned out great.

I'm no expert, but I too have used the Kerdi and the little mud ridges behind the Kerdi were visible through the material. I found that the Kerdi was well and truly fixed to the substrate, so no worries at all!
