Shower Slope Question
We are preparing to put Kerdi on our shower floor. I flooded the floor with water. Most of the water drains correctly but I noticed a few low spots where water is pooling slightly near the drain and next to the curb. I believe that the floor was sloped correctly at 1/4" per foot. I'm wondering what should be done to correct this. Should we add thinset to the low spots and let them cure before doing the Kerdi or just fill in with thinset during the process of imbedding the Kerdi? Definitely don't want to have problems with the floor not draining after the tile is installed.
Also, the floor can only be accessed from one side. Is it all right to put the thinset on the back half of the floor first, imbed the Kerdi, then do the other half of the floor? One piece of Kerdi will cover the whole floor. Thanks for any advice.
