Ive finished my shower slope and had blu sealed it a couple of coats and was ready to tile with pebble moasics, but decided to check my slope so i threw a couple of buckets of water down the shower floor and discovered a couple of areas that dont drain. What do i do to fix this problem? Im really hoping i dont have to redo my entire slope. Thanks for any suggestions

Hi Ken
Just build it up with a good modified thinset. You might have to apply 2 coats to get it right.

Apply more blue seal just in case you scrape some of the existing layer while spreading mortar.
