I am getting ready to build a mortar base for a shower. I'm pretty sure I know how to do it correctly except for one part I'm confused about - the slope. Most videos show a two layer mortar system and it seems that each layer is sloped 1/4 inch per foot. After the second layer of mortar is added you now essentially have 1/2 slope per foot if you add each sloped layer together. Is that the final goal? 1/2 slope? Or should the second layer of mortar be even in thickness since the first layer is already sloped 1/4 inch per foot?
Also seems like the rule is 1/4 inch slope per foot yet if this was followed all the way around the drain the mortar would not be even along the walls. It seems that the correct way is to make sure your longest runs are sloped at 1/4 inch THEN you keep the mortar even along the walls which essentially will make the shorter runs sloped more than 1/4 inch per foot. Can anyone clarify this?
