Do you need to use RedGard over cement board?
No, you don’t need to apply Redgard over your Hardibacker. Here’s why: Redgard works best on cement boards and plywood because it prevents water from seeping into those surfaces. It can also work on top of drywall that isn’t behind a tub or shower, but it will eventually wear off after repeated moisture exposure.
How many coats of RedGard can I put on?
When dry, apply at least one full coat of RedGard® to the primed area. When used as a vapor barrier, apply one full coat (20 to 25 mils wet) where vapor transmission is up to 8 lbs per 1000 sq. ft per day and two full coats (20 to 25 mils wet each coat) where vapor transmission is up to 12 lbs per 1000 sq. ft per day.
Do you put RedGard on shower floor?

What is a disadvantage with sheet membranes?
A higher in-place cost is one of the main disadvantages of sheets. The cost of the material itself is likely to be greater on a square-foot basis than the liquid membranes. Labor cost is also higher, because of all the cutting, handling, reinforcing, and detailing you have to go through during installation.
