Redgard Vs Kerdi Membrane

What did we do wrong.

Redgard vs kerdi membrane. Kerdi vs redgard for tiled shower ive been reading the john bridge forum etc but am curious if anyone here has done a tiled shower and been especially happy with the process. Kerdi on the floor and red guard on the walls question the floor is concrete and it is an existing shower that i will be tearing out. Whether or not you need a kerdi membrane is a factor of use. Kerdi really offers very little advantage over hardiboard plus membrane.

Paint the inside with redgard 2 coats per instructions. I followed instructions but somehow we must of missed a step because everything cracked and water would have poured right through. Did we use too. Fill the box with water and let sit forever.

For 3 weeks it soaked in water and remains water. If you do that there is no difference in the final product from kerdi noble redgard hydroban mer krete or any other type of membrane you use. I layed it over an existing slab with moisture and crack problems about a year ago and have not had 1 problem. I use it mostly on shower walls.

Hello i am looking for the best liquid waterproofing membrane over durock cement board in a regular shower not a steam shower and the products my looking at are hydro ban redguard and durock has a fairly new product they have now usg durock liquid membrane the hydro ban is the only one that has to be used with their sheet membrane if used for steam shower applicationdoes that make hydro. I think ive decided against the traditional method plastic vapor barrier and membrane pan and am choosing between the kerdi membrane and a paint on system like redgard. The valves typically have a gasket behind them and if your tilework is decent will prevent any moisture from doing anything. The person that did it fifteen years ago just tiled over the existing concrete floor so i was going to do a dry pack job on the floor and use a kerdi drain.

If it leaks you didnt apply it correctly the trick is to not have pinholes. Backerboard plus a waterproofing membrane like redgard is all that is needed for tub surrounds with thinset then tile. In normal residential use i wouldnt worry about it. Redguard vs schluter ditra although detra and redguard are fine products i personally was directed to a sheet applied crack isolation product called ecb membrane by nac products.

Build yourself a square box out of hardibacker or similar. A shower head is so high the eschution would likely block any issues. Visions of a second story leak on to a high dollar baby grand pianoas with anything you need to have confidence in yourself as an installer to follow the directions correctly and achieve the proper mil thickness in 3 4 coats. But since redgard is designed to enable thinset to bond to it and the kerdi fleece bonds with thinset it should work.

Waterproofing is waterproofing if your product works then the thing you use it on doesnt matter.
