Someone put in green board, then cement backer board, then tile. What I want to do is copy that, put in green board, (then add a waterproof selfadhesive membrane on top of green board), then the cement backer board, then tile.
Is this a good method or what are potential problems with that. Reason I want to use the green board is to provide support and additional water proofing for the selfadhesive membrane I am going to apply everywhere in the shower.
Can you help me out? Thanks.
I use Dens-Armor Plus sheetrock behind my showers and tubs. Then use Schluter-Kerdi mat as my water proofing membrane. http://www.schluter.com/8_1_kerdi.aspx I ...»
Is there anything wrong with doing that? Codes, etc. Thanks.
I had a few sheets of this left over from a job and had it next to my shop for a long time. ...»
The only thing I hate about it is you must wear long sleeve shirts when handling it as you end up with tiny welts as though you have been putting in fiberglass insulation all day.
Anyways, another reason I am doing this, is I ordered too much membrane for my outdoors, so I figured I'd use it in my shower, and stick it to the green board, then build my waterproofing layout with durarock from that.
Yes it can be damaged on the edges, just like any sheet rock material can. But as you noted, woodbridge, it is impervious to the elements. If I remember correctly it has a five year warranty when it is exposed to the elements against any type of moisture damage or fungi growth. Every ...»
David, I used the Dens material in my bath with two layers of half inch wonder board. I used two layers to get the face of the second one to overlap the tub lip and create a void making it impossible for water to go up two inches and get behind the wall, and even if it did the floor is sealed and the Dens material is there to greet it in that unlikely possibility. It may not be necessary to take extra precautions but if you want to, and know how to do it, and can afford it, it certainly can't hurt to have as many layers of protection as you feel comfortable with.
You have a few correct options for doing the tub/shower area. Use cement board over a plastic vapor barrier. Then tile, ...»
Or use any kind of wall material green board, or cement board or Dens Armor sheet rock then cover it with a water proofing membrane such as the Kerdi. Any other method is simply a gamble with products that are not typically used for this type of job and its anybodies guess if it will work or fail. And doing this type of job which as you already know is a lot of work only to find out in short order that you may need to tear it all out and start again.
For my project the best solution is green board, membrane, durarock, tile. If I had to design the show from scratch, I would probably do membrane only, then durarock.
Thanks for the ideas.
Thanks for your input.

I hope this helps. Sometimes you have to get away from Lowes or Home Depot to get something better.
Last year we reinsulated our house and I was knocked off my feet at the cost of insulation. I checked with our local supply company, Capitol Materials, and they had the same insulation, brand and all, as Lowes but it was half the cost. A little digging can pay off big when you are doing a project. Good luck.
