Question

Durock or Green Board


Hello, I have a question. I am remodling my shower/Bathroom and was going to tile the that I had just installed. Anyway, I had installed Durock on the back wall so far but it doesnt quite reach where I wanted to stop tileing (12"short). I was woundering if I could use green board instead of adding more durock to make up the diference of the 12" since im using green board above the window anyway? Or should I add the durock?


Thanks!

Should I assume you meant tub surround?

If so....(here I go again )

What about waterproofing? Tile and grout are not impermeable to water. Durock is NOT waterproofing. If you don't waterproof, mold or tile failure is in your future. A quick fix to your situation is to buy some RedGard. It is a liquid membrane that you paint over what you are going to tile. In this case, you would be able to finish your walls with wall board and just paint the RedGard over it. Problem solved.

Also, greenboard is an old, outdated material. It has no benefit. If you want a material that's useful, try DensArmor. It's mold resistant.

Good luck

Simple answer to the question: Tile will stick to any kind of sheetrock. If you have an area that will be directly affected, or is directly adjacent to, a shower, or high moisture area, I suggest that you use a cementitious board for your tile work.

As covered by Angus: MR (aka green board) is a product that is rated as Moisture (vapor) resistant. It is not moisture (direct water contact) resistant. It is also a very old and outdated product that has been superceded by much more advanced wallboard materials such as Densarmor (paperless and truly mold resistant wallboard) or XP board (the new paper-faced MR board - purple, mold resistant paper - with a mold resistant core)

I do not suggest that either of these be used as a tile substrate surface, in wet applications (shower area/tub wall). However, the material is practical in it's use in other areas of a bathroom or in basement remodeling (finishing) projects.

Yes, by all means, Durock is your PREFERRED backer. However, for the last few inches of your wall, IF and only IF you use RedGard, you'll be OK. If you can get Durock up there, use that.

Don't just "look into that RedGard stuff". BUY IT! It is usually sold at Home Depot.

Waterproof your surround and be done with it! RedGard is made to be tiled over.

Good luck
