How to pick water resistant drywall

At Expert Drywall USA, we are here today to talk to you about moisture resistant and mold resistant drywall or walls in general. If you have been following our drywall blog, you will have noticed that we talked about some washers we worked on and the way we chose mold resistant drywall for most of our work. For us, that is kind of minimum standard that we use on a daily basis. Just to clarify in greater detail, minimum standard is actually just using backer boards in the shower area finishing the drywall off everywhere else. But we like to just step it up that one step higher where we are doing the full washroom in the mold resistant board.

Now, when you are doing something like a steam shower like what we have covered in one of our previous blog posts, you are not going to be able just to use a mold resistant board. You need a membrane or something between there that will keep the moisture from getting in behind. So, what we want to do is just chat with you a little bit about this topic to bring to your attention that when you are doing some of these different products that you must make sure that you are using the right type of moisture resistant board behind your tile to ensure that your shower never gets mold in behind it. This is just something to think about that moist areas are a lot different than areas that are in a house that are like a bedroom with really good ventilation.

You must do your research on your products. Like I said, the bare minimum you should be using behind a shower wall is a mold resistant drywall. Then you can go from there. There are roll-on membranes that you can go right on top of the mold resistant drywall. That’s next step up then there is full-on wall boards with membranes already attached to them. And you are just silicone the joints together or put patch flaps over the joints to get ready for your tiling. There are numerous systems. So, do your research find yourself a mold resistant or water proofing system that you are comfortable with and then carry on with your project.

We hope you find this information useful. In case you have any questions or need help with your drywall project, give Expert Drywall USA a call and we will be happy to assist!
