I have come across many people that believe they can put drywall up for their shower walls. This is a common misconception. Other companies advertise that it is safe for drywall to be put up with their systems. Here is a photo of what can happen when using drywall in a shower: The first photo shows your horror show of what can happen underneath your floor of where your shower is, the second photo shows this drywall that has molded due to water damages. These damages are very unfortunate but they are preventable, if you take the right steps.
Rarely do I come across any drywall that isn’t damaged in some way, when faced with shower repairs or remodeling someone’s shower.It’s a product that absorbs water easily and gives mold and fungus an excellent spot to live, while it’s destroying your home.
This is truly a home repair nightmare.
There wasn’t any type of vapor barrier behind the tiling and the drywall. We recommend to attach the CertainTeed Vapor Barrier, once this is attached put up a cement board on top. If you only use drywall. once the drywall is wet, it’s not long before mold, mildew and fungus starts the destructive process of destroying the drywall, and wood framing.
A cement board will give you the greatest resistance to moisture and mold so your floors / walls are protected. Look for a cement board that has the following features:
- Moldblock Technology: This enables you to achieve perfect score on industry mold tests.
- Make sure it contains no paper facing, which serves as a food source for mold, or gypsum, which can disintegrate with continuous moisture exposure
Home Repair Tip: This one isn’t going to be easy. I would remove the entire shower and the rest of the damaged building materials, and rebuild it correctly.
