Do You Need a Moisture Barrier When Building a Shower Enclosure?

by:Xavier      2020-03-29
Whenever the steam generated by the warm shower hits the cold air elsewhere in the bathroom, condensation occurs.When you condense behind the shower, it causes mold, mildew, Bolt expansion on the wall, and other problems.Moisture and condensation are two of the biggest problems when building a new shower.Prevent these problems by installing some type of moisture or steam barrier each time you shower.No matter how dense you think your shower is, water in the form of water vapor can still enter.Seams in the acrylic shower or broken grouting joints in the tile shower or some missing caulking are all needed to get moisture into the back of the shower.The moisture barrier prevents water or steam from spreading further and has the potential to rot the studs, drywalls or green plates mounted behind the housing.They need to be under your shower pan and behind the shower wall.The moisture barrier can be made of polyethylene or a film directly rolled on the dry wall.No matter what they are made of, without them, your shower will be hurt by moisture.The tile needs a certain amount of support, which can also resist moisture and expansion.To do this, use the cement back plate behind each new tile housing.However, set a 6-before you install the back panel-Mm polyethylene sheet on the nail.Nail the sheets to the nail at the top of the shower, let them hang on the top of the tile tray, and then screw the back plate onto the nail above.If your tile shower is compromised, the back panel will not expand or disintegrate once the water is condensed when it hits polyethylene.The moisture-proof barrier also protects your studs from expansion and warping.The acrylic surround has a waterproof surface and a lightweight structure that can be installed on top of an existing drywall or green board.However, if there is moisture around it will quickly rot dry walls or green plates behind it.Even if you open the wall before reinstalling the drywall and hang the polyethylene film behind the drywall, moisture can penetrate the drywall and condense on the film behind the drywall, which will cause it to rot from the back.Prevent this by hanging the film on the top of the drywall and placing the surround on it.If the moisture penetrates around, it stops on the film and does not damage.When a builder uses a cement back plate in a new building, when you use a waterproof film before installing the tiles, you can remodel the shower in the existing bathroom without replacing the drywall.The waterproof film is like a heavy-Duty paint but dry to a soft, waterproof surface.They protect the drywall from moisture and make it impossible for the drywall to penetrate, so the moisture does not pass through the studs.A film like this also helps to support the drywall so that it can support the weight of the tile on the shower wall.
