Moisture-Resistant Backer Board: Use a cement board or a moisture-resistant drywall (often referred to as green board) as a substrate. Cement board is preferred because it's more water-resistant and helps prevent mold growth.
You should waterproof all the shower walls before tiling. A tile backer or cement board is typically not waterproof, albeit many are water-resistant. The most effective and reliable solution is a separate waterproofing membrane on primed shower walls before tiling.
Cement backer board, such as HardieBacker and Durock, is a popular choice due to their exceptional durability and resistance to moisture. It's made from a cement and fiber mixture, making it perfect for wet areas like showers.
If you want to create a wet room with wall panels, be sure to tank the bathroom and then add waterproof sheeting underneath the panels.
If you have a shower tray then it is not necessary to tanlk the walls. If the shower floor is being tiiled then yes, it is essential to tank the floor and at least 1metre up the walls. tanking kits are available from tile suppliers such as topps tiles or look for a supplier on the net. hope this helps.
The short answer to the question is, “It's not recommended.” However, this answer only really only suffices if you're converting a room that was never a bathroom into a wet space. Drywall on its own is not suitable for use in bathrooms because it is prone to absorbing moisture and thus losing structural integrity.
FlexStone can be installed over a variety of backer board substrates, including sheetrock, cement board, or even existing tile.
The industry standard, as well as most local building codes, do not encourage the use of a vapor barrier behind and over the tile substrate.
Finally, to prevent moisture intrusion, caulk the gap between the Shower Bead and the shower/bath unit. For additional protection, you're able to lay a bead of caulk onto the shower/tub flange and embed the support leg of the Shower Bead in it, as shown above.
Backer boards serve as a stable and moisture-resistant surface to support and protect tiles from damage and moisture-related issues. As a result, they are commonly used in wet areas like bathrooms, kitchens, and showers, as well as for exterior applications.
Neglecting to insulate and air seal behind shower walls can cause significant heat loss, which can make showers, tubs, and bathrooms chilly. The insulation behind shower walls should be equivalent to the insulation installed in the rest of the exterior walls.
The insulation behind the tub or shower should be equivalent to the insulation in the rest of the exterior walls and should be covered with an air barrier of cement backer board, rigid foam insulation, or non-paper-faced drywall that is sealed at the edges and seams to provide a continuous air seal.
Groutless Bath Walls and Floors in Quartz
Silestone Quartz material are ideal for all surfaces in your bath, such as walls, floors, shower pan, tub deck, and the vanity tops. Quartz material are durable, and require no maintenance. Silestone is available in vast color and patterns.
Plywood panels are vulnerable to moisture damage if not adequately protected. Avoid installing plywood panels directly in contact with water sources or near open showers without proper waterproofing measures such as manufacturer recommended trims and sealants.
Kerdi over drywall backing
Schluter actually recommends sheetrock as a backing. The thinking is that as long as there's a completely waterproof membrane on the front of the drywall that the sheetrock will never get wet.
Install cement board or an equivalent moisture-resistant backing material on walls behind tub and shower enclosures composed of tile or panel assemblies with caulked joints. Don't use paper-faced backer board, i.e., paper-faced drywall, behind seamed tub and shower enclosures.
Water can creep through the tile joints and cause damage to the walls behind the tiles. This is why it's important to waterproof the background that you're going to be tiling onto.
Cement Board and a Liquid Membrane
No plastic sheeting goes behind the cement board. A liquid waterproofing membrane, such as RedGard or Hydro Ban, is rolled onto the cement board and allowed to cure. Then, tile is installed over the membrane.
Transform your bathroom with FlexStyle, innovative simulated tile panels from FlexStone. FlexStyle shower walls emulate the sophisticated appearance and texture of white tile. These panels come as full shower wall panels and are far easier to clean than traditional grout.
FlexStone panels can be seamlessly attached to sheetrock, cement board, or other surfaces using the provided construction adhesive. Complete the look by finishing the joints with silicone, and revel in your upgraded, low-maintenance, stone-look bathroom.
DO NOT use greenboard in these spaces: Saunas and steam rooms. Shower stalls. Rooms with spas or pools.
Look into cement board if you need waterproof drywall. This type of waterproof drywall is designed for wet areas such as showers and bathtub surrounds. Be cognizant that cement board requires a moisture barrier behind it, which makes the installation process longer than moisture-resistant drywall.
