Drywall should not sit directly on the tub as it can “wick” moisture and will eventually fall apart (even green board) if the tub is not kept caulked properly. There is no need for drywall behind the cement board and I have never heard of it being done that way.
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.
Similarly, do you need sheetrock behind backer board? Because cement board can be used either for floors or walls, the surface below the cement board will vary: In such wet areas, never install cement board directly over drywall or green board. Instead, first, remove the existing surface material, then install the cement board over the studs and membrane, as applicable.
Similarly one may ask, does sheetrock go behind shower pan?
Drywalling a Shower Pan Because the shower pan is screwed to the framing, there is no wall behind or below the base. Therefore, the drywall has to go in after the shower pan.
Do you drywall over the tub flange?
You can bring sheetrock right down to the flange just like in the picture as long as you aren’t going to tile over it. I would suggest using sheetrock over backer board on surfaces which you intend to paint.
Should I insulate behind tub surround?
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.
What is waterproof drywall called?
Drywall can be primed and painted to be waterproof. Although water resistant drywall — commonly referred to as greenboard or blueboard because of its color — is available at most home improvement stores, you may find yourself needing to waterproof your current drywall.
Can you put tile on purple drywall?
Besides its mold and mildew resistant properties, purple drywall is also fire-resistant. Ideal applications for purple drywall are around toilets, sinks, vanities and as a tile backer board for shower ceilings or kitchen/bathroom backsplashes.
Does sheetrock go all the way to the floor?
If you’ve already installed drywall while letting it rest on the floor, all is not lost, but you have your work cut out for you. Use a drywall knife to fill the large gaps with ready-mixed joint compound.
What is Blueboard?
Blue board drywall is also known as plaster baseboard. Blue board is used for veneer plastering, and the surface paper has special absorption qualities. Blue board drywall is not made for mud, tape, or paint. It works extremely well in bathrooms or places with a lot of moisture and helps reduce noise.
Can I use regular sheetrock in a bathroom?
You can hang drywall in the bathroom but not the same type that you hang in the rest of the house. Bathroom drywall must be moisture-resistant, and it’s colored green to distinguish it from the regular variety. It isn’t appropriate for areas that actually get wet, however, such as shower and tub surrounds.
What kind of drywall do you use for a bathroom ceiling?
Conventional drywall is commonly used for ceilings in non-shower/tub areas of bathrooms, although some builders prefer to use moisture-resistant drywall — a.k.a. greenboard — instead. Moisture-resistant drywall is similar to standard drywall but has face paper that’s treated for extra resistance to mold and moisture.
Can you waterproof drywall?
Yes, you can make drywall pretty much waterproof if you coat it on all sides and edges with water-based urethane before you install it. The secret tip to making the drywall waterproof is to coat the paper surfaces of the drywall, including the edges, with clear water-based urethane BEFORE you finish the drywall.
How do you trim around a bathtub?
Baseboard Measure the length of the base of the tub. Clean the area around the base of the tub with soap-scum remover and water. Cut the tip off a tube of plastic trim adhesive at a 45-degree angle with a utility knife. Press the baseboard into place along the bottom edge of the bathtub.
Should cement board overlap the tub?
ANSWER. ANSWER – No there should not be a gap between the top of the bathtub flange and the backer board on the wall. The backer board should overlap the tub flange so the tile has a stable backing to attach to. This requires shimming the backer board out from the studs so the wall is plumb.
