the green board is usually only used around the tub or in the shower area or where you have direct water contact to a wall. it's not necessary to put green board anywhere else in the bathroom.
not the same as greenboard. greenboard is often used for high-moisture areas such as showers, in which the greenboard is heavily coated with bathroom-quality paint or with cement board on top. greenboard is less effective at inhibiting mold than is mold resistant drywall. however, greenboard is less expensive than mold resistant drywall.
do we use the greenboard in the shower area or do we use the heavier cement board even though it's typically only for tile , wouldn't this be a better board to use for longivety of water proofing
after much research, i have a lot of conflicting advise about the need to add a vapor barrier before installing the backer hardy / cement board for my bathroom shower. the 'expert' at seven trust, and another guy on youtube seem to think this is a very good idea, and even suggest sealing it with roofing tape.
as far as moisture control. a good bathroom paint and exhaust fan should control it. i have never tiled an entire bathroom ceiling. when tiling a shower ceiling i have used cement board, but i am planning on trying gp tilebacker next. gp makes some other moisture resistant greenboard alternatives you may want to check out.
yes, you need to use a vapor barrier with green board. in bathrooms or other wet locations, water vapor will try to penetrate into wall cavities. this will cause wood rot in cold climates.
hoping someone can help clear up disagreement between husband and contractor. we are having blue board with plaster veneer for renovation instead of drywall. for the bathroom, my husband thinks we need green board with something over that then plaster veneer over that. contractor says blue board with plaster veneer is fine.

install green-board drywall in areas subject to moisture, like kitchens and bathrooms, but with hot-dipped galvanized drywall screws and a screw gun rather than standard drywall screws.
its good for the rest of the bathroom. greenboard has a waxy surface that makes it difficult to get tiles to adhere to it. one solution is to coat it first in a layer of kilz or other flat sealing primer, which will stick to the board while providing a suitable surface to hold the tile.

the exterior paper has a green tint to it helping to separate it from standard gypsum board, and leading to the product being known by most people as greenboard. its thicker. while standard drywall comes in ¼ and ½ thicknesses, greenboard is sold in ½ and 5/8 thicknesses.
first, do not put backer over greenboard. there needs to be a vapor barrier behind the backer, heavy mil plastic or 15 lb felt. 1/2' cement board is the better material. but in any event, the backer does need to overlap the tub flange. you need to fur out the studs with lath spacers so the the backer board sheets hang plumb.
if it is to be covered with texture, primer and paint, you need a higher level of finish which means one coat of mud over the joints to adhere the tape followed by two more coats of mud. use all purpose drywall mud. if tile or a surround will cover the greenboard, you only need a level 1 or 2 finish.
green board is water resistant it is not water-proof. green board is highly efficient in bathrooms and kitchens where moisture is frequently in the air, but it is not the drywall that should be set behind tile in your shower or any other areas where it can come in direct contact with water.
originally, greenboard was used as a direct backer board for ceramic tile in highly wet areas such as showers or bathtubs but this usage began to be phased out in the 1990s. cement backer board such as durock is best used for tile in highly wet applications such as shower stalls , with greenboard and other water-resistant drywall panels kept only to high-humidity areas.
green board is basically sheetrock with a waxy paper face. it's not as stiff as cement board, nor as waterproof, both of which are nice to have when applying tile. can you use it? sure. it's been done before. is it to code? not sure. you'd have to check with your local authorities. if you decide to use it, see if you can find a product called 'redgard'.
replies. greenboard mr drywall in bathrooms requires 16' oc ceiling framing and backer board on tiled surfaces. in areas with uncontrolled moisture or wicking moisture such as sub-grade concrete walls , non-paper faced drywall is wise. there's already too much cement in a typical home and no need to use it for wall board as well.
