Drywall or cementboard first?
bricksonsecond

Wondering if the cement board or drywall goes in first?

We completely tore the room apart. Now we have the subfloor in as well as all the electrical and insulation and everything else that needed to be done. We're putting in a tile floor, thus we are using cement board. But not sure if you put in cement board and then the drywall or if you do drywall first and then put in the cement board. Not sure if you can walk all over cement board to put in drywall.
Thinking drywall first, but can't find what I need with a google search.

You got me confused. Are you doing walls or floors?

If it's all torn out, do the subfloor first then the walls. That will give the floor a little better support and keep the sheetrock above possible water problems.

Putting the cement board on the floor before drywall on the walls is a little easier. The cement board should be able to withstand traffic; if it breaks from walking on it, then it's not supported well and your tiles would crack. Better to find that out before putting the tiles in.

If you tile the walls, the cement board is attached directly to the wall studs. Do not overlay cement board with drywall; do not overlay drywall with cement board. Tiles attach directly to the cement board. Put the tiles on the wall before doing the floor; this will help prevent damage to the floor tiles.

On the wall, install the cement board before the drywall, as the placement of the cement board is determined by where you will be placing the tiles. Then install drywall on the areas of the wall that don't get tile.

Here's a tip: in areas where the whole wall is drywall (from floor to ceiling) and wider than 4 feet, install the drywall horizontally so the seams between the sheets are horizontal rather than vertical. It will make the joint taping easier, because the joints will be at a comfortable working height. (And if your walls are higher than 8 feet, put the top sheet against the ceiling and the bottom sheet against the floor. Then your filler strip will be in the middle where it's easier to tape.)
