i am putting tile on my tub surround walls, and will be using cement board! the sheet rock that is on there is not leveled,is there a trick to make the cement board leveled and plum when i apply it??? please help
Use a level and if the wall isn't plumb you'll have to cut long tapered shims to correct it, nailed on the studs underneath of the cement board.
sheetrock section of your local home depot, butt-strips. Use a level and determine what studs need to be firred out to make things plumb. Make sure to put level horizontally, vertically, and diagonally, so you can get a good view of exactly what the studs are doing. They may be bowed in places and plumb in others. staple or nail the strips in place and re-check with level till it all looks good. Nail up your wonderboard with galvanized roofing nails. if you have any other questions, don't hesitate to ask. Good luck!
