How do I get my ceiling level?
I'm getting ready to hang drywall on the ceiling of my gutted sunporch. I pulled a level line from a beam that divides the room to the end @ 18 feet and the joists are not any where near level (deflection of b/w 1/2 and 3 1/4 inches).
I'm a carpentry novice.
1. Do I need to level it? I didn't notice it before demo. It won't be an expanse of drywall either (do you even call it drywall when it's on the ceiling?) - every four feet there were decorative battens with chamfered edges. They hid the seams of the fiberboard.
2. If I should level it, HOW? Let's hear those carpenter tricks of the trade.
3. The room is partitioned by a large exposed beam and the level of the ceiling on one side of the beam is 3/8 of an inch different than the other side. Do they need to match, and if so HOW? http://www.diychatroom.com/picture.p...pictureid=1408
I want to know what (and how) you would deal with this if: it was your house.
Is this sunporch heated? I'd only put sheetrock up if this was an interior type space.
This is living space - heated and A/C. It is an old souther sleeping porch that is entirely closed in.
if it doesn't matter to you if it is level, it doesn;t matter BUT a quality job would mean the ceiling gets leveled.
as to the 3/8" difference; if there is a beam seperating those 2 halves, it will most likely not even be noticable.
as to how to make the ceiling level;
there are several ways;
shiming the rafters
sistering boards onto the rafters
and the way I just recently learned of; suspended
the last one is made by using a product that looks similar to a typical suspended ceiling with lay-in panels but is designed to have the sheetrock screwed to the grid. For the life of me, I can't find it online. If you are interested, I will have to ask the carpenters at work tomorrow for the manufacturer of the product.
I'm sure there are other means. Maybe the others will have some ideas.
You can find the drywall "grid" systems at the United States Gypsum web site (USG.com) but hardly practical in this case. Pull a string across the room in several places to determine your low spots. You can add a 2"x4" to the side of the high/low joist with 3" nails or screws to flatten things out. Actually, these days 1/2" isn't that bad and probably won't be noticeable (especially if you're going to have a texture). 3/4" it's hard to get the rock to pull tight. If it were mine I'd want it within 1/4". I recommend using adhesive also which helps "bridge" small gaps and reduce the number of fasteners necessary.
