I have hanged the drywalls on both the ceiling and walls. My questions is how should I tape the joints between the ceiling and walls? Should I use a regular paper tape, a fiberglass mesh or a paper corner bead (inside corner)?

Indoor ground artificial marble paving after the bow is the reason

I was replacing a bathroom fan and the new bathroom fan is bigger than the old one. I took out the old one. Then I used a pencil and traced around the new fan. Then I used a reciprocating saw for the first time and got a little crazy with it. Now the hole is slightly too big and when I put the grill cover on the fan, I can see the hole. I'm not sure what to do now. I still got old pieces of the ceiling. Maybe I can do something with it?

It sounds like when you put the fan in you can see holes around it. If that is correct then get some cardboard and wrap around the fan two or three times around the fan where it fits through the hole. So later when it is removed it give the correct gap around the fan fit to the hole.Now you should be able to secure the fan in place but not up tight to the roof, so you can still get plaster into the gap. Then get some plaster filler. you can get it from hardware store. And with a scraper that is used for plaster fill the gap. Let it dry. You then take the fan out and then remove the cardboard and discard. With the cardboard out their should be just the right amount of gap for the fan to fit back in snuggle and perfect. Use just enough cardboard as you think will do the job. The plaster also sticks to the card board and not the fan housing. You can also rap some Glad Wrap around the cardboard on the out side and it will pull away from the plaster easier when it is dry.Then sand, then you may need that repair with the fiber netting that sticks to it, to strengthen the around the hole. ( buy from hardware. just ask them and they will know. ) stick some of that on to strengthen it and put more plaster on. Let dry, sand and paint. If you google wall plastering repairs you should be able to get some demonstration on how to repair walls with holes so it will show you how to use the mesh to repair. It is not really very difficult. Good luck.

hey. i am moving my room into another room in my house. The only problem with this room is that the ceiling is quite old and one part of it fell off. I need to fix this part that fell off. I think the whole ceiling is plaster i guess but underneath the plaster are these really skinny wood boards with something that looks like cement between them. Can i just do the standard drywall fix with a new drywall piece and some mesh and can i nail the drywall into these boards? I also need to peel ugly wallpaper off too to paint it. If i could just fix this part of the ceiling, things would be great. Oh, the whole is like 3 feet by 2 ft so how much would the drywall be to fix it. i cant get it done by a proffessional because i have no money and my mom will by me the drywall. A lot of help appreciated. thanks.

The thin boards will probably break if nailed into, try using a nail to find the studs in the ceiling.Then make the hole into a square.Drywall isnt very expensive. It comes in a few different thicknesses though 1/4,1/2, 3/4. Measure the depth from the hole to the ceiling to see what thickness you need. Then you can cut the new drywall and screw or nail to studs. When cutting drywall use a razor on the white side to score the lines needed to cut, then you can break it and cut the paper on other side, real easy. If the hole depth is less than 1/4 then you may be able to use drywall compound to cover the area. Just use a putty knife to spread it on and sand it after it dries to make it smooth.
