Drywall

If you have wood studs I know of no code restrictions. I think sheet rock screws make good wood screws for many different applications.

If you have metal studs, the screws won't hold the box solidly to the stud. This may be a violation; I didn't look it up; but many things are done in a pinch. If this is your situation, connect the box to the stud as best you can. Then, once sheet rock is added and your device and faceplate, there won't be a problem because it all goes together to make an adequate installation.

I am NOT saying the box can be free-floating. It should be held more or less in place with the screws. If it is free-floating then you are depending on the faceplate to hold the box and device in place. This is a violation of code.

There is paper tape and fibre mesh tape.

Drywall as we know it has been around since about 1890.

Preferably you cut and fit a patch of drywall. I always do that for holes and gaps over 1/2 inch.

The weight of one sheet of drywall 12'x2'x1" (feet) would typically be around 53-57 pounds, depending on the specific type and thickness of the drywall.

Some of the water-resistant versions are green on one side.

No. The art will fall and leave a hole in the wall.

Yes. Use metal screw in wall anchors. They are good for up to 50 lbs.

It is nor harmful, but does dry your skin and may make some body parts itchy.

Considering only safety, there is not much hazard. There may be electrical wires inside the wall, so keep that in mind. You would not want to cut into a wire with your nail.

A better question is if it's a good idea, and that depends on what you are trying to do. If you want to put in a very small nail to hang something lightweight, like a small picture, you can do that. Drywall is not very strong, but it can carry a little weight. If you want to hold something heavier, you will need to find a stud (the vertical wooden boards that form the structure of the house). A nail put through the drywall into the stud will be able to carry considerable weight. Since you may someday wish to remove this nail, I would suggest you use an appropriate screw instead.

Keep the nail or fastener to a reasonable length (appx. 1" more than the drywall thickness )and you should be OK. You could also get an inexpensive electronic stud finder with electrical wiring sensor if so inclined.

That appears to vary widely across north America. In my area,western Canada, it is about 45 cents board foot for regular sheet.

You can both estimate the total square feet of drywall, also known as gypsum board, you'll need and the number of sheets. ... Drywall needed = total area/sheet size.

1. Multiply the length and height of one wall. ...
2. Record the area.
3. Repeat this process for all walls.

No, you plaster or mud it first.

250 sq. ft would take me about a couple hours without stilts.

is it walls only--- is it cielings only-----or both?

I say a drywaller.

No, it is better caulked with a water resistant caulk. ( Also it should be at least water resistant drywall or concrete/fibre board.)

You will get a better result using drywall mesh cloth, 2 grades about 120 and 180.

This boardis similar in composition to Type X drywall,

except that it has more glass fibers,

and, it has another ingredient in the

gypsum core. This ingredient is a

shrinkage-compensating additive, a

form of vermiculite. When exposed to

high heat, the gypsum core shrinks

but the shrinkage-compensating element

expands at about the same rate

as shrinkage occurs in the waterdepleted

gypsum.

The gypsum core then is more

stable in a fire and remains in place

even after the combined water in the

gypsum has been driven off.

No, it doesn't.

Regular drywall primer.

Only if you put on a good primer first.

There's nothing like a simple concise sentence - LOL -

If you have a drain in the room, power wash it, - if you don't it's going to mean a lot of scraping with metal spatulas and brushing with wire brushes to get it clean.

Good luck with it ..

It's no different on drywall than it is on any other surface. You spread the cement the same way, you apply the tile the same way.

Yes it is.

Wipe it off with a rag dipped in warm water.

Drywall mud is the thick, goopy white stuff you use to fill the seams between boards.
