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.

Yes it is.

Wipe it off with a rag dipped in warm water.

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.

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

You can install tile glue right onto drywall. However if you are doing this in a bathroom, first consider all the advantages of using concrete/ fibre boards around the tub and shower. They are far more water resistant, made for tiling, easy to work with and come in handy sizes 30x60 and 36x60. - I have used this in preference to drywall for over 10 years and never had an unhappy client.

It's just a little less than one standard sheet of board. If you take it as going upto the ceiling in a regular 8 ft.high room, then it's a section just under 4 ft. wide and ceiling height.

There are a number of factors to consider. -Is this a finished room, if not who is going to remove all the furniture and cover the flooring. Are you going to re-paint the walls after the job ( they will almost certainly need it) . Actuelly remiving the drywall is a fairly simple job, but all the other things including disposing of it make giving a figure very complicated.

There are no metals in drywall or plaster.

The standard wallboard and fire resistant wallboard in a large variety of sizes were well established in the 1960's. Other types like moisture resistant and acoustic boards were coming into use .
