Drywall

You should use green rock in wet areas. For backsplashes (kitchen) there are products that are easier to work with, but it will work.

You mean " taping and mudding". They have a way of charging it by the foot, but it always baffles me. A lot depends on the size and shape of the rooms and if there are stairwells and how many. I always get 3 Tapers to look and quote me a price.

About 50% more than the 1/2 inch ,because it's unusual and not in much demand .Generally 18-20 per sheet.

6 dollars per board and you dont supply anything! jobs smaller than 30 boards you need to adjust...i charge 150.00 just for a closet or maybe ceiling patch..always have a min. no matter how small....if u can get 7 or 8 a sheet your golden...i have gone as low as 5 but twas a long time ago!

I spackle holes in the wall with Alexll in a caulk gun. I've been using this for about 4 years and still haven't found anything better, though I try everything new as it comes on the market. Alex is easy to use, dries fast and can be painted. I smooth it after applying, with a small plastic spatula and unless it's a very big hole it almost never shrinks. I also use it to seal the small gap on top after fixing new baseboard to walls. My 'caulk box' in my van always has 3 tubes of Alex in different colours.

Between $0.80 and $1.20 per sqft for materials and labor. Between $0.60 and $0.90 for labor alone. Paint ready. The smaller the job, the higher the price per sqft.

Note that is is per sq ft of wall space, not floor space. So a 10x10 room with 8' ceilings would be 40' of wall x 8' = 320 sq ft.

The side that looks like cardboard paper goes to the studwall.

Drywall hammer, tape measure, drywall rasp, metal cutters (straight cut), pencil (never use a pen), razor knife, pipehole knocker (preferably copper pipe), chalkline, T-square, router (optional), screwgun, drywall horse, kicker bar (for jacking up bottom sheets on the walls), and a good partner than can pull his own weight.

If your local building code requires a fire resistant wall or ceiling, then 5/8" is mandatory. Otherwise you can at present use 1/2" or 3/8". Warning 3/8" seems to be going out of production. You can buy it now, but if you need to replace some of it in a few years it may be difficult to obtain; then you either have a step in the wall or replace the whole lot !

This is a joke right? Answer is - they're cheap!

I took my left over drywall and cut it into 12-15.5 inch sheets and glued it inside the wall (interior walls) between the studs I wanted to be more sound proof. I did it in the bathroom and my bedroom. Obviously you have to do it after one side is done and before you put the final sheets on the other side. You can do it to outside walls but you will limit insulation space and would have to glue it to the plywood or particle board.

The paper on the exterior of drywall made in 1977, or the spackling compounds use to bridge the space between two pieces of drywall, may contain asbestos, or it may not. The only way to know for sure is to have a sample collected by a person who is qualified to do that, and have it analyzed by a lab that is qualified and experienced in asbestos analysis.

You have several choices when repairing a mirror. You can try the Gorilla glue and put it at several places to make it secure. If that does not work you may have to make a new frame to hold it in place.

Anything above mid -fifties will work. Ideal is about 70 deg.

You would not use sandpaper. You would use a screen. The sanding screens usually come in an 80, 120, and 220 grit.

It depends where you buy it and what exact style of sheet. There are at least 12 different sheets in stores like Home Depot, and hundreds in drywall wholesale stores. A basic 4x8 1/2 inch is about $11 in my area.

It depends on how deep the water was. Normal answer is yes or you will have various nasty molds to deal with. Also the drywall will never be as strong.

There are different types of drywall. Green rock for wet areas in bathrooms. Exterior grade 'rock for porch ceilings. 5/8" X is used for garages. There could be endless floorplan variations which will affect how many lineal feet of wall space you have. You could have several different ceiling heights which will affect your material square footage. Your going to have to do the math on this one or take it to a professional.

Yes it is easily damaged in general.

Use a good mastic or adhesive

That depends how it's attached to the cement. eg, Is it on 'furring' or is it nailed directly onto the cement.

3.5 sheets to cover that.

To find a reliable drywall contractor try looking in your area by asking friends or asking people who are involved in the areas around drywall. With lots of asking you will surely be able to find a reliable drywall contractor.

Even if it's a small hole , you are calling out a tradesman to do a job. I have a 2 hour minimum regardless of how small the job is. How else could they account for driving to your house and back to the next job. -However, I will tell you how to do your own repairs. If it is truly small, less than postage stamp size, get a caulk gun, a tube of 'Alex ll' and a small plastic spatula. Caulk the Alex into the hole, then immediately smooth it over with the spatula. Now leave it 24 hours to dry and shrink, then give a second coat. this time be careful to leave no ridges or visible edges. After this dries use a good primer on it. - - If the hole is more than 3-4 inches, don't despair, we just use different stuff. In this case get a kit called 'Fibatape Crackstop' and a small bucket of drywall compound (both from Home Depot ) -The kit has full instructions and I don't need to repeat . This way you have the satisfaction of doing a job yourself AND saving 80-100 dollars.
