You must translate this is Finnish langvitsh:
Levyt valmistetaan joko luonnonkipsistä tai voimalaitoskaasujen puhdistuksessa syntyvästä kemiallisesti puhtaasta sivuainekipsistä. Pieneltä osin käytetään myös kierrätettyä kipsiä, lähinnä valmistusprosessin hukkaa.
Valmistus aloitetaan jauhamalla raaka-aine tasalaatuiseksi ja kuivaamalla se. Seuraavaksi kipsi kalsinoidaan, jolloin suurin osa kidevedestä poistuu, ja tulokseksi saadaan stukkokipsiä. Stukkokipsijauhe puhdistetaan sähköisesti ja siihen lisätään lisäaineita ja vettä. Aikaan saatu massa pursotetaan kahden kartonkipaperin väliin ja puristetaan määräpaksuuteen. Kovettumisen jälkeen levyt katkotaan ja kuivataan. Lopuksi kuivatut levyt katkaistaan määrämittaisiksi
The translation is :-
The panels (drywall panels) are made either of natural gypsum or chemically pure gypsum, a sideproduct of (the) refining of powerplant gasses. A small amount of recycled gypsum is used, mostly excess (leftovers) from the manufacturing process.
Production is started by grinding the raw material till it's homogenous and then drying it. Next the gypsum is calcined, at which point most of the chrystallization water is removed. The result is stucco gypsum. Stucco gypsum powder is refined (cleaned?) electrically and additives and water are added. The resulting mass is extruded between two cardboard papers and pressed into intended thickness. After hardening the panels are cut up and dried. Lastly the dried panels are cut to final/intended size. (fixit895)
Can you repair plaster with drywall joint compound?
yes you can roll on joint compound but that is usually done when you want a textured wall or cieling and does require a great deal of compound to use-- it is also a slow tedious process since the compound is thick and not so easily movable. If you are looking for a textured wall or cieling my advice is to first trowel the compound using a 1/4 inch toothed trowel and then roll it out with the texture roller. you cannot use a paint roller to roll out joint compound. There is a special textured vinyl roller for this purpose it looks like a roller created from a spool of wire.

How many dry wall screws per 4x12 sheet?
If you drywall on 16" on-centre studs, with sheet length perpendicular to the studs, and screw the two outside length edges at 6" spacing (as it should be) and the two interior studs at 12" spacing, the answer is 48 drywall screws per 4'x8' sheet.
How do you mud drywall joints?
apply the mud with a drywall trowel into the joints (you can get premixed mud) and press the tape into the mud. cover the tape with another layer of mud. let dry and sand it smooth. it may require more than one layer of mudding and sanding.
For inside corners use the same method, but fold the tape 90 degrees into the corner.
For outside corners nail up prefab metal or plastic corners and cover with mud, then sand.
hope this helps!

The best way to dry wood for carving, is to do it slowly, unless you have a drying kiln. Most wood for carving walking sticks has a general rule that it needs to be dried for at least a year for every 1" diameter of the walking stick.
What is the weight of a sheet of 4'x8'x58 drywall?
Standard drywall weighs about 3.4 lbs per sq ft per inch thickness. Water resistant drywall (greenboard) weighs about 3.9 lbs. per sq. ft. per inch thickness. Firecode C drywall weighs about 4.2 lbs. per sq. ft. per inch thickness. These are approximations, as the ratio of core vs. covering varies for different thicknesses, thereby varying the exact weights. So, 1/2" thick standard drywall weighs 3.4 x 0.5, or 1.7 lbs per sq. ft. 4' x 8' x 1/2" thick sheet weighs 1.7 x 32 s.f. = 54 lbs. 4' x 10' x 1/2" thick sheet weighs 1.7 x 40 s.f. = 68 lbs. 4' x 12' x 1/2" thick sheet weighs 1.7 x 48 s.f. = 82 lbs. 5/8" thick standard drywall weighs 3.4 x 0.625 = 2.2 lbs per sq. ft. 4' x 8' x 5/8" thick sheet weighs about 70 lbs. 4' x 10' x 5/8" thick sheet weighs about 88 lbs. 4' x 12' x 5/8" thick sheet weighs about 105 lbs.
Depends on the wall sizes of each job. I always found it faster working with 4x8 sheets personally.

What ever you decide to choose to charge for the hanging you normally match that price for the taping, and about 600+ for the spray and texture.... Even more if they want the wall PCV'd

Is there a certain type of drywall tape to use in a shower?
Drywall use should be avoided in the shower area if possible. Any are receiving a daily dose of constant wetting will be prone to moisture infiltration and deterioration. On ceilings that might only receive a smattering of water, any tape should be o.k., as long as the drywall is finished, primed and painted.
How much drywall do you need for a room that's 1000 sq ft?
You will need three more bits of information.
1. How high are the walls.
2. What is the length of the room.
3. What is the width of the room.
Let me give you an example.
Height of walls = 8 ft.
Length = 50 ft.
Width = 20 ft.
Each piece of drywall is 8' X 4'.
In this case, the height of the walls exactly matches the height of the drywall; so you won't have to make any cuts in that dimension.
Figure out how many sheets you will need for the 50' walls.
50' / 4' = 12 1/2 pieces of drywall.
There are two of those 50' walls; so multiply by 2.
12 1/2 X 2 = 25 pieces.
Now for the short walls.
20' / 4' = 5 pieces of drywall.
Again, there are 2 short walls, so multiply by 2.
5 X 2 = 10 pieces of dry wall.
Add what you need for the long walls and short walls.
25 + 10 = 35 drywall sheets.
Answer: 35 drywall sheets.

How do you fix a hole in drywall in the ceiling?
Depends on how large. up to 6 inches square cut a piece of sheetrock the right thickness 8 inches square. on the back side, cut thru the paper 1 inch in all the way around. break the sheetrock and peel the 4 1 inch pieces off the front paper. This will leave you with a 6 inch square piece with a 1 inch border of paper Mud the 1 inch strip and apply to the hole. Smooth the strip and mud, Top coat the patch and sand. For larger holes, strips of wood, plywood prefered, 2 inches wide and as long as the sides of the hole can be placed behind the sheetrock and screwed in place. The piece of sheetrock filling the hole is then screwed in also, tape, mud and sand. For very large holes, you need to cut the hole back to the studs. Split down the middle of the stud and replace as much as needed in height. A plywood backer can be used here also at the top and bottom of the patch

Gemini coatings in El Reno Oklahoma has a laminate patch system. If you call them or email them, they can refer you to a local repair guy that has their system. You would be surprised what can be fixed. However, the cost can surpass the cost of a new top even if the backsplash can be saved. There are many epoxy base products on the market that can be colored and used as a filler. Edge damage demands creative repair.Surface damage can be fixed by insertion of same product or with tiles. mr odd job
