Q:Silicon calcium board with gypsum board is the same thing? Silicon calcium board Our property here says they sell us a piece of RMB8 But the gypsum board we can take a 3 yuan at least 3 yuan The board is written behind the three big gypsum board but they are hard to tell us that the gypsum board is silicon calcium board Will these two things really be the same thing?

LZ first clear what is "calcium silicate board" or "silicon calcium board", which is two different things. Calcium silicate board - cement as the main raw material. Silicon calcium board - gypsum as the main raw material. Gypsum board: can be divided into paper gypsum board, decorative gypsum board (that is, silicon calcium board), plant fiber reinforced composite gypsum board and other types. In general, silicon calcium board is a class of gypsum board. The largest gypsum board on the market is the gypsum board, which adds a layer of paper to the surface of the plaster, which reduces the risk of cracking from the plaster itself. The plasterboard has a complete line. Strength is not high. Silicon calcium board is no surface paper, but in the plate inside the glass fiber reinforced materials, all the calcium calcium board is a composite material, and the paper gypsum board is not a composite material. Calcium calcium board than the gypsum board light, and strength High, but the silicon calcium board is not a complete pipeline, the basic or manual operation, which led to the size of the silicon calcium board factory uneven, the product quality gap is huge. Please LZ according to the above to determine whether the calcium calcium board, 8 of the calcium and calcium plate and three of the gypsum board are in the low-end products .8 block calcium calcium board ex-factory price is 3-4 yuan.

Q:Is it better to use a mortar or and adhesive to dot and dab plaster board to walls?David?

If the background you are fixing to is very rough then I would dot and dab with bonding compound. If the background is straight and true then I would use 2 by 1 or 2 by 1.5 battens. Then simply screw the plasterboard to the timber making sure the battens are centered according to the width of the sheet. Normally 1200 is the size of the slab so your battens will be 600 on center vertically with one batten running horizontally on top and one on the bottom that will also give you something to fix the skirting board to. If you decide to dot and dab, fixing skirting boards and corner beads will have to be stuck on by adhesive. Bonding compound can be used for corner beads as long as you sponge off any excess leaving room for the finish skim coat.

Q:Gypsum board ceiling price how much a square meter how much money?

Gypsum board ceiling price is expensive and cheap, mainly depends on the material, wages, craft and other factors, the ceiling is divided into the following four parts. 1 with more thick gypsum board, in general, 9mm with 12mm two, the lowest price is 18,37 each, the brand, then about each of your 5-10 yuan 2 What kind of material used as keel, in general, wood and light steel two, the lowest price is, anti-corrosion wood side 25 bundle of four (400 * 25 * 25), light steel 8 dollars a main keel 30mm width. An average of 10 dollars per square meter of wood, light steel 12 dollars. 3 accessories, steam nails nails, dry hanging nails, white latex, etc., more than 100 square meters, less than 2 yuan per square meter. 4 wages, the gap is relatively large, in general, an area of more than 100 square meters, flat top 40, modeling roof (with light pool or convex shape) 60 square meters, if it is a large city may be higher. In summary, the gypsum board ceiling (single, no curve shape) cost is generally between 75-180 dollars, if the workers quote the profits on the float is about 30%. Can help to!

Q:how can i remove ceramic tiles from plasterboard walls?

Use a chisel to remove the first tile starting at the top and working down. Once you have the first tile removed you need a flat wide blade - I usually use a strong Putty knife. You will find this time consuming but the only way to do it. Once the tiles are removed you will find you will cut into the plaster board a little. Try not to cut into it too much. Get some Cornice Cement and where the wall is rough go over it with the cornice cement. Dont mix a lot of the cornice cement at any one time as it goes off (hardens) quickly. They use cornice cement over gyprock to fix any imperfections or in the corners over the plaster tape. It is easy to use and easy to sand if you need to but is dusty when sanded. Hope this helps

Q:how do you hold insulated plasterboard on the ceiling while you drill it?

you have about 3 choices..... rent a stand you put the bord on it then hand crank it to the cieling......or get some 1 to help you....or make a tool its just a couple of 2x4's nailed together to form a T make the long part of the T a little bit longer and just kick it in on a slight angle

Q:maximum temperature generated by wood and plasterboard house fire?

a lot depends on airflow, but 2000 degrees F is not out of the question.

Q:I live in a cheap house that has horizontal joists holding up a plasterboard hollow wall - hope this makes sense. Looks like someone opened the door too hard one day and halfway across the wall is a vertical crack. I have used wood glue, polyfilla and dulux flexible paint, but its still a nasty piece of work. i can't sand over the glue now!PS I live in the UK, so don't refer me to Walmart or use brand names as I can't just nip over there!

Hello UK. Well it sounds like you have a mess. What I would do is cut out the damaged areas between each stud making sure that you take out the plasterboard half way into the stud. Then replace the area with Sheetrock or plasterboard. The board should be cut to fit the hole and you should be able to screw to the existing studs. If you dont have enough board to screw to, then build a new box made of 2x4s and then put up your new board. Then its just tape and mud to finish.

Q:Three building materials, plasterboard, brick, and wood, all the same thickness and area, are sandwiched to form a wall. Temperatures are 27 degrees Celsius at the inside plasterboard surface and 0 degrees celsius at the outside wood surface. Find the temperature where the plasterboard meets the brick and where the brick meets the wood.k for plasterboard = .40k for brick = .70k for wood = .2

1/0.4+1/0.7+1/.2 = 7.5+1/.7 or about 8.93 the plasterboard drops 27*2.5/8.93 C : about 7.7C so temperature at plasterboard/brick is around 19.3 C the wood drops twice as much about 15.2C so brick-wood interface is around 15.2C. Appropriate numerical precision when the conductivities are given to 2 significant figures means your answers should be about 19C and 15C. The brick is awful! Have a look at the link below; even thermal grease isn't much worse than this brick but the values do seem to be pretty typical.

Q:There's a substantial dent (bordering on being a deep crack/hole) in the middle of a 3 square meter piece of painted plasterboard. I need to repair it with something durable as it's in a prominent place and thus am not sure plaster will suffice. On-top of that it will need to be painted. What should I use?

I would paint it with a flat latex paint. That will help hide some of your mistakes. Good luck!
