A second and third coat are a must to remove the popcorn texture from the ceiling. If you only do one coat, you can still see the ridged texture from the popcorn. Clean Air Interstate Rule". Epa.gov. Archived from the original on 12 April 2013 . Retrieved 20 April 2013.

Drywall screws should be between 30 and 40 cm apart. This distance allows for maximum support with minimal visual distractions from the screws. In the US, the distance is 12 to 16 inches. What is the difference between 14 and 38 inch drywall? Hoisting and attaching panels overhead can be hard work. At the very least, you'll need a helper or rent a drywall lifter tool. As an example, let us assume an area of 1,000 square feet for drywall installation. How many panels needed depends upon their size. In the USA, there are panels available in the following sizes: Environment (wet areas such as bathrooms will need to be drywalled with a specially treated panel to avoid damp and mould issues later on). To hide the fasteners, position them close to openings around windows and doors so the trim will cover them.Mineral Commodity Summaries, January 2006" (PDF).

The combination of the paperboard layers with gypsum sandwiched in between allows for a solid wall panel that is strong, light, and does not burn when exposed to naked flames.

The first step is to work out the square foot area of the sheet you want to figure out the weight of, with a 4-foot by 8-foot sheet having an area of 32 square feet, for example (calculated by multiplying the two dimensions together).

But first, you will need to develop a decent understanding of how drywall works, and what installation processes are considered best. While the process itself is not terribly complicated, there will be some basic construction techniques involved that require preparation. Before you can start the drywall installation process, you will need to obtain several different tools to help you along the way. Plaster, on the other hand, is a particularly hard-drying material made from lime, water, gypsum, and sand. It hardens upon drying and is one of the oldest known building materials in history. It is also significantly more expensive and labor-intensive than drywall. Is it better to repair or replace drywall?

Next, you’ll need to know the weight per square foot, which looking at a 1/2″ standard drywall sheet for this example, is 2.4 lbs/ft ² as per the reference table above. If you have a sloped ceiling which you want to drywall, use a ladder to access measuring the ceiling dimensions. Take the time to mark fastening guidelines every 40 cm or 12 inches from the end of your sheet with your drywall square. When getting your drywall panels cut to size, shorten them by 1 cm for easier fitting. Selecting and Buying Drywall The introduction in March 2005 of the Clean Air Interstate Rule by the United States Environmental Protection Agency requires fossil-fuel power plants to "cut sulfur dioxide emissions by 73%" by 2018. [32] The Clean Air Interstate Rule also requested that the power plants install new scrubbers (industrial pollution control devices) to remove sulfur dioxide present in the output waste gas. Scrubbers use the technique of flue-gas desulfurization (FGD), which produces synthetic gypsum as a usable by-product. In response to the new supply of this raw material, the gypsum board market was predicted to shift significantly. However, issues such as mercury release during calcining need to be resolved. [33] Types available in Canada and the United States [ edit ]The different panel sizes have their own advantages and disadvantages. For instance, you can accomplish projects faster using bigger boards as they cover more footage in your wall. But they’re harder to work with because of their size, weight, and low maneuverability. After the sheets are secured to the wall studs or ceiling joists, the installer conceals the seams between drywall sheets with joint tape or fiber mesh. Layers of joint compound, sometimes called mud, are typically spread with a drywall trowel/knife. This compound is also applied to any screw holes or defects. The compound is allowed to air dry and then typically sanded smooth before painting. Alternatively, for a better finish, the entire wall may be given a skim coat, a thin layer (about 1mm or 1⁄ 32in) of finishing compound, to minimize the visual differences between the paper and mudded areas after painting. The plaster is mixed with fiber (typically paper and/or glass fiber), plasticizer, foaming agent, finely ground gypsum crystal as an accelerator, EDTA, starch or other chelate as a retarder, and various additives that may increase mildew and fire resistance, lower water absorption ( wax emulsion or silanes), reduce creep (tartaric or boric acid). [9] The board is then formed by sandwiching a core of the wet mixture between two sheets of heavy paper or fiberglass mats. When the core sets, it is dried in a large drying chamber, and the sandwich becomes rigid and strong enough for use as a building material. Be warned though, that mixing in wrong proportions can decrease the effectiveness of the mud. If you prefer not to vacuum after drywall installation, then purchasing the low-dust variety of drywall mud is the perfect choice for you. The following few points will take you through every step of the way, and help make sure you come out the other side with a successful and satisfactory new wall. Let's go! Measure the Wall

Plasterboard is commonly made with one of three edge treatments: tapered edge, where the long edges of the board are tapered with a wide bevel at the front to allow jointing materials to be finished flush with the main board face; plain edge, used where the whole surface will receive a thin coating (skim coat) of finishing plaster; and beveled on all four sides, used in products specialized for roofing. Major UK manufacturers do not offer four-sided chamfered drywall for general use. Non-standard features of a room such as arches and curves can cause your costs to increase by as much as double. Ceiling depends on you if you want to drywall your ceiling. If you want drywall installed on your ceilings too, measure the dimensions.If you opt for a more expensive version of the tape, you can buy the fiberglass type. This costs more but is easier to apply as it’s self-adhesive and it’s more durable too. Using the drywall estimator or calculator to determine how many drywall panels you need is very easy. But before you can perform any calculations, you must take the following measurements first: For the Drywall Calculator, input the values of the Room Length, Room Width, and Room Height then choose the units of measurement from the drop-down menu. Calculate the length and width of the room with a measuring tape. These dimensions should be approximately the same as the ceiling dimensions. You can solve for the ceiling’s square footage using these dimensions too.
