What Is Plaster Made Of?

Plaster is one of the most commonly used materials when it comes to building construction. It’s a crucial component that’s incorporated in coating walls, ceilings as well as partitions and it hardens on drying. Plastering is one of the most ancient building materials which has taken over mud to plaster reed or sapling huts so as to serve as a protection against the elements. Here, we’re going to take a look at the multiple compositions of plaster. These components are very important due to the fact that they form a protective coating on whatever they are used on. They work to protect surfaces such as ceiling and underlying walls from scratches or any form of damage.

Plaster comprises a few materials which includes gypsum, lime or cement and all operates in a similar way. Gypsum is made of calcium sulfate dihydrate and it’s the main component of main forms of plaster, sidewalk chalk, blackboard, drywall and more. Meanwhile, lime plaster is made up of sand, water and lime ( mostly non hydraulic hydrated lime). And lastly, cement which is a mix of suitable plaster, portland cement, sand as well as water.

The plaster is usually produced as a dry powder which is mixed thoroughly with water to create a stiff but also a paste that’s workable immediately before it’s applied to the wall or ceiling.

It’s quite easy to confuse a drywall with a plaster but there are some differences. Not only is plaster a much older style of wall construction than dry wall, but it’s also a lot more expensive than installing a drywall. Plaster walls are also able to provide you with a more durable finish when compared to a drywall and it makes for a better quality finish.

Also referred to as drywall, plasterboard is a panel that features an inner layer of gypsum and spread between facer as well as backer paper. It is mostly incorporated in the construction of both interior walls and ceilings. Plasterboard can be made to be humidity resistant, fire resistant as well as noise resistant. Due to these reasons and also the fact that it’s very easy to install and very affordable, plasterboard is a very popular choice when it comes to interior walls and ceilings.

One of the major issues that most homeowners face when fitting plasterboard is the thickness required to make the project a long lasting one. But not to worry, we got you covered! If you’re about to install plasterboard for your ceiling and wondering the thickness that’ll be appropriate, then you’ve come to the right place.

These sizes are designed to provide the much needed support to the standard stud spacing which is 160 cm. Depending on the manufacturer, plasterboard can be in four different widths.

Now talking about the thickness, there are two standard thicknesses of plasterboard - 9.5 mm and 12.5 mm. The sizes of plasterboard for ceilings are 9.5 mm or 10 mm. Most individuals tend to assume that the thicker the plasterboard the better, but this is absolutely false. A thicker plasterboard will only stick harder to the ceiling which will make it hard to seal joints if required.

Plasterboards are a great noise insulators which can also reduce disturbances from other activities. As a result, for walls, size of plasterboards that’s considered appropriate for walls is 12.5 mm or 13 mm.

Artex simply refers to a surface coating that’s commonly incorporated for interior decorating. Although it’s usually found on ceilings but it can also be used on the walls as well. The surface coating enables the professional plasterer or decorator add both texture as well as patterns to it. Originally, the name “Artex is the trademark of a UK based company known as Artex Ltd. Over time, the Artex name has been used to refer to all textured coatings, although there are other businesses that manufacture and sell identical products.

You can find Artex on ceilings as well as walls of mainly residential properties. In the 70’s and 80’s, it was pretty much a trend to have either your wall or ceiling ( can be both ) covered with Artex. The surface coating can be incorporated to create raised, textured swirls as well as patterns on ceiling and walls. There are a number of different patterns that can be made using Artex and some of these includes the following: Broken leather, swirl, stipple, fan or shell as well as knifed plaster. It can also provide just a bobbly raised uneven patter appearance from top to bottom.

Artex is main put to use by mainly decorators ( mostly plasterers). This is a skilled job as it’s tedious to create uninformed patterns especially if you don’t know how or where to start. Although the skill of Artex is very much a trade that’s dying rapidly now, but it was pretty much in high demand especially in the 70’s and 80’s.
