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.

If you’re looking to plaster your ceiling, one of the most essential parts of the process is cutting the plasterboard. Once you’re able to master this skill, the rest of the plastering is quite easy. This is a task that can be done by any competent DIYer but with a little bit of patience and confidence. If you lack any of these attributes, we’d strongly recommend you call in a reliable professional who can guarantee the best results for help. In this guide, we’re going to take you through the plasterboard ceiling cutting process. Let’s take a look!

To cut plasterboard ceiling, you don’t need any expensive tool which is usually not the case when it comes to carpentry. If you won’t be cutting a lot of plasterboard, all you really need would be just an old handsaw or plasterboard one, a Stanley knife as well as a straight edge. However, if you’ll be cutting lots of plasterboards, you’ll require the following to make your task a lot easier:

✓ An old handsaw

✓ A Stanley knife and many spare blades

✓ A straight edge like a long spirit level

✓ A surform

✓ A battery drill and oh2 screwdriver bits, with specific plasterboard screws.

To cut plasterboard to length, you’ll have to first score a line on the face side of the board with a straight edge and Stanley knife. Once done, simply lift the sheet off the ground and snap it along the score line. Then, you can run your knife down the other side of the board , cutting the back of the plasterboard backing sheet. Upon completion, your plasterboard is now ready to be fitted on your ceiling.

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. In general, the standard plasterboard sheet size is 120 cm in width and within the range of 180 cm to 360 cm in height. 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.

It’s possible to paint your artex ceiling if you want to smarten it up or make it a different colour.

If it’s never been painted before, you’ll need to paint it with a PVA-based solution or water-thinned paint layer to start with. You may want to scrape or sand off any loose or peeling patches beforehand, but only do this if you’re sure that the artex doesn’t contain any asbestos.

Artex is a type of interior surface coating, similar to plaster. It’s used to create decorative textured finishes on ceilings and walls, so it takes longer to dry than plaster.

Artex is actually a brand name, but it’s used to refer to similar products made by other manufacturers too. It was particularly popular in the 1970s, but is still used to create attractive wall and ceiling finishes today.

The short and simple answer to this question is, it depends. Artex surface coating was manufactured with white abestos ( until the mid 1980’s ) in order to strengthen as well as harden it. In other words, this implies that all the ceilings and walls coverings made by Artex Ltd and other manufactures at the time are highly likely to contain asbestos. Although Artex Ltd stopped using asbestos as early as the mid 1980’s, there were still other manufacturers who continued using it until 1999 when the laws and regulations covering the use of asbestos changed in the year 2000.

Asbestos, however, is only harmful when disturbed and releases its deadly fibres. For instance, when it’s being sanded and removed as it usually poses no risks when left undisturbed. Since it’s not possible to identify Artex containing asbestos fibres with the naked eye, it’s strongly recommended that you hire the services of a qualified person or company to help determine if you have asbestos in your ceilings or walls especially if your house was constructed before the year 2000. The professionals will be able to advise you on the best course of action as well as if it’s dangerous.

To be sure if your Artex contains asbestos, you’ll need to have the artex sampled by an asbestos surveyor. If you’re planning to have a construction or maintenance work done on your property, and the artex is likely to be in the way or disturbed, there’s a need for you to have a refurbishment or demolition asbestos survey done. This will ensure that all the areas that’ll be disturbed by the work is properly tested to determine the presence or otherwise of asbestos. If found, the artex will have to be addressed and either removed or protected before any work can take place.
