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.

Installing a plasterboard on your ceiling is a cool way to modernize your property. Over the past couple of decades, there has bee an increasing number of trends associated with plastering of both walls and ceilings such as rounded edges and textured plaster. However, in recent times, home and property owners are now looking to install more of sharp edges. If you’re planning to plaster your ceiling, you’d probably want to know just how much this project is going to cost. If yes, then you’ve come to the right place. In this article, we’ll give you a rough estimate of ceiling plastering costs.

There are a plethora of factors the can influence the price of plastering your ceiling. These pricing components includes the following:

✓ Size. As you would have expected, the larger the job, the more the overall cost. However, the price per square metre will reduce which means that the cost of plastering a small ceiling space will cost more per square metre than the cost of plastering a larger ceiling space per square metre.

✓ Materials. We have a wide range of plasterboard available in the market. If you need a fire retardant, acoustic or other types of specialist plasterboard, you can expect to pay higher than standard plasterboards.

✓ Location. Just like many other home improvement projects, the cost of plastering ceiling varies greatly throughout the UK. Places such as London and the South East have the highest prices due to the high standard of living as well as greater demands.

In general, to plaster a ceiling (small 2 m x 2 m) - overboard and plaster will cost within the range of £200 to about £300. Also, to plaster a ceiling (large 5 m x 6 m) - overboard and plaster will cost within the range of £400 to about £600. The average plasterer’s daily rate (including material) is about £180 to £300 and ceiling plastering cost per square metre ranges between £20 to £40.

Plasterboard or drywall is simply gypsum plaster covered from both sides by thick paper layers. It’s known to be a highly versatile product used on both interior walls and ceiling as a result of its numerous advantages. This popular material in residential buildings can be designed to be fire resistant, humidity resistant and noise resistant. They have a low impact on the environment, while also being quite easy to repair and perfect to hide stuffs from plain sight. Most home and property owners in the UK have this material installed in their space as despite the multiple benefits, they’re also quite affordable. However, if you’re thinking about installing a plasterboard on your ceiling, one challenge you’re likely to face is determining the appropriate plasterboard thickness to incorporate as this make or mar your entire project. In this post, we’re going to take a look at the right plasterboard thickness for ceiling so as to help you make an informed decision moving forward. Let’s take a look!

Firstly, let’s consider the size of the plasterboard sheet. 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.

Artex is a water based decorative surface coating is typically incorporated on both walls and ceilings so as to apply a pattern. During the peak of its popularity in the 1970’s, it was considered the height of fashion when it comes to interior wall designs however its major drawback remains the fact that it usually contains asbestos especially if it was manufactured before the laws governing the use of asbestos was changed in the year 2000. And asbestos, as we know it, can be deadly when disturbed and its fibres are inhaled.

If you have artex installed in your purchased property and you do not know when the artex walls were done, or perhaps you just want to change the aesthetic design of your home into something more modern and to your personal taste, then you may want to remove the existing artex from your property for good. If this is your wish then you’ve come to the right place.

To remove artex from your walls you can choose to do so using the steaming method or through the use of an external product.

Using the steaming method, you should know that it’ll be more labour intensive and time consuming. You need a lot of patience moving your steamer slow and steady because if left on a spot for too long can damage the wall behind the coating. Once the artex has been dampened with the steamer, you can then scrape them off with a handheld scraper.

A faster solution would be to use an external product to remove your artex.  For example, you can use X-Tex which is a water-based coating remover. All you need to do is paint the substance over your artex wall and leave to dry for about 30 to 60 minutes before peeling away the artex.

How Much Does Plastering Cost?

If your existing interior or exterior plaster is starting to show signs of needing to be refreshed or the painting never seems to last, then it’s probably time to have your plaster renewed to breathe in a new lease of life to your decorating efforts.

So if you’re giving wall plastering a thought, there’s a need to have a rough estimate of the cost a professional is likely to charge so you can set a budget and start planning. However a direct answer can not be provided for this question as there are so many factors that a professional will put into considering before coming up with a quote that’s unique to your specific requirements.

A lot of plasterers will come up with a quote for the job using the number of square metres of wall space that’s going to be covered. This is due to the number of plasterboards as well as the other materials that the plasterer will need to purchase, how long the work will take and also the labour that’ll be involved in completing the project.

Another popular influencing factor that several plasterers use is the size of the room to be plastered. This is the main reason why you’re more likely to find the prices in small, medium as well as large rooms. Therefore, in order to have a more accurate estimate of the cost of your plastering project, you’d have to call in a qualified professional to have a look at the job at hand. Generally, to re-plaster a small room will cost within the range of £350 to £550, a medium room will cost within the range of £400 to £600 and a large room, between £550 to £700.

Although they’re pretty much outdated now, artex happens to be a very popular surface coating option just a few decades ago. Several homeowners with artex in recent times would either want to have them removed or cover them up with stuffs such as a wallpaper. So if you’re wondering whether or not it’s possible to wallpaper over artex, then there you have it. It’s possible to wallpaper over artex, however it’s not advisable as wallpaper may eventually crack over time. On the other hand, the artex can also create ridges beneath the wallpaper which allows unpleasant protrusions in the wallpaper. Instead of applying wallpaper over artex, a more permanent solution would be to cover it with drywall or wet plaster or perhaps just have it removed completely.

There are two types of wallpaper, there’s the thin wallpaper application which comes with adhesive on one side as well as a pattern or colour on the other side. With this, all you need do is simply to peel and stick. Then the other type is the sturdier wallpaper that’s more thick and requires a special wallpaper paste. However, it’s important to note that if you choose to wallpaper over your artex, you won’t be able to make use of the thin type of wallpaper, rather you’ll have to incorporate the sturdier  option which makes use of wallpaper paste.

The wallpaper paste is the product you mix with water to produce a paste which you’ll have to apply to your walls before applying the applying the regular wallpaper - one without adhesive on one side. Appling wallpaper to an artex decoration may just give you the updated appearance you so much desire.

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.
