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.

Can You Plaster Over WallPaper?

If you have wallpaper installed on your wall surface and you’re considering plastering the wall, when you put into consideration the stress involved in removing a wallpaper you may want to consider plastering directly over the wallpaper. This is quite understandable as removing a wallpaper can be quite time consuming and tedious, but plastering directly over wallpaper is a mistake that should never be made. Plastering over wallpaper is in no way a viable option due to the fact that it can only turn out disastrous after a couple of weeks or even days in some cases as the plaster will crack and crumble. As a result, you’ll have to firstly scrape off the wallpaper in order to assist the plaster get to be firmly secured to the wall behind.

When you plaster over a wallpaper, this will make the wallpaper wet and it’ll absorb the moisture. And once the plaster does not have moisture, the only result is for it to crack and start to crumble. Hence, plaster and wallpaper is never a good combination.

Asides from cracking and crumbling, anther issue is that the wallpaper will bubble. You can actually key the wallpaper with the help of a knife and it might look secured for some time, however it’ll eventually crumble and you’d have to scrape off the plaster complete to start all over again. The wallpaper will bubble as the plaster can’t be keyed into a wallpaper and the wallpaper will only work as a barrier between the plaster and the wall.

Overall, plaster always needs to slowly dry off as well as a good and proper surface to grip to. No matter the amount of PVA mix you spread on the wallpaper, it will always remain a barrier. So you’d have to remove the wallpaper completely to get a great result.

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 commonly referred to as drywall, plasterboard is an incredibly versatile product which features a sandwich of gypsum plaster between thick paper layers. It’s mainly used on both walls and ceilings due to the wide range of benefits it provides. Not only can plasterboard be made to be humidity resistant, fire resistant as well as noise resistant, but they’re also known to have a low environment impact, easy to repair and can be used to conceal stuff from plain sight. As a result of these benefits couple with the fact that they also happen to be quite affordable, plasterboard has grown to become a ubiquitous phenomenon in modern residential buildings.

When it comes to the installation of plasterboard on ceilings, one of the major sources of concern for several homeowners is the determination of the thickness required to ensure a durable and long-lasting project. If you’re planning to fit plasterboard on your ceiling and wondering the thickness that’ll be appropriate, then you’ve come to the right place. In this post, we’re going to give you a good insight on what plasterboard to use for ceilings. Let’s take a look!

First and foremost, 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.

The fact is several buildings contain artex as well as other textured coating on walls and ceilings which are all likely to contain asbestos. However, artex itself is not the main threat here but the potentially deadly harmful fibres that’s contained in it. In this post, we’re going to look at whether or not artex truly contains the deadly abestos.

The short and simply answer to this question is yes, artex can definitely contain asbestos, however not all artex will contain asbestos. The main reason asbestos was a popular construction material is because it was not only cheap and strong but also because it was very durable and long lasting. It was used in numerous construction materials ( which includes artex ) before it was finally banned in the year 1999. unfortunately during the time when artex was very popular in the 60’s, 70’s as well as 80’s, asbestos was still very much in use during the period. And as a result, a lot of the artex incorporated during that period will contain the deadly asbestos fibres. However, this does not only apply to artex, but also other textured coatings containing asbestos were incorporated in construction until 1999 when asbestos was formerly banned in the UK. These asbestos containing materials are often used on walls as well as ceilings of residential properties.

Unfortunately, it’s not possible to know an asbestos containing artex just by looking at it. In order to determine whether or not an artex contains the deadly asbestos fibres, it’ll have to be sampled and tested in a laboratory. What’s more? While several artex contains asbestos, asbestos free artex was available from the 1970s. However, since it’s impossible to determine using the naked eye, all artex installed before the ban will be assumed to contain asbestos.

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.

Installing a plasterboard to a ceiling is not the easiest of tasks, and even though it can be done by one person, it’s usually a lot easier when done by two people. If you’re an experienced DIYer, this task becomes a lot easier to undertake, with both confidence and patience needed to ensure a successful outcome. If you lack these essential 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 processes involved to plasterboard your ceiling. Let’s take a look!

✓ Take a measurement of your ceiling. Knowing the length and width of your room is crucial here. You have nothing to worry about if it’s not a perfect square as that’ll only mean more cutting.

✓ Make the necessary plasterboard cuts. Cut the plasterboard sheet with a utility knife in accordance to ceiling space measured.

✓ Remove existing plaster. Once done, examine the trusses and beams to ensure they’re still in a great condition before you proceed. Also, make sure there’s no loose plaster that can compromise your new installation.

✓ Apply construction adhesive. For a better fit, you’d have to apply adhesive along the beams while also avoiding the edges as this could affect your screw placement.

✓ Start in a level corner. You have to start the installation from the most level corner.

✓ Work along the outside edges. Secure it using a screw along the outside edge. This will make your plasterboard held to your ceiling perfectly. It won’t bend or break as your proceed with the installation.

✓ Complete the installation. Install the plasterboard on your entire ceiling and complete the installation by taping the seams and plastering for a smooth surface.

Plastering is suitable to cover most Artex. If it’s shallow Artex, it may be covered by skimming plaster on top. If the pattern of the Artex is too deep, you may need to use plasterboard to cover it or if you want to remove it entirely, you will need to use a wallpaper steamer.
