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.

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. Nowadays, homeowners now prefer smooth plastered finishes over Artex, as they can be easily painted or wallpapered.

Can You Plaster Over Tiles?

Yes, it’s absolutely possible to plaster over tiles but just because is possible doesn’t mean you should. Plastering over tiles is an option but it’s not recommended by experts due to several reasons. A good example is the fact that a tiled environment is in no way a suitable environment that can serve as a good bonding surface for a plaster. For the success of a plastering project, there’s the need for the surface to be able to bond to the PVA base coat. Due to fact that most tiles are slippery in nature and also lack of the ability to be able to absorb moisture, the PVA base coat layer will not be able to bond to the tiled surface, which will ultimately make for a weak surface upon the application of the plaster. Consequently, the plaster will easily flake and fall from the wall.

The inability to drill into the tiled wall surface after plastering is one of the major disadvantages that also arises when you decide to plaster over tiled surfaces. Most tiled surfaces are found in kitchens and bathrooms which are going to need appliances such as sinks, lavatories, kitchen counters and lots more. These appliances are designed to be installed on solid surfaces which would not be an easy task to carry out on tiles knowing there would definitely be great cracks or damages.

The best tip you’ll get if you’re considering to plaster on a tiled surface, is that detaching tiles from a surface can easily be done with a hammer and chisel, and that would save you a host of problems later in the future. However, if you still wish to plaster on your tiled walls, then you best bet would be to get a Blue Grit bonding agent. It works better than PVA and only needs one coat.

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.

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.

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.

Cutting a plasterboard is a relatively simple process requiring only some basic tools. Unfortunately, the lack of knowledge serves as big deterrent for many people who wishes to put it to good use. Plasterboard can actually be sawn using an ordinary timber saw that’s fine-toothed to get a cleaner edge. However, the basic tools you may also need includes a sharp knife (Stanley Knife), pencil, a fine sandpaper, a straight edge and measurement tape as well as a wall board saw. Let’s have a look at the cutting process!

✓ Firstly, you need to put the plasterboard sheet flat on a firm surface.

✓ Use the tape measurement to measure the cut you wish to make.

✓ With the help of a pencil, simply mark out the part you wish to cut on the plasterboard’s front side.

✓ Once marked, place a spirited level over the marked spot on the plasterboard sheet you want to cut.

✓ Cut a shallow mark into the plasterboard sheet using the Stanley Knife to cut along the edge.

✓ The cut should be slow and gradual to ensure you do not wander off the edge of the marked area.

✓ Once the shallow cut has been made, turn the plasterboard sheet on its edge and deliver a quick and sharp push towards the plasterboard’s back and on one side of the cut.

✓ Place the plasterboard sheet backing against a flat surface ensuring the line of the cut is over an edge. Once done, give a quick and sharp push towards the back of the plasterboard sheet and on the part of the board is reaches beyond the edge.

✓ Using a fine sandpaper, remove all forms of paper burrs.

The process of cutting plasterboard requires a lot of practice. If you lack the training and experience, the cutting process is best left to a proficient professional who can guarantee the best results the first time and save you some additional costs due to potential damages.
