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.

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.

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.

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.

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.

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.

Artex is a water based surface coating which is used to decorate both ceilings and walls with a textured finish. Back in the 1970’s, artex happens to be very popular when the swirling or spiky effects it creates  were considered to be the best of fashion when it comes to interior designs. However, in today’s world, an artex ceiling is not only considered outdated but also a pain to clean and repair.

If you have an artex ceiling in your residential property and looking for a way to get it off, then you’ve come to the right place. In this post, we’re going to show you how its done without much stress.

To get started you’d need to get the following tools and material which includes: safety goggles, dust mask and rubber gloves, plastic sheeting, canvas drop cloth ( carpet) or rosin paper (hard floor) and step ladder

Prepare the room. Start this by moving all furniture out of the room or stack the furniture at the centre of the room and cover using plastic sheets. Once done, cover all non-removable items with plastic sheets and lay down a canvas drop cloth for carpet floors and rosin paper for hard floors

• Put on your safety gear
• Use a utility knife or joint knife to slowly chip away at the texture and create a smooth surface.
• Mix joint compound in a bucket as per the instructions on the package
• Skim the surface with a thin layer of joint compound to smooth it out using a taping knife, then leave to dry overnight before you proceed
• Lightly sand the surface smooth with the help of a 220-grit sanding block
• Use a damp cloth to wipe the surface clean prior to painting.

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.
