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.

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 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.

Plastering will fix small cracks in walls. Very small cracks may be fixed by simply reskimming plaster. More serious cracks will usually mean that you need to use new plasterboard or backing plaster. Larger jobs or deep cracks may need an experienced plasterer to come in.

Artexing a ceiling can be a tricky job, but whether you’re considering hiring a professional or DIY, it’s helpful to know how it’s done.

Artex is available either in a paste or powder form. The paste is ideal if you’re making small repairs or additions to an existing ceiling. But, if you have a whole ceiling to cover, the powder is more cost effective. When you’re ready to get started, you’ll need to mix the powder up with cold water according to the instructions.

It’s possible to artex over plaster, plasterboard or paint. If you have a plasterboard surface, you should tape and fill any joints or cracks before you begin. Plaster and plasterboard both require a coat of sealant or primer first. You can usually artex straight over paint, but any gloss paint should be sanded down, and any dark paints covered with a layer of white.

Artexing can get quite messy, so make sure you empty the room you’re working in as much as possible, lay down sheets and wear protective clothing and glasses. You might want to practice on a piece of board before you start on the ceiling.

Start by using a brush or roller to cover a 500 square cm area with a generous layer of artex. Then use a brush, comb or roller to create your chosen texture. Every time you do a new section of ceiling, try to blend it with the other sections you’ve done. Don’t be tempted to cover the whole ceiling before you start adding texture – the artex will dry too quickly for you to do it all in time.

Artex usually needs 12-24 hours in a well-ventilated space to dry completely.

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.

Prior to removing artex on your ceiling, it’s always crucial to determine whether or not the surface coating material contains asbestos. Asides from this, you may also wish to know how much you’re going to have the asbestos artex ceiling removed. If yes, then you’ve come to the right place! In order to help you make the best informed decision possible, this post was written to help give you an idea of the price it’s going to cost to remove asbestos artex ceiling in the UK.

Unfortunately, as simple as it seems, there’s no single straightforward answer to this question as there are many factors that can affect the cost of hiring an asbestos artex removal professional. These factors include the project’s scale, the complexity of the area which needs to be removed as well as the need for extra materials. Generally, professional artex removal companies charge a standard rate for their labour. As a result, you can always predict that the tradesperson’s labour will be more costly based on the extent of the job. Therefore, the more costly the labour fees will be if the job takes longer time to complete.

On the average, a tradesperson will charge within the range of £250 to £400 on a daily basis to undertake the project for you. And of course, you can expect these rates to vary based on the company hired as well as the area you live in. For rxample, you can expect that a tradesperson’s charges would be higher in an area such as Central London, as opposed to other areas which are more rural.

Artex was originally made using white asbestos to make it stronger. However, this stopped in the mid-1980s, and the use of asbestos was banned in the UK in 1999, due to its extreme health risks. So, any artex you buy today won’t contain asbestos.

If you have an artex ceiling or wall that was created before 1999, it may have asbestos in it. This won’t be a health hazard if you leave it undisturbed, so it’s not necessary to remove it. However, if you want to get rid of or alter your artex ceiling or wall, you must get it tested to check if it has asbestos in or not first. If it does, you’ll need to hire a qualified professional to work on it.
