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.

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.

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 Artex?

The short and simple answer to this question is yes, you can plaster over Artex. However, you must also note that plastering over Artex may not be the best choice as Artex is porous and as such, you’d have to detach the stripping so as to get a smooth and even coating. In the event whereby your ceilings or walls have Artex on them, you’ll have to smooth the Artex in order to obtain a plaster of solid coat.

✓ Preparing Artex for plastering. First and foremost, you’ll have to detach any bumps before you can plaster over the Artex. Do note that you don’t have to completely remove the Artex, all that’s needed is just enough to get a coat of plaster. Make use of a scraper to get rid of the bumps on various Artex designs like swirl and bark. Once you’re through getting rid of as much bumps as possible, there’s the need to seal the Artex due to the fact that it can absorb the moisture out of the plaster which will cut the time to get a good finish to little or nothing. You can use a PVA and water mix to do the job!

✓ The PVA mix. This is done to seal off the porous Artex in order to stop it from absorbing moisture from your plaster which can make it start to crack and crumble. To do this, simply mix half PVA and half water, then use a brush to paint the mixture over the plastering area. Once done, you can give the plastering surface about two to three coats and wait for the solution to dry off within a hour or two.

Plastering over Artex is not as hard as it seems, but if you lack the confidence to complete the task, simply contact a professional for help.

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.
