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.

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 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.

There are several different kinds of plastering. ‘Dot and dab’ refers to a base layer of plasterboard which is attached to a wall using ‘dabs’ of adhesive. ‘Floating’ is a technique where a backing or undercoat plaster is applied to walls. ‘Skimming’ or ‘reskimming’ refers to the very thin final decorative layer of plaster.

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.

It’s possible to paint your artex ceiling if you want to smarten it up or make it a different colour.

If it’s never been painted before, you’ll need to paint it with a PVA-based solution or water-thinned paint layer to start with. You may want to scrape or sand off any loose or peeling patches beforehand, but only do this if you’re sure that the artex doesn’t contain any asbestos.

Once you’ve done this, follow with two coats of your paint of choice – ideally an emulsion. If your artex ceiling has been painted before then you can paint directly without priming. However, if you’re painting over a particularly bold colour with a lighter one, you might want apply a layer of white paint first.

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.
