Plasterboard or drywall is simply gypsum plaster covered from both sides by thick paper layers. It’s known to be a highly versatile product used on both interior walls and ceiling as a result of its numerous advantages. This popular material in residential buildings can be designed to be fire resistant, humidity resistant and noise resistant. They have a low impact on the environment, while also being quite easy to repair and perfect to hide stuffs from plain sight. Most home and property owners in the UK have this material installed in their space as despite the multiple benefits, they’re also quite affordable. However, if you’re thinking about installing a plasterboard on your ceiling, one challenge you’re likely to face is determining the appropriate plasterboard thickness to incorporate as this make or mar your entire project. In this post, we’re going to take a look at the right plasterboard thickness for ceiling so as to help you make an informed decision moving forward. Let’s take a look!

Firstly, let’s consider the size of the plasterboard sheet. 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.

Although they’re pretty much outdated now, artex happens to be a very popular surface coating option just a few decades ago.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.

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.

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.

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 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.

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.

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.
