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.

Cutting a plasterboard is a relatively simple process requiring only some basic tools. Unfortunately, the lack of knowledge serves as big deterrent for many people who wishes to put it to good use. Plasterboard can actually be sawn using an ordinary timber saw that’s fine-toothed to get a cleaner edge. However, the basic tools you may also need includes a sharp knife (Stanley Knife), pencil, a fine sandpaper, a straight edge and measurement tape as well as a wall board saw. Let’s have a look at the cutting process!

✓ Firstly, you need to put the plasterboard sheet flat on a firm surface.

✓ Use the tape measurement to measure the cut you wish to make.

✓ With the help of a pencil, simply mark out the part you wish to cut on the plasterboard’s front side.

✓ Once marked, place a spirited level over the marked spot on the plasterboard sheet you want to cut.

✓ Cut a shallow mark into the plasterboard sheet using the Stanley Knife to cut along the edge.

✓ The cut should be slow and gradual to ensure you do not wander off the edge of the marked area.

✓ Once the shallow cut has been made, turn the plasterboard sheet on its edge and deliver a quick and sharp push towards the plasterboard’s back and on one side of the cut.

✓ Place the plasterboard sheet backing against a flat surface ensuring the line of the cut is over an edge. Once done, give a quick and sharp push towards the back of the plasterboard sheet and on the part of the board is reaches beyond the edge.

✓ Using a fine sandpaper, remove all forms of paper burrs.

The process of cutting plasterboard requires a lot of practice. If you lack the training and experience, the cutting process is best left to a proficient professional who can guarantee the best results the first time and save you some additional costs due to potential damages.

Artex is a water based decorative surface coating is typically incorporated on both walls and ceilings so as to apply a pattern. During the peak of its popularity in the 1970’s, it was considered the height of fashion when it comes to interior wall designs however its major drawback remains the fact that it usually contains asbestos especially if it was manufactured before the laws governing the use of asbestos was changed in the year 2000. And asbestos, as we know it, can be deadly when disturbed and its fibres are inhaled.

If you have artex installed in your purchased property and you do not know when the artex walls were done, or perhaps you just want to change the aesthetic design of your home into something more modern and to your personal taste, then you may want to remove the existing artex from your property for good. If this is your wish then you’ve come to the right place.

To remove artex from your walls you can choose to do so using the steaming method or through the use of an external product.

Using the steaming method, you should know that it’ll be more labour intensive and time consuming. You need a lot of patience moving your steamer slow and steady because if left on a spot for too long can damage the wall behind the coating. Once the artex has been dampened with the steamer, you can then scrape them off with a handheld scraper.

A faster solution would be to use an external product to remove your artex.  For example, you can use X-Tex which is a water-based coating remover. All you need to do is paint the substance over your artex wall and leave to dry for about 30 to 60 minutes before peeling away the artex.

✓ Apply the plaster onto the wall. Upon cleaning of the walls and successful mixture of the plaster, the next step is to apply the mixture to the wall using the hawk board, trowels and a floating tool.

✓ Skim and smooth. After the the first coat has dried after waiting for about 30 minutes, the next step will be to wipe out the bumps and lumps using a trowel to smooth over the surface. Once this is done you can then scrape the wall with a devilling float.

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.

Also referred to as drywall, plasterboard is a panel that features an inner layer of gypsum and spread between facer as well as backer paper. It is mostly incorporated in the construction of both interior walls and ceilings. Plasterboard can be made to be humidity resistant, fire resistant as well as noise resistant. Due to these reasons and also the fact that it’s very easy to install and very affordable, plasterboard is a very popular choice when it comes to interior walls and ceilings.

One of the major issues that most homeowners face when fitting plasterboard is the thickness required to make the project a long lasting one. But not to worry, we got you covered! If you’re about to install plasterboard for your ceiling and wondering the thickness that’ll be appropriate, then you’ve come to the right place. In general, 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.

Plasterboards are a great noise insulators which can also reduce disturbances from other activities. As a result, for walls, size of plasterboards that’s considered appropriate for walls is 12.5 mm or 13 mm.

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.
